How to Improve Fineness of Raymond Mill?

How to Improve Fineness of Raymond Mill?
The fineness of Raymond mill directly affects the quality of finished products, which will naturally be concerned by mill manufacturers. Therefore, Raymond mill manufacturers have increased their R&D efforts. How can we improve the particle size of finished products of Raymond mill?

Raymond mill is an important grinding equipment. It is mainly used for grinding metallurgy, building materials, chemical industry, mining and other mineral materials. It is mainly used for processing quartz, feldspar, porcelain clay, clay, bentonite, calcite, talc, barite, fluorite, clay, white mud, gypsum and other non-flammable and explosive mineral materials whose hardness is below Mohs 7 and humidity is below 6%.

Factors affecting fineness of finished products of Raymond mill:

1. The first factor is the size of the crushing particle of Raymond mill. If the feed size of grinder changes in production, it must be immediately reflected in the crushing workshop. The finer the crushing size, the better, because the size of the feed gravel determines whether the mill is empty and power consumption doubles.

2. Raymond mill hardness. Different ores have different hardness. In production, reasonable ore blending can be carried out to make the ore size uniform as far as possible and the proportion of massive and powdery ore reasonable and stable. Non-uniform ore feeding will lead to unstable production and idle operation of ore feeding equipment; more ore feeding, easy to plug.

3. Wear of Raymond mill. After the parts of Raymond mill are worn out, the amount of sand returned decreases, resulting in the coarsening of grinding fineness. In addition, if the wear is severe, it will affect the service life of Raymond mill, so in the work of timely inspection of wear, timely replacement of vulnerable parts.

4. The influence of air volume of Raymond mill. The larger the air volume, the coarser the grain size; the smaller the air volume, the finer the grain size. In production, the air volume in Raymond mill can be controlled to change the particle size of finished products.

In addition to the above factors, there are also some factors that may affect the product fineness of Raymond mill, such as the size of ore feeding, the type of Raymond mill, the number of steel balls, the proportion of steel balls, the speed of Raymond mill, the liner wear of Raymond mill, the size of the discharge port of Raymond mill and so on. These factors will have a certain impact on the fineness of the finished product of Raymond mill, which should be paid attention to in the design.
