Description

 The invention relates to equipment for grinding solid materials and can be used in food, construction, chemical and other industries, agriculture.

A device for grinding, containing a housing, a vertically located inside of it a rotating conical grinding chamber with a cantilever shaft, a dome with an opening at the top [1]
The disadvantage of the device is low grinding efficiency, severe wear of the working surfaces, the complexity of the design, metal consumption.

A device is known that contains a housing with a loading hole and an unloading nozzle, a vertically placed rotating grinding chamber with a cantilever hollow shaft with blades communicating with each other, a dome with holes for crushed material, grinding bodies [2]
The disadvantage of the device is the design complexity and unreliability in operation, metal consumption, low productivity.

 The purpose of the invention is to simplify the design, increase reliability and performance, reduce metal consumption.

 To this end, in a device containing a housing with loading and unloading nozzles, a moving grinding chamber with an opening for removing crushed material, an air supply system, grinding media, the grinding chamber is made in the form of a sleeve, one end of which is fixed to the housing, and the other or connected to a tape wound on a drive reversing drum, or directly wound on the same drum, the air supply system is installed in the upper part of the housing, and in the sleeve along its circumference there are a number of holes for removing grinding nnogo material.

 In FIG. 1 shows the proposed device in operation; figure 2 device when unloading the grinding chamber.

 The device comprises a housing 1 with loading 2 and unloading 3 pipes, a grinding chamber sleeve 4, one end 5 of which is mounted on the housing, the other end 6 is wound on a drive reversing drum 7 (Fig. 1), or the second end 6 of the sleeve with slings 8 is connected to the tape 9, wound on a drum 7 (FIG. 2) located in the housing, holes 10 for removing crushed material, made in the sleeve along its circumference in a section corresponding to the midsection when lifting the sleeve 4, an air supply system 11 installed in the upper part of the housing, grinding bodies 12, on example balls (figure 1).

 The device operates as follows.

 Through the pipe 2 serves a portion of the crushed material, such as clay, limestone, etc. The system 11 serves air and rotates the drum 7. The sleeve 4 is moved by air and under heavy weight down together with the crushed material and balls 12. Moving the sleeve back and forth causes the pieces of material to collide between themselves and the balls. Pieces are destroyed, frayed and reach the desired degree of grinding. The sleeve can be of considerable size, which allows to increase the volume of the crushed material. When the sleeve moves, all particles of material constantly move inside the grinding chamber and experience a destructive effect. The grinding speed is significant. Depending on the material, the interaction of its particles, i.e. balls are optional.

 The crushed material when the holes 10 enter the mid-section is blown by air into the lower part of the housing 1 and is removed through the pipe 3.

 With a greater degree of grinding, holes 10 are used, with a larger particle size, it is discharged through a sleeve that is lowered and open below (Fig. 2).

 The proposed device is simple in design / non-metal / does not have collapsing elements. In addition, the device provides greater productivity due to the grinding speed and volume of the material being ground.
