Abstract

The utility model relates to a vertical combined crusher for crushing materials with medium rigidity, comprising a barrel body. Lining boards and counterpunch boards are fixed at the inner side of the barrel body, and the counterpunch boards are fixed by pressing strips. The upper and lower two ends of the barrel body is 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 is fixed on a bracket. The upper part of the main spindle is provided with impact rotors that have distribution cones, and the lower part is provided with counterpunch rotors that have trays. The main spindle is driven to rotate by an electric motor through belts. The utility model integrates the advantages of impact crushers and vertical counterpunch crushers and has reasonable design, novel structure, high efficiency, low energy consumption, high crushing rate and low abrasion.

Description

Vertical combined 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 novel combined vertical disintegrating machine to medium hardness material (as lime stone, clinker etc.).

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 that is fixed on the trunnion axis to hit material, discharge crusher chamber after making material reach certain fineness, vertical impact formula disintegrating machine has appearred again in recent years, vertical hammer mill and vertical impact crusher, preceding two kinds of vertical types are compared with the horizontal type in past, service behaviour has had improvement, material is subjected to the repeatedly strike of rotor block from top to bottom, therefore, broken usefulness has had higher, and the ratio of reduction is bigger, but because rotor high-speed rotation, rotor block, wearing and tearing such as liner plate are more serious, and on, inconsistent down, 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 novel combined vertical disintegrating machine that designs in order to overcome the above-mentioned technical deficiency of two class disintegrating apparatus exactly.Promptly vertical impact and vertical impact formula disintegrating machine are combined, and suitably reduce 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 fragmentation of strike repeatedly of epitrochanterian beater plate of bottom counterattack type and counterpunch board, discharge crusher chamber up to becoming fine grained.

The utlity model has following advantage: object is subjected to the effect of two kinds of multi-form crushing forces, has realized that parts depreciation is little than the fragmentation under low speed, the low energy consumption, and 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 novel combined vertical disintegrating machine 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 stepped rotor block identical with impact breaker, 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.

Accompanying drawing is the utility model " novel combination type disintegrating machine " structural scheme of mechanism.

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, then, material drops on the pallet 8 of bottom, and is same because action of centrifugal force, material is dished out or is directly fallen between the beater plate 9 and counterpunch board 10 on the stepped reaction type rotor 18, be subjected to hitting repeatedly and strikeing back, wash away, grind, granularity is constantly reduced, counterpunch board is fixed on the barrel with press strip 11, press strip simultaneously plays a part also to prevent that bulk materials from directly falling discharging opening, at last, the material that is broken is discharged by the bottom end cover 14 and the discharge gate 16 of hollow, main shaft 12 has metal (upper device 7 and 13 to fix, and passes through belt pulley 15 by motor 17 driven rotary.

Claims

A kind of novel combined vertical disintegrating machine that is used for comminuting matter, partly constitute by charging aperture, cylindrical shell, liner plate, material distributing cone, impact type vane rotor, reaction type rotor, counterpunch board, discharging opening, main shaft device, motor etc., it is characterized in that: the vertical main shaft device of installing in the cylindrical shell, the main shaft first half is the impact type vane rotor fixedly, Lower Half fixedly is equipped with the reaction type rotor of beater plate, and both form a combined rotor block.
