Abstract

The invention relates to discharging devices for drum mills-driers and can be used, for example, in cement industry. The aim of the invention is to increase the efficiency of the separation process by reducing the flow rate leaving the discharge port. This is achieved by installing at the end of the discharge port 6 two 4 disks fastened together with bridges, while the disk 3 closest to the discharge pipe 6 is made with a central hole, and the second disk 2 is solid. As a result, the flow of crushed and dried material, the output from the mill, expands and quenches on a continuous disk 2, which ensures effective deposition of particles of material in the lower part of the settling chamber. 2 Il.

The invention relates to equipment for grinding with the simultaneous drying of materials and can be used in the mining, construction and other industries;

The aim of the invention is to increase the efficiency of the separation process by reducing the flow rate of the discharge pipe.

H FIG. 1 shows a drum mill discharge device with a dryer with a partial longitudinal section; in fig. 2 shows a section A-A in FIG.

The discharge device of the drum mill dryer includes a settling chamber 1, a solid disk 2, a disk 3 with a central hole, jumpers 4, a drive shaft 5 attached to the solid disk 2, and a discharge nipple 6 connected to the disk 3 with a hole in the latter. At the same time, in order to increase the rigidity of the structure, jumpers 4 can be set at an angle to the radius of the disks 2 and 3.

The device works as follows.

When the mill drum is rotated by the drive shaft 5, the crushed and dried material is carried by the drying agent through the discharge pipe 6 into the cavity between the disk 3 with the central hole and the continuous disk 2. As a result of the increase in the flow area and due to the impact of the continuous disk 2, the material flow rate decreases and large particles are discharged through the bottom port of the precipitation chamber. The drying agent, which is additionally cleaned from particles of material when interacting with bridges A, is recycled through the upper nozzle of the precipitation chamber 1.
