Description

The invention relates to crushers for grain and mineral material, namely, cone inertial crushers, mainly for grinding feed, and

The purpose of the invention is to increase the performance and quality of the finished product by adjusting the pressure on the material.

The drawing shows a cone crusher, longitudinal section.

The crusher contains a housing 2 mounted on shock absorbers 1 with a receiving funnel, an outer cone 3 and a hinge support 4 of a centrally located shaft 5. At the upper end of this shaft there are rigidly fixed rotor 6 with a cylindrical lateral surface provided with accelerating blades 7 coupled to the rotor by axes 8. Inside the rotor there is a mechanism for adjusting the angle of inclination of the accelerating blades 7, which consists of a screw 9 connected by a threaded connection with a disk 10 that interacts with forks 11 pivotally connected with the accelerating blades s 7 for moving vilok- 11 when rotating accelerating blades 7 of the rotor 6 are the grooves 12.

On the centrally located shaft 5, by means of bearings 13, there is a movable cone 14 with a shank, on which an unbalance vibrator 15 is fixed, associated with a V-belt transmission 16 with an electric motor 17.

The hinge bearing 4, which is the center of the precession of the shaft 5., has a pin 18 connected through a petal clutch 19 and a V-belt transmission 20 with a drive 21.

The crusher body 2 is provided with a receiving hopper 22.,

Crusher works as follows.

Getting the rotation from the electric motor 17, the unbalance vibrator 15 creates a centrifugal force causing the movable cone 14c with the shank to make a gyratory movement relative to the center of the hinge support 4. Since the movable cone with the shank and unbalance vibrator is mounted on a centrally located shaft 5 with bearings, the shaft rotates at the operation of the rotor 6 does not affect the rotation of the unbalance vibrator and the nature of the movement of the moving cone. The source material, entering from above into the crusher, enters the space between the rotating rotor 6, having a cylindrical surface, and the walls of the receiving funnel 22. The paddle blades 7

rotors mounted at an angle to the direction of rotation exert a force on the material, one of the components of which is directed to the loading slot of the working chamber, i.e. a pressure screw is formed, which contributes to an increase in pressure in the source material and increases the filling ratio of the working chamber. The material thickens, its average speed in the receiving funnel increases, i.e. the weight consumption of the material passing through the crusher per unit of time increases. As a result, crusher productivity is improved.

By entering the space between the outer cone 3 and the movable cone 14, the material is crushed.

To change the angle of inclination of the accelerating vanes 7 of the rotor 6, it is necessary to turn the screw 9, as a result, the disk 10 will move relative to the rotor axis to a new position. Since the forks 11 enclose the disk 10, the movement of the disk causes the acceleration blades to rotate about their axes 8, and during adjustment the forks 11 rotate relative to the accelerating blades and slide along the contact surface with the disk 10.

Since the paddle blades are set at an angle to the direction of rotation, in addition to the axial component, they affect the material being crushed and tangential loads causing mixing of the feed components and their uniform distribution throughout the volume when moving along the receiving funnel, which improves the quality of the feed produced.

The ability to vary the angle of inclination of the acceleration blades allows you to set the amount of pressure of the processed material depending on its type and mode of operation of the crusher.

Thus, using the invention allows to increase the productivity of the crusher and the quality of the finished product by controlling the pressure on the material.
