technical field

The utility model belongs to the technical field of design and manufacture of material crushing equipment, in particular to a shell water paint planetary ring gap grinding device.

Background technique

Ultrafine pulverization is achieved by means of impact, collision, shearing, grinding, and dispersion of materials. When choosing a crushing method, it must be determined by the physical properties of the crushed material and the required crushing ratio, especially the mechanical properties of the crushed material have a great decisive effect, and the hardness and fracture of the material are more important. For hard and brittle materials, impact is very effective; for tough materials, grinding and shearing methods are better. In fact, any kind of crushing machine is not simply a certain crushing method, generally two or more crushing methods are combined for crushing. For example, the jet mill is crushed by the mutual impact and collision of materials; the high-speed impact mill is crushed by impact and shear; the crushing mechanism of the stirring pulverizer and the ball mill is mainly grinding, impact and shear; The working process of the mill is mainly through the strong liquid flow shearing, friction, impact, etc. generated by the relative motion between the high-speed rotating abrasive body and the fixed abrasive body.

With the continuous development of ultrafine crushing technology, various devices suitable for ultrafine crushing have been developed and applied. In addition to ultra-fine grinding equipment based on grinding, such as ball (sand) mills, vibrating mills, and Raymond mills, various types of ultra-fine grinding equipment based on impact have developed rapidly in recent years.

At present, the main types of ultrafine grinding equipment at home and abroad are jet mill, mechanical impact ultrafine mill, stirring ball mill, vibrating ball mill, rotating cylinder ball mill, tower mill, cyclone self mill, centrifugal mill, high pressure jet mill Wait. Among them, jet mill, mechanical impact ultrafine mill, cyclone autogenous mill, etc. are dry ultrafine grinding equipment; The formula can also be used for wet ultrafine grinding.
