According to the ultrafine equipment processing technology that our company grasps for years, the problems above have got a comprehensive technical renovation. When using traditional Raymond mills, we find that during processing calcite mineral, 325 mesh mineral powders contains lots of 10um ultrafine powder. If they are separated and expanded production, benefits will get increased remarkably. Therefore, we have a lot of innovation for the structure of Raymond mills.
Hongxing Raymond mill is widely used in ultrafine powder processing of barite, calcite, potassium feldspar, talc, marble, limestone, dolomite, fluorite, lime, activated clay, activated carbon, bentonite, kaolin, cement, phosphate rock, gypsum, glass, heat insulator and other non-flammable and non-explosive materials that Mok's hardness is not more than 9.3 and humidity below 6%. The size of type R Raymond mill can be regulated within 80-325, and part of the material can be as high as 600.
1, mechanical linkage theory from the microscopic point of view, any surface is rough,porous, bonding time limit.
2. Theory of physical adsorption of various bonding agents infiltrated into the hole of the object play a mechanical fixation.Physical adsorption between the molecules of any substance, although this force is weak, but because of the number of molecules, the total adhesive force is strong. When the material molecule then survived close ribs, more fully, the greater the force of physical adsorption. But this theory can not explain some of the non-polar polymers such as poly isobutylene and natural rubber between the strong adhesion phenomena.
3. Diffusion theory of adhesive molecules into a chain-like structure in constant movement. Posts connected twist then the agent molecules to pass through the movement into the surface of the object to be glued. At the same time, the sticky objects molecules also enter into the adhesive. This mutual penetration, diffusion, and the formation of strong bond between the adhesive and stick objects.
4. By chemical reaction between the adhesive to be glued to the surface of the chemical bond theory, the formation of chemical control, resulting in a close chemical combination as chains. When the bonding of the epoxy, phenolic resin and metal aluminum surface, there is chemical formation of silly.
In fact, drilling between the adhesive and bonding objects together by mechanical linkage, physical adsorption, the diffusion of the results with the chemical bond forms the combined effects of intermolecular 

With its high quality products such as China vibrating feeder, Sand maker, Combination crusher, Hammer crusher, Ore beneficiation, Henan Hongxing mining machinery Co.Ltd has ascended in the front rank of the world in the exporting of mining equipments.
