Description

Cross roll waterfall material flour mill
(1) technical field:
The present invention relates to powder process equipment, is a kind of cross roll waterfall material flour mill specifically.
(2) background technology:
Flour mill is breeze sector application equipment the most widely.
A kind of universal architecture of flour mill main frame is: main machine base is equipped with hollow central shaft bracket and coaxial bull ring and cover cylinder, main frame main shaft is located in central shaft bracket, fixed roll frame (or claiming plum blossom frame) is equipped with in the main frame main shaft upper end of stretching outside central shaft bracket, the grinding roller assembly of circle distribution is located on fixed roll frame, in the process of revolution of grinding roller assembly, grinding roller assembly makes to keep Structure deformation between each grinding roller and bull ring by centrifugal action, crushing material to be reached the object of producing powder by mutually rolling between grinding roller and bull ring, and this is the Cracking Mechanism place of abrasive dust main frame.
The charging aperture of flour mill main frame is opened on cover cylinder, the material entered from charging aperture is directly fall bottom main machine base from bull ring substantially, material rolls and mainly relies on relieving tool post drive perching knife rotate and complete between grinding roller and bull ring, and material is thrown between the grinding roller and bull ring of corresponding setting by described perching knife.
Because perching knife material casting angle is certain, and material is from fine sand to 4 centimetres of blocks not etc., light, heavy material movement locus is different, and quite a few aniseed is idle to fly away, and causes feeding not enough, is that this kind of flour mill yield in unit time is not high, the major reason of inefficiency.
(3) summary of the invention:
For this reason, the present invention proposes a kind of cross roll waterfall material flour mill, mainly solve the problem that traditional flour mill working (machining) efficiency is low.
