Working principle of overflow mill
Author:
The overflow mill is a kind of equipment commonly used in the field of ore crushing, and its working principle mainly involves two aspects: mechanical collision and hydraulic erosion. When the raw material enters the grinding chamber of the overflow mill through the feed port, the high-speed rotating grinding disc and grinding ring will strongly collide and grind the raw material. Under the action of this mechanical force, the raw material is gradually crushed and ground to the desired particle size.
At the same time, in the design of the overflow mill, it is also equipped with a water flow system. Water will be sprayed through the nozzle to form a water belt between the grinding disc and the grinding ring to scour and clean the raw materials, reduce wear and increase crushing efficiency. In addition, the water will take away some of the fine particles, to achieve classification. Through hydraulic washing and classification, the raw materials continuously circulate in the grinding chamber until the ideal crushing and classification effect is achieved.
In general, the overflow mill achieves efficient crushing and classification of raw materials through a combination of mechanical collision and hydraulic flushing. This equipment is suitable for ore, chemical raw materials, building materials and other fields, widely used in mining, metallurgy, cement and other industries.
