Project Background

Bentonite is a clay rock, also known as montmorillonite clay rock, often containing a small amount of illite, kaolinite, halloysite, chlorite, zeolite

What is bentonite?

Bentonite is a clay rock, also known as montmorillonite clay rock, often containing a small amount of illite, kaolinite, halloysite, chlorite, zeolite, quartz, feldspar, calcite, etc.; hardness 1 ~ 2, density 2 ~3g/cm3. According to the type, content and layer charge of montmorillonite exchangeable cations, bentonite can be divided into sodium bentonite (alkaline soil), calcium bentonite (alkaline soil), natural bleaching earth (acid soil or acid clay), among which Calcium-based bentonites include calcium sodium base and calcium magnesium base.

Processing technology of bentonite

The 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.

Shanghai SBM's new large-scale bentonite mill is a set of equipment for the development of large-scale, green and intelligent equipment. Its novel design, reasonable structure, small floor space, low power consumption, long operating life, low cost of wearing parts, high cost performance, etc., its technical performance has reached the international leading level.

Processing technology of bentonite

【Main use of bentonite】:

1. Drilling mud, flame retardant, filler: Because bentonite has good water swellability, dispersion and suspension and pulpability, it is used in drilling mud, flame retardant (suspended fire extinguishing), sewage treatment; also in the paper industry As a filler, it can optimize the performance of the coating such as adhesion, hiding power, water resistance, scrub resistance, etc.; because of its good adhesion, it can replace starch for yarn sizing in the textile industry. Raising, the odor is not emitted after the paddle, it is a double win.

2. Modify the calcareous soil to make it a sodium soil: In general, the properties of sodium montmorillonite (or sodium bentonite) are better than those of 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.

3, widely used in agriculture, light industry and cosmetics, pharmaceuticals and other fields: bentonite (montmorillonite) due to good physical and chemical properties, can be used as binders, suspending agents, thixotropic agents, stabilizers, purification decolorizers, filling Materials, feeds, catalysts, etc., are widely used in agriculture, light industry, cosmetics, pharmaceuticals, etc., so montmorillonite is a widely used natural mineral material.

4, paint filler: heavy requirements have a fineness of more than 2000 mesh and whiteness of 95 or more.

【Mainly applicable materials】:

Thixotropic agents, cosmetics, adhesives

Application field of bentonite

Bentonite (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.

Montmorillonite has adsorptive and cation exchange properties, which can be used to remove toxins from oil, gasoline and kerosene purification, and wastewater treatment;

Used for drilling mud and flame retardant (suspended fire extinguishing) due to its good water swellability and dispersion and suspension and pulping properties;

It can also be used as a filler in the paper industry to optimize the properties of the coating such as adhesion, hiding power, water resistance, scrub resistance, etc.

Because of its good adhesion, it can replace the starch used in the textile industry. The sizing of the yarn is both grain-saving and not hairy. After the paddle, it does not emit odor.
