The invention relates to a device for grinding materials and can be applied in the construction, agricultural and other industries.

A crusher is known, containing i opnyc with a loading and unloading mouths, inside of which place a rotor with fixed pieces of rubber that interact with it on the removable ring of the housing I.

In the known rotor shaft, the rotational motion of the working bodies of the rotor in the plane perpendicular to the movement of the material creates additional resistance at the inlet and leads to unstable transport of the material of high humidity between the pins with the possibility of formation of debris in the shaft.

The most suitable for the present invention is a hammer, containing a crushing chamber with a grinding chamber and a discharge chamber equipped with mouths, with a rotor located in it and a deck with conductor {{m} elements {2.

In this crusher, the directing of the cutter with a spatula was raised. the working bodies of the rotor coincide with the omission of the loaded material. The lack of aerodynamic fabric in the high-pressure torping of the flow of materials with increased wetting leads to sticking of them to the unloading neck and an increase in the coordination in the direction of the material in the discharge neck. This leads to a drop in the osorost of the crushed material, the formation of blockages in the discharge of the throat, a decrease in the productivity and reliability of the material, and a lower volume of the grain. In addition, for transporting the mass outside the dofobshka pavement, additional overload conveyors are required, which is associated with additional metal consumption.

The purpose of the invention is to increase the throughput grinding of materials of high humidity and viscosity by creating a better flow through aerodynamic flow.

This goal is achieved by the fact that in a hammer shlyubilka containing a splitter chamber equipped with a loading and unloading mouths with a deck with anti-shock elements located in it with a rotor, fans are mounted on both sides of the rotor shaft, separated by ne partitions from the cores and on the rotor shaft and forming ventilation chambers, and the discharge opening is designed as a truncated pyramid, the larger base of which is connected to the side walls of the ventilation chambers

FIG. 1 shows a front view crusher; in fig. 2 - the same, side view; in fig. 3 - the same, top view.

Hammer crusher consists of cylindrical housing body 1 with loading 2 and unloading 3 mouths. The discharge port 3 is made in the form of a truncated pyramid with gently tapering inclined walls 4 with an angle of convergence not exceeding 17-45, and the ratio of the exit and entrance areas f (degree of neck constriction) is not less than 0.4. Moreover, the outlet 5 is taken in such a size as to equalize the dynamic pressure created by the droshkoy in the discharge outlet chamber with the full resistance (pressure) of the transport pipeline 6. Inside the crusher body 1 there is a rotor 7 with hammers or no 8 and deck 9 with anti-shock elements . The grinding rotor 7 is provided with coaxially arranged side fans 10 and 11, installed in the verticalization chambers 12 and 13, separated by partitions 14.

The operation of the hammer mill is carried out as follows.

The material entering through the loading neck into the crusher body of the crusher is crushed by thrusts or knives 8 of the rotor 7 and shock-proof elements of deck 9, and under the influence of centrifugal and aerodynamic forces is thrown into the discharge chamber of the rotor 3. As the rotor 7 grows and the side fans W and 11 in the discharge port -3 creates a directed air flow, which contributes to the displacement with the crushed material and the pneumatic conveying of the resulting mixture outside the crusher into the transport pipeline 6. This air flow is enhanced by side fans 10 and 11, which allows increasing the material transportation speed in the direction of gently tapering inclined walls of the discharge outlet chamber with an angle of convergence not exceeding 17-45 ° and the degree of neck narrowing (ratio of output and input areas) not less than 0.4.

The predominance of the dynamic pressure in the chamber of the upper mouth is accompanied by the material being sucked through the feed mouth, eliminates sticking of wet materials on the walls of the upper mouth, ensures the throughput of the device, and its dynamic quality and reliability.
