Technical field
The present invention relates to powder concentrator device field, specially a kind of dedicated powder concentrator of the sandstone of coal mill system.
Background technique
Coal power separator is mainly used as the classifying equipoment in cement plant pulverized coal preparation (grinding) system.Wherein, V-type powder concentrator
It is one of main powder concentrator type, the working principle of V-type powder concentrator are as follows: material is entered in separation chamber by blast pipe with air-flow, warp
Selection by winnowing plate selection by winnowing in winnowing machine, changes direction through guide vane, forms the air-flow of rotation, sort to material, fine powder with
Air-flow is discharged from air outlet, then coarse powder is discharged from the bottom of separation chamber, is then return in press-roller device by collecting in separation chamber
Coarse powder is crushed again, until obtaining qualified fine powder.
Powder concentrator in the prior art when in use, has the following problems: 1, due to the small volume of V-type winnowing machine, because
This, powder is shorter in the selection by winnowing indoor residence time so that the screening error of powder is larger, part bulky grain coarse powder also directly from
Air outlet discharge, causes the selection result poor；2, the drying effect of existing powder concentrator is poor, it is difficult to fast and effectively dry to dust
It is dry.Therefore it is badly in need of a energy flash baking material, and effectively extends material in the selection by winnowing indoor selection by winnowing time, realizes fine sieve
Material is selected, fine powder and coarse powder are obtained.
