HGM series grinding machine - can be used for calcite, barite, etc
Product features: Good stability, high reliability, advanced technology, long service life, easy maintenance. Product description: HGM calcite grindin
Product details
HGM Calcite Grinding MachineMainly suitable for medium and low hardness, Mohs hardness≤6Ultra fine powder processing of non flammable and explosive brittle materials, such as calcite, chalk, limestone, dolomite, carbon black, kaolin, bentonite, talc, mica, magnesite, illite, pyrophyllite, vermiculite, sepiolite, attapulgite, zeolite, diatomaceous earth, barite, gypsum, alum, graphite, fluorite, phosphate ore, potassium ore, pumice, etc100Multiple materials, fine powder finished product particle size in325-2500The yield can reach 325-2500 kilograms per hour by adjusting the size between 47-5 microns.
1.**The**
When the fineness of the finished product and the power of the motor are the same, the output is more than twice as high as that of the air flow mill, stirring mill, and ball mill.
2.Long service life of vulnerable parts
The grinding roller and grinding ring are forged from special materials, greatly improving their utilization. Under the same fineness of materials and finished products, the service life of worn parts is longer than that of impact crushers and turbine crushers2-5Multiple times, usually up to one year or more, when processing calcium carbonate and calcite, the service life can reach2-5Year.
3.High safety and reliability
Due to the absence of rolling bearings and screws in the grinding chamber, there is no problem of bearings and their seals being easily damaged, and there is no problem of screws becoming loose and damaging the machine.
4.High product fineness
The fineness of the product can be achieved in one goD97≤5μm.
5.Environmental protection and cleanliness
Using a pulse dust collector to capture dust and a muffler to reduce noise, it has the characteristics of environmental protection and cleanliness.
HGM8021 medium speed micro grinding powderThe complete configuration includes a hammer crusher, bucket elevator, storage bin, vibrating feeder, micro powder mill host, variable frequency classifier, dual cyclone powder collector, pulse dust removal system, high-pressure fan, air compressor, and electrical control system.
Large pieces of material are crushed into small particles by a hammer crusher and then sent to the storage bin by a hoist. After passing through a vibrating feeder and an inclined feeding pipe, the material is evenly delivered to the upper part of the turntable's bulk tray.
The material disperses around the circumference under the action of centrifugal force and falls into the raceway of the grinding ring, where it is impacted, rolled, and ground by the ring rollers. After being processed into powder through three layers of raceway, the high-pressure fan sucks in external air into the machine through suction and brings the crushed material into the powder selection machine.
The rotating impeller inside the powder selector causes the coarse material to fall back and be re ground. The fine powder that meets the requirements enters the cyclone powder collector with the airflow and is discharged by the discharge valve at the bottom, which is the finished product. The airflow with a small amount of fine dust is purified by the pulse dust collector and discharged through the fan and muffler.
