Dry Ball Mill

【Introduction】:
A grinding equipment used to deal with dry materials.
【 Capacity 】:
0.25-100t/h
【Improvement】:
Xinhai dry ball mill is horizontal type and tubular running device, which has two warehouses. This machine is grid type and its outside runs along gear.

【Advantages】

1. Strong adaptability to the material, continuous production, and easy to adjust the fineness of grinding product;
2. Straight tubular designed at the discharge port, equipped with air-inducing device, which has a good dedusting effect;
3. Dy ball mill can be used for one-pass grinding or close-circuit grinding that is composed of powder concentrator;
4. Overflow dry ball mill and grid dry ball mill can be selected according to the ore property and discharge way;
5. The output material after the dry grinding is the qualified material;
6. Dry ball mill can be divided into levorotary type and dextral type according to the grinding process;
7. Simple structure, easy to maintain; the hollow shaft adopts steel casting, which make the linear replacement easier.
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 dry ball mill by the feeding device through the feeding hollow shaft. The first chamber of 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 dry ball mill, the materials will enter into the second chamber through the single-wall partition, which is lined with 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.

【Successful case】

dryballmill3

A Gansu mineral processing plant wanted to choose a dry type ball mill manufacturer for its second construction plant. At the early stage, too high equipment failure rate seriously influenced the productivity of entire mineral processing plant. Through the friend introduction, the client knew Xinhai Mining, and bought two dry ball mills for the mineral processing plant. At present, the dry ball mill has been formally put into production without abnormalities, and the working efficiency of the dry ball mills was increased by 12%.
