High powered pulverizer Producted by Liming

High powered pulverizer is mainly applied to the powder processing of mineral products in industries of metallurgy, construction, chemistry, Fertilizer and mining etc. It can produce powder from non-flammable and non-explosive mineral materials with Mohs hardness below 9 and humidity below 8%, such as barite, limestone, quartz, calcite, granite, porcelain clay, basalt, gypsum etc

High powered pulverizer is designed to get fine and super fine powder. It is mainly used to process more than 200 kinds of non-inflammable, non-explosive and brittle materials with Moh’s hardness below 6 scale, such as calcite, chalk, limestone, dolomite, kaolin, bentonite, talc, mica, magnesite, illite, pyrophyllite, vermiculite, sepiolite, attapulgite, tablite, ceyssatite, barite, gypsum, alunite, black lead, fluorite, phosphate rock, potassium ore, floatstone etc. When HGM mills are used to process materials with Moh’s hardness between 4-6 scale, the service lifetime of easy-worn parts shall be shortened as it relies on the hardness of raw material.

Working process of High powered pulverizer:

Crushed materiel is sent into hopper by elevating conveyor, and then sent into grinding chamber of host machine by vibrating feeder. Then materiel in grinding chamber is scooped up by scraper and kneaded between grinding roller and grinding ring. Then pulverizer will be blown into the analyzer by blower, where it will undergo pneumatic separation. Coarse particles will be milled again. The acceptable powder will be blown into the cyclone collector. Then the particles are separated from the air current and discharged as finished powder.

Advantage and Characteristics:

High powered pulverizer 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.
