Introduce the use of alkaline magnesia products---reburned magnesia manufacturers

Alkaline magnesia is mainly divided into three types, light-burned magnesia, heavy-burned magnesia, mid-range magnesia, 397 fused magnesia types of magnesia uses different ore and production equipment, and the quality of the produced magnesia is different. , The application field is also different, the following heavy-burned magnesia manufacturers will introduce you in detail the difference between the 6 kinds of magnesia; light-burned magnesia powder

1. Light-burned magnesia mainly uses high-quality small flower magnesite ore with a content of 41%-47%. The magnesite ore passes through a light-burned reflector kiln. After the coal is burned, the coal gas is calcined to produce ash (semi-finished) The mask is crushed to 80 mesh, 100 mesh, 120 mesh, 150 mesh, 180 mesh, 200 mesh, 250 mesh, 300 mesh, 325 mesh, etc. Generally, the content of light-burned magnesium oxide is between 60%-95%. The products of light-burned magnesium oxide are mainly for the production of feed, fertilizer, magnesium sulfate, manhole covers, insulation boards, fire protection boards, art fences, door core boards, composite insulation boards, and firecrackers. Fixing agent, chicken house, inorganic glass, magnesite tile, grinding wheel mold, artificial marble, hanger chassis, magnesite pit, solar biogas tank, ventilation pipe, lightweight partition board, vegetable greenhouse, building material abrasive tool, ceramic tile Ideal raw material for bottom powder, papermaking, sewage treatment, steelmaking slag, heating flue gas boiler desulfurization, power plant boiler desulfurization and other products.

2. The medium-grade magnesia is made of light-burned magnesia with more than 92% as the main raw material, finely ground, pressed ball, and sintered in a high-temperature shaft kiln. Usually the content of mid-range magnesium oxide is between 94.5% and 95.5%. The content of mid-range magnesium oxide is low, with high bulk density and good slag resistance. It is suitable for manufacturing mid-range magnesia bricks or magnesia unshaped refractory materials.

3. Re-burned magnesia is made of 46%-46.5% magnesite and sintered in iron shaft kiln. MgO content is high, usually the content of re-burned magnesia is between 90-93%, which is the raw material for the production of ordinary magnesia bricks and monolithic refractories.
