Ball Mill

Equipment Introduction

Ball mill is an important equipment in the grinding process.It ismainly placed after the crushing equipment and is a key equipment for re-crushing coarse sand and gravel materials. It has the characteristics of high crushing ratio,good reliability,strong adaptability and large processing capacity. According to the different grinding media installed,it can bedivided into ball mill,rod mill and autogenous grinding machine without media.

Features

1. Save energy

2. Rolling bearings are used instead of traditional sliding bearings to improve starting conditions,reduce the starting torque of the mill and the current during normal operation.The energy consumption of the mill dunng nommal operation is 15 to 20%lower than that of a mill using traditional bearing bushes.

4. Flexible design of the dischargedepartment,the feeding part has a large amount offeed

5. The discharge port can be selected as either grid type or overflow

6. type according to process requirements.

7. The feed inlet is equipped with a feeding spiral to force feeding,

8. which increases the feeding amount.

10. Liner castings

11. The structure,shape and material of the cylinder lining plate,end lin-

12. ing plate,compartment plate and discharge grate plate have been

13. tested by long-term production practice.

15. Use a closed system to reduce dust

16. The ultra-fine ball mill and classifier form a closed system,with neg-

17. ative pressure transportation and small dust,reducing hamm to the

18. human body.

20. Optimization of cylinder structure

21. Lining plates and grinding bodies can be made of alumina ceramics,

22. quartz,SILEX or special materials,and hard minerals are designed

23. to be free of iron pollution.

25. Dry oil spray lubrication

26. Large and small gears are lubricated with dry oil spray lubrication,

27. which has unifomm and reliable lubrication,high energy efficiency,

28. low fuel consumption,small footprint,no oil leakage,and no envi-

29. ronmental pollution.

Ball Mill Working Principle

The material is fed into the mill by a drum feeder through a spiral cylinder with a hollow shaft. The grinding medium is installed in the barrel body. When the barrel body rotates, the grinding medium is attached to the wall liner surface of the barrel body due to the inertial centrifugal force. After being rotated together with the barrel body and brought to a certain height, the materials in the barrel body are broken by gravity.

In addition to the cyclic movement of ascending and falling, the grinding medium also causes sliding and rolling in the rotating cylinder body, causing grinding action between the grinding medium, the lining plate and the material to grind the material.
