Abstract

This invention relates to a technique for the separation of bulk materials by strength, and may be. used in industrial materials and other materials. The purpose of the invention is to improve the quality of the separation process due to the additional destruction of conglomerates and intergrowths. Inside the truncated conical reflector, a disk (d) with baffle plates (p) 5 is installed on the drive shaft with gaps between them and at an acute angle to the radius D with the offset of their peripheral edges in the direction of the working rotation D. Parallel to the radius D with the offset relative to it in the direction of the working movement D, guides P 6 are installed. On the periphery of D there are spreading P 7 with their planes overlapping with radial planes D. Under D there is a split hollow truncation cone, under the reflector - riemniki separation products. When the material moves to the periphery D, the material falls on P 5. Conglomerates are destroyed, and strong grains are separated from splices. While P 6 give the flow of material directional movement from one P 5 to another. The preliminarily cleaned material gets on П 7 and is evenly ejected with D onto the surface of the reflector 1 Cp.

The invention relates to the technique of separating bulk materials in terms of strength and can be used by the building materials industry in other sectors of the people.

The purpose of the invention is to improve the quality of the separation process due to the additional destruction of conglomerates and intergrowths.

Fig, 1 shows a separator, a general view; in figure 2 and the section aa in figure 1.

Centrifugal separator contains

the drive shaft 1, on which the spreading disk 2, consisting of the upper ring 3, the lower disk 4 with the fender plates 5, is positioned 20 with gaps one behind the other at an acute angle to the radius of the disk with the displacement of their peripheral edges disc 2, guide plates 6, mounted parallel to the radial planes also with an offset in the direction of rotation, and spreading plates 7, mounted on the periphery of the disc with the alignment of their planes with radial planes. The spreading disc 2 is located in the inner cavity of the truncated conical reflector of the housing 8, under which the educational advancement of the material from one breaker plate to the other is installed. The pre-cleaned material n falls onto the spreading plates 7 and is evenly ejected from the disk onto the surface of the truncated conical reflector 8, where the separation of the grains by strength occurs. The impact of the scattering disc from the spreading disc against the reflector 8. Strong differences, whose elastic properties are higher, bounce further than weak and fall into a split hollow truncated cone 9, weak differences are collected in the chute 13, thereby dividing the material into two classes. strength.

The use of baffle plates in cross section with guides and spreading plates allows one to separate the weak differences from the sturdy grains and conglomerates that are strong in which there are sticking weak differences and cracks. This allows a higher quality of the separation products and a more efficient process. As a result, the loss of durable material is reduced.

The use of the proposed centrifugal separator will allow you to get a more uniform material in strength with a lower content of weak

Xy installed inlet 10 and Krishka 11, at the bottom are the output 12 and 13.

The separator works as follows.

The raw material through the inlet 10 is fed to the spreading disc 2, in which the pieces of material are accelerated. As ds progresses to the periphery of the disk 2, the material gets onto the fender plates 5, where the conglomerates are destroyed and strong grains are separated from the splash sprouting particles as a result of repeated collisions of the material being separated with the fender plates surface, and also partially with the surface of the guide plates 6 give the flow of material a directional movement and do not allow individual pieces to fly off on the sign: the spacing distance after the impact of the fender plates 5. Thus, the subsequent 50
