Muchos operarios de planta 1 se han encontrado con este incidente y, ante ello, han retirado el anillo de molienda y cambiado el rodillo de molienda, dedicando varias horas a ello sin resultado. De hecho, la verdadera causa del problema suele estar en el desequilibrio del flujo de aire interno. Este art\u00edculo te proporcionar\u00e1 una comprensi\u00f3n exhaustiva de los consejos de resoluci\u00f3n r\u00e1pida de problemas que utilizan los mejores ingenieros de mantenimiento.

Tras haber gestionado m\u00e1s de 300 paradas repentinas, he resumido un conjunto de principios denominados \u201cm\u00e9todo de diagn\u00f3stico 4V\u201d (vibraci\u00f3n, volumen de salida, velocidad del viento y aspecto visual). Este modelo mental te obliga a comprender los par\u00e1metros operativos m\u00e1s cr\u00edticos antes de siquiera coger la llave inglesa.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">1. Vibraciones (\u00bfSe trata de un fallo mec\u00e1nico o de un problema con el material?)<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Si la m\u00e1quina vibra mucho, la causa m\u00e1s probable suele ser que la capa de material no est\u00e9 distribuida de manera uniforme o que haya alguna pieza met\u00e1lica rota en su interior.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">F\u00edjate primero en la cantidad de material de alimentaci\u00f3n. Si hay falta de material en la c\u00e1mara de molienda, el rodillo y el anillo de molienda chocar\u00e1n directamente con fuerza. En ese momento, oir\u00e1s un ruido met\u00e1lico de fricci\u00f3n especialmente estridente y la m\u00e1quina tambi\u00e9n sufrir\u00e1 sacudidas violentas. Si la alimentaci\u00f3n no presenta ning\u00fan problema, se trata de una aver\u00eda mec\u00e1nica. Por ejemplo, el eje del pasador de suspensi\u00f3n est\u00e1 muy desgastado y el bastidor en forma de flor de ciruelo est\u00e1 roto, lo que destruir\u00e1 por completo el equilibrio centr\u00edfugo del sistema. En este caso, no te lo pienses: det\u00e9n la m\u00e1quina y cambia las piezas.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">2. Rendimiento (ca\u00edda repentina del rendimiento en nieve polvo)<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Cuando el caudal disminuye, significa que la tuber\u00eda est\u00e1 obstruida o que las piezas de trituraci\u00f3n est\u00e1n desgastadas hasta el l\u00edmite.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Presta especial atenci\u00f3n a la comprobaci\u00f3n del conducto de retorno y del colector cicl\u00f3nico. Si la materia prima est\u00e1 demasiado h\u00fameda, se pegar\u00e1 a la pared interior del colector cicl\u00f3nico, atascando el \u201ccuello\u201d, lo que impedir\u00e1 que el polvo molido salga por la v\u00e1lvula de descarga. Recuerda esta frase: independientemente de la configuraci\u00f3n del molino Raymond que est\u00e9s reparando, limpia la v\u00e1lvula de cierre herm\u00e9tico (con el ventilador apagado) del colector cicl\u00f3nico antes de pensar que el rodillo de molienda no funciona.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">3. Velocidad del viento (el flujo de aire y la presi\u00f3n del viento no coinciden)<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Si la presi\u00f3n del aire del ventilador no es suficiente, los materiales triturados quedar\u00e1n completamente atrapados en el motor principal y no podr\u00e1n salir.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Echa un vistazo al man\u00f3metro de la salida del ventilador. Si la presi\u00f3n est\u00e1tica desciende, significa que hay una fuga en el sistema de conductos o que el impulsor del ventilador est\u00e1 muy desgastado. En cuanto la temperatura interior es elevada, la velocidad del aire desciende a 1. La combinaci\u00f3n de estos dos factores suele provocar directamente la activaci\u00f3n de la protecci\u00f3n t\u00e9rmica.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">4. Aspecto (el grado de finura no cumple con los est\u00e1ndares y el orificio de escape deja escapar cenizas al exterior)<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">\u00bfEl polvo es demasiado grueso? No te lo pienses dos veces, ve directamente a comprobar el analizador. Si la correa del variador est\u00e1 floja o la cuchilla del analizador se ha bajado, las part\u00edculas grandes se colar\u00e1n por la zona de selecci\u00f3n de polvo y saldr\u00e1n directamente por la puerta trasera.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A continuaci\u00f3n, comprueba si el conducto de escape acumula mucho polvo. El sistema deja escapar cenizas, lo que significa que el filtro de mangas por impulsos est\u00e1 quemado o que la manga interior est\u00e1 rota, lo que alterar\u00e1 directamente el entorno de presi\u00f3n negativa de todo el sistema de circulaci\u00f3n.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img title=\"Diagrama de flujo de la matriz de diagn\u00f3stico 4-V, con las v\u00edas de exploraci\u00f3n espec\u00edficas y los indicadores clave se\u00f1alados.\" loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"576\" src=\"https:\/\/www.clirik.com\/wp-content\/uploads\/2026\/08\/pasted-image-20260804-060355-638-1024x576.png\" alt=\"Diagrama de flujo de la matriz de diagn\u00f3stico 4-V, con las v\u00edas de exploraci\u00f3n espec\u00edficas y los indicadores clave se\u00f1alados.\" class=\"wp-image-10212\" srcset=\"https:\/\/www.clirik.com\/wp-content\/uploads\/2026\/08\/pasted-image-20260804-060355-638-1024x576.png 1024w, https:\/\/www.clirik.com\/wp-content\/uploads\/2026\/08\/pasted-image-20260804-060355-638-300x169.png 300w, https:\/\/www.clirik.com\/wp-content\/uploads\/2026\/08\/pasted-image-20260804-060355-638-768x432.png 768w, https:\/\/www.clirik.com\/wp-content\/uploads\/2026\/08\/pasted-image-20260804-060355-638-1536x864.png 1536w, https:\/\/www.clirik.com\/wp-content\/uploads\/2026\/08\/pasted-image-20260804-060355-638-18x10.png 18w, https:\/\/www.clirik.com\/wp-content\/uploads\/2026\/08\/pasted-image-20260804-060355-638.png 1672w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Common_component_failures_and_hard_core_solutions\"><\/span>Fallos habituales de los componentes y soluciones definitivas<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">La reparaci\u00f3n de la m\u00e1quina debe adaptarse a cada caso concreto, y lo \u00fanico que se ahorra es dinero real y tiempo de producci\u00f3n de plata. A continuaci\u00f3n se enumeran algunos de los problemas m\u00e1s habituales de las m\u00e1quinas Raymond en condiciones de trabajo adversas, as\u00ed como medidas pr\u00e1cticas muy concretas.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">El an\u00e1lisis del desequilibrio del flujo de aire provoca el engrosamiento del polvo.<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Ajustando la holgura de las palas del analizador, se puede resolver el problema del tama\u00f1o de las part\u00edculas del modelo 80%. A muchos t\u00e9cnicos les gusta aumentar constantemente la velocidad del motor del analizador, intentando forzar la salida del polvo fino. Pero hay un gran inconveniente: si las cuchillas del interior se desgastan de forma desigual, el motor se sobrecalentar\u00e1 en cuesti\u00f3n de minutos, como podr\u00e1s comprobar.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Lo correcto es desconectar la alimentaci\u00f3n el\u00e9ctrica y utilizar una regla para medir la distancia entre la cuchilla y la carcasa del analizador. Si la distancia supera los 5 mm, no dudes en cambiar las cuchillas directamente. Adem\u00e1s, hay que comprobar que los par\u00e1metros del variador de frecuencia (VFD) se ajusten a la densidad relativa del material que se est\u00e1 alimentando en ese momento.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Temperatura elevada provocada por un desgaste an\u00f3malo del rodillo de molienda y del anillo de molienda<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Si el anillo de molienda presenta ranuras de diferentes profundidades, debe volver a mecanizarse o sustituirse inmediatamente. El rodillo de molienda hace rodar el material por la fuerza centr\u00edfuga. Si se mezclan accidentalmente objetos duros, como bloques de hierro, se formar\u00e1n profundas hendiduras en la superficie del anillo de molienda. Estas hendiduras da\u00f1ar\u00e1n la capa de material, lo que provocar\u00e1 un aumento vertiginoso de la fricci\u00f3n local y har\u00e1 que la temperatura de la carcasa supere los 90 \u2103.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Cuando esto ocurra, abre la puerta de acceso y comprueba la superficie de desgaste a simple vista. Si deseas sustituirlos, lo mejor es cambiar el anillo de molienda y el juego de rodillos de molienda, con el fin de mantener la mejor superficie de contacto de molienda.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Comparaci\u00f3n entre las tasas de desgaste normales y las anormales<\/h3>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><tbody><tr><td>Componente<\/td><td>\u00cdndice de desgaste normal \/ Estado<\/td><td>\u00cdndice de desgaste anormal \/ Estado<\/td><td>Horario de apertura (estimado)*<\/td><td>Espesor \/ holgura recomendados para la sustituci\u00f3n<\/td><\/tr><tr><td><strong>Palas del clasificador<\/strong><\/td><td>Desgaste uniforme de los bordes; temperaturas estables del motor<\/td><td>Desgaste desigual; provoca el sobrecalentamiento del motor y la producci\u00f3n de polvo grueso<\/td><td>Entre 2.000 y 4.000 horas<\/td><td>Sustituya el juego de cuchillas cuando la holgura respecto a la carcasa supere&nbsp;<strong>5 mm<\/strong><\/td><\/tr><tr><td><strong>Anillo de rectificado<\/strong><\/td><td>Desgaste superficial suave y uniforme; temperaturas estables de la carcasa<\/td><td>Surcos de desgaste acelerado; hendiduras profundas causadas por part\u00edculas de hierro extra\u00f1as; temperaturas de la tuber\u00eda de revestimiento&nbsp;<strong>&gt; 90 \u00b0C<\/strong><\/td><td>4.000 \u2013 6.000 horas<\/td><td>Volver a mecanizar o sustituir inmediatamente en caso de surcos profundos.<\/td><\/tr><tr><td><strong>Rodillos de molienda<\/strong><\/td><td>Desgaste sim\u00e9trico; mantiene una geometr\u00eda de rectificado \u00f3ptima<\/td><td>Picos de fricci\u00f3n localizados; surcos profundos provocados por restos de hierro<\/td><td>4.000 \u2013 6.000 horas<\/td><td>Sustituir al mismo tiempo que el anillo de rectificado<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<h3 class=\"wp-block-heading\">Ventiladores y tuber\u00edas obstruidos<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Una limpieza a fondo de la tuber\u00eda puede eliminar directamente la contrapresi\u00f3n del sistema. Si la corriente del motor del ventilador se dispara de repente, significa que los materiales pesados que no se han clasificado se han depositado en el tubo horizontal.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Busca un martillo de goma para dar un golpecito en el tubo. Si el sonido es sordo, significa que est\u00e1 obstruido. Abre la boca de limpieza y retira los residuos acumulados. Al volver a ponerlo en marcha, recuerda ajustar el deflector de aire del ventilador para aumentar el caudal de aire en un 15% y as\u00ed evitar problemas antes de que se produzcan.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"A_Guide_to_Avoid_Pits_for_Insiders_%E2%80%9CButter_Trap%E2%80%9D_in_Daily_Maintenance%E2%80%9D\"><\/span>Gu\u00eda para evitar errores para expertos: \u201cLa trampa de la mantequilla\u201d en el mantenimiento diario\u201d<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Si se aplica demasiada mantequilla al conjunto de rodamientos del rodillo triturador, no solo se estropear\u00e1 el ret\u00e9n de aceite al instante, sino que tambi\u00e9n se provocar\u00e1 una contaminaci\u00f3n interna catastr\u00f3fica.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Muchos mec\u00e1nicos cometen un grave error. Les gusta aplicar una gran cantidad de grasa nueva en los componentes de los cojinetes cada d\u00eda. Siempre piensan que el equipo est\u00e1 sobrecargado y que un poco m\u00e1s de lubricaci\u00f3n no puede da\u00f1arlo. Esto es un grave error. Si hay demasiada grasa, la presi\u00f3n hidr\u00e1ulica quedar\u00e1 reprimida en su interior. El exceso de grasa se endurecer\u00e1 y presionar\u00e1 directamente sobre el ret\u00e9n de aceite de la parte inferior. Una vez que el ret\u00e9n de aceite se rompa, el polvo de piedra ultrafino penetrar\u00e1 en la cavidad del cojinete y se mezclar\u00e1 con la grasa, convirti\u00e9ndose en una \u201cpasta abrasiva\u201d muy destructiva.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">La pr\u00e1ctica habitual consiste en a\u00f1adir solo entre 50 y 70 gramos de grasa a base de litio para altas temperaturas por turno; bajo ninguna circunstancia debes caer en la tentaci\u00f3n de lubricar en exceso. Lo mejor es instalar engrasadores con funci\u00f3n autom\u00e1tica de alivio de presi\u00f3n, lo que elimina de ra\u00edz la posibilidad de que se produzcan errores humanos.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Actual_combat_case_a_%E2%80%9Cghost_fault%E2%80%9D_that_trips_every_three_hours%E2%80%9D\"><\/span>Caso real de combate: un \u201cfallo fantasma\u201d que se activa cada tres horas.\u201d<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">La situaci\u00f3n en la que hay que eliminar obst\u00e1culos es la que m\u00e1s miedo da a la hora de tomar decisiones. El oto\u00f1o pasado, el propietario de una f\u00e1brica de talco en la provincia de Shandong se vio en un aprieto. Su molino Raymon principal activaba la protecci\u00f3n t\u00e9rmica cada tres horas o m\u00e1s debido a la sobrecarga del motor principal, y el rendimiento era a\u00fan m\u00e1s lamentable. El jefe del equipo de mec\u00e1nicos in situ insisti\u00f3 en que el husillo estaba deformado y hab\u00eda averiado el cojinete. Incluso cogi\u00f3 los planos y estaba dispuesto a encargar decenas de miles de husillos nuevos en el mes de enero. Como m\u00ednimo, tendr\u00eda que paralizar el trabajo durante medio mes.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Una vez que nuestro equipo lleg\u00f3 al lugar, no tocamos el pozo principal en absoluto. Lo primero es poner en marcha el equipo y medir la presi\u00f3n del aire del sistema. Vaya, toda la tuber\u00eda de circulaci\u00f3n est\u00e1 llena de presi\u00f3n positiva y la interfaz est\u00e1 llena de polvo. No hay ning\u00fan tipo de entorno de presi\u00f3n negativa. Esto demuestra que el interior de la unidad principal est\u00e1 completamente obstruido por el polvo.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Tras localizar el extremo final a lo largo del conducto de aire, sali\u00f3 a la luz la verdad: el diafragma de la v\u00e1lvula solenoide del colector de polvo por impulsos llevaba mucho tiempo deteriorado y roto, lo que imped\u00eda que la bolsa de tela pudiera limpiar el polvo en absoluto. Cientos de bolsas de tela para la eliminaci\u00f3n de polvo se han acumulado en \u201cparedes de cemento\u201d de 1 que est\u00e1n completamente obstruidas. Los gases de escape no pueden salir. El motor principal solo puede transportar y remover polvo de piedra con una resistencia enorme. Es extra\u00f1o que el motor no se dispare.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u00bfC\u00f3mo lo resolviste al final? Gast\u00e9 unas decenas de d\u00f3lares en cambiar el diafragma de una v\u00e1lvula solenoide y di varios golpes manuales para limpiar la bolsa. En menos de media hora, tanto antes como despu\u00e9s, el equipo se reinici\u00f3, la corriente se mantuvo tan estable como un perro viejo y nunca volvi\u00f3 a saltar el fusible. Este contratiempo confirma una vez m\u00e1s una regla de oro: cuando te encuentres con un problema en un coche, comprueba primero el circuito de combustible y no sospeches a la ligera de las grandes piezas mec\u00e1nicas.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Frequently_Asked_Questions_FAQ\"><\/span>Preguntas frecuentes (FAQ)<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<h3 class=\"wp-block-heading\">\u00bfPor qu\u00e9 mi molino Raymond vibra tanto?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">La alimentaci\u00f3n no es uniforme o la materia prima es demasiado dura, lo que provoca la formaci\u00f3n de una capa estable entre el rodillo de molienda y el anillo de molienda. Ajusta la velocidad del alimentador y, de paso, comprueba si se han introducido restos met\u00e1licos en la c\u00e1mara de molienda.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">\u00bfC\u00f3mo ajustar la densidad del polvo?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Cambia la velocidad del separador superior (analizador). Si se aumenta la velocidad, el polvo se volver\u00e1 m\u00e1s fino. Si se reduce la velocidad, las part\u00edculas grandes se acumular\u00e1n y el polvo se volver\u00e1 m\u00e1s grueso.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">\u00bfA qu\u00e9 se debe que la corriente principal del motor sea demasiado alta?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">O bien la alimentaci\u00f3n est\u00e1 obstruida, o bien el conducto de aire de retorno est\u00e1 bloqueado, lo que provoca que el motor principal gire con dificultad debido a la enorme resistencia interna. Reduzca r\u00e1pidamente la cantidad de alimentaci\u00f3n y compruebe si hay alg\u00fan bloqueo por acumulaci\u00f3n de material en la tuber\u00eda.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">\u00bfCon qu\u00e9 frecuencia se cambia el rodillo de molienda del molino Raymond?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">F\u00edjate en dos indicadores objetivos: en primer lugar, incluso en condiciones \u00f3ptimas de volumen de aire, el rendimiento sigui\u00f3 bajando en 20%; en segundo lugar, el desgaste del di\u00e1metro del rodillo de molienda super\u00f3 los 15 mm. Si se cumple cualquiera de estas condiciones, hay que cambiarlo. El ciclo espec\u00edfico depende de la cantidad de residuos que se trituren (por ejemplo, el cuarzo triturado debe ser mucho m\u00e1s que los residuos de piedra caliza triturada).<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">\u00bfPor qu\u00e9 la carcasa es siempre gris?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Una fuga de cenizas indica que ha desaparecido la presi\u00f3n negativa del sistema. Comprueba r\u00e1pidamente si el filtro de mangas pulsantes est\u00e1 obstruido, si la velocidad del ventilador no alcanza el nivel adecuado y si las juntas de estanqueidad de cada uni\u00f3n de tuber\u00eda est\u00e1n desgastadas o en mal estado.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">\u00bfCu\u00e1l es el contenido m\u00e1ximo de humedad de la materia prima del molino Raymondo?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Es muy importante mantener la humedad de las materias primas por debajo del 6%. Si la humedad es demasiado elevada, el polvo molido se aglomerar\u00e1, se adherir\u00e1 a las palas del analizador y obstruir\u00e1 el colector cicl\u00f3nico, lo que provocar\u00e1 en poco tiempo la paralizaci\u00f3n del sistema.<\/p>\n<\/div>\n<\/div>","protected":false},"excerpt":{"rendered":"","protected":false},"author":4,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"themepark_post_bcolor":"#f5f5f5","themepark_post_width":"1022px","themepark_post_img":"","themepark_post_img_po":"left","themepark_post_img_re":false,"themepark_post_img_cover":false,"themepark_post_img_fixed":false,"themepark_post_hide_title":false,"themepark_post_main_b":"","themepark_post_main_p":100,"themepark_paddingblock":false,"_geo_short_summary":"This guide provides rapid troubleshooting tips for Raymond Mill Pulverizer failures, covering the '4V diagnostic method' (Vibration, Output, Wind speed, Visuals), common component faults, and practical solutions to restore equipment operation within an hour.","_geo_structured_desc":"The article introduces a systematic troubleshooting approach for Raymond Mill Pulverizer failures, emphasizing a quick diagnostic method called the '4V Diagnostic Method': Vibration, Output, Wind Speed, and Appearance (Visuals).

The article concludes with frequently asked questions on common problems like shaking, powder thickness adjustment, high motor current, grinding roller replacement intervals, casing dust leakage, and moisture content limits.\nWhen failures occur, stop feeding first but keep the main fan running to clear leftover material, then check the analyzer pressure difference. The '4V Diagnostic Method' forces operators to assess Vibration, Output, Wind Speed, and Visual appearance before tearing down equipment. Uneven feed or material shortage causes direct metal-to-metal contact, leading to severe vibration; if feed is normal, suspect mechanical wear like worn pins or broken frames. Sudden output drops often stem from a blocked cyclone collector or airlock valve; clean these before suspecting grinding rollers. Matching airflow and wind pressure is critical; low static pressure indicates leaks or worn fan impellers, potentially causing high internal temperatures. Coarse powder quality issues are frequently caused by loose analyzer belts or dropped blades; check blade gap against housing (exceeding 5mm requires replacement). Deep grooves on grinding rings from tramp iron force casing temperatures above 90\u00b0C; always replace grinding ring and rollers as a set. High fan motor current or a stuffy pipe sound indicates blockages; remove obstructions and increase air volume by 15% when restarting. Over-lubricating bearings is a common error; only add 50-70 grams of high-temperature lithium grease per shift to prevent seal failure and paste contamination. Intermittent thermal trips were solved by replacing a solenoid valve diaphragm in the pulse dust collector, proving the importance of checking the gas path first. Feed moisture must be kept below 6% to avoid agglomeration, sticking, and system blockage.\nWhy is my Raymond mill shaking so badly?\nThe shaking is usually caused by uneven feed or raw material that is too hard, preventing a stable material pad between the grinding roller and grinding ring. Adjust the feeder speed and check the grinding chamber for any metal debris.\nHow do I adjust the powder fineness (thickness)?\nChange the speed of the separator (analyzer).
