Raymond mill is used in a variety of industries, including mining and processing of minerals and materials in the metallurgy, industrial chemical industry, and others.
Here is a brief overview of how a Raymond mill works:
Feeding: Material is fed into the mill's grinding chamber. This is usually done through an automatic feeder, but manual feeding is also possible. The size of the material needs to be within the feeding size of the mill.
Grinding: Inside the grinding chamber, there are grinding rollers which are mounted on a hanging bracket. When the Raymond mill operates, the grinding roller starts to rotate around the central axis due to the centrifugal force. The grinding roller swings outward and presses against the grinding ring, creating a rolling pressure, which leads to the grinding of the material between the grinding roller and grinding ring.
Classification: The ground material is blown up by a blower and classified by an analyzer sitting above the grinding chamber. Depending on the speed of the analyzer, materials of certain fineness go through the analyzer, and coarse materials fall back for regrinding.
Collection: Fine particles are collected into the cyclone collector and then discharged from the discharging valve as final products. The air flow is returned to the blower through the return air pipe at the upper end of the large cyclone collector.
Recycling: The air flow with a small amount of fine dust passes through the pulse dust collector and is discharged through the fan and muffler.
Throughout this process, it's important to control the temperature to prevent overheating, which can affect the properties of the material being processed. The final particle size of the product can be adjusted by controlling the speed of the classifier.
