High pressure micro grinding mill overview

Flour milling industry in the industrial machinery , gypsum powder processing industries account for a large proportion. Gypsum powder is one of the five gel material, in the national economy plays an important role, widely used in construction, building materials, industrial molds and art model, the chemical industry and agriculture, food processing and pharmaceutical cosmetic and many other applications, is a important industrial raw materials.

Gypsum powder production of raw materials are natural gypsum ore, mineral resources of natural gypsum reserves of total reserves of nearly 600 million tons, ranking first in the world, but also chemical gypsum manufacturing country, every year a large number of chemical gypsum generated: only the year of phosphogypsum As many as nearly 20 million tons, and partly the accumulation of phosphogypsum, the amount of phosphate up to a thousand tons, especially with the rapid development of China’s economy and the importance of environmental protection in recent years, has become the power plants to power plant desulfurization technology areas, resulting in a large number of gypsum, in addition to citric acid gypsum, fluorine gypsum, salt, gypsum and other chemical gypsum, relying on abundant natural and human resources to carry out comprehensive utilization, the development of gypsum industry is building a circular economy, even more highlight the many new investors. Gypsum production process can be complex and how effective use of existing resources with the least cost to obtain the greatest benefits? A product that meets: Bamako Sand advantage of this machine not list them.

Gypsum powder production line process

can be summarized as follows: Gypsum Ore feeder → jaw crusher bucket elevator raw materials warehouse → mill → boiling bucket elevator bucket elevator furnace → clinker conveyor warehouse cooling, storage → finished product. Grinding part of which is particularly critical. Shanghai mill is grinding equipment by domestic and foreign similar products, advanced structure and new cone break in the industry updated on the basis of improved design made especially for the processing of gypsum powder production. The device efficiency than conventional milling machines, low power consumption, small footprint, one-time small investment. Roller under the action of the centrifugal force of the tightly compacted in the grinding ring, so when the roller, grinding ring wear to a certain thickness of the finished product does not affect the yield and fineness. Roller, grinding ring replacement cycle is long, thus removing the vulnerability of the centrifugal mill short replacement cycle defects.

Working principle and Advantages of HGM Micro Powder Grinding Mill

Micro Powder Grinding Mill is a new type of mill for making super fine powder through more than 20 times of test and improvement. The fineness can reach to 0.006mm; Micro Powder Mill is mainly used for processing gypsum, calcspar, talc, and other materials used in painting, pigment and cosmetics industry. Compared with jet mill, it is economic-cost, high-capacity, and the spare parts just need to exchange once a year; the bag filter is added to protect the environment.

Working Principle:
The motor drives the main shaft and every turn plate through the reducer. The reducer drives dozens of rollers to rotate against race way of ring through pin. Small material crushed by crusher is transported into hopper by elevator, and then vibrating feeder shall feed material to the central part of upper turn plate evenly. The material falls to circle under the centrifugal force and comes down to raceway of ring to be crushed into powder. After grinded in the first race way, the material goes to the second and third turn plate. The blower inhales the external air into the mill and carries the powder after third turn plate into powder-separator. Turbine in the separator makes the coarse powder drop down and regrinded and the fine powder shall go into cyclone powder collector together with air current and go down through discharge valve as final product; at the same time, air current with a little dust goes out through blower and muffler after purified by filter.

Advantage and Characteristics:
HGM Micro Powder Grinding Mill has high efficiency and low cost. Its capacity is raised by 40% compared with airflow mill and mix mill on the condition that the materials, the drive and the fineness of the final powder are the same. The life span of tear & wear parts is more than that of straight impact crusher and turbine mill under the circumstance of same materials and fineness of the final powder. Usually, its life span is more than one year. There is no rolling bearing and screw in the grinding cavity, so as to avoid the damage to the machine caused by tear & wear of bearing and seals and the looseness of screws. The fineness of powder can reach ≦5μm with d97 once.
