CLUM Ultrafine Powder Vertical Roller Grinding Mill

CLUM Series Ultrafine Vertical Roller Mill plant can be widely used in such industries as non-metallic mining, chemical and metallurgy. In particular, it is outstanding in the pulverization of white untra-metallic ore. It is capable of providing high quality fillers and additives used in the segments of plastic, rubber, paper-making, PVC, printing ink, coating and pigment industry.

Working principle of CLUM series ultra fine vertical roller grinding mill

The grinding plate is rotated by the main motor via the reducer. Meanwhile, air enters the mill interior via the air inlet. The screw conveyor is responsible for conveying materials. Materials then fall into the center of the grinding plate in rotation. Due to the centrifugal force, the materials evenly move from the center of the grinding plate towards its fringe. While passing across the track in the grinding plate, large blocks of materials are crushed and ground directly by the grinding roller. The fine particles form on the material bed, owing to squeezing, where the inter-particle crushing takes place.

The crushed materials continue to move towards the fringe of the grinding plate until they are taken away by strong air flow at the air ring. Coarse materials will fall on the plate and be ground again.

While the materials along with the air flow pass through the separator located above the grinding plate, the coarse particles return to the grinding plate for re-grind due to the action of the rotor blade; the fine particles along with the air flow will be taken away, collected and discharged as finished product by the powder collector.

Under the centrifugal force, few big particles were thrown out the grinding plate, and fall into the lower grinding chamber, and then is scraped into the slag outlet to be discharged by the scraping plate installed at the bottom of grinding plate.

Rotation speed of classifier impeller is easy to adjust to achieve different size of qualified powder products.

Construction of CLUM Series Ultrafine Powder Vertical Roller Grinding Mill

CLUM Series Ultrafine Vertical Roller Mill mainly consists of the motor, reducer,grinding rollers, grinding plate, pressure-applying device, classifier, mill body, oil station and electric control system.

Grinding roller: main component used for crushing and grinding materials. Together with the liner plate on the grinding plate, it can provide an effective grinding area.

Grinding plate: Component fixed on the output shaft of the reducer and where the grinding rollers grind materials.

Pressure-applying device: Component used for applying sufficient pressure to the grinding rollers to grind materials.

Classifier: A highly efficient and energy saving powder separation device which has the function of separate qualified finished powders and coarse powders.

Main Powder Production Process of the System

The system process include raw material washing, primary crushing, iron separation, secondary crushing, raw materials storage, weighing, iron removing, medicine filling, ultrafine powders grinding, main unit classifying, pipe conveying, pulse bag filter powders collection, finished powders transporation, packaging, compressed air transporation system, power remote control system and PLC central control system etc.

Processing Materials of CLUM Series Ultrafine Vertical Roller Mill

CLUM Series Ultrafine Vertical Roller Mill is a kind of equipment for processing ultra - fine powder and superfine powder, it is mainly used in medium and low hardness, hardness is lower than 6, non-flammable and non-explosive materials. It is widely used in calcium carbonate, marble, limestone, talc, barite, brucite, wollastonite, pyrophyllite, dolomite, kaolin, lime etc.

CLUM Series Ultra Fine Vertical Roller Grinding Mill VS Ball Mill

Comparison of ultrafine vertical mill & ball mill
Item	Ultrafine Vertical Mill	Ball Mill
Power Consumption	Lower power consumption by 30-50%: varies from material abradibility and powder particle size.	High power consumption
Product flexibility	Product catagory is adjustable flexiable: avaiable for production the powders with specific surface area range 9,500 (d97=20μm) to 25,000(d97 =10μm)cm2/g.	The different sizes of balls in the ball mill are fixed, only make one single product
Drying Power	Higher drying power: New type roller mill, available for larger air volume, which capable of higher moisture raw material	Due to limited air volume goes thourgh ball mill, extra drying system should be installed for ball mill system.
Equipment Space Required	Small, only 50-70% comparble with ball mill system.	Large space required.
Input Particle Size	larger size input size available: The input size is refer to the diameter of rollers, larger size raw material available, no need overcrushed.	Smaller size of raw material,the size is subject to maximum diameter of steel balls in it.
Finished Powder Size	Better end products, the mill has higher and adjustable grinidng pressure, which comes out bulk ultra fine powders.	lower percentage of ultra fine powders for ball mill
Size Distribution	Most advanced horizontal type air classifier installed on the top of mill which ensure wide range of end products	Old type classifier, steeper particle size distribution
Time of Changing Different Products	Short time to transfer different size powder product with one mill plant	Long time for cleaning the system for changing diferent size product.
Finish Products Contamination	Higher whiteness, no any grinding parts abrasion	Low whiteness, due to abrasion of grinding balls
Grinding Efficiency	High efficiency, lower abrasion	Lower efficiency
Initial Investment Cost	A little higher than ball mill sytem	Lower than vertical mill
Running Cost	Low, no grinding media and lower power consumption	High, due to grinding media and lower power consumption
Noise	Low	High
Product Whiteness	High	Low
Product Shape Sophericity	Not very good	good
To be effected by external factors	Sensitive to metal impurities	Insensitivity
