Description
Technical field
The invention belongs to pulverizer manufacturing technology fields, and in particular to a kind of coal slurry pulverizer.
Background technique
Pulverizer is the machinery that large-sized solid material is crushed to desired size, the general solid-liquid mixing of when crushing,
The fields such as chemical industry, metallurgy, plastics, food, pharmacy, building are widely used.Boulder crusher is mainly used for the comminution pretreatment of every profession and trade
Operation, effect is mainly by the materiel machining being relatively large in diameter to the lesser granular material of diameter.
China is producing coal and coal chemical industry big country, first will be to its comminution pretreatment operation when raw coal is as coal chemical industry raw material.Powder
Raw coal need to be mixed with water when broken, referred to as coal slurry, also referred to as water-coal-slurry.Ideal state is to be ground into particle outer diameter to be
The uniform coal particle of 0.5mm or so.Existing coal slurry pulverizer is mainly impact type breaking method, and such as previous utilizing freely rolls
Metal ball hit crushing material, or using the relative motion of movable hammer body and surrounding fixed gear ring to run at high speed, make material
It is collided through hammer tooth, friction, impacts and crushed to each other.Since impact type breaking method needs to rush shock material repeatedly
It hits, so crush efficiency is low, such as to cope with a large amount of crushing material operation, it is necessary to manufacture large-scale pulverizer.Due to its punching
Hitting object cannot select, and target is randomness, become the fine powder much smaller than target particles degree by the material of repeat impact,
By number of shocks it is few be much larger than target particles degree, without having been impacted still.So prior art pulverizer is always
Have following defects that very unevenly, fine powder content is higher first is that smashed material is not of uniform size；Defect is second is that equipment is taken up an area
