Fluorite Raymond mill separation process and technical analysis

Fluorite Raymond mill characteristics

1. Simple system structure, compact layout, smooth process and small investment. Due to no electrostatic precipitator or big cloth bag dust catcher system, so to save a large amount of investment, and covers an area of, but considering the circulation wind contain very small amounts of dust on the fan impeller has some wear and so on fan type selection by using the wear-resisting of medium speed fan, to ensure the service life of fan.

2. The system adopts negative pressure and closed circulation without secondary pollution. The system exhausts the air into the finished fine ash storehouse, USES the top of the storehouse cloth bag filter, avoids the environment pollution of the annular ramon mill, guarantees to meet the national one class area emission standard. At the same time, closed-circuit circulation in the transmission pipeline thermal ash is not affected by meteorological conditions, moisture absorption small, no condensation, can greatly reduce the influence of air humidity on separation efficiency.

3. The system has good sealing and no leakage, which ensures the separation efficiency of the system. Because the system is negative pressure separation system, so in addition to the system pipeline and equipment joint should seal, eddy current separator and cyclone separator unloading gas lock is very important, locking air is bad, will seriously affect the separation efficiency of system. This system chooses the company for this special locks gas discharging device, it is composed of sampling gate and electric crusher manufacturers lock gas composition, negative pressure can be effectively separated separation system and between the rolls of positive pressure air mix, guaranteeing the sorting system is not affected by grey pressure Chambers, and ash smoothly into the library, at the same time sampling system is simple, convenient and fast.

Fluorite Raymond mill works

Power supply system for high pressure centrifugal fan, under the action of negative pressure in the system, Fluorite by speed feeder Chambers (the original grey connected directly take ash) evenly by negative pressure suction duct, after mixing with air in pipe into the first stage separation equipment - eddy current separator (general layout in coarse grey library), formed in the vortex separator forced vortex, coarse particles rotating vortex area is overcome negative pressure produced by centrifugal force is flung to the wall or collision with reflector screen capture, relying on its own gravity discharge; The fine particles are sucked away by the negative pressure in the eddy current area and discharged by the vortex shells on both sides, so as to separate the coarse and fine particles. In fact, due to the aggregation of particles and the entrainment of large particles, there is always some fine ash mixed into coarse ash.

In order to reduce the crude ash of fine ash content, in the position of the vortex separator is at the bottom of the thick ash discharge set up secondary air import, massive particles can pass through the wind curtain and discharge, the quality of small particles is the wind vortex shell back to the screen, thus improve the separation efficiency of system. At the same time, the strength of secondary air curtain can be adjusted to adjust the fineness of finished ash, so as to meet the requirements of different users. The spiral case of fine ash, the airflow into the second stage separation equipment - cyclone separator (general layout in fine ash library roof) to realize gas ash separation, the rest of the few super fine dust in tail gas by the high pressure centrifugal fan (general layout in grey library near zero meters) in the feed to mix with the material for the next cycle.
