Description
Technical field:
The present invention relates to a kind of recycling roller mill method of industry slag, particularly relate to one and fall with precompressed material and location
The vertical roll grinder of material and vertical roller grinder method.
Background technology:
Vertical roller grinder is a kind of important milling equipment in grinding technology field, it is desirable to be uniformly to be scattered to mill by material,
Grinding under the rolling of grinding roller.The problem that tradition slag micropowder production line project exists is mainly reflected in: 1, material is through chute
The cone mouth transporting material to inner cone along inner cone body wall falls to mill, and due to the existence of inertia, material departs from chute backlash
Hit the chute of lower straighttube just to inwall, then slight bounce-back drops down onto mill, i.e. material not drops down onto the center of mill, thus
Material dropping process inevitably isolates；2, material at inner cone lower straighttube in mill dropping process, a part
Material directly rushes at the place farther from mill center because lower straighttube can't stop, and the material of big is (in mixing material and grog
A part about 30mm granule can be there is) can be flushed to immediate vicinity from grinding roller, even it is directly entered grinding roller grinding district, and fine powder material
Then substantially drop down onto mill along lower straighttube inwall, isolate because of centrifugal force；3, grinding roller is because of material inequality cloth, and anon-normal occurs
Often abrasion, the problem causing the aspects such as yield is on the low side, power consumption is higher, injection flow rate is big, coal consumption is high.
It addition, Vertical Mill requires it is uniformly to be scattered to mill by material, grinding under the rolling of grinding roller.Solve material to exist
Can uniformly be scattered on mill and form the problem of the bed of material, be a key technology of Vertical Mill.Existing Stabilizing Materials bed device is main
Being water injector in mill, in mill, water spray can play the effect of the stable bed of material, but water can affect the chemical property of material, especially
When pulverizing cement, a part of cement can shift to an earlier date aquation, affects cement quality.
Summary of the invention:
The technical problem to be solved is: overcome the deficiencies in the prior art, it is provided that one is reasonable in design, discharging point is accurate
