Abstract

The invention relates to the field of grinding, namely centrifugal mills for medium grinding of root crops with solid impurities, and can be used in agriculture, light industry and in other areas where processing of root crops is required. The aim of the invention is to improve the quality of the product by separating solid inclusions. The centrifugal mill contains a cylindrical body 1, a rotor mounted therein in the form of a disk 7 with accelerating blades 8, an inclined breaker plate 2, a loading 10 and unloading 5, 6 nozzles. A separator 9 is mounted on the rotor disk, which is a plate in the form of a rectangular trapezium, the acute angle of which is directed toward the rotor axis and is 40-60 °. In addition, the lower part of the body is made in the form of two coaxial helicoids 4 whose direction of turns is opposite to each other. Helicoids 4 end with discharge pipes 5, 6, with the outer wall of the inner helicoid directed perpendicularly to the fender plate 2, which is humered above the rotor. 2 Il. & (L

The invention relates to grinding, in particular to centrifugal mills for medium grinding of root crops with solid impurities, and can be used in agriculture, light industry and in other areas where processing of root crops with solid inclusions is required.

The purpose of the invention is to improve the quality of the finished product by separating solid inclusions.

FIG. 1 shows a centrifugal mill; in fig. 2 - a rotor with acceleration - Imy blades and a separator. I The centrifugal mill consists of a cylindrical housing 1, on the inner surface of which an inclined slab plate 2 is installed, the surface of which is higher than the rotor of the mill is rubberized 3. The lower part of the mill body is made in the form of two coaxial straight helicoids 4 whose coils have opposite direction. Both helicoids end with discharge nozzles for finished product 5 and for solid inclusions 6. Inside the case there is a rotor consisting of disk 7 and accelerating vanes 8. Separators 9 are installed at the end of the disk near accelerating vanes ten.

Centrifugal mill works as follows.

The source material with solid inclusions (impurities) through the loading nozzle 10 is fed to the rotor rotating at a certain speed. The material being crushed together with solid inclusions is accelerated along the rotor and collides with the separator 9. At the same time, the material being crushed due to the fact that it has a smaller

strength than solid inclusions, is cut through by the separator and is thrown onto the baffle plate 2. When a crushed material collides with a baffle plate, its destruction occurs.

The grinding products on the reflective plate 2 and the discharge pipe 5 are discharged from the mill. At the same time, solid inclusions when colliding with a separator deviate from the axial trajectory upward, collide with the gummed section of the fender plate, are reflected from it, enter the collection of solid inclusions (internal helicoid) and through the nozzle 6 are removed from the mill.

Claims (1)

Invention Formula Centrifugal mill mainly for root crops, containing a cylindrical body, a rotor in the form of a disk with blades, surrounded by a sloping baffle plate, loading and unloading pipes, characterized in that, in order to improve the quality of the finished product due to the separation of solid inclusions, it is equipped with an additional discharge pipe and mounted on a disk by separators in the form of plates having the shape of a rectangular trapezium The acute angle of which lies in the range of 40-60 ° and is directed to the rotor axis, the lower part The mill casing is made in the form of two coaxial straight helicoids, the direction of the turns of which is opposite to each other and connected to the discharge pipes, while the outer wall of the internal helicoid is located perpendicular to the baffle plate, the surface of which is located above the rotor is gummed.
