Description

Izstrbstenio refers to the technique of grinding u- iiiM 1.- | These materials, in particular, for the installation of grain grinding, more specifically for hammer crushers, and for the use in the KombikorMoiiDii industry or in the production of feed (I in ce.ibCKoM host.

Proceedings of the newsletter, etc., consisting of a KopiiNca, hammer rotor, deck, sieve and drive, in which the deck and sieve are spaced Bceii to the length of the hammer rotor, and the deck occupies one quarter of the circumference of the grinding chamber, and the loading opening is / southern in the upper part of the crushing chamber along its entire length 1 |.

However, due to the insufficiently ill rotation of the deck, the S1A1A part of the enters into e) the abundant chamber makes it possible to crush to the required size, does not pass through the sieve and is not removed from the manshna. This leads to rapid wear of the sieve, prevents the effective grinding of the newly added product, limits productivity and reduces the availability of the crusher.

It is also known a device for grain grinding, 1, consisting of a three-sided rotor, a sequence. 11) But dispersed BD1). it has a cylinder, a sieve, a sieve and a cornus with a bottom hole, which is razno. in the upper part of the deck above my. lOTKOBIibl RS) (TO) OM.

The output is fragmented. 1e11pogo product in the device osus1vestel egs c. Only through the sieve surface 2.

A disadvantage of the known device lies in the fact that when crushing a grain characterized by elevated viscosity, a part of it, such as a deck, and a sieve surface, and not being sufficiently ground, accumulates in the end portion of the sieve surface adjacent to the body. This part of the product under the action of the end of the hammers of the rotor lies around the normality of the sigon shell, but it has a mixture of the effective sieving surface. At the same time, unwarranted and unequal () 1e) wear of hammers and wear of the sieve occurs, which reduces the reliability of the device.

The aim of the invention is: iioBiiHiienne crusher reliability in operation.

This goal is achieved by the fact that in the device for measuring:: a worm, consisting of. Hammer yutor, successively located along the cylindrical deck and a sieve with an intake pipe, for outputting the inconsistent product, and a body with a boot. located in the lower part of its end wall, the nozzle is located in the upper end, but the movement of the product of the sieve and beyond the body.

FIG. 1 shows the proposed device for grinding grain, longitudinal

0 cut; in fig. 2 is a section of L.P. pa of FIG. I (discharge nozzles for ground product).

The .g1 grain grinding device contains a Mo.ioTKOBi.ni rotor 1 with disks 2, a hammer. 3 and a drive m, for example, through a tongue

5 4 for the rotary-type rotor 1 around the axis 1 - 1. Along the rotor 1, there are successively one after the other deck 5 and a sieve 6, which have a cylindrical shape and are placed in the cornus 7, having end walls 8 and 9.

0 The housing 7 is provided with a 10 placed around the sieve B and a hopper 11.

At the top end of the product movement, a part of the sieve, near the end wall 9 of the housing 7, has a nozzle 12 having an outlet outside the housing limits.

five

In the lower part of the end wall of the Cornus 7, the loading opening 13 is located for nodalisation of the product in the grinding bowl.

The device works as follows

After the rotation of the hammer rotor 1, through 4 in the hole 13 through the pipe 14 serves grain. In space bounded by a deck of 5 n disks 2 of the rotor 1, the grain is subjected to the impact of hammers 3 of the rotor 1.

Prepend. the crushed minerals, product 3, enters product 6, where sifting occurs and additional product, which is passed through sieve 6. The product passed through sieve 6 enters chamber 10 and the outlet hopper 11, from where B1 goes outside.

A part of the product, not a neckshield, through a sieve (), reaches the end wall 9 of the housing 7, B1 | hammers 3 of the rotor 1 through the output () D | pipe 12 in that pl different direction depending on the direction of rotor rotation.

Throwed out of the body, the insufficiently crushed product is sorted if necessary and dredged by bitwise grinding, for example in the device; similar to the proposed.
