The advantages that its product purity height, good dispersion, fine size and narrowly distributing, is especially welcome in crushing industry.
In the existing fluidized bed air flow crusher used, charging hole device will appear putty, sizing phenomenon often, seriously
Charging rate is influenced, if these sizings are handled not in time, the higher stain of adhesive strength can be formed in the inner wall of feeding device, this
A little stains can not only increase the cleaning difficulty of operating personnel, can also strong corrosion feeding device, reduce its service life.Meanwhile
Since material particular diameter is relatively thin, specific surface area is larger, and agglomeration easily occurs between material, enters in pulverizer in material
When, often along with big and small material group, these materials group is most of to scatter when head-on collision is broken, and remainder can hit
It is knocked material group that is closely knit, and then forming hard during hitting, slag-drip opening discharge is then fallen into due to that can not be crushed, in turn
Keep the crush efficiency of pulverizer relatively low, this be also restrict the restriction main factor that promotes and applies on a large scale of fluidized bed air flow crusher it
One.
It is still deposited in the material of slag-drip opening discharge in addition, the inlet plenum of existing pulverizer is all inlet duct of setting
In the material that part can be crushed, therefore, the crush efficiency needs of existing pulverizer further increase.
