dolomite powder grinding mill
Source: clirik By Administrator Posted: 2021-07-06Dolomite is a carbonate mineral with iron dolomite and manganese dolomite, respectively. Its crystal structure is like a square stone, often with a diamond face. When cold dilute hydrochloric acid is cold, it bubbles slowly. Some dolomites glow orange with cathode rays.
Dolomite is the main mineral component that makes up dolomite and dolomite ash rock. Dolomite can be used in building materials, ceramics, glass and refractory materials, chemicals and agriculture, environmental protection, energy conservation and other fields.
It is mainly used as a melting agent for alkaline refractory materials and blast furnace iron making, for the production of calcium and magnesium phosphorus fertilizer and for the production of magnesium sulfate, and for the production of glass and ceramic ingredients.
The mining and development of dolomite has also driven the development of grinding mill machinery, crushing machinery industry. In the process of dolomite utilization must be used to crush it to a certain size, and then through the grinder to grind it to a certain degree of fineness, in order to make full use of in industry.
The development of grinding machinery has brought protection to the processing of dolomite, through the processing of dolomite can be processed to ultra-fine powder (general fineness of 325 to 3000 eyes), the use of processed dolomite has been greatly improved, expanding its application area.
Shanghai CLIRIK Machinery Co., Ltd. production of ultra-fine powder grinding mill machine (three ring medium speed grinding machine) can be effective processing of dolomite, the grinding machine has a disposable powder, less power consumption, more skilled and environmentally friendly characteristics. At present, it is dolomite processing equipment.
1. The structure of the dolomite grinder:
Dolomite grinder Full set of configuration includes hammer crusher, bucket lifter, storage tank, vibration feeder, grinder host, variable frequency grader, double cyclone powder collector, pulse dust removal system, high-pressure fan, air compressor, electrical control system.
2. How the dolomite grinder works:
When working, the grinding machine main motor drives the spindle and turntable rotation through the reducer, and the roller pin at the edge of the turntable drives dozens of rollers to roll in the grinding ring raceway.
The dolomite raw ore material is broken into small particles by the hammer crusher and then fed into the storage tank by the lifter, and then through the vibration feeder and the tilted feed tube, the dolomite particles are evenly delivered to the upper bulk plate of the turntable.
Dolomite particles in the centrifugal force scattered to the perimeter of the circle, and fell into the roller of the grinding ring by the ring roller impact, rolling, grinding, after the processing of the three-layer ring into dolomite powder, high-pressure fan through suction action will be the external air inhaler, and crushed dolomite powder belt into the powder machine.
The rotating impeller in the powder picker makes the coarse dolomite powder fall back and re-grind, the fine powder that meets the requirements enters the cyclone powder collector with the air flow and is discharged by the discharge valve at the lower part of it, which is the final dolomite ultrafine powder, while the air flow with a small amount of fine dust is purified by the pulse duster and discharged through the fan and muffler.
3. Performance characteristics of dolomite grinders:
♦ High efficiency
In the case of dolomite powder finished product fineness and motor power is the same, dolomite ultra-fine grinding machine than air flow grinding, stirring grinding, ball mill output is more than double;
♦ The consumables have a long service life
Grinding rollers and grinding rings are forged from special materials, which greatly improves durability. In the case of the same fineness of materials and finished products, dolomite ultra-fine grinder fragile parts than impact crushers and turbine crushers consumables life of 2-3 times longer, generally up to more than one year; This grinder in the processing of calcium carbonate, calcite, the service life of up to 2-5 years;
♦ High safety and reliability
Because there are no rolling bearings and screws in the grinding cavity, there is no problem of the bearing and its seals being fragile, or of destroying the machine due to lose screws;
♦ High product fineness
By this grinding machine processed by the white dolomite powder finished product fineness can reach D97≤5 m;
♦ Small environmental pollution
The use of environmentally friendly pulse dust removers and silencers in grinder equipment greatly reduces dust and noise pollution to the surrounding environment.
