High quality mining grinding ball mill for ore

Ball mill is widely used in mining, smelting,road,building material and chemical. It is the key equipment for grinding after the crush process.The mill consists of feeding device, driving assembly, rotating assembly,bearing unit,discharging assembly and foundation unit.There are two discharging type: wet grid ball mill and dry grid ball mill.

1. Feeder; 2. Feeding unit; 3. Discharging unit; 4. Cylinder; 5. Girth gear; 6.Rack; 7. Transmission Division; 8. Bearing Division

(1) Save energy: bush bearing is replaced by rolling bearing, friction resistance being greatly lowered down, easy to be started. It’s energy is lower 10-15% than the old one.

(2)Large capacity: for the outlet disk and the checked liner are adopted, the capacity is higher 20% than the cone ball mill.

(3)The discharging port slurry surface is low, slurry flow through rapidly, decrease ore over-grinding.

(4)Load of ball is large, big balls, small balls be loaded in, and small balls can’t be discharged, and can form good working conditions.

Usually used in the following similiar process of gold,silver,copper, lead zinc, molybdenum and so on.

Startup of ball mill

A. Check if all connecting bolts are tightened before startup of ball mill, and if there is any loosening with all connected parts.

B. Check if lubrication of oil site meet requirements.

C. Check if there is anything around ball mill and sorting machine, which may prevent the machines from running.

D. Startup sequence for devices of loop; start ball mill before sorting machine, followed by ore feeding after normal running.

Stop of grinding loop:

If grinding loop stops running, stop ore feeder first. Then stop ball mill after the ores are processed inside the drum of ball mill. Take out the screw axis of the sorting machine out of the sand surface. Stop the sorting machine finally

Provide ore dressing experiment,process design and onsite engineering service.
