Abstract

The invention relates to the separation of bulk materials and can be applied in the agricultural, mining and construction industries. The purpose of the invention is to increase productivity by more fully using the working cell surface. The cylindrical trier includes a cylinder (C) 1 with its inner and outer working surfaces, rests on rollers 3 and is placed in a casing 4. The source material is loaded through feeders 7 and 9. Outside, the working surface C 1 on its lifting side rotation is covered by the loading tray 8. Moreover, in the loading area, the bottom of tray 8 is not located below the horizontal axis C 1, and its upper edge is located above the horizontal axis C 1 at a height H≤2 / 3 of its radius. Inside C 1 there is a chute 5 with a screw 6. The source material is loaded into rotating C 1. Short grains are entrained by working surfaces and discharged into channels 5 and 10, and long grains move along C 1 and unload at the opposite end of the load. 2 Il.

This invention relates to the field of bulk material separation and can be used in the agricultural, mining and construction industries.

The purpose of the invention is to increase productivity by more fully using the outer working cell surface.

FIG. 1 shows a cylindrical Trier, a general view; in fig. 2 - ceista surface.

Trier contains cylinder 1 with chemi 2 on the inner and outer surfaces. The cylinder 1 rests on the rollers 3 and is placed in the casing 4. Inside the cylinder there is a chute 5 with a pinch 6 for collecting and removing fines. On top of the cylinder 1 there is a feeder 7 and a feed tray 8 for supplying power to the outer cellular surface. By the feeder 9, the starting material is introduced into the inside of the cylinder 1 to load the inner cellular surface. The removal of grains of the short fraction from the outside of the cellular surface A is carried out along chute 10. Tray 8 covers the outside of cylinder 1 from the side of its lifting during rotation, with the bottom of tray 8 not located below the horizontal axis O | O2 of cylinder 1 in the loading area tray 8 is at a height of / 3 R the radius of the cylinder from its horizontal axis.

Trier works as follows.

The source material is fed separately through the feeder 9 to the inside of the rotating cylinder 1 and through the feeder 7 to the feeding tray 8. When the cylinder is rotated

In the rollers 3 on the wheels 1, the grains of the short fraction fall from the inner and outer sides of the cylinder 1, which are then withdrawn from the groove 5 by means of a choke 5 and through the collecting device 10. The grains of the long fraction are moved in the axial direction of the cylinder 1 and out of casing 4 on the opposite side of the feeders 7 and 9.

The use of the invention makes it possible to increase the productivity of Trier due to more complete use of the outer cellular surface.
