Abstract

The invention relates to a powder material processing process. A proportion of the steel ball size of a common ball mill used now is improved, so that an impact force between the steel ball and processed large block materials is enhanced; a contact surface of the steel ball and the processed powder material is increased, thereby increasing grinding capacity. With the improvement of the proportion of the steel ball size, output of the ball mill is increased by about 10%; unit energy consumption is decreased by about 30% and unit steel ball abrasion is reduced by 50%, so that the disadvantages of large loading capacity, large unit energy consumption and large steel ball abrasion of a conventional ball mill are broken.

Description

The steel ball matching technique of ball mill
Technical field
The present invention relates to a kind of powder material processing technology, be specially adapted to the proportioning process of the steel ball of ball mill.
Background technology
Ball mill is after material is broken, carry out the key equipment pulverized again, it is widely used in the production industries such as coal-burning power plant, cement, silicate industry, New Building Materials, refractory material, chemical fertilizer, non-ferrous metal ore and glass ceramics, can be divided into dry type and wet type grinding to various ore and other grindability materials.
Current domestic ball mill has the shortcomings such as useful load is large, and unit power consumption is high, and unit steel ball abrasion are high, and main cause is that abrasive media steel ball size specification proportioning and total useful load are unreasonable, abrasive media impact and grainding capacity proportioning unreasonable.When preparing powder, the exerting oneself of qualified powder fails to reach maximum causes unit power consumption to rise; Steel ball material is selected unreasonable, and particularly case hardness and core hardness difference are greatly, and after causing ball mill to run a period of time, unit steel ball abrasion are high, steel ball consumption large, particularly produces highly purified powder and pollutes, affect product quality.
Summary of the invention
For described situation above, the object of the present invention is to provide and a kind ofly reduce steel ball just useful load, improve ball mill and exert oneself, reduce the steel ball matching method of the ball mill that unit power consumption and unit steel ball wear away.
In order to achieve the above object, steel ball matching technical matters of the present invention is characterised in that the steel ball percentage by weight of different size is.
