Ball Mill

The product particle size control is flexible, special design is adopted to reduce noise and emission. Automatic control, easy to operate. According to the scale of investment, it provides personalized customized scheme and provides value-added services.

It is widely used in calcium carbonate (calcite, marble, lime stone, chalk), quartz, zircon, paillite, barite, kaoline, dolomite, magnesite, alumina, super fine cement, slag, steel slag, etc.

Product features

  • The design is different from traditional cement mills and mining and metallurgical mills, and meets the requirements of German superfine filler grade mineral processing.
  • Optimize the aspect ratio to prevent excessive grinding and achieve optimum grinding results.
  • Optimize the opening ratio and opening design of the jaws, and increase the grinding fineness with a smaller grinding media.
  • The slab-type grinding tail discharges, the discharging is smooth, there is no grinding phenomenon, and the cylinder does not need to be cooled.
  • Grinding media according to product requirements, reasonable ratio, high filling rate, high efficiency.
  • Grinding aids when grinding ultrafine powders to improve grinding efficiency.
  • Optimize the matching of drive and grinding energy to maximize energy savings.
  • And the classifier forms a closed system, negative pressure conveying, no dust.
  • Optimize the shape and material of the lining and grinding media, according to German standards, reduce the damage rate and improve the grinding efficiency.

Working Principle

After coarse crushing, the material is fed into the ball mill through a controllable feeding device. The grinding medium in the mill repeatedly impacts and grinds the material by virtue of the kinetic energy obtained when the mill rotates. The crushed material is discharged into the suction tank through the tail of the ball mill, and then transported to the classifier for classification by negative pressure. The qualified fine powder is collected by cyclone collector or dust collector, The coarse particles after classification are discharged from the lower end of the classifier, and then re-enter the ball mill for crushing through the feeding pipe.
