Description

one

The invention relates to the field of grinding materials and can be used in the mining, coal and building materials industries for medium and fine crushing of ore, coal, rubble or gravel.

A centrifugal dust remover is known, comprising a housing with outer and inner walls, a dust collector, and a shaft with a spreading disc and a fan wheel.

The purpose of the proposed device is to combine crushing and dedusting operations in one device, reducing capital and operating costs and reducing energy costs.

This is achieved by the fact that accelerating vanes are mounted on the spreading disc, and crushing plates are installed on the inner wall of the housing, and a grill is mounted between the spreading disc and the fan wheel.

FIG. 1 shows a crusher, a longitudinal section along the axis of rotation of the rotor; in fig. 2 is a section along A-A in FIG. one; in fig. 3 is a section according to BB (along the safety grid) in FIG. one.

The arrows and solid lines indicate the movement of solid material, the arrows and dashed lines indicate the movement of air.

Centrifugal Impact Crusher includes

the case, having 1 inner and 2 outer walls with a zero annular gap 3 between the nanometers; feed hopper 4; hollow vertical shaft 5, which is mounted

rotating in the horizontal plane the rotor 6 with accelerating blades; reflective sheets 7, located around the entire circumference of the inner wall of the housing; fan wheel 8, mounted on shaft 5 above

rotor 6; a grating 9 located between the rotor and the fan wheel and serving to protect the fan wheel from impacts reflected by: heels of the material and directing the ascending air flow;

adjusting 10, which overlap the annular gap in the inner body along its entire circumference and the employees are adjusted from the air flow upstream, and the investigator is 1o, and

separable dust; a dust collector 11 formed by KO1 IChEK MI parts of the outer walls of the housing; opening 12 for discharging crushed mineral; an opening 13 for unloading dust and an electric motor 14, rotating the shaft 5 through the gear 1 and the gear 15.

The described fractional fraction works in the following way. Subject to crushing the material through the boot of the crow 4 and the hollow shaft 5

enters the rotor 6. Pviga along blades

rotor under the action of centrifugal force, pieces of material are accelerated to a certain speed, fly out of the rotor and fraction-ps from hitting the reflective plates 7.

A fan wheel 8 mounted on the crusher shaft above the rotor 6 of the vranda; it together with the shaft creates a closed stream of air (shown in fng. 1 with a dotted line), rising in the crushing zone (between the points;, at the rotor 6 and the reflective lambs 7 ) n pskhod nschy in the ring gap between the walls of the housing.

The passage through the window between the rotor and reflective pipes, the rising air stream picks up the dust when crushed, and carries it through the grid 9 and the valve 8 and brings the wheel 3 between the inside and the outer 2 walls of the corns into the collar. The dust-free crushing product pushes into the inner cone of the housing and is discharged from it through the opening 12. The grating is located between the rotor and the fan and the grille 9, 1 and the fan wheel is worn or broken due to impacts on the reflected pieces of material, and sprang P1, sd air flow in the zone of crushed.

In the annular gap 3 between the walls of the housing, the air flow together with the dust moves downwards. In front of entrance

In the annular gap, which is blocked by the louver 10, an air note sharply changes the direction of movement, the particles ache, heavier than air, and the force of gravity and inertia is extracted from the flow and deposited on the dust collector 11, from where they are unloaded through the opening 13.

 through blinds and ring horn of cornus, freed from dust air

notes becomes the rise of the PCM, passes through the crushing zone again, dust is carried away, etc. Blinds 10 can be reframed by changing the gap between them. This is achieved by adjusting the air flow rate, and hence the size of the dust to be separated.

Subject and d on and e and

Pentebury desalter containing Huni Cornus with outer and inner walls, Dust collector Beater with spreader disk and fan wheel, characterized by the fact that, in order to combine in one device the crushing and desalting operations, reduce capital and operating costs; Accelerating paddles are mounted on the disc, and on the inner wall of the cornus there is a fraction of the plate, and between the scattering disc and the thorium

wheel mounted grille.
