HGM series limestoneGrinding machine (ultrafine grinding machine)Mainly 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.

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
HGM series limestoneGrinding machine (ultrafine grinding machine)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
HGM series limestoneGrinding machine (ultrafine grinding machine)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.

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.
