The invention relates to cone inertial crushers and can be most widely used in mill sections of enrichment plants. The aim of the invention is to simplify the design and increase reliability. The crusher includes a housing 1 with an outer cone 2 and an inner cone 3, on the shaft 4 of which, using a bearing, unbalance 5 is placed with the planet carrier in the form of a shell 6 installed in the bearings of the housing 1. The shell 6 is equipped with two internal projections between which there is a projection of unbalance 5. Rings with radial ribs are fixed on the outer surface of the shell, between which grinding wheels are freely placed, the shaft 12 of the shell is equipped with a pulley 13 connected by a text transfer 14 with an electric motor 15. A hollow box is fixed on the body tso 16 connected with the output apertures area of crushed material from the conical comminuting chamber 17. Out of the hollow ring is connected to an exhaust system to remove the particle size of the finished product. 2 silt, tj (L with Os VJ 00 fe 15 Figure 1

Description

The invention relates to cone inertial crushers and can be most widely used in mill sections of enrichment plants.

The purpose of the invention is to simplify the design and increase reliability.

Figure 1 shows the structural scheme of the proposed crusher, a longitudinal section; figure 2 - section aa in figure 1.

The crusher includes a housing 1 with an outer cone 2 and an inner cone 3, on the shaft 4 of which, by means of a bearing, unbalance 5 is placed with the carrier in the form of a shell b installed in the bearings of housing 1. The shell 6 is equipped with two inner projections 7, between which a projection 8 of unbalance is placed 5. On the outer surface of the shell 6 are fixed rings 9 with radial ribs 10, between which the grinding rollers 11 are freely placed. Shaft 12 of shell 6 is provided with a pulley 13 connected by textrop 14 with an electric motor 15. On the case 1 a floor is fixed A ring 16 connected by a hole to the exit zone of the crushed material from the conical crusher chamber 17. The exit from the hollow ring is connected to the exhaust system to remove the finished product.

Crusher works as follows

During the rotation of the shell 6 through the protrusions 7 and 8, the unbalance 5 receives rotation, which gives a gyration movement to the internal cone 3 due to the developed centrifugal force. Between the cones 2 and 3, the material is crushed, which is discharged from the crusher chamber 17 and cleaned of the pulverized class by drawing a ring around the body 1 of the hollow ring 16. Coarser material

falls between the inner surface of the wall of the housing 1 and the rollers 11, which roll around the wall through a layer of material, remaining between the ribs 10, which are their pushers during rotation

shells 6. Thus, the material is reduced to the desired size.

The absence of lever-shaped bearings and hinges typical of the prototype greatly simplifies the crusher and ensures its reliability. The intermediate pneumatic extraction of the finished product through the hollow ring 16 increases the crusher's efficiency by increasing productivity by 20%.
