Good Design Dry Ball Mill Suit For Rock/Stone/Cement  

Dry ball mill Introduction:

     Dry Ball mill is the key equipment for secondary grinding after crushing. And it is suitable for grinding all kinds of ores and other materials, no matter wet grinding or dry grinding. Besides, it is mainly applied in many industries, such as ferrous&non-ferrous metal mine, building materials, chemical, electric power, coal, traffic, light industry, etc.

    In our company, this series of high-efficiency ball mill adopts rolling bearing support instead of sliding bearing support with bearing bush. Therefore, it can save energy by 10-20%. According to different discharging ways, it can be divided into two kinds, grate type and overflow type.

Structural characteristics of Dry ball mill :

    This dry ball mill is made up of feeder part ,discharging part ,rotating part ,transmission part(reducer,samll transmission gear ,motor,electric control) etc. main part.Hollow shaft adopt steel casting, lining can be converted,big rotating gear processed by casting gear hobbing .In the barrel there are board of wear-resistant,have a good characteriatics of wear-resisting.The machine is of steady operating and reliable working.

Working principle of Dry ball mill :

The dry ball mill has horizontal cylindric rotating device, outer rotating with gear, two warehouses, is lattice-type ball mill. Material from the feeder device throuth hollow shaft of feeder evenly into the first warehouse of dry ball mill , there are ladder liner and ripple liner in the warehouse , built by steel ball with different specifications , rotating cylinder produces centrifugal force take the ball to a certain height then fall,have a impact of the thumping and grinding for the material. After the material in the first warehouse reach coarse grinding,pass throuth single-wall partition into the second position, the warehouse lined with flat lining and steel balls in it ,have further grinding for the material . Powder discharged through the discharging plate to complete the grinding operation.
