Rod milling cylinder for rod mill, cylinder cover and installation method of rod milling cylinder

Abstract

The invention discloses a rod milling cylinder for a rod mill, a cylinder cover and an installation method of the rod milling cylinder. The rod milling cylinder comprises a cylinder body (1) and a cylinder cover, wherein a circle of round spigot (2) is formed in the top of the cylinder body, two radial notches are symmetrically formed in the circular spigot in regard to the center, first bosses (3) and second bosses (4) which are continuously distributed along the axial direction of the cylinder body are arranged at the position, below the circular spigot, in the cylinder body, the cylinder cover comprises a circular cover plate (5) which can be conformal adapted to the second bossed and arc cover plates (6) which can be conformal adapted to the two radial notches, the arc cover plate sandthe circular cover plate are concentric, and the arc cover plates are fixedly connected with the circular cover plate through a rigid connecting piece (7) and a spring (8) in sequence. The rod milling cylinder has the beneficial effects that a manual self-locking device is formed by the rigid connecting piece, the spring and the arc-shaped cover plates so that the cylinder cover can be assembledand disassembled conveniently and quickly, the structure is reasonable in design, the sample is not prone to loosen and leak in sample preparation, the sample preparation quality meets the geologicalspecification requirement.

Description

technical field [0001] The invention relates to the field of mining machinery, in particular to a rod mill tube, a tube cover and an installation method of the rod mill. Background technique [0002] In the process of preparing rock and mineral samples, the rod mill is currently widely used in geological laboratories with a large amount of sample preparation because of its safety, reliability and high efficiency. The rod mill is driven by the motor through the reducer and the surrounding large gears, or the low-speed synchronous motor directly through the surrounding large gears to drive the cylinder to rotate. The barrel is equipped with a proper number of steel rods as the grinding medium. When the rod mill is working, the grinding medium is lifted to a certain height under the action of centrifugal force and friction, and is thrown or leaked in the rod mill barrel. It falls and is crushed by the moving grinding medium. The crushing force of the rod mill is mainly based ...

AI Technical Summary

Problems solved by technology

[0004] In actual use, due to design reasons, when there is dust in the bolt threads, it is difficult to tighten the bolts. Operators often need to use hands and feet to fix the sample cylinder, and then use tools to start the bolts, which is time-consuming and laborious.

Furthermore, the wear and tear of the bolts is unavoidable. When the bolts are started, the rod mill drum is often toppled due to the gaps in the bolts, which may easily cause injuries to the hands and feet of the operator and pose a safety hazard.

[0005] In addition, due to factors such as the wear of the rod mill cylinder and the deformation of the cylinder body, after the sample is rod ground, the cover plate is difficult to remove on the one hand, and at the same time, the cover plate is prone to dislocation and loosening, and sample leakage occurs during the fine crushing process of the rod mill. Stop the machine and reseal the rod mill

When the cover plate is misplaced, the operator often shakes and vibrates the rod grinding cylinder, taps the rod grinding cylinder with tools, etc. to loosen the cover plate. The labor intensity of this process increases and takes a long time. minutes, affecting the processing time of batch samples
