Abstract

The invention relates to the field of comminution and makes it possible to increase the efficiency of comminuted by increasing the contact area in which the particles of material (M) rotate at maximum peripheral speeds that are the same across the entire side surface. The grinding chamber (CI) is made of a concentric ring 45 (L INO CO with 05 Figure 1

The invention relates to devices for grinding various materials and can be used in the metallurgical, mining, coal and other industrial sectors.

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

On ($ 1. 1 shows the device, the general view; in Fig. 2 - section A-A in Fig. 1.

The device for grinding materials consists of a stanisle 1, a grinding chamber 2, which is made up of annular sections 3,4 and 5, arranged one in another in a horizontal plane with gaps 6 to each other in the tops and bottoms, and a hopper 7, which is fixed on shaft 8. Kohlzensh sections 3,4 and 5 are equipped with grippers 9, rigidly connecting their tips and tips. The inner annular section 3 is rigidly fixed at the apex on the hollow shaft 8, which is full with the possibility of rotational movement in the frame 1 and provided with a driving pulley 10, and the base is mounted on the fixed axis 11 with the possibility of rotational movement. The middle section 4 is fixed on the cylinder 12, which is made with the possibility of rotational movement of the axis 11 and is equipped with a driving pulley 13.

The outer annular section 5 is provided with floating elements 14, made with the possibility of reciprocating movement along the radius of rotation and fixed to the curvature, and the centrifugal force delivers M continuously in the cavity KS 3,4,5, the layers are rotated towards each other. The floating elements 14, hitting the bevels 16 additionally press the layers M, as a result of which intensive grinding M occurs, caused by the collision of particles M along the boundaries of the contact of the layers. The ground M is removed through gaps 6 between CS 3,4,5. 2 Il.

lindre 15, which is attached to the hollow shaft 8. The bed 1 is provided with bevels 16.

The device works as follows.

Through the drive pulley 10, the hollow shaft 8 of the inner 3 and outer 5 annular sections communicate rotational motion with a frequency of rotation o). From the drive pulley 13 to the cylinder 12, together with the middle annular section 4, a rotational movement is reported with a rotational speed a3, j ,. With respect to the middle annular section 4, the direction of rotation of the inner 3 and outer 5 sections is opposite.

In the hopper 7 load material. From the hopper 7 through the cavity of the shaft into the material enters the multisection grinding chamber 2, fill it,

In the grinding chamber 2, the material is caught by the grips 9, begins to rotate and stratify into oppositely rotating annular layers. A pillar of material in the hopper 7 creates a load directed along the axis of rotation, continuously feeding the material into grinding chamber 2, and the centrifugal force delivers the material continuously j cavity of the annular sections 3,4 and 5, pressing the rotating layers against each other.

Flying on the bevels 16, the floating elements 14 additionally periodically compress the layer of material with a certain frequency.

Intensive contact occurs on the contact side surfaces of the layers.

the grinding of the material in the grinding chamber 2, caused by the collision of particles of material on the boundaries of the contact of the layers.

The crushed material is removed through the gaps 6 by anti-rotating annular sections 3, 4 and 5, for which the cylinder 12, the pulley 13 and the base of the bed 1 have openings.

If necessary, a variant of several rotating middle ring sections is possible.

The invention is designed with the ability to rotate. It allows to increase the radial movement relative to the comminution efficiency due to increased and is equipped with a gland of the contact area of the layers rotated in opposite directions with

maximum speeds and additional periodic compression of the layers, 20 wheezes,
