Abstract

1. ROTOR MILL, containing a cornus, in which a rotor is mounted on a horizontal shaft, bouncing elastic plates installed one below the other, loading and unloading nozzles, so that, in order to reduce the grinding efficiency the casing and rotor of the mount of fowan shell, on the inner surface of which are mounted elastic. : plates, with slots in the shell between the plates. 2. The mill according to claim 1, characterized in that the rotor is made in the form of a disk with saw-tooth projections. 3. Mill pop 2, in that channels are formed between saw-tooth projections, on which guide rails are installed above the rotor side. but

Description

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

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

Fig. 1 shows a rotary mill, longitudinal section; nafig. 2 is a section AA in FIG. 1; in FIG. 3 - channels for air intake.

The rotary mill contains a housing 1 with a loading 2 and unloading 3 nozzles. On the casing 4, installed between the housing 1 and the rotor 5, elastic plates 6 are fixed one below the other, forming an elastic baffle plate. Slots 7 are made between the elastic plates 6 in the casing 4. The mill torus 5 is made in the form of 8 sawtooth protrusions. In the rotor 5, channels 10 for coca air are made between the sawtooth blunts, at the base of which are installed

Mill way.

The initial eye tube 2 falls on the protrusions 9 of the rotor 5 is discarded on uyrugi plate 6,

Rodis. 9.

rails 11, works as follows material through grinding

while due to the impact on the protrusions 9 of the rotor 5 and the elastic plate 6 of the stationary shell 4. This process is repeated until the crushed material, having reached a certain size, is removed. through the slots 7 of the shell 4 in the discharge pipe 3.

The installation of the guide strips 11 in front of the channels 10 in the rotor 5 contributes to an additional intake of air from the outside into the working area of the mill, as a result of which the grinding process of particles is intensified due to self-abrasion in developed vortex flows, and the cooling of the crushed material and impact organs of the mill is improved and transportation of the finished product to the discharge pipe 3.

When grinding easily loose abrasive materials, the working surface of the protrusions of the rotor can be made concave, which protects the quality of the finished product and increases the life of the mill rotor. In this case, the grinding process occurs due to the impact of particles of material on the lining layer deposited on concave surfaces

rotor protrusions
