Abstract
The utility model discloses a non-blocking sieving crusher and includes a crusher shell which is provided with a discharge port and a feed port. The non-blocking sieving crusher also includes a first sieving device erected on the crusher shell and arranged between the feed port and the crusher, and a second sieving device erected on the crusher shell and arranged between the discharge port and the crusher; both the first sieving device and the second sieving device are formed by a plurality of rotating sieving shafts. Materials entering from the feed port are primarily sieved by the first sieving device firstly through the first sieving device and the second sieving device of the non-blocking sieving crusher, which avoids the generation of over-crushing. As both the first sieving device and the second sieving device are formed by a plurality of rotating sieving shafts, and the gaps of each rotating sieving shaft are adopted as sieve pores, and the rotating sieving shafts are all rotatable, crushed materials can not be blocked in the gaps, thus effectively solving sieving material distribution and improving the sieving efficiency.
Description
Technical field
The utility model relates to the disintegrating machine technical field, and more particularly, relating to a kind of sub-sieve does not have stifled disintegrating machine.
Background technology
Disintegrating machine extensively applies to numerous departments such as mine, smelting, building materials, highway, railway, water conservancy and chemical industry.Disintegrating machine at present commonly used has ring hammer disintegrating machine, toothed roll crusher and tup formula disintegrating machine.
The broken sieve plate of ring hammer disintegrating machine is hole or bar pass, and when material entered the cracking cabin fragmentation, the sieve plate hole was stopped up by material, and particle size after cracking can't be got rid of, inner one-tenth plate, integrated in a large number.Rotor is subjected to running up of main motor, and epitrochanterian ring is hammered into shape directly and material hardens rubs, and accelerates the wearing and tearing of ring hammer.The ring hammer is in case wearing and tearing; broken gap increases; cause particle size after cracking not reach requirement, the sieve aperture of sieve plate can only be turned down, the too small meeting of the sieve aperture of sieve plate makes inlet amount big; load is little; cause inside can't discharge effective size of grain, cross fragmentation seriously, cause disintegrating machine to stop up; stuck, cleared up by forced-stopping machine at last.
Toothed roll crusher: the tooth depth on two discaling rolls adopts the squeeze function fragmentation in 10mm, gangue, and the fragmentation of high-moisture materials such as coal slime, the tooth depth wearing and tearing are quite fast, friction reduces in case tooth is worn.Coal slime, the high moisture material flowability is little, causes two discaling rolls to skid, the charging aperture arch camber, coal spout is forced to stop up, and gangue enters fragmentation, and spoil hardness is made a concession two discaling rolls simultaneously, and the material all-in and all-out adds the wearing and tearing of tooth, can't guarantee granularity.
Tup formula disintegrating machine: tup is a rectangle, and the plane of disruption is on two right angles, and the wearing and tearing at angle are quite fast, and crushing shell can't discharge, and the collection of materials inside is pressed, and the tup enhance faster wear can't guarantee granularity.In order to guarantee that granularity can only regulate crushing shell, effective size of grain also can't be discharged in inside, causes broken phenomenon serious.
In sum, nowadays need a kind of disintegrating machine that can avoid broken and prevent to stop up badly.
The utility model content
In view of this, the utility model provides a kind of sub-sieve not have stifled disintegrating machine, with the generation of avoiding broken phenomenon with prevent that sieve plate from stopping up.
