Bentonite processing, bentonite processing equipment,mineral mill manufacturer in china shanghai.
Bentonite is the most commonly used processing equipment pendulum mill, and its specifications are 3R, 4R, 5R, 6R and the like. In addition, when modified bentonite , also often used wheel mill , grind mix screw extruder , extrusion equipment, drying time will be used bentonite dryer , the following are some common bentonite processing:
First, artificial sodium calcium bentonite process generally: calcium-based soil crushing ore → → adding sodium carbonate ( wet still need to add water ) → → rotary kiln dried mixed squeeze → → Pendulum Grinder mill air classifier → Na- earth products. Ore from the mine directly to the drying fields after harvest to dry naturally , so the moisture ore dropped from an average of 31% to 15% . After drying semi bentonite grinding dried before grinding or direct . Grinding fineness of 200 mesh and 100, 150 respectively , after drying drying reduces the moisture content below 12% after the packaging factory. The major products for the foundry , pellets, drilling mud .
Second, the active ( acidic ) clay machining processes generally: Bentonite → crushing → adding hydrochloric acid or sulfuric acid ( wet need to add water and dispersants ) → stir mixed squeeze → → → bentonite heated air dryer air classifier mill → → save. Sodium bentonite to produce strong bleaching, filtering speed, activated clay with low oil known . First artificial bentonite ore crushing , bound impurities stones, with a pass into the hot side of Raymond milling grinding dry. Bentonite powder grinding products as part of the sale , and the other part into the activated clay production lines, mainly deep-processing product variety , activated clay for moving purposes , vegetable and mineral oils bleaching, purification .
Third, the general process for organic bentonite processing : ore crushing → dispersion → → → purification modifications plus ammonium cover → rinsing → → → drying → crush → dehydration package .
Bentonite soil is not the same in different regions , so that the use of bentonite are not the same , not the same process , analyze specific issues , consult the bentonite and bentonite processing technology and processing equipment , please contact us.
