Cement Ball Mill Plant

We are making and supplying of Cement Ball Mill Plant in Zhengzhou, Henan, China. Cement raw material ball mill plant for grinding grinds material by rotating a cylinder with steel grinding balls, causing the balls to fall back into the cylinder and onto the material to be ground. The rotation is usually between 4 to 20 revolutions per minute, depending upon the diameter of the mill. The larger the diameter, the slower the rotation. If the peripheral speed of the mill is too great, it begins to act like a centrifuge and the balls do not fall back, but stay on the perimeter of the mill. The point where the mill becomes a centrifuge is called the "Critical Speed", and ball mills usually operate at 65% to 75% of the critical speed.

Composition of cement raw material ball mill plant for grinding

Cement raw material ball mill plant for grinding is composed by the feeding device, discharging device, rotary device, driving device(including reduction gears,small transmission gear, electrical machine, electronic control) and some other main components. The hollow shaft is made by the use of steel castings, the liner is detachable, rotary gear is cast with hobbing, the internal of cylinder installing with wear liner, which has a good abrasion resistance. This kind cement grinding machinery is stable to operate and reliable to work.
