Further, the crosspoint of the center line of two neighboring rotor is located on the center line of fine powder discharge barrel, demarcation strip
The region of classification air-flow is not influenced on the angular bisector of the rotor of its adjacent both sides or.
Preferably, the angle between the center line of two neighboring rotor is 90 °, and the angle between two neighboring demarcation strip is
90°。
In the utility model, the upper end of powder drum body is selected to be equipped with the end cap that sealing is set on fine powder discharge barrel, demarcation strip
Upper end is fixed on the lower face of end cap.
In the utility model, select the central axis of powder drum body, coarse powder collecting pipe and fine powder discharge barrel three to overlap and set.
According to the disposal ability of powder concentrator, the rotor quantity of setting is at least one.
The utility model further includes controller, and controller controls multiple motors to work asynchronously at the same time, automatically controlled to realize multiple turns
Rotor speed is identical, and error is within ± 5%.In the utility model, rotor and motor use direct-connected mode, and rotor uses horizontal knot
Structure, motor use variable-frequency motor, and more frequency converters can be adjusted in synchronism rotor speed, multiple turns of the unanimously guarantee of multiple rotor speeds
The uniformity of son classification.Cut size can be changed by changing rotating speed, meet the needs of different product gradings.
Beneficial effect:Increase demarcation strip between adjacent rotor, demarcation strip can be installed on the centre position of two rotors or not shadow
The intermediate region of classification air-flow is rung, adjacent rotor is separated, such rotor is each working in relatively independent space, during work
It will not influence each other, avoid running thick phenomenon caused by adjacent rotor influences each other.The utility model can eliminate more rotor choosings
Influencing each other between powder machine adjacent rotor, can effectively improve powder concentrator selects powder precision, and improve powder concentrator selects mealiness energy, drop
Low large granular materials enter the possibilities of finished product.It can be used in the separation of superfine powder, product granularity can be used in up to 1 ~ 45 μm
The industries such as miberal powder, metal dust, chemical materials, fine ceramics, food, environmental friendly material.
