Abstract

The utility model relates to a pendulum type crasher which can carry out fine crush for high quantity item on various materials of which the Mohs hardness is below grade seven. The utility model mainly comprises a casing which is provided with a feeding hole and a discharge hole, a rotor which is arranged in the casing and composed of a main shaft, a set of circular discs and a pendulum, and an annular lining board arranged between the pendulum and the casing. The upper half ring of the lining board is a grating screen which is composed of screen bars in gap arrangement, and the lower half ring is a corrugated sealing board which is composed of screen bars in gapless arrangement. When fed from the feeding hole, materials are impacted, extruded and ground by the pendulum and the annular lining board, and the crushed materials are discharged outside through the grating screen by wind force. The pendulum type crasher has the characteristics of high crushing efficiency and low energy consumption.

Description

Pendulum type machine for disintegration

The utility model relates to a kind of size reduction machinery, particularly a kind of suspended type pulverizer of the various materials of Mohs' hardness below seven grades being done the smart pulverizing of high-quantity item.

At present material is carried out fine powder meticulous pulverizing broken, particularly high-quantity item both at home and abroad, generally all adopt ball mill.Well-known, not only moulding is huge for ball mill, cost is high, and it is also higher to consume energy, and environmental pollution phenomenons such as noise, dust are very serious, and simply alternative with traditional pulverizer, crush efficiency is lower, and grinding particle size also is difficult to meet the demands.

In view of the foregoing, the purpose of this utility model provides that a kind of energy consumption is low, cost is low and crush efficiency is high, can make the smart suspended type pulverizer of pulverizing of high-quantity item to various materials.

The purpose of this utility model is achieved in that it comprises the casing that has charging aperture and discharging opening and places in the casing rotor that is made of main shaft, one group of disk and suspending hammer, be provided with highly abrasion-resistant and shock proof ring-type liner plate between suspending hammer in rotor mechanism and the casing, the last semi-ring that this liner plate and discharging opening are adjacent is the grate sieve that is made of the grating that discharge in the gap, and following semi-ring is the corrugated sealing plate that is made of the grating that discharge in no gap.When rotor mechanism is rotated at a high speed by driven by motor, under action of centrifugal force, suspending hammer outwards opens rapidly, material is from the charging aperture input, be subjected to the brute force impact of the suspending hammer of rotation at a high speed immediately, make material between suspending hammer and liner plate, be squeezed, grind and pulverize, the satisfactory material of grinding particle size according to wind-force through the sieve crack dispatch of grate sieve to discharging opening.

The utility model has the advantages that: liner plate and grate sieve is integrated, and liner plate is corrugated, thereby has improved crush efficiency greatly, compares with traditional size reduction machinery, and is under identical output situation, energy-conservation up to more than 60%.

The utility model is described in further detail below in conjunction with accompanying drawing.

Accompanying drawing is the utility model structural representation.

By accompanying drawing as can be known, the utility model comprises the casing 1 of top band discharging opening 8 and upper lateral part band charging aperture 7 and places in the casing rotor that is made of main shaft 3, a group of disk 4, suspending hammer 5 that (this rotor is identical with existing beater grinder structure, so do not draw in detail among the figure) and be located at the ring-type liner plate that constitutes one between casing and suspending hammer 5 ends by last semi-ring grate sieve 6 and following semi-ring corrugated sealing plate 2, last semi-ring grate sieve 6 is made of the grating of gap discharging, and following semi-ring corrugated sealing plate 2 is made of the grating of no gap discharging.

Claims

1, a kind of suspended type pulverizer, it comprises the casing that has charging aperture and discharging opening and places in the casing rotor that is made of main shaft, one group of disk and suspending hammer, it is characterized in that being provided with highly abrasion-resistant and shock proof ring-type liner plate between suspending hammer in rotor mechanism and the casing, the last semi-ring that this liner plate and discharging opening are adjacent is the grate sieve that is made of the grating that discharge in the gap, and following semi-ring is the corrugated sealing plate that is made of the grating that discharge in no gap.
