Importance of Ball mill

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 ball mill, Ball mill must be operated in a closed system, with oversize ball mill material continuously being recirculated back into the ball mill to be reduced. Various classifiers, such as screens, spiral classifiers, cyclones and air classifiers are used for classifying the discharge from ball mill. Ball mill is an efficient tool for grinding many materials into fine powder. The 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 ball mill: the dry process ball mill and the wet process ball mill. Ball mill can be divided into tabular type and flowing type according to different forms of discharging material.

Output of ball mill

Output of ball mill is related to ball load and ball diameter. One ball mill ball should keep relatively proportion with another ball. General size of the ball mill tube diameter ranges from 25mm to 60mm. If the ball mill cylinder body is full of large diameter balls, this is good for crushing large ball mill material. But the ball mill gap between the balls is large, and the relatively surface area is small, ball mill have disadvantages to fine grinding. However, the output of the coal ball mill is negative because of too many balls and small impact force. At the same time, because of the relatively larger surface area of the ball, the ball will increase energy consumption.

Ball mill grinding for cement plant

There are two kinds of ball mills in accordance with the grinding approach: the dry ball mill and also the damp ball mill. It truly is the main cement grinding mill, and is applied in limestone powder grinding approach, coal grinding, and gypsum grinding and cement clinker grinding procedure.

Ball mill for limestone grinding: Ball mill function with each other using the limestone crusher device to crush and grind limestone into powder in cement plant. Ball mill for coal powder: In cement plant, ball mill is employed to grind coal into powder, and then these coal powder combine with other cement supplies to generate cement. Ball mill for gypsum grinding: In cement plant, ball mill can also be used to grind gypsum into powder as cement additive. Ball mill for clinker grinding: In cement grinding plant, ball mill can also be utilized as cement clinker grinding mill to grind cement clinker into powder to create cement.

In the course of cement production line, controlling the saturating ball mill turns into the important tache of raising the output and top quality of cement. This course of action consumes probably the most power in cement plant. You can find strict requirements about fitness of cement. So we really should pick out the proper milling device for this approach inside the cement creation line.
