What happens when the ore particle size increases or the ore hardness increases? How to adjust?

Sudden occurrence of such a phenomenon is often caused by a failure of the crushing system screening equipment or a leak at the bottom of the screen, resulting in an increase in particle size. The hardness of the ore changes, which may be caused by different ore mining. In both cases, the grinding process will cause a corresponding change. First, the size of the ore discharge becomes coarser, and the second is the increase in the amount of sand returned.

The method of adjustment is to increase the concentration of ore discharge and increase the overflow concentration of the classifier to reduce the amount of sand return. If the fineness cannot be solved, the amount of ore can be appropriately reduced to deal with.

The air-to-air cooler is mainly used in various air, high-humidity air, mixed gas of various media, etc., and the air cooling method is adopted to cool the high-temperature air passing through the heat exchanger.

Advantages: Strong corrosion resistance, compact structure, small footprint, and high degree of customization.various air-cooled drive modes, DC motor, AC motor, hydraulic motor, air motor, special explosion-proof motor, etc., better to choose the appropriate drive mode according to industrial environmental factors, without the help of external cooling medium, lower The hardware requirements can be used to cool the oil and ultimately ensure the benign operation of the equipment.

Applications:Construction machinery engines, automotive engines, air compressors, industrial spray equipment, new energy equipment, electrical equipment, marine equipment, wind power equipment, etc.
