Raymond Mill Structure and Principles

Raymond Mill is suitable for the preparation of various mineral powders, preparation of pulverized coal, such as limestone, raw material ore, coal, and other materials. The internal structure includes host machine, analysis machine, pipe device, blower, finished cyclone separator, jaw crusher (optional), bucket elevator (optional), electromagnetic vibrating feeder (optional), electricity Control clicks, etc.
raymond mill mainly drives the main shaft, turntable and grinding roller through the reducer in the main motor to run the whole machine. The jaw crusher is used to crush the material to a small block and sent to the storage bin by the hoist. The material in the hopper is quantified, evenly and continuously conveyed to the host grinding chamber by the electromagnetic vibrating feeder. Outside air is sucked into the machine by suction and the crushed material is brought into the separator. Then, the powder is screened by a separator, and the materials that do not meet the standards are returned to the host grinding chamber for rolling. After the impact, rolling, grinding to achieve the purpose of milling. For the collection of conforming materials, non-conforming materials are reground. At the same time, good sealing effect and dust removal facilities make it give full play to its advantages to ensure product quality and production efficiency. Raymond Mill’s application industry is widely used in the processing of marble, limestone, fertilizer, coal, slag, glass and other non-metal materials. Due to the reasonable structure and stable performance of this equipment, it has a very high occupancy rate in the milling industry.

Three Reasons for Wear of Ultrafine Powder Mills

The pulverizer is an indispensable mechanical equipment in the material grinding process and is widely used in mining, cement processing and limestone processing. The processing of chemicals and other materials, but in practical applications, the situation of wear of the ultrafine mill will seriously affect the service life of the equipment. What causes the abrasion of the milling machine? ,
Abrasive hardness is too high, abrasive hardness has a significant impact on the material wear rate. The extent of this effect is mainly based on the ratio of the hardness of the material H. and the hardness of the abrasive H., with the H./H. change, the material wears. The mechanism will change, and the size of the abrasive will also have a certain influence on the wear. When the abrasive is below a certain critical size, the volume wear wears up and the size of the branch increases sharply; when a critical dimension is exceeded, wear occurs. The amplitude of the increase is significantly reduced. The performance of the mill that affects the wear of the material is: elastic modulus, macro hardness and surface hardness, strength, plasticity and fracture toughness, etc. The resistance to rub of industrial pure metals is proportional to its elastic modulus. However, this relationship does not apply to heat-treated steel, although the heat treatment does not change the elastic modulus of the material, but it will greatly improve its wear resistance. In contrast, the relative wear resistance of industrial pure metals and different types of steel and its macroscopic hardness It is directly proportional to the relative abrasion resistance of the steel before and after heat treatment. Its unique macro-hardness is determined by its macro-hardness, but the slope of its wear resistance changes with its macro hardness. The wear resistance depends not only on the steel’s Hardness, and depending on the composition of the crucible, the steels of different compositions have the same hardness after heat treatment, but their wear resistance is different. This shows that there is no single value correspondence between the wear resistance of various steels and their macro hardness. relationship.
