Barite grinder mill is mainly applied in the non-explosive brittle material ultra-fine powder processing, low hardness, Mohs hardness of ≤ 6, such as calcite, chalk, limestone, dolomite, silica, kaolinbentonite, talc, mica, magnesite, illite, pyrophyllite, vermiculite, sepiolite, attapulgite, tired rectorite, diatomite, barite, gypsum, alunite, graphite, fluorite, phosphorusore, potassium ore pumice, etc. more than 100 kinds of materials, fine finished particle size be adjusted between 325-3000 mesh, yield up to 0.7-7.5 tons per hour.
Barite grinder mill features
1.Efficiency, energy saving
In the case of the same product fineness and the motor power than airflow mill, vertical mill, ball mill production more than doubled.
2.Long life wearing parts
Grinding roller and grinding ring using special materials forging the system, thus greatly enhance the degree of utilization. Materials and finished product fineness of the same case, longer than the impact crusher and turbine crusher wear parts life of 2-5 times, usually up to one year or more, the processing of calcium carbonate, calcite, the service life of up to 2 5 years.
3.High security and reliability
Bearings, grinding cavity without screws, so there is the problem of the bearings and seals vulnerable, there is no screw loosening and destruction of the machine.
4.Product fineness
Product fineness can be a one-time to reach the D97 ≤ 5μm.
5.Environmental protection, clean
Pulse filter to capture dust, the use of the muffler to reduce noise, environmentally friendly, clean features.
Barite grinder mill equipment composition
Barite grinder mill complete configuration includes a hammer crusher, bucket elevators, storage silos, vibration feeder, micro grinding the host, frequency classifier, double cyclone powder collector, pulse dust removal system, high pressure air, air compressor, electrical control systems.
Barite grinder mill working principle
(1)when working host motor through reducer drive shaft and turntable rotation dial edge of the roll pin driven by dozens of roll grinding in the grinding ring raceway within the scroll.
(2)The bulk material by the hammer crusher broken into small particles by the elevator into the storage silos, and then through the vibration feeder and the tilt of the feed tube, the material uniformly to the bulk material of the upper turntable plate.
(3)Material scattered to the circle surrounding the effect of centrifugal force and fall into the grinding ring raceway ring roller impact, rolling rolling, grinding, after the processing of three-ring Road into powder, high pressure air through the pumping action of the external airinhalation machine, and the crushed material with selected powder machine.
(4)Coarse material down the rotation of the impeller in the powder re-grinding, discharge shall be finished by the lower part of the discharge valve to meet the requirements of the powder into the cyclone powder collector with air current, and the airflow with a small amount of fine dustdischarged through blower and muffler after the purification of the pulse dust collector.
