Working principles and applications

As an outstanding machine to produce super fine powder, SBM SCM ultrafine mill is widely used to process various minerals that feature breakable, non-flammable, non-explosive and with Mohs’ hardness lower than 7, such as calcite, limestone, kaolin, and gypsum etc. In addition, some harder materials can also be ground by this mill, but the output, end products fineness and lifetime of wearing parts of the machine may be different with that of normal materials.

Ultrafine mill machine unique process features:

1, the choice of large rotor-type ultrafine mill of the analyzer, strictly control the large particles into the product. The selected coarse particles are returned to the pulverized area by itself. So that ultrafine mill system can be directly from the block material to produce 800 mesh powder.

2, to improve the existing large cyclone dust collector, improve the ability to capture the product.

3, the abolition of the original small cyclone dust collector, with a bag filter instead, to improve the ability to capture the fine powder to reduce the pollution of the surrounding environment while reducing the internal heat of the mill gathering.

4. Improve the grinding part of ultrafine mill, improve the grinding capacity of fine powder, reduce vibration.

SCM Ultrafine Mill Structure

Ultrafine mill applications

Ultrafine mill machine is one of the important equipment for deep processing of nonmetallic ore. It is suitable for barite hardness of barite, calcite, potassium feldspar, talc, marble, limestone, ceramics and glass. Of non-flammable and explosive mining, chemical, building materials, metallurgical and other industries more than 280 kinds of materials, milling processing, finished product size in the 100-325 mesh range of arbitrary regulation. Because the stability of production has been widely used.

Ultrafine mill of the work process

Ultrafine mill is a horizontal rotary cylinder. The cylinder is divided into three to four positions by the partition plate, and the appropriate grinding body is filled in each bin. When the ultrafine mill rotation, the grinding of the grinding body due to the role of centrifugal force attached to the inner wall with a rotation, was brought to a certain height, due to the role of gravity from the inner wall of the shot, the grinding of the material crushed. In addition, the ultrafine mill in the grinding body when there are rolling and sliding phenomenon, the material plays a rubbing grinding effect. The effect of grinding and grinding of the material can be seen, when the grinding of the grinding body size larger, less loading, and the cylinder speed is faster, the centrifugal force generated, the grinding body was brought high, The distance increases, and thus the ability to crush the material strong. As if people in the hands of a heavier hammer, held a higher, down the power of the big reason similar. In this case, the sliding phenomenon of the polishing body is small, so that the grinding of the material is reduced. If the grinding inside the more people and small and small, distributed in the simplified section close to the center of the grinding body, in the ultrafine mill rotation, followed by the slow rise of rotation, resulting in centrifugal force is small, can not be To bring the appropriate height of the drop, rolling and sliding phenomenon increased, the role of the material to enhance the grinding. Therefore, the grinding material in the grinding of the larger and harder, the need for greater impact, should be in the mill to increase the diameter of the ball, so that the average diameter of grinding off, if the grinding particle size is small, fragile material , Can be loaded with a smaller average diameter and more grinding body. It can be seen, the grinding body loading, size of the size, a direct impact on the performance of ultrafine mill work.
