400 mesh -1250 mesh ore micro powder has many industrial needs and wide applications. Such as 400 mesh-1250 mesh talc powder used in the rubber industry, 400 mesh-1250 mesh gypsum powder used in the plastic industry, and 400 mesh-1250 mesh calcium carbonate powder used in pvc and stone papermaking, etc. It can be said that the amount of fine stone powder of 400 mesh to 1250 mesh is large. So how to choose 400 mesh-1250 mesh micro grinding mill?
We know that traditional Raymond mill cannot meet the needs of customers. Equipment such as Raymond mills and high-pressure Raymond mill pulverizers are only suitable for grinding fine ore powders of less than 400 mesh. Fine powders with higher fineness are due to their grinding rollers and grinding rings. Restrictions, as well as restrictions on electric power, etc., using this type of equipment for processing is not a good choice, and many of these equipment simply cannot do such a high degree of fineness.
How to choose suitable milling equipment for processing 400 mesh -1250 mesh ore micro powder in industry?
I recommend a CLIRIK ultra-fine stone powder making machine-HGM ultra-fine micro powder grinding mill. The ore materials processed by HGM ultrafine powder grinding mill include calcite, barite, limestone, pyrophyllite, dolomite, calcium carbonate, talcum powder, gypsum powder, Shale, potash feldspar, albite, mica, quartz stone, wollastonite, etc., can be processed as long as the hardness meets the processing requirements of the equipment.
The main advantage of HGM micro powder grinding mill in processing high-fineness mineral powder is that the fineness can be adjusted freely, the fineness can be as high as 3000 mesh, and it can be freely adjusted between 300-3000 mesh. Therefore, the fineness requirement of 400 mesh-1250 mesh is only the middle value of the equipment adjustable fineness for the ultrafine mill, so it is a very good choice to use this kind of equipment to process 400 mesh-1250 mesh ultrafine ore powder .
The structure of HGM micro grinding mill
The main part of the ultra-fine mill is composed of the main engine, reducer, analysis machine, fan, bypass powder collector, maintenance platform and electric control cabinet. The auxiliary machine part is composed of jaw crusher, bucket elevator, electromagnetic vibrating feeder, storage bin, etc.
When working, the main motor drives the main shaft and the turntable to rotate through the reducer, and the roller pins on the edge of the turntable drive dozens of grinding rollers to roll in the grinding ring raceway.
The large pieces of material are crushed into small particles by the hammer crusher and then sent to the storage bin by the elevator, and then through the vibrating feeder and the inclined feeding pipe, the materials are evenly sent to the bulk tray on the upper part of the turntable.
The material is scattered to the periphery of the circle under the action of centrifugal force, and falls into the raceway of the grinding ring, and is impacted, rolled, and ground by the ring roller. After three-layer ring processing, it becomes powder. The high-pressure fan removes the external air through suction. Inhale into the machine, and bring the crushed material into the powder concentrator.
The rotating impeller in the powder concentrator makes the coarse materials fall back and regrind. The fine powder that meets the requirements enters the cyclone powder collector with the airflow and is discharged by the discharge valve at the lower part of the cyclone as the finished product. The airflow with a small amount of fine dust passes through The pulse dust collector is discharged through a fan and a muffler.
What matters should be paid attention to when HGM ultra-fine mill is working?
1. Check the bearing temperature frequently. If the temperature is too high, check whether the lubrication and transmission parts are normal, and whether the rolling distance is too tight. Find out the cause in time, take corresponding measures, and stop the machine for inspection when the situation is serious.
2. Check the tightness of the transmission belt frequently. Too loose the belt will reduce the transmission efficiency and affect the grinding effect. If the belt is too tight, it will easily cause the bearing to heat up, increase power consumption and reduce the service life of the transmission belt.
3. Various transmission parts must be fastened and reliable, special tools should be used for disassembly or installation, and direct hitting with tools such as hand hammers is prohibited.
4. Do not forget to check the pneumatic components. After the plastic mill is turned on, always check the pneumatic components in the gas circuit, whether there is any leakage or damage in the gas circuit and the connection. At the same time, check whether the air supply pressure meets the requirements. The usage status of the battery should also be checked frequently. If it is found to be too tight, too loose, jumping, running deviation, severely worn, etc., it should be adjusted, repaired or replaced in time. The oil storage of the oil mist device in the air source triplet should be checked regularly, and 20# spindle oil must be added to prevent the small holes of the pipeline from being blocked.
In processing 400 mesh -1250 mesh micro ore powder, the micro powder grinding mill can be easily controlled, and the output is relatively large, and the service life of the grinding roller and grinding ring is long. If the customer's demand for output is not large, we recommend small-scale ultra-fine mill equipment. TheCLIRIK micro powder grinding mill adopts a sealed design in the overall design, and the link of the other supporting equipment of the entire production line adopts a seamless combination method, so that the ultra-fine ore powder can be processed by the equipment so that the powder is not leaked, and there is no dust pollution. No noise pollution, all indicators have reached national standards. At the same time, CLIRIK has multiple customer sites across the country, and the processed materials involve ore. Can provide customers with a convenient customer site, convenient for customers to visit the site.
