Abstract

The invention discloses a crusher tooth roller. The crusher tooth roller comprises multiple roller shafts rotatingly installed in a crusher housing. Outer round surfaces of the multiple roller shafts are provided respectively with multiple axial grooves along a peripheral direction. Racks are inserted respectively in the multiple axial grooves. Each one of the racks comprises a strip-type boss. An upper surface of the strip-type boss is an arc surface. The arc surface is provided with multiple rows of cylindrical teeth connected into an integral body along a peripheral direction. A shearing blade is arranged along a peripheral direction between each adjacent two of the cylindrical teeth in each row, wherein the shearing blades are connected into an integral body. Multiple rows of the cylindrical teeth on an outer round surface of the rack corresponding to each adjacent two of the roller shafts are staggered. The shearing blade is arranged along a peripheral direction between each adjacent two of the cylindrical teeth in each row so that crushing efficiency and product fineness and uniformity are greatly improved, product grains have uniform sizes, energy consumption is low, production power is high, efficiency is high, operation is table, dust is less, and noise is small; and through rack insertion, a processing technology is simplified and installation, adjustment and maintenance are convenient.

Description

Cracker teeth roller

Technical field

The present invention relates generally to the disintegrating machine of mineral products fragmentation, relates in particular to toothed roll crusher, mainly is a kind of cracker teeth roller.

Background technology

Along with China's rapid development of economy, capital construction is in large scale.Demand to construction material will be surprising.China also is a mineral products demand big country simultaneously.The mineral products processing market prospects are wide.At present in China and even abroad, the broken process equipment of mineral products always in poor efficiency, high energy consumption, highly wear and tear, pace up and down in " one is low " of high pollution, " three height ".Such as " hammer mill ", " impact breaker ", be that match power is large, wear and tear in machines is large, efficient is low, noise is high, dust pollution is serious always.And still there is complex structure in old-fashioned " toothed roll crusher ", consumes that noble metal is many, maintenance cost is high, use defectives such as adjusting complexity, is difficult to apply always.The disintegrating apparatus of developing a kind of " high efficiency " " low energy consumption ", " low noise ", " dust pollution is little " has been extremely urgent.The patent No. is the toothed roll crusher patent of ZL201020628553.9, although solved the root problem of disintegrating machine, the manufacture craft more complicated, cost is higher.And do not have shear blade on the tooth bar of existing cracker teeth roller, thereby percentage of damage is relatively low.

Summary of the invention

The object of the invention is exactly in order to remedy the defective of prior art, provides that a kind of crushing efficiency is high, power consumption is low, noise is low, dust pollution is little, consumes that noble metal is few, equipment attrition is little, the cracker teeth roller of easy care simple in structure.

The present invention is achieved by the following technical solutions:

A kind of cracker teeth roller, include a plurality of roll shafts that are rotatably installed in the crusher shell, described a plurality of roll shaft is arranged side by side, it is characterized in that: be respectively equipped with in the circumferential direction of the circle a plurality of axial grooves on the periphery of described a plurality of roll shafts, be embedded with respectively tooth bar in described a plurality of axial groove, described tooth bar includes the bar shaped boss, the upper surface of described bar shaped boss is arc surface, have respectively in the circumferential direction of the circle many rows columnar tooth that one connects on the arc surface, have respectively in the circumferential direction of the circle the shear blade that one connects between the adjacent columnar tooth in every row's columnar tooth; In described a plurality of roll shaft, the many rows columnar tooth on adjacent two roll shafts on the corresponding tooth bar periphery staggers mutually.

Described a kind of cracker teeth roller is characterized in that: the bottom at each axial groove on the periphery of described a plurality of roll shafts is respectively equipped with a plurality of screwed holes along axis direction.

Described a kind of cracker teeth roller is characterized in that: be respectively equipped with a plurality of installing holes along axis direction on the exterior arc surface of described tooth bar.

Described a kind of cracker teeth roller is characterized in that: form in twos one group in described a plurality of roll shafts.

During use, power-on is slowed down and transmission device makes two roll shafts do to rotate in opposite directions.Add ore from top, columnar tooth and shear blade are carried out splitting and shearing-crushing to ore equably, and lump ore is broken into qualified particle.

The present invention has changed the structure of discaling roll in the prior art, and its purpose is: 1, be provided with in the circumferential direction of the circle shear blade between the adjacent columnar tooth in every row's columnar tooth, improved widely degree in small, broken bits and the uniformity of crushing efficiency and product; 2, be provided with in the circumferential direction of the circle a plurality of axial grooves on the roll shaft periphery, be embedded with respectively tooth bar in a plurality of axial grooves, simplified processing technology, reduced production cost; Made things convenient for simultaneously and installed and maintenance, time saving and energy saving.

Advantage of the present invention is:

Be provided with in the circumferential direction of the circle shear blade between the adjacent columnar tooth of the present invention in every row's columnar tooth, degree in small, broken bits and the uniformity of crushing efficiency and product have greatly been improved, can make the product seed even, energy consumption is low, production capacity is high, crushing efficiency is high, operate steadily, noise is little, dust is few; The setting-in of tooth bar has been simplified processing technology, installation, adjustment, easy to maintenance.
