Abstract

The invention discloses a selective crusher. The selective crusher comprises a body, wherein the body is provided with a feed hole; a unit movable tooth roller which can move and a fixed tooth roller which is fixedly arranged on the body are correspondingly arranged between the feed hole and a discharge hole in the lower side; the unit movable tooth roller is connected with an adjustable pressure spring set; the pressure of the unit movable tooth roller can be adjusted by the adjustable pressure spring set; the fixed tooth roller is connected with fixed roller motors; the fixed roller motors are arranged on the two sides of the body; the fixed tooth roller is driven by the fixed roller motors to rotate. The selective crusher has the beneficial effects that a mechanical device capable of selectively crushing the material is provided and the crushing efficiency is improved.

Description

A kind of bradford breaker
Technical field
The invention belongs to mechanical equipment technical field, relate to a kind of bradford breaker.
Background technology
Coal resources in China enriches, and coal is complete, but distribution of coal sorts ratio differs greatly, its quantity and distributed pole imbalance, and in the coal resources that China is abundant, the main coking coal such as coking coal, rich coal, lean coal is rare.The middle coal of current Chinese coking coal coal preparation plant almost all uses as fuel, and this is undoubtedly the significant wastage to Chinese scarce coal resources.Middle coal is the byproduct in coal preparation process, the cleaned coal that has been various coal preparation technique enriching and recovering and discharge the later intermediate products of tail coal.Its basic characteristics are all high relative to minerals in coal raw coal, sulfur content, and calorific value is lower.Due to these reasons, cause the product price of middle coal low more than cleaned coal.Therefore, how therefrom research reclaim head coal product, the utilization rate of coal in raising in coal to greatest extent, is reduce coal separation production cost, improves profit, the effective way of economize energy.And the meaning that selective crushing equipment selects for middle coal is again, supplied materials carries out selective crushing, realizes dissociating of coal and spoil, the spoil that not broken hardness is high again simultaneously, thus reduces energy consumption, saves broken cost.
Summary of the invention
The object of the present invention is to provide a kind of bradford breaker, need to carry out sorting when solving the fragmentation of existing different material, the problem that crushing efficiency is low.
The technical solution adopted in the present invention comprises body, body is provided with feeding mouth, between feeding mouth and the discharge gate of below, corresponding being provided with can movable unit activity discaling roll and the fixing discaling roll that is fixed on body, unit activity discaling roll connects adjustable compression spring group, adjustable compression spring group can regulate the pressure to unit activity discaling roll, fixing discaling roll is connected and fixed roller motor, and stationary roll motor is arranged on body both sides, and fixing discaling roll is rotated by stationary roll driven by motor.
The invention has the beneficial effects as follows to provide and a kind ofly to the mechanical device of material selective crushing, crushing efficiency can be improve.
Accompanying drawing explanation
Fig. 1 is disintegrating apparatus structural representation of the present invention;
Fig. 2 is disintegrating apparatus top view of the present invention.
In figure: 1-body, the adjustable compression spring group of 2-, 3-feeding mouth, 4-unit activity discaling roll, 5-stationary roll, 6-discharge gate, 7-fixed teeth roller motor.
Detailed description of the invention
Below in conjunction with detailed description of the invention, the present invention is described in detail.
Bradford breaker of the present invention as depicted in figs. 1 and 2, comprise body 1, body 1 is provided with feeding mouth 3, between the discharge gate 6 of feeding mouth 3 and below corresponding be provided with can be movable unit activity discaling roll 4 and the fixing discaling roll 5 that is fixed on body 1, unit activity discaling roll 4 connects adjustable compression spring group 2, adjustable compression spring group 2 can regulate the pressure to unit activity discaling roll 4, fixing discaling roll 5 is connected and fixed roller motor 7, stationary roll motor 7 is arranged on body 1 both sides, and fixing discaling roll 5 drives rotation by stationary roll motor 7.
The present invention, according to the nonhomogeneous hardness between different ore, carries out selective crushing, realizes soft fragmentation, the chip-proof shattering process of high rigidity.During use, material enters bradford breaker by feeding mouth 3, fixing discaling roll 5 is driven to rotate by stationary roll motor 7, by the extruding between fixing discaling roll 5 and unit activity discaling roll 4, produce the extruding slabbing action power moving downward direction, material rotates with discaling roll and is brought between fracture area, difference according to material hardness carries out selective crushing, extruding force between discaling roll is less than adjustable pressure groups of springs 2 when being out of shape stressed, material is broken by discaling roll, otherwise unit activity roller 4 is out of shape by express material power generation transverse shifting compression adjustable pressure groups of springs 2, broken bore is made to become large thus material passes through, material discharges body 1 eventually through discharge gate 6.The size of fixing extruding force between discaling roll 5 and unit activity discaling roll 4 can realize controlling to adjust by changing adjustable pressure groups of springs 2, thus realizes the material that only broken hardness is low, the object of the material that not broken hardness is high.This equipment has used attrition crushing principle and spring stress deformation principle, is a kind of selective crushing equipment.
The present invention be advantageous in that: according to energy ezpenditure principle, shattering process is an energy consumption process, and therefore reducing unnecessary comminution energy conssumption is as much as possible the problem that reduction energy consumption should be considered.Bradford breaker does not carry out fragmentation for high rigidity material, only broken soft material, and hardness height is here for the nonhomogeneous hardness between mineral.Thus under the condition realizing mutually dissociating between different minerals, reduce energy consumption this purpose as much as possible, and reduce production and operation cost.
The above is only to better embodiment of the present invention, not any pro forma restriction is done to the present invention, every any simple modification done above embodiment according to technical spirit of the present invention, equivalent variations and modification, all belong in the scope of technical solution of the present invention.
