Abstract

The utility model relates to a hammer crusher which mainly comprises a casing, lining boards and the main spindle thereof, a circular disc, a pin shaft, and a rotor, wherein, the upper part of the casing has a feed inlet, the lower part of the casing has a discharge outlet, and the rotor is composed of hammers. The inner part of the lining board is directly communicated with the feed inlet, and the grid sieve of a discharge channel is installed between the casing and the outer part of the lining board, which integrates the sieve and the lining board so that materials can be exhausted out of a crushing cavity when once crushed. The utility model, therefore, avoids the phenomena of over crushing, relatively increase the efficiency of crushing, and simultaneously reduces energy consumption.

Description

Hammer type disintegrating machine

The utility model relates to a kind of size reduction machinery, particularly a kind of hammer mill.

The hammer crushing acc power of widespread usage is bigger at present, on the discharge function, only establishes 400-600 millimeter rectangle grating passage below rotor, and other position can not discharge.Cause in the material brokenly to meet granularity requirements or the former material that has met granularity requirements grinds with treating that broken material is piled up in to charge and attack repeatedly in the crushing chamber to squeeze, not only influence crush efficiency, and waste energy, it is very serious to cross crushing phenomenon.

In view of the foregoing, the purpose of this utility model provides a kind of hammer mill of avoiding crushing phenomenon, cut down the consumption of energy and improving crush efficiency.

The purpose of this utility model is achieved in that it comprises that mainly top has the rotor that charging aperture, bottom have the casing of discharging opening and place the liner plate in the casing and is made up of main shaft, disk, bearing pin, tup, and its technical essential is: directly communicate with charging aperture in this liner plate is, outward and the annular grate of establishing discharging channel between casing sieve.It is full annular grate sieve double as liner plate, when material when the top charging aperture drops into, the tup that is subjected to rotation at a high speed immediately hits and impact, high strength and wear-resisting annular grate sieve are brought into play the liner plate effect of holding concurrently of its grating this moment, make material be subjected to beating, dash, press the synergy of grinding and pulverized, discharge through the sieve crack less than the grade in annular grate sieve sieve crack in the material, and pour into discharging opening by discharging channel.And greater than the sieve crack the coarse fraction material still detention in crushing chamber, continue to catch a packet, until by the sieve crack till.

The utility model is owing to make annular grate sieve with whole liner plate in the casing, be sieve and liner plate collection the whole body, material can be discharged outside the crushing chamber once fragmentation, thereby avoided crossing crushing phenomenon, simultaneously relatively also improved crush efficiency, energy-conservation up to more than 60% under identical output situation.

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

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is the left side view of Fig. 1.

By accompanying drawing as can be known, the annular grate sieve 8 that the utility model comprises the casing 6 that has charging aperture 1 and discharging opening 7 and the rotor that is made of main shaft 5, disk 3, tup 2 and bearing pin 4 and double as liner plate are used, broken main body tup is contained on the bearing pin between each disk in hinged way, make it and on bearing pin, to swing, the annular grate sieves 8 inner chambers and directly communicates with charging aperture 1 from its indentation, there, the crack is a discharging channel 9 between annular grate sieve 8 outsides and the casing 6, and this discharging channel communicates with discharging opening 7.

Claims

1, a kind of hammer mill, it mainly comprise top have charging aperture, bottom have the casing of discharging opening and place in the casing liner plate and by the rotor that main shaft, disk, bearing pin, tup are formed, it is characterized in that: directly communicate with charging aperture in this liner plate is, outward and the annular grate of establishing discharging channel between casing sieve.
