In the Bentonite powder production process,
Coarse powder mill is used as grinding machine to grind bentonite ores into powder.
MXB series coarse powder mill specializes in pre-processing of various coarse powder materials, such as sand abrasives. Compared to traditional ball mill and Raymond mill, MXB coarse powder mill features with higher capacity and more function.
Coarse Powder Grinder Working Principle:
Disc drive motor through reducer rotating air lock feeder through the material feed port fell from the central disc, while hot air from the air inlet into the mill. With the disc's rotation, the material under the action of centrifugal force to the disc edge and moved across the disc when the annular groove on the roller by rolling and grinding, grinding the material in the disc after the edge of high-speed air ring with the wind, the large Straight into the disc particles to re-grinding, air flow through the upper part of separator material, the effect of the rotating rotor, meals bucket fell from the cone disc re-grinding, qualified with a grinding powder with the air flow through the income Dust collection devices, that is, products, materials containing water contact with the hot air drying process is, by adjusting the air temperature, humidity materials to meet different requirements, meet the requirements of the product water. By adjusting the separation can be achieved by the required granularity of different products.
Coarse powder mill for Bentonite powder production process
Processing methods used in the production of sodium-activated bentonite depend on the deposit and its geographical location. They could include several of the following:
Selective mining.
Field laying and rotavation. This is a process used in hot, dry climates where the bentonite is spread out and rotavated with the addition of sodium carbonate.
Crushing to 50 mm maximum size at the production plant.
Extrusion. In wet climates, where field laying is not possible, a blend of raw bentonite and sodium carbonate is extruded to promote activation.
Drying by rotary louvre drier to optimum moisture contents in the range 11 to 22 % of dry weight.
Milling to a particle size that promotes good powder flow but does not diminish clay performance. Generally, powders with 95 % of particles less than 150 microns (dry sieve basis) are used
SBM offer ball mill, SCM ultrafine mill, raymond mill, Coarse powder mill for Bentonite powder manufacturing.
