Description

A kind of can sub-elect thick in the high-efficient powder concentrator of thin three kinds of grain diameter component materials
One, technical field:
The utility model relates to a kind of granular material sorting or granule materials grading plant, especially relate to a kind of can sub-elect thick in the high-efficient powder concentrator of thin three kinds of grain diameter component materials.
Two, background technology:
Powder concentrator is the visual plant of cement grinding system, from the centrifugal classifier of the first generation to cyclone type powder sorting machine, a large amount of up till now eddy current powder concentrators that have cage rotor that use, technical had a very much progress, shifted the cement industry development to a certain extent onto.Particularly the grinding system of the band roll squeezers that used in a large number in recent years makes the output of system increase substantially.This system is higher to the degree of dependence of powder concentrator, and the effect of powder concentrator is particularly important.But, the present powder concentrator that uses, no matter structure how, all be that material enters powder concentrator, can only divide and elect finished product as and return powder (meal) two large divisions that Hui Fenzhong contains the bigger material of particle, also contain a large amount of satisfactory fine powder materials, it is very big that particle is formed deviation, reenters the grinding machine grinding, reduced system effectiveness.With the grinding system of roll squeezer, adopt V-type powder concentrator or the beater sorting material through the roll squeezer extruding usually as the aforementioned, the raw meal particle size that provides to ball mill when adopting the V-arrangement powder concentrator is thinner, usually d90 ≈ 0.2-0.3mm; The raw meal particle size that provides to ball mill when adopting the scattering and grading machine is thick slightly, d 90≈ 2mm.As can be seen, no matter adopt the sort of classifying equipoment, mill feed material size is all bigger, it is also bigger that particle is formed deviation, causes ball mill must leave enough broken spaces, and it is bigger to make that grinding machine one storehouse is stayed, the abrasive body average ball diameter must be big, in a word, can not give full play to the grinding advantage of ball mill.
In addition, present powder concentrator mostly is the top charging, and equipment must have a cover material charging and a decentralized system, causes the powder concentrator complex structure, and has the unfavorable problem of dispersion effect, makes grinding efficiency reduce.The O-Sepa powder concentrator of Japan little wild field company is the representative of cage high-efficient powder concentrator.TSV ~ 4500HF the powder concentrator of France is the better powder concentrator of present performance, and characteristics are: bottom air intake, top charging.In the awl tube, form the ascending air of eddy current rotation,, make the into interior stock grading of people's powder concentrator by the rotation of variable vane and rotor.Wind moves upward from the bottom, can avoid the generation of wind-force short circuit phenomenon in the machine, guarantees that its inside can not produce dust stratification.Adopt the rotating speed of variable frequency regulating speed control cage rotor, make the classification force intensity can pass through to change speed of mainshaft flexible modulation, to reach the purpose of control product quality.
Three, utility model content:
