Abstract

The utility model relates to a novel vertical compound crusher for crushing materials with medium hardness, which comprises a barrel body of the inner side is fixedly provided with a lining board. The upper and the lower ends of the barrel body are respectively provided with an upper cover and a pedestal, the lower end of a main spindle is fixed on the pedestal, and the upper end of the main spindle is fixed on a bracket. The upper half part of the main spindle is provided with an impact type rotor that is provided with a material distributing cone, the lower half part is provided with a hammer type rotor body that is provided with a tray, and the main spindle is driven by a motor to rotate through a belt. The utility model integrates the advantages of an impact type crusher, a vertical type crusher and a hammer type crusher and has the advantages of reasonable design, novel structure, high crushing efficiency, low energy consumption, high crushing ratio and low abrasion.

Description

Verticle compound crusher

The utility model relates to a kind of size reduction machinery, and a kind of being applicable to of saying so more specifically carried out broken NEW TYPE OF COMPOSITE standing crusher to medium hardness material (as lime stone, clinker etc.).

In the past, mostly use horizontal impact breaker, horizontal hammer mill etc.They all are to utilize beater plate or tup on the high speed rotor rotated body be fixed on the trunnion axis to hit material, discharge crusher chamber after making material reach certain fineness.Vertical impact formula disintegrating machine, vertical hammer mill and vertical impact crusher have appearred again in recent years, preceding two kinds of vertical types are compared with the horizontal type in past, and service behaviour has had improvement, and material is subjected to the repeatedly strike of rotor block from top to bottom, therefore, broken usefulness has had higher., the ratio of reduction is bigger, but because the rotor high-speed rotation, wearing and tearing such as rotor block, liner plate are more serious, and upper and lower inconsistent, and raw meal particle size is difficult for guaranteeing; And the vertical impact crusher of the latter is in recent years from external introduction, advanced disintegrating machine, it has cancelled rotor block, but utilize a rotor of the similar impeller shape of rotation at a high speed, make the material that enters rotor, under action of centrifugal force, thrown to cylinder inboard wall at a high speed, realize the collision of material and material, material and barrel, reach effective fragmentation, this disintegrating machine equipment is simple, does not have the part of strike, but because rotating speed height, the high-speed mobile of material in rotor makes the serious wear of rotor own, and the high installation requirement height of making of rotating speed.

The purpose of this utility model, a kind of NEW TYPE OF COMPOSITE standing crusher that designs in order to overcome the above-mentioned technical deficiency of two class disintegrating apparatus exactly.Promptly vertical impact and vertical hammer mill are combined, and suitably reduced rotating speed.Material is introduced into upper leaf colyliform rotor, realize with impact crusher in identical impact grinding, fall through material broken or that cracked, through the strike of the epitrochanterian tup of bottom hammer type, up to becoming fine grained discharge crusher chamber.

The utility model has been owing to reduced rotating speed, and rotor, to hit the part wearing and tearing not serious, and energy consumption is low, the material fragmentation that is hit earlier, after the fragmentation that overwhelms again, the ratio of reduction is big, can realize fine crushing.

The purpose of this utility model can realize in the following manner: a kind of NEW TYPE OF COMPOSITE standing crusher includes the hollow cylindrical cylindrical shell, its inside upper part is fixed with liner plate, the bottom is fixed with counterpunch board with press strip, there is the loam cake of band feeding pipe the upper end, the lower end is connected with the base of band hopper, main shaft lower end in the middle of the cylinder is fixed on the bearing arrangement of base central authorities, the upper shaft bearing apparatus is fixed on barrel by support, the main shaft first half is installed the impact shape rotor of impeller shape, the main shaft Lower Half is installed the rotor block identical with hammer mill, the both is keyed on the main shaft, main shaft lower end extension is equipped with belt pulley, by belt by the motor drives main axis rotation.

The utlity model has following advantage: material is subjected to the effect of two kinds of multi-form crushing forces, has realized that the ratio of reduction is big than the fragmentation under low speed, the low energy consumption, epigranular; Parts depreciation is little.

Accompanying drawing is the utility model " novel combined disintegrating machine " structural representation.

The utility model embodiment can be further specified in conjunction with Figure of description.

After material enters from feeding mouth 1, fall on the material distributing cone 3 by loam cake 2 interstitial holes, be sprinkled into uniformly in the impact type rotor 4 of similar draught fan impeller, because the rotation of main shaft, material throws away after being accelerated in rotor, impact on the liner plate 5 that is fixed on the cylinder 6, be collided, (material also have the collision effect mutually) such as wearing and tearing, raw meal particle size is reduced, and then, material drops on the pallet 8 of bottom, same because action of centrifugal force, material is dished out or directly fallen into hammer hits the district, is subjected to hanging over the repeatedly strike of the tup 9 on the rotor block 10, grind, granularity is constantly reduced.

At last, the material that is broken is discharged by the bottom end cover 13 and the discharge gate 15 of hollow.Main shaft 11 has metal (

upper device

7 and 12 to fix, and passes through belt pulley 14 by motor 16 driven rotary.

Claims

A kind of NEW TYPE OF COMPOSITE standing crusher that is used for comminuting matter, partly constitute by charging aperture, cylindrical shell, liner plate, material distributing cone, impact type vane rotor, rotor of hammer type crusher, discharging opening, main shaft device, motor etc., it is characterized in that: main shaft the first half is equipped with the impact type vane rotor, Lower Half is equipped with rotor of hammer type crusher, and both form a compound rotor block.
