China (Mainland)
Ball mill is the key equipment of beneficiation equipment for grinding after the crushing
process, which is composed by feeding part, discharging part, turning
part and driving part (reducer, small driving gear, electric motor and electric control) and
widely used in the manufacture industries, such as cement, silicate,
refractory material, new building material, fertilizer, ferrous metal, nonferrous metal and
glass ceramics, moreover, according to different materials and discharging
methods, there are dry ball mills and wet ball mills for choice.
Working Principle of Ball Mill
According to different ways of discharge and overflow ball mill can be divided into lattice
type and overflow. This machine is grid type mill with two positions.
When the machine starts work, material from the feed device air shaft spiral evenly go
into first mill warehouse, the warehouse equipped with ladder liner or
corrugated liner, inbuilt are different size steel balls, centrifugal force produced by steel
rotating cylinder will brought the ball down after a certain height, severe
impact on the material and grinding them; After coarse grinding in the first mill warehouse,
then go into the second warehouse from single-compartment plate, the warehouse lined with flat liner, built-in ball, the material be further grinding; Powder material discharged through the discharge
grate plate , and meanwhile completed the grinding operation.
Features of Ball mill
1) Ball mill is an efficient tool for grinding many materials into fine powder.
2) The ball mill is used to grind many kinds of mine and other materials, or to select the mine.
3) Ball mill is widely used in building material, and chemical industry.
4) There are two ways of grinding: the dry way and the wet way.
5) Ball mill can be divided into tabular type and flowing type according to differentexpelling mine.
6) To use the ball mill, the material to be ground is loaded into the neoprene barrel that contains grinding media.
7) As the barrel rotates, the material is crushed between the individual pieces of grinding media that mix and crush the product into fine powder over a
period of several hours.
8) The longer the ball mill runs, the finer the powder will be.
9) Ultimate particle size depends entirely on how hard the material you¡¯re grinding is, and the time how long the ball mill runs.
10) Our ball mills have been used to grind glass, powder food products, create custom varnishes, make ceramic glaze, powder various chemicals.
The advantages of Ball Mill is as follows:
(1) adaptability is strong, for most materials can be grinding.
(2) can continuous operation, and production capacity can meet the need of modern industrial production on a large scale.
(3) crushing than the big, in the ordinary circumstances, above 300, mill circumstances can reach more than 1000. And fineness and product graded easy to adjust
(4) can adapt to the different conditions in the operation, and reliable operation. For example, crushing and dry crushing and mixed simultaneously; Can be used
either for dry shattered, and can be used in wet shattered; Can closed-circuit grinding, and can open grinding, etc.
(5) single cylinder structure, mechanical reliability, wear parts easy to check and replacement.
(6) the craft is mature, can be standardized.
(7) have a good sealing, can the negative pressure operation, so as to avoid dust flying, improve working conditions, and to prevent the air and environmental pollution.
In view of the advantages of ball mill, it is suitable for dry grinding, wet grinding, crushing various hard, dry in hard minerals, such as black metal, non-ferrous metal, limestone, cement, iron, coal, chemical raw materials and all kinds of metal solid materials.
