Description
Technical field
The present invention relates to ore processing technical fields more particularly to a kind of processing of mine rock material to use Highefficientpulverizer.
Background technique
Pulverizer is the machinery that large-sized solid material is crushed to desired size, and pulverizer is by coarse crushing, fine crushing, wind-force
The devices such as conveying composition, the purpose of pulverizer is reached in the form of high-speed impact, using wind energy once at powder, is eliminated traditional
Screening sequence, the building stones processing pulverizer of ore are the devices to building stones into crushing, and building stones are needed by just can be carried out after crushing
Connect it is lower in processing pulverizer classification according to by particle or it is broken system material size Highefficientpulverizer can be divided into boulder crusher, in it is broken
Machine, atomizer mill, ultra-fine grinding mill.The external force that solid is applied in crushing process has pressure rolling, cutting, impact, four kinds of grinding.Pressure rolling
Be used primarily in it is thick, in it is broken, suitable for the broken of hard material and bulk material；Cutting is used primarily in powder fine crushing, suitable for toughness material
It is broken；Impact broken, fine grinding, Ultrafine Grinding in being used primarily in, the crushing suitable for brittle material；Grinding is suitable for mainly in fine grinding, Ultrafine Grinding
Fritter and fine grain crushing.Pulverizer can be used in different fields by the difference of model, and boulder crusher is mainly used for each row
The material 5-10cm being relatively large in diameter mainly is machined to the lesser granular substance of diameter by its effect of the comminution pretreatment operation of industry
Material diameter is 5-10mm.It is by granular materiel machining that pulverizer, which is mainly used for the middle finess disintegrating operation of every profession and trade its effect,
To need the middle fineness powder of diameter to carry out subsequent processing or as finished product.Micronizer is mainly used for major part
The ultramicro grinding operation of industry is crushed the material after comminution process again to reach the material diameter of needs and be mainly used for height
The raw material processing of product is held, large-scale pulverizer is primarily adapted for use in smelting with the higher equipment of yield under the premise of identical smashing fineness
The crushing of the industries mineral products material such as gold, building materials, chemical industry, mine, expressway construction, water conservancy and hydropower, refractory material, steel adds
Work.Micromill with the lower equipment of yield under the premise of identical smashing fineness be primarily adapted for use in food, chemical industry, medicine, greening,
Environmental sanitation, etc. industries crushing material processing.
In the building stones processing in mine, it would be desirable to use stone crusher, carry out powder to building stones by stone crusher
After broken, then smashed building stones are processed, but existing frequently-used stone crusher is all poor for the crushing effect of building stones
Seldom, appearance to be achieved is thought it cannot be guaranteed that being very ground into, so to screen to smashed building stones, after screening again
Secondary to be rolled, the sieve for being more troublesome, the efficiency of significantly lower work, and generally being screened in this way can make without cleaning
Mesh blocking is obtained, is not easy to use next time.
So not high in order to solve existing pulverizer working efficiency, and screen fraction it is unclear for a long time comprehend influence dress
