Dry ball mill
- Product Introduction: A ball mill equipment for processing dry materials.
- Capacity: 0.25-100t/h
- Applications: It is used in industries such as mineral processing, building materials, metallurgy and chemical industry, and most of the materials processed are metal ores.
- Product Improvements: The dry ball mill is a horizontal cylindrical rotating device with outer gear transmission, two chambers, and a lattice-type ball mill.
Advantages and Features
- 1. The dry ball mill has strong adaptability to materials, can produce continuously, and is easy to adjust the fineness of the grinding product
- 2. The discharge port adopts a straight cylindrical design and is equipped with an air induction device, which has a good dust removal effect
- 3. It can be used for open flow grinding or for grinding in a circulating circle composed of a powder separator
- 4. According to the material and discharge method, an overflow dry ball mill or a grid dry ball mill can be selected
- 5. The material produced after dry grinding is qualified material
- 6. It can be divided into left-hand and right-hand according to the process
- 7. The dry ball mill has a simple structure and is easy to maintain. The hollow shaft is made of steel castings, and the lining is more convenient to replace. Note: The moisture content of the feed material to the dry ball mill should not be too high, otherwise the material will easily stick, resulting in poor ore discharge.
Working Principle
The material enters the mill bin evenly and spirally from the feeding device through the feeding hollow shaft. There are stepped linings or corrugated linings in the bin, which contain steel balls of different specifications. The rotation of the barrel generates centrifugal force that brings the steel balls to a certain height and then falls, which produces a heavy impact and grinding effect on the materials. After the material reaches coarse grinding in the warehouse, it enters the warehouse through the single-layer partition board. The warehouse is equipped with a flat lining plate and contains steel balls for further grinding the material. The powdery material is discharged through the discharge grate plate to complete the grinding operation.

Case Study
A dressing plant in Gansu was re-established for the second time and wanted to choose a dry ball mill manufacturer again. In the early stage of building the plant, the equipment failure rate was too high, which seriously affected the productivity of the entire dressing plant. Later, through the introduction of an old friend, I got to know Huston. After some understanding, I purchased 2 dry ball mills from Huston and applied them to the dressing plant. They have been officially put into production. No abnormalities were found, and the work efficiency increased by 12% compared to expected.
