CN205868395U - Novel breaker pair roller - Google Patents

Abstract

The utility model discloses a novel breaker pair roller, including roll body and ring tooth layer, the roll body is just cylindric it has penetrating shaft hole to open in the middle of the cylinder, and the annular ring tooth layer of circle passes through the bolt fastening on the roll body, the surface on ring tooth layer is equipped with the ring tooth who is made by wear -resistant material, the last interval of ring tooth is equipped with the breach, forms the tooth piece between two adjacent breachs, and a ring tooth's among two adjacent ring tooth tooth piece is adjacent with another ring tooth's breach, the tangent plane shape that the tooth piece is trapezoidal, this utility model reasonable in design, and broken work area is big, and crushing effect is good, and feeding, group material effect are showing, broken product granularity, particle shape qualification rate height.

Description

A kind of new type crushing machine is to roller

Technical field

This utility model belongs to crushing mechanism apparatus assembly technical field, particularly to a kind of new type crushing machine to roller.

Background technology

Breaker is applied the most widely in industry at present, life, and breaker is the most varied different, Current all kinds of breaker typically uses dynamic rotor and rotor mutually to roll broken principle and realizes crushing, and also has employing right Roller crushes, and the smooth mode to roller extruding that is roller of the most most double-roll crushers completes to crush, and this kind right There is the drawback that the roller pair breaking area of same diameter is little in the broken mode of roller, and smooth roll crushes the product grain of gained Shape is irregular, and defect ware is more, for this kind of problem applicant it has been suggested that cross the patent application of ring tooth design (2016202720209), before this application is compared, smooth round roller is relatively advanced, but the charging of this type of design, material toggling efficiency phase To poor.

Utility model content

Technical assignment of the present utility model is to provide a kind of new type crushing machine to roller for above prior art deficiency.

This utility model solve its technical problem be employed technical scheme comprise that a kind of new type crushing machine to roller, including roll body With ring tooth layer, described roll body is to have penetrating axis hole in the middle of cylindric and described cylinder, and circular ring tooth layer passes through spiral shell Bolt is fixed on roll body, and the outer surface of described ring tooth layer is provided with the ring tooth being made up of high-abrasive material, and described ring tooth is interval with Breach, the tooth block of a ring tooth in formation tooth block, and adjacent two ring teeth and another ring tooth between adjacent two breach Breach is adjacent.

Being further used as preferably, the cross-sectional shapes that described tooth block is is trapezoidal.

Further, use mode that collars tooth is mutually twisted to install and occlusion spacing between ring tooth be 2-10cm, The product of required different size is obtained to facilitate Producer can regulate the distance of ring between cog according to demand.

Originally it is that utility model provides the benefit that:

1, reasonable in design, simple in construction, easy for installation, it is simple to maintenance；

2, use collars tooth is designed and effectively increase broken area, effectively raise the crushing efficiency of disintegrating machine, And it is regular to the product particle shape that collars tooth is broken；

3, the design simultaneously using stagewise i.e. tooth block and breach on ring tooth adds the efficiency of charging, thus effectively carries High crushing efficiency.

Detailed description of the invention

With reference to Figure of description, workflow of the present utility model is described below:

As shown in Figure 1, Figure 2 and Figure 3, a kind of new type crushing machine is to roller, and including roll body 1 and ring tooth layer 2, described roll body 1 is Have penetrating axis hole 5 in the middle of cylindric and described cylinder, and circular ring tooth layer 2 is bolted on roll body 1, institute The outer surface stating ring tooth layer 2 is provided with the ring tooth 3 being made up of high-abrasive material, and described ring tooth 3 is interval with breach 4, adjacent two The tooth block 6 of a ring tooth 3 in tooth block 6, and adjacent two ring teeth 3 and breach 4 phase of another ring tooth 3 is formed between breach 4 Adjacent.

Being further used as preferably, the cross-sectional shapes that described tooth block 6 is is trapezoidal.

Claims (2)

1. new type crushing machine is to a roller, and including roll body (1) and ring tooth layer (2), described roll body (1) is cylindric and described cylinder Centre has penetrating axis hole (5), and circular ring tooth layer (2) is bolted on roll body (1), described ring tooth layer (2) outer surface is provided with the ring tooth (3) being made up of high-abrasive material, it is characterised in that: it is interval with breach on described ring tooth (3) (4), tooth block (6), and the tooth block (6) of a ring tooth (3) in adjacent two ring teeth (3) are formed between adjacent two breach (4) Adjacent with the breach (4) of another ring tooth (3).

A kind of new type crushing machine the most according to claim 1 is to roller, it is characterised in that: the tangent plane shape that described tooth block (6) is Shape is trapezoidal.
