Description
Technical field
The present invention relates to a kind of material grinding system more particularly to a kind of integrate drying, selects powder and grinding function
Combined type cement grinding system and method suitable for high moisture material.
Background technique
In building materials industry especially cement grinding field, for ball mill although mill efficiency is low, the cement performance ground is it
What its milling equipment was difficult to substitute, so cement grinding system is most at present or uses ball mill or is made based on ball mill
Standby cement.In order to improve Ball Mill System yield, system grinding pow consumption is reduced, often taking reduces into ball mill material size
Method adds efficient grinding device before ball mill, and to add roll squeezer, outer circulation Vertical Mill etc., efficiently bed-grinding is equipped at present
It is main, it substantially increases system throughput, reduce system power consumption.But it is increasingly in short supply with resource, grind the retarder of cement with
Mixing material is gradually replaced industrial residue, and then the industrial residues such as desulfurized gypsum, metallurgical slag are widely applied.However mesh
For preceding many industrial residues based on wet row, moisture content is larger, and the synthesis moisture as cement raw material after cement raw material increases therewith
Add, the biggish moisture content of raw material can bring following problems:
(1) the pre- grinding equipment of bed-grinding does not adapt to high moisture material.
(2) the problems such as high moisture material enters ball mill, causes ball mill paste ball, paste mill, stifled comb seam, so that ball mill is not
It can operate normally.
(3) it when high-moisture retarder and mixing material participate in ingredient, is mixed on proportioning belt, in bucket elevator with clinker,
It will lead to part powdery clinker and shift to an earlier date aquation, reduce strength of cement, increase clinker proportion, increase production cost.
(4) when clinker temperature is higher, high moisture material is mixed with clinker, will lead to transmission process of the steam before entering mill
In be evaporated, dust-precipitator is entered together with fugitive dust, cause dust-precipitator paste bag.
It solves the problems, such as that the above high-moisture is brought, often takes the measure of drying, these high moisture materials are individually dried
After enter back into raw material storage or raw material cabin, this measure is although preferably reduce raw material moisture, so that Resolving probiems, but needs to consume
Heat consumption it is higher.Synchronous in the powder selection device of grinding system to realize drying and grinding, not only energy consumption is lower, can also play preferably
Drying effect, if but all materials prepared are directly fed into powder selection device with an ingredients belt, realize material
Powder is selected in first drying, and grinding is a good method again, but can substantially increase the specification of powder selection device, also increases and selects powder blower
Specification, and then increase system grinding pow consumption.
Furthermore often particle is thinner for industrial residue, it is fed directly into bed-grinding bed-grinding device, will lead to bed-grinding
The bad stability of equipment.
