According to the utility model, the shearing edges are arranged between adjacent columnar teeth of each row of columnar teeth along the peripheral direction, so that the crushing efficiency and the fine crushing degree and uniformity of a product are greatly improved. The crusher tooth roller disclosed by the utility model has the advantages of uniformity in product grains, low energy consumption, high productive capacity, high efficiency, stability in operation, low noise and less dust, is simplified in the processing process through the embedment of the racks and achieves the convenience in installation, adjustment and maintenance.

Description

Cracker teeth roller

Technical field

The utility model relates generally to the disintegrating machine of mineral products fragmentation, relates in particular to toothed roll crusher, is mainly 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 is also 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, hover in " one is low " of high pollution, " three height ".As " hammer mill ", " impact breaker ", be that match power is large, wear and tear in machines is large, efficiency 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 defects such as adjusting complexity, be 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 toothed roll crusher patent that the patent No. is ZL201020628553.9, although solved the root problem of disintegrating machine, the manufacture craft more complicated, cost is higher.And there is no shear blade on the tooth bar of existing cracker teeth roller, thereby percentage of damage is relatively low.

The utility model content

The utility model purpose is exactly in order to make up the defect of prior art, provide a kind of crushing efficiency high, consume energy low, noise is low, dust pollution is little, consume that noble metal is few, equipment attrition is little, the cracker teeth roller of easy care simple in structure.

The utility model is achieved through the following technical solutions:

A kind of cracker teeth roller, include a plurality of roll shafts that are rotatably installed in crusher shell, described a plurality of roll shaft is arranged side by side, it is characterized in that: along the circumferential direction be respectively equipped with 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, along the circumferential direction there is respectively many rows columnar tooth that one connects on arc surface, along the circumferential direction there is respectively the shear blade that one connects in every row's columnar tooth between adjacent columnar tooth, in described a plurality of roll shaft, the many rows columnar tooth on adjacent two roll shafts on 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: on the exterior arc surface of described tooth bar, along axis direction, be respectively equipped with a plurality of installing holes.

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

During use, power-on, slow 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 to qualified particle.

The utility model has changed the structure of discaling roll in the prior art, and its purpose is: 1, between the adjacent columnar tooth in every row's columnar tooth, along the circumferential direction be provided with shear blade, improved widely degree in small, broken bits and the uniformity of crushing efficiency and product; 2, along the circumferential direction be provided with 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; Facilitated simultaneously and installed and maintenance, time saving and energy saving.

The utility model has the advantages that:

Along the circumferential direction be provided with shear blade between the adjacent columnar tooth of the utility model 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.
