Bentonite mill introduction

快频彩票kpcpThe bentonite mill is a kind of Raymond mill, which is mainly developed for the physical properties of bentonite. The whole machine structure is composed of main engine, analysis machine, pipeline device and air blower. It can be equipped with crusher, hoist, electromagnetic vibrating feeder and electric control motor according to user needs. After the material is pulverized to the required particle size, the material is sent to the storage hopper by the hoist, and then the material is uniformly and continuously fed into the Raymond mill main grinding chamber through the vibrating feeder, and the grinding roller swings outward due to the centrifugal force during the rotation. Pressing on the grinding ring, the blade shovels the material and sends it between the grinding roller and the grinding ring, which is crushed by the rolling of the grinding roller. The fine powder after grinding of the material is brought into the analysis machine for sorting with the circulating wind of the blower, and the finely coarse material falls back to the regrind, and the qualified fine powder enters the finished cyclone powder collector with the airflow, and is discharged through the powder discharging tube. It is the finished product.

SBM's new large bentonite mill is a set of equipment designed to adapt to the development of large, green and intelligent equipment. It has already signed several contracts with many countries such as Vietnam, India, Malaysia, etc., and the company is still working on the R&D and production of mine machinery products, Raymond machines, and the new products from generation to generation are competing, and are also in line with international standards, achieving long-term and pleasant cooperation. relationship!

Introduction to bentonite

Bentonite is a non-metallic mineral with montmorillonite as the main mineral component. The montmorillonite structure is a 2:1 crystal structure composed of two siloxane tetrahedrons sandwiched by an aluminum octahedron, due to the formation of montmorillonite crystal cells. The layered structure has certain cations such as Cu, Mg, Na, K, etc., and these cations have a weak effect on the montmorillonite unit cell and are easily exchanged by other cations, so that they have good ion exchange properties. Foreign countries have been applied in more than 100 departments in the 24 fields of industrial and agricultural production, with more than 300 products.

快频彩票kpcpBentonite is also called porphyry, bentonite or bentonite. China has a long history of developing bentonite, which was originally used as a detergent. (Sichuan’s Renshou area has open pit mines hundreds of years ago, and locals call bentonite a soil powder). It is really widely used but only a hundred years old. The United States *** was discovered early in the ancient strata of Wyoming, a yellow-green clay that can be expanded into a paste after adding water.

Later, people called clay with this nature collectively called bentonite. In fact, the main mineral component of bentonite is montmorillonite, the content is 85-90%, and some properties of bentonite are also determined by montmorillonite. Montmorillonite can be in various colors such as yellow-green, yellow-white, gray, white, and the like. It can be made into a dense block or a loose soil. It has a slippery feel when rubbed with a finger. The volume of the small block is several times to 20-30 times when it is added with water. It is suspended in water and is mushy when there is little water.

Bentonite application

The nature of montmorillonite and the type of exchangeable cations between the layers are highly dependent. According to the type of the main exchangeable cation between the layers, montmorillonite is usually classified into calcium montmorillonite and sodium montmorillonite.

Montmorillonite has adsorptive and cation exchange properties, can be used to remove oil toxins, gasoline and kerosene purification, wastewater treatment; due to good water swelling properties and dispersion and suspension and pulpability, it is used in drilling mud, Flame retardant (suspended fire extinguishing); can also be used as filler in the paper industry to optimize coating properties such as adhesion, hiding power, water resistance, scrub resistance, etc.; because of good adhesion, it can be used instead of starch. The yarn sizing in the textile industry is both grain-saving and hairless, and it does not emit odor after the paddle.

快频彩票kpcpIn general, sodium montmorillonite (or sodium bentonite) is better than calcium. However, the distribution of calcareous soil in the world is much wider than that of sodium soil. Therefore, in addition to strengthening the search for sodium soil, it is necessary to modify the calcareous soil to make it a sodium soil.

快频彩票kpcpBentonite (montmorillonite) can be used as binder, suspending agent, thixotropic agent, stabilizer, purification decolorizer, filler, feed, catalyst, etc. due to its good physical and chemical properties. It is widely used in agriculture, light industry and cosmetics. In the fields of medicines and the like, montmorillonite is a natural mineral material with a wide range of uses.
