Bentonite is also called porphyry, soapstone or bentonite, the main mineral component is montmorillonite, bentonite some physical and chemical properties are determined by montmorillonite. Bentonite can swell into a paste when water is added, so in general, people have these properties of clay collectively referred to as bentonite. Bentonite is divided into activated white clay, natural bleaching clay, organic bentonite, bentonite ore and so on. Bentonite is generally white, light yellow, if the bentonite contains different amounts of iron, and light grey, light green, pink, maroon and other colours, bentonite has the properties of adsorption, expansion, slurry, viscosity and so on.

Application of bentonite

Bentonite is very widely used, first of all, bentonite can be used as waterproof materials, such as some bentonite waterproof blanket, bentonite waterproof board and its supporting materials. Because of the good physical and chemical properties of bentonite, so it is also widely used in decolorants, thixotropic agents, suspending agents, fillers, catalysts and so on, greatly promoting the development of various industrial sectors. In addition, bentonite is also used in agriculture, light industry and cosmetics, pharmaceuticals and other fields.

Bentonite grinding process

Natural bentonite to be milled to meet the production requirements, bentonite Raymond mill is to carry out the important machinery and equipment for bentonite milling process. Although China's bentonite production is relatively abundant, but if not effectively used, will cause a lot of waste. Red Star company produces bentonite Raymond mill processing out of the bentonite powder quality, fine powder, into the degree of very high. Bentonite Raymond mill in the work, the first bentonite through the hood side of the feed hopper into the machine, Raymond mill host plum blossom frame is equipped with a grinding roller device, the equipment in operation, the grinding roller device will rotate around the vertical axis, because it also has its own rotary motion, so the centrifugal effect will be generated in the rotation of the grinding rollers and the grinding ring of the role of the grinding and grinding between each other will be the role of the material to be milled.
