The cement ball mill machine is mainly consisted of feed device, main bearings, rotating parts, drive device, selling device, high-voltage start-up device and lubrication system.This machine is a skeleton pattern ball mill with horizontal cylindrical turning gear, driving by outer gear and two hoppers. The material goes to the first hopper after the spiraling by the quill shaft from the feeding equipment.Our high-efficiency and saving-energy ball mill adopts rolling bearing substituting for sliding bearing, which can save energy 10-20% compared with sliding bearing. Adopting oil grease in place of thin oil lubrication station, and large-type mill needs not to be equipped with high-and-low pressure lubrication station with high cost.

The shell rotates so as to generate electricity, and this force brings ball to a certain height and then balls drop down by gravity, the impact is the grinding force to the material. After the primary grinding, materials go into the second chamber through segregate screen. In the second chamber, there are flat liners and steel ball. After the secondary grinding, material is discharged from the discharging outlet. Then the whole grinding process ends.Lattice-type ball mill has lattice panels at the discharge end, with more volume of ball, larger installation power, higher capacity and more coarse discharge granularity and usually used in primary crushing.

The hopper has ladder sheathing or corrugated sheathing with steel balls inside, which will fall under the effect of centrifugal force by barrel turning to ram hard and grind material. After the kibbling in the first hopper, by monolayer partition panel, the material will enter the second hopper, which has plane scale board with steel ball inside to grind material. The powder material will be discharged from the grid plate to finish the grinding. The raw material is feeded into mill by feeding equipment. The hot wind enters into the mill by inlet end.

The products like ball mill manufacturer, conveyor belt produced by our company have best quality and reasonable price. Fote Machinery won”t disappoint you!
