The problem that many milling companies struggle with when purchasing mill equipment is which type of machine to choose. In fact, it depends on many issues, such as which material to grind and which fineness to grind. Today we will talk about what industrial mills are available.

When customers choose milling equipment, the company's technical staff will recommend the corresponding milling equipment to the customer according to the material to be crushed and the expected output. For example, if some customers need rough processing of stones, they can choose the hammer crusher and jaw crusher produced by the company. Another example is that some customers not only have high output requirements, but also need to meet a certain standard for fineness of the powder. Then you can buy an ultra-fine mill. Of course, the model of the ultra-fine mill is also different. There are high-pressure suspension roller mills, Raymond mills, etc., these are all mining machinery products. The fineness of the mill is as high as 3000 mesh. Of course, customers can adjust the fineness range according to their own requirements. As for the output, the output of the ultra-fine mill ranges from 0.7-8t/h, which depends on the model of the mill. set. Industrial pulverizer equipment can greatly meet the needs of customers in terms of grinding fineness, output and product performance.

How To Adjust The Fineness And Output Of The Mill?

The mesh number of the mill is inversely proportional to the output. As long as the fineness requirements are high, the output will inevitably be low. This is because the high fineness requirement means that the speed of the analyzer part is accelerated, and the coarser materials cannot be passed through, and the grinding must be performed again. This lengthens the grinding time of the material inside the mill, that is to say, it takes a long time for the finished product to come out per unit time, so the amount is also reduced.

Diameter of the spacer ring: The size of the spacer ring determines the time that the particles stay in the crushing chamber. The larger the diameter of the spacer ring, the shorter the residence time of the particles, the larger the size of the crushed product, the higher the output, and vice versa;

Air volume: The air volume can be controlled by adjusting the butterfly valve at the outlet end of the mill. As the air volume increases, the particle size of the product increases, and vice versa;

Slag discharge volume: adjust the size of the slag discharge hole of the slag discharge device to control the slag discharge volume, which can improve product quality and purity;

The gap between the grading impeller and the spacer ring: the gap decreases, the product becomes thinner; the gap increases, the product becomes thicker.
