Description
Technical field
The present invention relates to a kind of improved roller pulverizer.
Background technology
The crushing of material includes grinding and crushed, and is that the pulverized medium of material rolls crushing and reaches the purpose of crushing, leads to
Normal roller pulverizer is to be carried out using spring force principle come comminuting matter, this pulverizer using the mode of spring force roll-in
Comminution process, but be the problem of this pulverizer is present：Spring roller pressure can with the change of thickness when material is fed and
Change：That is spring elongation amount differs, and roller pressure will change therewith, when charging is few, equipment can not normal roll-in, if
Standby easily to produce idle running, so the operating efficiency of equipment straight line can also decline therewith, when a large amount of chargings, the amount of tension of spring is just
It can become big, caused roller pressure can not be fully completed crushing purpose with regard to small, at this moment also have by improving equipment, add pressure
Device on-load pressure carries out roll-in to reach the purpose of crushing to material again, but not only equipment cost is of a relatively high for this mode,
And its pressure loaded suddenly can produce very big impulsive force in itself to equipment, influence the normal use of equipment and reduce equipment
Service life.
Therefore, applicant is practical new in application number 201210446027.4, the China of entitled " a kind of roller pulverizer "
In type patent, a kind of roller pulverizer is disclosed, it includes rotating disk roller, driven disk roller and a drive device, the rotation
Disk roller and drive device drive connection, the rotating roller wheel are pressed on the driven disk roller；The rotation disk roller is equipped with
On the movable support body that one can swing up and down, the movable support body is movably connected on a fixed mount by a swinging axle.
The pulverizer of above-mentioned patent has the advantages that energy consumption is low, operating efficiency is high, simple structure, easy care.But apply
People when in use, has found two disk rollers of roller pulverizer in roll-in comminuting matter, because contacting with each other for two disk rollers is all
Carried out in a manner of oblique contact, two lateral wearings are few, and middle part abrasion is more, after friction roller is dynamic for a long time, form Fig. 7 and 8 knot
Structure, the operating efficiency of roller crushing is not only influenceed, and accelerate the abrasion of equipment.
In consideration of it, inventor is furtherd investigate again to above mentioned problem, there is this case generation then.
The content of the invention
Preferably material can be crushed it is an object of the invention to provide a kind of, improve service life of equipment and change
The roller pulverizer entered.
In order to achieve the above object, technical scheme as present invention use：
