Application of ball mill
Corundum ball mill is generally used to grind material 1/4 inch and finer, down to the particle size of 20 to 75 microns. To achieve a reasonable efficiency with Corundum ball mill , they must be operated in a closed system, with oversize material continuously being recirculated back into the mill to be reduced. Various classifiers, such as screens, spiral classifiers, cyclones and air classifiers are used for classifying the discharge from Corundum ball mill . Corundum ball mill is an efficient tool for grinding many materials into fine powder. The Corundum ball mill is used to grind many kinds of mine and other materials, or to select the mine. It is widely used in building material, chemical industry, etc. There are two ways of grinding: the dry process and the wet process. It can be divided into tabular type and flowing type according to different forms of discharging material.
Features of Corundum ball mill
1) Corundum ball mill is an efficient tool for grinding many materials into fine powder;
2) The Corundum ball mill is used to grind many kinds of mine and other materials, or to select the mine;
3) Corundum 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) Corundum ball mill can be divided into tabular type and flowing type according to different expelling mine
6) To use the Corundum 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 Corundum 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 Corundum ball mill runs.
10) Our Corundum ball mill have been used to grind glass, powder food products, create custom varnishes, make ceramic glaze, powder various chemicals
Working principle of Corundum ball mill
1. Material feeding: After the materials are roughly crushed, they will be fed into the Corundum ball mill.
2. Impact grinding: when the milling chamber is rotating at high speed, grinding medium and grind-need materials, which are also rotating, will impact with each other; thus to achieve impact grinding for materials;
3. Classification: after the materials are crushed, they will be discharged into self-diffluent classifiers. And then the relatively coarse and fine powders will be separated. Qualified powders will be collected; and unqualified powders will be re-crushed.
Note: Cleaned gas will be discharged by induced draft fans.
Introduction of ball mill
The Corundum ball mill grind material by rotating a cylinder with steel grinding balls, causing the balls to fall back into
the cylinder and onto the material to be ground. The rotation is usually between 4 to 20 revolutions per minute, depending upon the diameter of the mill.
