Magnesium hydroxide is a colorless hexagonal crystal or white powder, insoluble in water and alcohol, soluble in dilute acid and ammonium salt solution, the aqueous solution was weakly alkaline.
Magnesium hydroxide is recognized as an excellent flame retardant with three functions of flame retardancy, smoke suppression and filling in the rubber and plastic industry. It’s widely used in rubber, chemicals, building materials, plastics and electronics, unsaturated polyester and paint, coatings and other polymer materials. Especially for the mine air duct coating cloth, PVC whole core transport belt, flame retardant aluminum panels, flame retardant tarpaulin, PVC wire and cable materials, mining cable sheath, cable accessories flame retardant, smoke and antistatic , Can replace aluminum hydroxide, with excellent flame retardant effect. Compared with similar inorganic flame retardants, magnesium hydroxide has a better smoke suppressing effect. Magnesium hydroxide in the production, use and disposal of non-hazardous substances in emissions, but also to neutralize the combustion process of acid and corrosive gases. When used alone, the amount is generally 40% to 60%.
For Magnesium hydroxide Raymond grinding mill. Guilin hengda HD series high efficiency raymond grinding mill is a good choice, it breakthrough the bottleneck of the grinding mill, the production is 20-30% higher than traditional raymond mill, The increase mechanism of linkage pressure of the rollers, which greatly prolongs the useful life of the equipment and increases the capacity by 20% under the same power. With the original roller assembly, the oiling time increased 6 – 15 times, achieve the application of oil once, use for 30-45 days.Higher Accuracy powder Classify, without coarseness missing, e accuracy is 80-600 meshes. The classify efficiency reached 99%. HD series has the advantages of high production, high qualification rate Low noise and vibration in grinding of the 325-400 meshes.
HD series high efficiency raymond grinding mill specifications:
Max feeding size: ≤35mm
Main motor power：45-315KW
Final product size: 80-400 mesh
Applications : For non-metallic minerals with a Mohs hardness of 6 or less and moisture content of 6% or less, it has a high productivity and high grinding power, such as talc, calcite, calcium carbonate, dolomite, , Kaolin, clay, graphite, , zircon sand, bentonite and other non-metallic minerals.
