Description

eleven

The invention relates to the grinding equipment of a single device to dumping devices of drum mills, which can be used in the mining, cement and other industrial sectors.

The purpose of the invention is to increase the productivity of the mill by intensifying the unloading of crushed material S

FIG. 1 shows a drum mill discharge device, a longitudinal section I, FIG. 2 a section AA in FIG. 1; in fig. 3 -elevator 5 isometric.

The unloading device of the drum mill includes a discharge grid 1, a discharge cone

2 and radially arranged elevators 3j provided with a sloping partition 4 dividing the volume of the elevator into a peripheral 5 and an internal b chamber, in the side walls 7 of the elevators

3 between the ends of adjacent partitions

0

The pulp material crushed in the mill drum passes through the openings of the discharge grid 1 and enters the chambers 5 and 6 of elevators 3. When the mill drum rotates, the material from chamber 5 flows through the windows 8 into the chamber 6 of the neighboring elevator “Hitting the inclined partition 4z this material begins to move along it to unload earlier than the second g in the direction of rotation of the drum, the side wall 7 of the elevator 3 crosses the horizontal axis of the mill and along it begins to slip material entering the chamber 6,

By the time of intersection specified

the wall of the horizontal mill base material from the chamber 5 is shifted to this wall and directed with further

5 rotation of the drum for unloading to the cone 2 together with the material of the chamber 6.
