Description
Technical field
The invention belongs to pulverizer manufacturing technology fields, and in particular to a kind of crushing part device for 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.Apply in crushing process
There are pressure rolling, shearing, impact (strike), four kinds of grinding in the external force of material.Pressure rolling be used primarily in it is thick, in it is broken, be suitable for hard material
With being crushed for bulk material；Shearing is used primarily in broken or crushes, the crushing suitable for toughness or fibroid material；It is main to impact (strike)
To be used in crushing and depolymerization, the crushing suitable for brittle material；Grinding mainly in ultra-fine grinding and ultramicro grinding, is suitable for middle fineness
Smashed ultramicro grinding.Existing pulverizer is mainly impact type breaking method, and such as previous utilizes free rolling metal ball
Crushing material is hit, or using the relative motion of the movable hammer body and surrounding fixed gear ring to run at high speed, makes material through hammer tooth punching
It hits, rub, impact and crushed to each other.Since impact type breaking method is needed to material repeated stock is hit, so powder
Broken inefficiency will such as cope with a large amount of crushing material operation, it is necessary to manufacture large-scale pulverizer.Since its impact object cannot
Selection, target is randomness, becomes the fine powder much smaller than target particles degree by the material of repeat impact, by number of shocks
Few is much larger than target particles degree, without having been impacted still.So prior art pulverizer always exists following lack
Fall into: first is that smashed material is not of uniform size, very unevenly, fine powder content is higher.But some fields require material particles uniform,
Such as plastics processing industry, it is desirable that plastic raw materials particle melts in unified temperature, because needing to melt when plastic shaping, particle
Small melt temperature is low, and particle the Nature needs higher temperature or time that could melt completely, so plastic raw materials particle is not
It is unfavorable for forming to it.The product of plastics petrochemical industry, plastics of the high molecular material after synthesizing are 0.2 to 20mm
The mixture of block not of uniform size and other liquid reagents, since current smashed particle is uneven, fine powder content compared with
Height needs before plastic shaping the granulation for carrying out similar extrusion molding to process, forms uniform plastic pellet.Prior art pulverizer
Defect second is that equipment land occupation is big and crush efficiency is low.
