Grate seam self-cleaning device of ball mill

Abstract

The invention discloses a grate seam self-cleaning device of a ball mill. The grate seam self-cleaning device comprises grate plates, an installation plate, an installation base, a spring and a buffersleeve. The grate plates can be spliced to form a circular bin partition plate, and the grate plates and the installation plate are connected and fastened through bolts. The installation base is connected to the inner wall of a barrel of the ball mill through bolts. The circular bin partition plate and the installation base are connected through the spring. The buffer sleeve is arranged outside the spring in a sleeving manner to prevent collision between the bin partition plate and the installation base. Horn mouths are arranged on grate seams on the grate plates. By means of the horn-shapedgrate seams, coarse particles are prevented from being stuck at the positions of the grate seams. The bin partition plate composed of the grate plates can shake by itself in the operation process of the machine, and therefore materials stacked at the positions of the grate seams are shaken off and shaken to be loose, and self-cleaning of the grate seams is achieved.

Description

technical field [0001] The invention belongs to the technical field of ball mills, in particular to a self-cleaning device for ball mill grate seams. Background technique [0002] The ball mill is the key equipment for crushing the material after it is crushed; the ball mill is composed of a horizontal cylinder, a hollow shaft for feeding and discharging materials, and a grinding head. The hollow shaft at the material end is put into the barrel. When the barrel of the ball mill rotates, the grinding body is attached to the liner of the barrel and taken away by the barrel due to inertia, centrifugal force and friction. When brought to a certain When it is high, it is thrown down due to its own gravity, and the falling grinding body crushes the material in the cylinder like a projectile; [0003] There are usually multiple grinding chambers in the ball mill, and the grinding chambers are separated by partition boards; the ball mill introduces wind into the cylinder through a ...

AI Technical Summary

Problems solved by technology

[0003] There are usually multiple grinding chambers in the ball mill, and the grinding chambers are separated by partition boards; the ball mill introduces wind into the cylinder through the fan to promote the flow of materials, and the materials that are ground to a certain size enter through the sieve or sieve holes on the partition boards. The next grinding chamber is used for grinding. In the actual production process, coarse particles are often stuck on the sieve or sieve holes, causing blockage of the sieve or sieve holes, which affects the normal passage of materials. If the internal temperature is too high, the machine will be damaged, and the blocked sieve gap or sieve hole will take a lot of time and manual cleaning, which will greatly affect the production efficiency.
