grinding ball mill: 1.for cement,silicate,ceramic 2.Mn linning,durable 3.dry and wet grinding types 4.special design

grinding ball mill:

1)  to grind various of mine materials and other materials;2)  two ways of grinding: dry-type grinding and wet-type grinding;3)  good wear resistance with wear-resistance liner plates;4)  reducing energy cost by 30%, with double rows of aligning spherical roller bearing;5)  high-grade steel welding, reliable work condition;6)  fine grinding, capacity rising by 15-20% compared with traditional ball mill;7)  finished particle size depends on hardness of materials and the time of ball mill runs;8)  also used to grind glass, food, chemicals, make ceramic glaze.

Coal grinding ball mill is a key equipment to grind all kinds of ores and other materials.which is widely used in powder-making production line including cement, silicate, new-type building material, refractory material, fertilizer, ore dressing of ferrous metal and non-ferrous metal, glass ceramics, etc.

grinding ball mill mainly consists of feeding part, discharging part, gyre part, transmission part (decelerated machine, small transmission gear, motor, electric control) and so on. The quill shaft adopts cast steel part and the liner is detachable. The turning gearwheel adopts casting hobbing process and the drum is equipped with wear-resistant liner, which has good wear-resistance. The machine is with stable and reliable working condition. Moreover, according to different materials and discharging methods, there are dry ball mills and wet ball mills for choice

 Coal grinding ball mill working principle:

Ball Mill is a horizontal rotating device transmitted by the outer gear. The materials are transferred to the grinding chamber through the quill shaft uniformly. There are ladder liner and ripple liner and different specifications of steel balls in the chamber. The centrifugal force caused by rotation of barrel brings the steel balls to a certain height and impact and grind the materials. The ground materials are discharged through the discharging board thus the grinding process is finished.
