What is ultrafine grinding mill?

The ultrafine grinding mill is a high-quality professional equipment used for the production of limestone, calcite, diatomaceous earth, pyrophyllite, slag and other non-metallic mineral powders.
 

Consist of ultrafine grinding mill:

Ultrafine grinding mill mainly consist of main unit, classifier, powder collector, dust cleaner, blower, muffler, sound-proof room, crusher, bucket elevator, storage hopper, and vibrating feeder.
It can adjust product fineness according to each customer’s specific production requirements, to form a variety of capacity demand, meet the needs of different industries pulverizing demand, is high reliability and quality equipment which is high grinding efficiency and convenient maintenance.




How does ultrafine grinding mill work?

The large material becomes smaller after crushing by hammer crusher, and is sent to the bin by hoist, and then evenly sent to the upper distribution plate of flap by vibrating feeder and inclined feed pipe.
When the ultrafine grinding mill works, all the grinding rollers roll in the ring, and the materials are driven to the edge of the turntable by centrifugal force and fall into the grinding chamber, where the materials are repeatedly squeezed, crushed and ground by the rollers.
The high-pressure fan continuously inhales air, and the air flow of crushed materials enters the classifier. The high-speed impeller of the classifier screens the air flow: the unqualified particle size falls down, returns to the mill for regrinding, and the qualified particle size enters the cyclone collector after mixing with the air. Most of the qualified powder will fall and flow from the exhaust valve at the bottom; a small amount of fine powder will move to the dust collector with the air flow and attach to the surface of the filter bag. At the same time, because the high pressure gas controlled by the pulse valve ejects instantaneously, the sudden vibration of the filter bag causes the fine powder attached to the surface to fall. The above two batches of material are sent by the bottom conveyor to package the finished powder.
In addition, the filtered clean air is finally discharged from the outlet of the muffler.

Advantages of ultrafine grinding mill:

●High Efficiency
Under the same final particle size and the same motor power, the production capacity of the ultrafine grinding mill is twice that of the air flow mill, the mixing mill and the ball mill, and the energy consumption is reduced by 30%. The output is 40% higher than other mills.
●Long lifecycle of spare parts
High utilization rate of Wear material: 2-5years.
●High safety and reliability
The design of the mill is very strict, so there is no screw loosening to damage the machine.    
●High fineness & flexible adjustment
The final fineness of the grinding materials can be adjusted between 325 meshes and 3000 mesh.
●Environment-friendly
Closed system, so it is the green and ideal equipment for environment protection.

Application of ultrafine grinding mill:

Widely used in small and medium-sized mining, chemical, building materials, metallurgy, refractory materials, pharmaceuticals, cement and other industries.
Ultrafine grinding mill can be used to grinding barite, quartz, feldspar, mica, calcite, talc, apatite, gypsum, fluorite, limestone, dolomite, diatomite, pottery clay, clay, marble, granite, fly ash, kaolin, calcium carbonate, slag, bauxite, glass, etc.
