A kind of flour mill with elevator
It the utility model is related to grinding machinery technical field, more particularly to a kind of flour mill with elevator.
It is frequently necessary to use flour mill progress attrition grinding during materiel machining, due between the mixing roll of flour mill having
There is certain gap, only grind the material kind of one time and also include the larger slag charge of particle, it is necessary to be carried out to these slag charges on secondary
Material makes it reenter grinder, this just needs to screen the material after grinding.Screening plant of the prior art is logical
Vibrating screen realization is crossed, since vibrating screen noise is larger in real work, serious infringement is caused to the ear-drum of staff.Separately
Outside, the secondary feeding work of slag charge generally relies on wind turbine and provides power, and the slag charge for the motor spindle that is milled is re-delivered to top
In hopper, when slag charge is more, wind turbine conveys less efficient, and easily blocks, in use to have inconvenience more.
