MQY Overflowing Type Ball Mill

The ball mill is a kind of equipment to grind ores and other materials with powder to obtain desirable granularity of product. The ball mill designed and manufactured by our company has been widely applied in such industries as metallurgy, mining, Building materials and chemical industry home and abroad.

The ball mill is mainly composed of feeding, charging, main bearing, barrel transmission, discharging parts and main motor. The barrel of grinder is driven by the motor through transmission and deceleration of gear pair to rotate in appropriate rotary Speed. The medium for ore grinding is lifted to a definite height under grinding stripping action due to rolling or sliding of Medium, the materials are discharged through discharge hole after being ground.

Description

Ball mill can divide into 2 types, wet ball mill and dry ball mill. Ball mill is a mineral processing machine for milling the materials into powders after they are crushed. It is widely applied to the production of cements, silicate products, building materials, fireproof materials, fertilizers, glass, ceramics as well as nonferrous and ferrous metal processing industries.

Features

1. Ball Mill use Allis Chalmers design;
2. Jack-up device, easy maintenance;
3. The hydrostatic and hydrodynamic bearings ensure the smooth operation;
4. Low speed transmission is easy for starting and maintenance;
5. The oil-mist lubrication device guarantees reliable performance of bearings;
6. The gas clutch adopts the flexible start-up model.

Application

1.Energy-Saving Ball Mill are generally used to grind material 1/4 inch and finer, down to the particle size of 20 to 75 microns.
2.To achieve a reasonable efficiency with ball mills, they must be operated in a closed system, with oversize material continuously being recirculated back into the mill to be reduced.
3.Various classifiers, such as screens, spiral classifiers, cyclones and air classifiers are used for classifying the discharge from ball mills.
4.Ball mill is an efficient tool for grinding many materials into fine powder.
5.The ball mill is used to grind many kinds of mine and other materials, or to select the mine.
6.Ball mill is widely used in mining industry, chemical industry, etc.
7.There are two ways of grinding: the dry process and the wet process.
8.It can be divided into tabular type and flowing type according to different forms of discharging material.

Working Principle

1.The Energy-Saving Ball Mill is a horizontal rotating device transmitted by the outer gear.

2.The materials are transferred to the grinding chamber from ball mill through the quill shaft uniformly.

3.There are ladder liner and ripple liner and different specifications of steel balls in the chamber.

4.The centrifugal force caused by rotation of barrel brings the steel balls to a certain height and impact and grind the materials.

5.The ground materials are discharged through the discharging board thus the grinding process is finished.
