For my much more early employing of wind sweep Coal mill method within the, commonly used rough powder separation players, is we normally by said of static chosen powder machine, it not with energy, as cage shaped rotor of improvement, no energy of static selected powder machine development into has with energy of dynamic chosen powder machine, it not simply boost has selected powder of efficiency, also considerably improve has chosen powder machine of processing capacity, in my wind sweep Coal mill method within the get has widely of application.
Static high efficiency separators: Static high efficiency separators or higher efficiency separators of basic structure, lack of moving components, air-swept mill grinding program with dust or other air separation products, commonly also called static higher efficiency separator of coarse pulverized-coal High efficiency separator. Common static high efficiency separator structure diagram.http://www.jianyemachine.com/upfile/2014/03/17/20140317110557_705.jpg
Its functioning principle is supplies by air from outdoors with chosen powder at the bottom between the cone along with the powder Cone, cross section expanded, reduce wind speed, coarse granule subsidence precipitation. And because the airflow becomes tangential Rotary, centrifugal separation, separation of coarse particles discharged from the outlet. Guide of your upper air flow by way of the adjustable angle fan into the inner cone, dust the airflow cooling fan-affected, downward spiral via the inner left inner cone like a cyclone. This secondary separation of coarse particles by way of diversion discharge Cone, fine particles from the airflow to be taken out by one more cyclone recovery.High Stress Grinder Mill
Static high efficiency separator is usually adjusted by way of the following several points:
1, the speed of rising air. Increase the muzzle velocity of air to separate size becomes so powerful, which in turn reduced muzzle velocity of air separation and particle sizes thinner. At low air speeds, really fine granularity.
two, leads the wind angle. Angle adjustment to radial, and tangential velocity of 90 ?? will be the smallest, minimum centrifugal force, separation size Max. Within the selection of 30 ??-75 ??, angle increases, separation size steadily thickens. Within the case of air speed doesn’t transform, can be adjusted in fineness involving 7%-20%, adjusted for around three. Viewpoint of larger, had small impact. When elevated air speed and wind angle joint adjustments with an proper overlay effects.
3, Cone and cylinder gap, intended to allow the partial load flow via right here to bypass into the powder space. Such as tiny gaps, bypass air much less, soon after the outer cone of dust gas received ahead of time are separated clearly, but resistance has improved.
four, inner height, further altering the cutting diameter.
Main disadvantage is the fact that the adjustment on the static higher efficiency separator is narrower, powder and significantly less efficient. Major advantage is actually a somewhat very simple structure. If segregation just isn’t high, and may be further simplified, cone, tube adjust the pipeline may be canceled.
