BACKGROUND

Calcium carbonate is the largest inorganic filler in the industry, such as building materials, papermaking, plastic, rubber, paint, coating and so on. Due to the high cost, the market is wide and the demand at home and abroad has been great. At present, the production of calcium carbonate on the market is mainly the traditional Raymond Mill, ball mill, etc., there are high energy consumption, low efficiency, poor stability, finished particle size is not control, serious pollution and other problems. Therefore, in order to meet the global environmental requirements and the market demand for calcium carbonate quality, select the appropriate calcium carbonate processing technology and equipment is particularly important.

APPLICATION

PRODUCTION PROCESS

Heavy calcium carbonate is a natural calcite, marble, dolomite or chalk as raw material, the mechanical equipment grinding and grading to achieve a certain degree of fine powder products. Calcium carbonate production process has two kinds of dry and wet, from the market demand for heavy calcium powder point of view, most concentrated in the 3000 or less, the process is mainly produced by dry process, the process is: hand from the quarry the calcite, limestone, chalk, shells and so on to remove the gangue, and then crushed with the crusher on the raw materials, and then calcium carbonate grinding machine to get fine limestone powder, after the classification of limestone powder grading, meet the particle size requirements of the powder as a product packaging storage, do not meet the return of calcium carbonate grinding mill again grinding.

EQUIPMENT

According to the market demand for different areas of heavy calcium powder, Kefid after years of practice, devote themselves to research and development for a full set of tungsten powder grinding equipment, which covers the fine sand, coarse powder, fine powder, micro powder and other fields, according to customer fineness, production, investment and other requirements can be diversified options.

RELATIVE EQUIPMENT

• 

Jaw Crusher

Mainly used for a variety of ore and large pieces of medium material size broken, can be broken compressive strength of not more than 320Mpa material, sub-rough and fine broken two, is the primary broken preferred equipment.

Automatic quantitative powder packaging machine

Mainly for high mobility, the average particle size of the powder in the 80-2500 mesh mineral powder, such as talc, heavy calcium carbonate, barite, silica and other powder products designed for packaging machines.

Multi - rotor air classifier

Grading machine and cyclone separator, dust collector, induced draft fan to form a grading system. Material under the action of the fan under the action of the sub-class machine from the lower end of the inlet with the rising air flow to the grading area in the high-speed rotation of the grading turbine generated by a strong centrifugal force under the effect of separation of coarse materials and fine materials.

Powder surface modification machine

Not only can improve the compatibility of inorganic mineral filler and organic polymer, improve the interface binding force, enhance the mechanical strength of materials and comprehensive performance, but also greatly improve the filling of the filler, reduce production costs, but also to give product special performance.
