Abstract

Disclosed is a screening and pulverizing linkage machine, in particular to a pulverizer which can screen to raw materials. The processes of screening and pulverizing are integrated. Firstly, the pulverized raw materials are screened; the raw materials with satisfactory granularity are separated; then the rest raw materials are pulverized. The utility model has the advantages of small size, energy consumption saving, long service life, etc.

Description

Screening and pulverizing linkage machine

The utility model relates to a kind of pulverizer, particularly a kind of pulverizer that can carry out prescreen to raw material.Be applicable to the pulverizing of medium hardness fragile material, be particularly useful for pulverizing coal.

With regard to prior art, screening and pulverizing are normally carried out step by step by different machines.Because the function singleness of machine, screen at needs, must be equipped with corresponding machine when pulverizing and achieve the goal.Therefore make that energy consumption increases, investment increases.When for example producing honeycomb briquette or coal briquette in the coal processing industry, coal need be processed into the coal dust of granularity less than 3mm, and in the raw coal general existing partly granularity less than 3mm, for the granularity of the raw coal existing about 50% of mechanized extraction less than 3mm.Therefore raw coal needed before pulverizing through screening, so just made that plant investment increases, power consumption increases.

The purpose of this utility model will provide a kind of screening to pulverize gear exactly, will screen, crushing process is integrated.Pulverized raw material is carried out prescreen earlier, the satisfactory raw material of granularity is separated earlier, remaining raw material is pulverized again.Be implemented in and enhance productivity, reduce energy consumption under the condition that does not increase equipment.

Below by embodiment, in conjunction with the accompanying drawings the utility model is further described.

Figure one is the utility model cross-sectional schematic.

Figure two is figure one an A-A profile.

1 is support assembly among the figure, and 2 is motor, and 3 are pulverizer ring hammer assembly, and 4 are the pulverizer sieve.Establish separating sieve 5 above pulverizer feed(raw material)inlet place, separating sieve 5 links to each other with body by elastomeric material, and elastomeric material can be with materials such as steel discs.The course of work of the utility model embodiment is such: the vibrations during pulverizer work drive separating sieve 5 vibrations, and raw material adds the fashionable separating sieve 5 that passes through vibrations by sorting, and clout enters pulverizer and pulverizes.

Straight what must propose is that separating sieve of the present utility model, crusher sifting are to adopt the movable bar grizzl(e)y of deformed steel, and grating can exchange, and has so just greatly improved the whole life-span of grating.

The utlity model has the characteristics such as volume is little, power consumption economizes, the life-span is long.

Claims

1, gear is pulverized in screening, comprises support assembly, pulverizer ring hammer assembly, pulverizer sieve, it is characterized in that: establish separating sieve above place, pulverizer feed(raw material)inlet.

2, machine as claimed in claim 1 is characterized in that separating sieve links to each other with body by steel disc.

3, machine as claimed in claim 1 is characterized in that separating sieve, pulverizer sieve are to adopt the movable bar grizzl(e)y of deformed steel.
