Dry Ball Mill

[Introduction]: Dry ball mill is a grinding equipment used to deal with dry materials.

[Capacity]: 0.25-100t/h

[Improvement]: Xinhai dry ball mill is a grid type and horizontal cylindrical rotating device with two bins. This dry grinding machine has the outer gear transmission.

Advantages

01

Strong adaptability to the material, continuous production, and easy to adjust the fineness of grinding product;

02

Straight cylinder designed at the discharge port, the dry ball mill is equipped with the air-inducing device, which has a good dedusting effect;

03

It can be used for open-flow grinding or circulating grinding consisting of a powder separator;

04

Overflow dry ball mill and grid dry ball mill can be selected according to the ore property and discharge way;

05

The output material of dry ball mill after the dry grinding is the qualified material;

06

Dry ball mill can be divided into levorotary type dry ball mill and dextral type dry ball mill according to the grinding process;

07

Simple structure, easy to maintain; the hollow shaft of dry ball mill adopts steel casting, which makes the linear replacement easier;

08

Note: The feed water of dry ball mill should not be too high, otherwise the material is easy to bond, thus resulting in the difficulty of ore discharge.

Product Structure

The materials are uniformly sent to the first chamber of the dry ball mill by the feeding device through the feeding hollow shaft. The first chamber of the dry ball mill contains stepped lining board or corrugated lining board, and steel balls of different specifications. The centrifugal force generated by the cylinder rotation will bring the steel balls to a certain height and then drop down, which will have a pounding and grinding effect on the materials. After the rough grinding is finished in the first chamber of the dry ball mill, the materials will enter into the second chamber through the single-wall partition, which is lined with the flat lining board and steel balls to further grind the materials. The powder material is discharged through discharge grates, then the grinding operation is completed.
