1.Introduction

Ball mill is a kind of machine for discontinuous production. It is special equipment that is especially used for fine-grinded dry material. Customer can control production time according to the characteristics of raw material (grain size, hardness) to achieve the fineness required. With simple technology, large capacity, low investment and easy maintenance, our ball mill can make customer get ideal production with lower cost, which make this equipment is widely used in chemical, biological chemistry, ceramic, abrasive material, resin, paint and medicine as well as other industries.

2.  Drive mode and speed adjusting
All our ball mills are drive by gear. It has the advantages of stable drive, long trouble-free operation, low noise and high drive efficiency, especially no colored dots that effect quality.

Starting current of ball mill is large because of its huge size and heavy weight. Too quick rotation speed for material output can cause spill of powder easily and results in the loss of product and environment pollution. In order to solve the problems above, it is necessary to select suitable speed governing system.

We have two kinds of speed governing modes for choice:

1). Speed adjusting motor: power cabinet is simple and motor is complex.

2). Frequency convertor: power cabinet is larger and motor is simple.
