Bentonite Milling to 80mesh: Milling Equipment and Application in Drilling Fluid
Bentonite is a kind of clay mineral with montmorillonite as the main component. It has excellent properties such as water absorption, swelling, thixotropy and adsorption. It is widely used in drilling fluid, foundry, cat litter, agriculture and other fields. 80mesh bentonite powder is a common specification, which is mainly used in the preparation of drilling fluid. The quality of 80mesh bentonite powder directly affects the performance of drilling fluid, so the selection of appropriate milling equipment is crucial.
When selecting milling equipment for bentonite to 80mesh, the characteristics of bentonite should be considered. Bentonite has the characteristics of low hardness, strong water absorption and easy to agglomerate. Therefore, the milling equipment should have good drying and grinding effect, and avoid the agglomeration of bentonite during milling. At present, the commonly used equipment for bentonite milling to 80mesh includes Raymond mill, ball mill and air-swept mill.
Raymond mill is widely used in the production of 80mesh bentonite powder due to its simple structure, easy operation and low investment cost. The Raymond mill is equipped with a hot air system, which can dry the bentonite while milling, effectively controlling the moisture content of the product. When milling bentonite to 80mesh, the raw bentonite is first crushed to less than 25mm by a crusher, and then sent to the Raymond mill.
The material is ground by the grinding roller and grinding ring, and the hot air generated by the hot air stove carries the ground material to the classifier. The 80mesh qualified powder is collected by the cyclone collector, and the unqualified coarse powder falls back to the grinding chamber for regrinding. The Raymond mill has the advantages of stable product quality and good drying effect, but its production efficiency is low, and it is suitable for small and medium-sized enterprises.
