Description

The baffle houses 13–15 carry out sieves made from a thick sieve with round cone-shaped ores, which provide the desired grinding unit for one grinding module. The sieve matrices are fixed against each accelerator; G1p help thrust bolts 16-18.

On the Varkhn, the base plate was installed: :::; cargo hopper 1 so that the boot windows on its bottom coincide with the boot windows of the plate. A conical funnel / 9 is attached to the upper plate to the upper plate for directing the mirror 1a. The conical funnels 20 are made in the form of c: IU (NCS sieves and at the same time pitched planks, therefore, in the upper part of the funnel) are fixed, and from the bottom one is solid.

For removal of the IZ | Melted grain of the shotgun, the pitched boards 21 and 22 are installed with the shape of a truncated 1 cone with a smaller base upwards. To the lower base plate pr; branch pipes 23 are fastened. Drive shaft with accelerating disks is made of: a high-frequency asynchronous electric motor located through a centrifugal friction clutch, the driven disk 24 is shown in FIG. I.

Works centrifugal multistage crusher as follows.

The grain to be crushed is loaded into the bunker /, from where it feeds on the cone / 9 to the accelerating disk 9. The accelerating disks, made in analogy with the impellers of high-speed centrifugal fans, create suction through the loading windows of the air flow, which contributes to the movement product. Consequently, the discharge ports of the acceleration discs are at the same time the suction nozzles, therefore, the acceleration disc enters not only under the action of gravity, but also under the action of air pressure.

The grains or parts of it on the accelerating disk acquire the dredal velocity and, striking the sieve matrix, are destroyed. The destruction occurs due to the impact of the grain on the blade, the impact of the o-grooved sieve-matrix, cutting of the sharp edges of the sieve-matrix and penetration of 3 holes on the grid. The grain in the first stage is destroyed by an impact on unequal parts.

Those of them that do not exceed a predetermined size are retracted:; from the diets through the sieves and conical sieves, and the rest go to the next disk of large diameter. On this disk, the particles acquire greater speeds, which is necessary for their subsequent destruction, since the impact of cHvia is directly proportional to the mass and velocity of the Particle. In this way, a uniform product is obtained.

granulometric composition with a smaller amount of flour dust.

The application of the indicated centrifugal multistage force allows to achieve the goal - to increase the efficiency of the process pz: ae; xen, and.

Form Y: 1. A centrifugal multi-stage crusher, which is grain-driven, contains a distribution and distribution chamber in which a rotor, fender decks, loading and unloading holes, respectively located in the upper and lower parts of the chamber, are installed on the vertical shaft h and y w and with the fact that, in order to increase the efficiency of the grinding process, the rotor is made in the form of accelerating disks mounted on a vertical shaft, the diameter of which increases as it approaches the discharge opening.

2. Crusher according to claim 1, that is, so that the fender decks are made in the form

sieves of matrices, the bumps of which have the shape of a truncated ko, nus, directed by a large base; -: walls of the receiving-identifying hamera.
