What is Bentonite?
Bentonite is a clay dominated by montmorillonite.
Montmorillonite is a water-bearing aluminosilicate mineral with negative charge between the mineral layers. It can absorb Ca2+, Mg2+, K*, Na* and other cations, and has the property of cation exchange.
After absorbing water, bentonite can expand in the direction of C axis between the montmorillonite layers and form a gel with good performance when dispersed in water.
Natural bentonite as much as the calcium base bentonite, not very ideal, its physical and chemical properties such as processed into its purification of sodium base bentonite, bentonite, granular bentonite, organic bentonite, activated clay particles (clay), such as inorganic gel of bentonite processing products, can be widely used in petrochemical, oil, medicine, construction, chemical, textile, coating, in various fields such as metallurgy, environmental protection.
Bentonite is produced in many places in China, such as Inner Mongolia, Liaoning, Heilongjiang, Jilin, Hebei, Henan, Zhejiang, Hubei,
Xinjiang, Shanxi, Jiangxi and other places have output.
Bentonite because of its good physical and chemical properties, known as the "versatile" clay
Said that it can be used as binder, suspension agent, thixotropic agent, stabilizer, purification and decolorization agent, filler, feed, catalyst, etc., widely
Used in metallurgy, petroleum, foundry, food, chemical, environmental protection and other industrial sectors .
Usage of Bentonite
Foundry industry. 200 bentonite is used as a binder for molding sand, a binder for hydrated molding sand and a surface stabilizer
Metallurgy. 325 bentonite can be used as pellet binder for iron concentrate
Drilling mud. 325 bentonite can be used to prepare drilling mud suspension and detaching agent with high rheological and thixotropic properties
Food. 200 bentonite can be used for decolorization and purification of animal and vegetable oils, clarification of wine and juice, stabilization of beer, saccharification and purification of sugar juice.
Petroleum. In the petroleum industry, bentonite can be used for the decolorization and purification of petroleum, grease, paraffin, and paraffin oils.
At the same time, it is also a very good catalyst carrier for oil cracking.A thickening agent for the preparation of tar-water emulsion asphalt surface stabilizer lubricating oil (grease)
Agricultural. Soil improver compost additive animal feed additive, binder, improve feed utilization liftActive white earth poultry meat production, egg rate, animal enclosure soil (deodorization and disinfection)
Textile printing and dyeing filling. Bleaching antistatic coating instead of starch sizing and printing paste
Chemical catalyst. Pesticide, pesticide and fungicide carrier rubber and plastic filler
Paint. Applied in water-based paint ink deposition inhibitor
Water purification and sewage treatment. industrial wastewater (liquid) swimming pool water purification food industrial waste disposal of radioactive waste adsorbents
Civil and construction.The suspension of the slurry tank, the stabilizer of the soil, the lubricant of tamping, the plasticizer of concrete, the seepage prevention of the cement mixing material poolPaper making. Used as dyeing agent and pigment filler for carbon paper
Ceramic industry.Plasticizer for ceramic raw materials (to improve the compressive strength of ceramic body)
Machinery industry. High temperature lubricant
Raymond mill selection and technological process in Bentonite powder processing

Bentonite powder processing technological process
Phase one: raw material crushing
Bentonite blocks will be crushed to 15mm-50mm fineness by crusher.
Phase two: grinding
Crushed bentonite material will be sent to the storage hopper by the elevator, and than the feeder will send the material to the main mill for grinding.
Phase three: classifying
Ground material will be classified, coarse powder will fall back to the main mill to be ground again.
Phase four: production collecting
Qualified powder will flow with the air and be collected in the dust catcher, then the finished powder will be transported to the product storage bin through discharge port. Lastly, the powder will be loaded by tank car or packed by packing machine.
