What kind of grinding equipment should be used for the preparation of superfine powder?

fxy/ Release time : 2023-07-10

According to the different production needs, the manufacturer will have different considerations for the selection of powder making equipment, first of all, the manufacturer wants to process the material feed size how? What is the hardness of the material itself? What are the requirements for the discharge size of the finished product? How about the production capacity of the machinery and equipment? This series of common problems are affecting the manufacturer's consideration of machinery and equipment, only a suitable machinery and equipment to maximize profits, the most suitable for their actual production needs of the equipment is the best for themselves, then I take you to understand the production of a superfine powder grinding equipment.

Speaking of ultrafine powder grinding equipment, that has to mention the LUM ultrafine vertical mill, LUM series ultrafine vertical mill is a new type of ultrafine grinding equipment designed and developed by Liming Heavy Industry based on 30 years of experience in the development and manufacture of four generations of mills, based on LM vertical mill, the introduction of modern ultrafine vertical mill grinding roller technology, can be widely used in calcite, marble, limestone, heavy calcium, talc, barite, dolomite and other non-metallic minerals, It can be widely used in calcite, marble, limestone, heavy calcium, talc, barite, dolomite and other non-metallic minerals ultra-fine grinding processing, and is the ideal equipment for large-scale non-metallic mineral powder making plant.

LUM ultra-fine vertical mill has the following advantages:

1、The grinding curve of roller sleeve and liner plate specially designed to realize the principle of ultra-fine grinding, when used for ultra-fine powder grinding, it is easier to form the material layer than ordinary vertical mill, which makes the mill to grind to the required fineness at one time.

2、Adopting the principle of multi-head powder separator, and each rotor can be frequency-controlled, the fineness of the finished product can be achieved within the selected range, so that it can be graded without secondary wind selection, and there will be no downgraded material.

3、Pre-compaction device can ensure that the grinding part can "eat material" more effectively, so as to achieve a very fine grinding; ultra-fine vertical mill vibration is small, the power can be effectively played.

4、The grinding roller lubrication adopts a separate lubrication station, and the single grinding roller circuit adopts the mode of double pump pump and suction working at the same time, which not only makes the grinding roller bearing get sufficient lubrication and cooling, but also can ensure that the oil will not be stored in the grinding roller bearing chamber, which will lead to leakage.

5、The grinding roller pressurization control mode with PLC/DCS automatic control, the grinding pressure is accurately controlled, and no manual operation is required. It is also equipped with mechanical limiting device and electronic limiting device to prevent direct contact between the roller sleeve and the grinding disk liner, which avoids destructive shock and violent vibration.
