Description
Technical field
The present invention relates to a kind of sorting unit, belongs to cement processing technique field.
Background technology
The grinding of solid material is widely used in the production process of cement, slag, nonmetallic ore, is needed in grinding process
To timely being sorted by the material of grinding, material otherwise just easily occur crosses grinding phenomenon.
Existing sorting unit once sub-elects the maximum bulky grain of diameter and the middle particle being relatively large in diameter, and diameter is less
Particle is collected as finished product, and the efficiency that this sorting mode sorts is low, once sorts away bulky grain and middle particle, is sorting
In there is more little particle to be swept along by bulky grain and middle particle, return grinding system, cause material to cross grinding phenomenon, enable grinding
Consumption increase, while also result in yield reduction.
The content of the invention
The present invention relates to a kind of sorting unit, solve the sorting unit efficiency of separation of the prior art and sub-elect into
The technological deficiency that product material yields poorly.
