Description

one

The invention relates to a device for fine grinding of various materials and can be applied in the chemical, construction, rural and other industries.

A disintegrator is known, comprising a housing with a feed-in funnel, a nozzle for discharging crushed material and rotating in opposite directions to the inner and outer rotors, on which the grinding elements 1 are arranged in concentric circles.

Due to the constructive solution, this mill cannot be effectively used for fine grinding of many technical materials.

Closest to the proposed technical entity is a disintegrator containing a cylindrical body, mounted in it opposite each other with the possibility of rotation of the working bodies with grinding elements in the form of fingers, one of the working bodies made in the form of a disk with additional grinding elements of rectangular M11 21.

. The disadvantage of this design is the low efficiency of the grinding process.

The purpose of the invention is to increase the efficiency of the material grinding process.

This goal is achieved by the fact that in a disintegrator containing a cylindrical body, working bodies mounted opposite each other with the possibility of rotation with fingers-shaped grinding elements, one of the working bodies is made in the form of a disk with additional grinding elements of a rectangular shape, another working body made in the form of a cup covering disk, supplied with additional grinding elements of rectangular and trapezoidal shape, mounted respectively on its face and sides second surfaces, the latter of which is perforated, thus Tortsov glass surface may be provided with a rim.

FIG. 1 schematically shows a disintegrator, a common fork; in fig. 2, node I in FIG. 1, in FIG. 3 - in FIG. 1, in FIG. 4 - (jr node in fig. I),

The mill contains a housing 1 mounted on horizontal shafts rotors 2 and 3 with fingers 4 and beaters 5. The rotors are mounted on shafts 6 and 7 located on the same geometrical axis. On the rotor 3 having the shape of a glass, percussion elements 8 and 9 of rectangular and trapezoidal shapes are mounted. On the housing 1, the loading and unloading nozzles 10 and 11 are located. The rotors are driven into rotation by means of driving pulleys 12 and 13. The face surface of the rotor 3 is perforated with holes of a hole type 14 and has a rim 15.

Disintegrator works as follows.

The source material of the boot nozzle 10,. Enters the center of the rotor disintegrator. Passing successively all the rows of fingers 4, the material particles are subjected to grinding by the blades 5 of the fast-rotating rotor 3 and the impactor elements 9 of the rotor 2. The material moving in the annular gap is additionally crushed when the lateral impact elements 8 are hit. field of rotation through the holes 14 of the rotor 3. The side rim 15 eliminates the possibility of relatively large particles escaping from the grinding zone. The height of this rim, depending on the geometrical dimensions of the machine, can vary in limits of 10-20 mm. The finished product exits through the discharge pipe 11.

In the specified device provides an increase in the average time

the presence of particles of comminuted material in the grinding zone and, thus, increase the efficiency of the device. The perforated surface of the rotor facilitates the rapid unloading of fine material from the grinding chamber.

Claims (2)

1. A disintegrator comprising a cylindrical body mounted in it opposite to each other with the possibility of rotation of working bodies with grinding elements in the form of fingers, one of the working bodies made in the form of a disk with additional grinding elements of a rectangular shape, characterized in that the effectiveness of the grinding process, another working body is made in the form of a cup-covering glass, equipped with additional grinding elements of rectangular and trapezoidal forms, mounted ootvetstvenno at its end face and side surfaces, the latter of which is perforated. 2.
