Abstract
The invention discloses a kind of new selectives to be crushed double-geared roller crusher, is made of casing and crushing device, and crushing device is made of several groups breaker roll facing each other, and crushing teeth is connected by spring with the inner layer surface of breaker roll；The spring of connection crushing teeth and breaker roll inner layer surface, equipped with a series, can replace the springs of different-stiffness according to rigidity difference according to the difference of spoil hardness.Crushing teeth can carry out selective crushing to material according to the size of material hardness in shattering process, and reduction is crushed the higher material of hardness, while the spring of different-stiffness is replaced according to the property of material, improves crushing efficiency.
Description
Technical field:
The present invention relates to broken mill machinery, in particular to a kind of selective crushing double-geared roller crusher.
Background technique:
Double-geared roller crusher is suitable for the industries such as sinter, coal, cement, silicate, glass, ceramics, is suitable for medium hard
Being crushed for brittle material below spending, is mainly used for operation fine crushing in ore.Compared with other kinds of crusher, double teeth roller is broken
Broken machine has many advantages, such as that structure is simple, and crushing phenomenon is few excessively, reliable operation, work efficiency is high, but in the broken of coal preparation plant's coal
In, since double-geared roller crusher is without selectivity, the spoil in coal is caused to be broken and be entrained in coal together, for after coal
Continuous sorting brings trouble.
Summary of the invention:
Technical problem: passing through selective crushing in coal separation, and the harder substance such as spoil is broken in reduction coal.
Technical solution: new selective is crushed double-geared roller crusher, is made of casing and crushing device, if crushing device by
Dry group breaker roll composition facing each other, belt pulley are connected with rotary shaft, and rotary shaft is connected with breaker roll；Each breaker roll is by interior
Level and outer layer surface composition, crushing teeth are connected by spring with the inner layer surface of breaker roll；The outer layer surface of breaker roll is provided with and is crushed
The aperture that tooth size is mutually agreed with, crushing teeth exposes breaker roll outer layer surface by aperture, and is only done straight line side by the constraint in aperture
To movement；There is feeding inlet on casing top, bottom of shell has discharge port.
The spring of crushing teeth and breaker roll inner layer surface is connected according to rigidity difference equipped with a series, it can be according to spoil
The spring of the different replacement different-stiffness of hardness.
The utility model has the advantages that crushing teeth can carry out selective break to material according to the size of material hardness in shattering process
Broken, reduction is crushed the higher material of hardness, while the spring of different-stiffness is replaced according to the property of material, improves broken effect
Rate.
Detailed description of the invention:
Fig. 1 is main view of the invention；
Fig. 2 is side view of the invention.
In figure: 1- crushing teeth, 2- spring, 3- outer layer surface, 4- inner layer surface, 5- rotary shaft, 6- feeding inlet, 7- discharge port, 8-
Casing, 9- belt pulley, 10- breaker roll.
Specific embodiment:
Implementation of the invention is further described with reference to the accompanying drawing:
With reference to the accompanying drawings 1 and attached drawing 2 shown in, new selective is crushed double-geared roller crusher, by casing 8 and crushing device group
At crushing device is made of several groups breaker roll 10 facing each other, and belt pulley 9 is connected with rotary shaft 5, rotary shaft 5 and broken
Roller 10 is connected；Each breaker roll 10 is made of inner layer surface 4 and outer layer surface 3, and crushing teeth 1 passes through the internal layer of spring 2 and breaker roll 10
Face 4 is connected；The outer layer surface 3 of breaker roll 10 is provided with the aperture mutually agreed with 1 size of crushing teeth, and crushing teeth 1 is exposed broken by aperture
The outer layer surface 3 of broken roller 10, and only done by the constraint in aperture the movement of rectilinear direction；There are feeding inlet 6, casing 8 on 8 top of casing
Discharge port 7 is arranged at bottom.
The spring 2 of crushing teeth 1 and breaker roll inner layer surface 4 is connected according to rigidity difference equipped with a series, it can basis
The spring 2 of the different replacement different-stiffness of spoil hardness.
Material is fed by feeding inlet 6, and motor drives belt pulley 9 to rotate, and belt pulley drives rotary shaft 5 to rotate and then drives broken
The rotation of broken roller, crushing teeth 1 are crushed material, and when encountering the higher material of hardness, spring 2 is compressed, and crushing teeth is downward
Length reduction that is mobile and making its exposing breaker roll outer layer surface 3, is crushed high rigidity material to reduce, and breakdown products are from out
Material mouth 7 is discharged.
Working principle: making crushing teeth be connected with spring, is subjected to displacement crushing teeth by the deformation of spring, changes crushing teeth
Expose the height of breaker roll outer layer surface, spring is compressed when encountering harder material, is crushed movement inside teeth directional breaker roll, is made
The distance between itself and another breaker roll outer layer surface increase, to reduce the broken of high rigidity material.The spring shape of different-stiffness
Variable is different, can preferably adapt to the property of material.
