Description

A kind of spoil pulverizer

Technical field

The utility model belongs to field of mechanical technique, relates in particular to a kind of spoil pulverizer.

Background technology

The raw coal that exploitation is come out from the colliery need be reprocessed into the fragment into certain particle size, produces many times to rely on manpower to solve in the past, pounds coal, inefficiency by hand.Plant equipment has appearred in development afterwards, but when the pulverizer on the existing market used, the wearing and tearing of drum screen and tup were very serious, need often replacing, and machine often stops up, and need manually dredge, and has reduced efficiency.

The utility model content

In order to overcome disadvantages of background technology, the utility model provide a kind of simple in structure, the ratio of reduction is big, use cost is cheap, the power consumption is little, long service life, be difficult for stopping up, spoil pulverizer that production efficiency is high.

For achieving the above object, the technical solution adopted in the utility model is as follows:

A kind of spoil pulverizer, comprise housing, feeding mouth, crushing shell, sieve plate, discharging opening, adjusting bolt, foreign matter collecting chamber, rotor, tup, described feeding mouth is located at the housing upper end, discharging opening is located at the housing lower end, crushing shell, sieve plate, foreign matter collecting chamber, rotor, tup are located at enclosure interior, regulate bolt and be located at the housing side, tup is located at two ends of rotor.

Described feeding mouth is the rectangle of 1000mm * 300mm.

Described root diameter is 1000mm.

After material enters feeding mouth, be subjected to the fragmentation with the percussion of the tup of rotor high-speed rotation, the material that is broken obtains kinetic energy simultaneously outside tup, rush at crushing shell at a high speed.After being subjected to fragmentation for the second time, fall on the sieve plate, shearing, extruding, grinding and the material and the interaction between the material that are subjected to tup are further broken, and discharge by discharging opening.Can not then enter the foreign matter collecting chamber by broken foreign matter, regularly remove.

Of the present utility model have beneficial effect to be: the spoil mill structure that the utility model provides is simple, the ratio of reduction is big, use cost is cheap, little, the long service life of power consumption, be difficult for stopping up, the production efficiency height.

Description of drawings

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

The specific embodiment

Referring to Fig. 1, a kind of spoil pulverizer, comprise housing 1, feeding mouth 2, crushing shell 3, sieve plate 4, discharging opening 5, regulate bolt 6, foreign matter collecting chamber 7, rotor 8, tup 9, described feeding mouth 2 is located at housing 1 upper end, discharging opening 5 is located at housing 1 lower end, crushing shell 3, sieve plate 4, foreign matter collecting chamber 7, rotor 8, tup 9 are located at housing 1 inside, regulate bolt 6 and are located at housing 1 side, and tup 9 is located at rotor 8 two ends.

Described feeding mouth 2 is the rectangle of 1000mm * 300mm.

Described rotor 8 diameters are 1000mm.

Before equipment uses, require and to regulate crushing shell 3 and the gap of tup 9 earlier according to product granularity.At first regulate the adjusting bolt 6 of crushing shell 3, maximum adjusted in crushing shell 3 and the gap of tup 9, open drive equipment then, slowly with crushing shell 3 near tup 9 direction adjustment, up to slightly hearing crushing shell 3 and hammer, till the 9 collision sound.Product granularity as required withdraws from crushing shell 3 from the gap adjustment that suitable distance is namely finished crushing shell 3 and tup 9 again.

After material enters feeding mouth 2, be subjected to rotor 8 percussion of the tup 9 of rotation and fragmentation at a high speed, the material that is broken is acquisition kinetic energy outside tup 9 simultaneously, rushes at crushing shell 3 at a high speed.After being subjected to fragmentation for the second time, fall on the sieve plate 4, shearing, extruding, grinding and the material and the interaction between the material that are subjected to tup 9 are further broken, and discharge by discharging opening 5.Can not then enter foreign matter collecting chamber 7 by broken foreign matter, regularly remove.

The spoil mill structure that the utility model provides is simple, the ratio of reduction is big, use cost is cheap, little, the long service life of power consumption, be difficult for stopping up, the production efficiency height.
