Pushing motor type swelling detecting device for compound tube mill and pre-swelling control method

Abstract

The invention discloses a pushing motor type swelling detecting device for compound tube mill and a pre-swelling control method, and relates to the technical field of tube mill detecting devices. The pushing motor type swelling detecting device is characterized in that the upper part of a detecting hole (12) is sealed by a tube mill top cover (2), wherein a detecting device is mounted in the detecting hole (12); the detecting device comprises a hollow barrel body (5); the bottom end of the inner part of the hollow barrel body (5) is provided with a detecting head (4) which is in contact with the inner part of the tube mill; and a pushing motor induction assembly is arranged above the detecting head (4); and the detecting head (4) can extrude the pushing motor induction assembly. By utilizing the device and the pre-swelling control method, the swelling state of the tube mill can be detected, and the work of the tube mill can be regulated in real time, so that the tube mill works in the pre-swelling state at the swelling early stage.

Description

Technical field [0001] The thrust motor -type multi -warehouse -pipe abrasion abdomen detection device and pre -expansion belly control method involves the tube mill detection device and technology field. Background technique [0002] Pipe grinding machine is a very important fine milling equipment in modern industries. It is widely used in the production field of building materials, metallurgy, minerals, power and chemical industry.Large -scale grinders generally have multiple warehouse rooms, and their production capacity is very high. When the barriers are used to divide the grinders into two, three or four warehouse rooms of different lengths, it is called a multi -warehouse tube grinding machine.Different places where the multi-warehouse mill and short tube grinding machine are only 2-7 times larger than the diameter. The materials have experienced in the tube grinding machine for a long time, the product is uniform, and the crushing is relatively large.In the multi -warehou...

Problems solved by technology

The bulge of the tube mill is very harmful. The bulge not only causes the tube mill to lose (or reduce) the grinding effect on the ore, but also destroys the stable work of the grinding, and the treatment of the bulge will also cause the concentration of the ore to follow-up operations. and fineness fluctuations affect the normal operation of follow-up operations; in addition, severe belly swelling will cause tube mills, mine feeders, sand return boxes, bearings, gears, etc. to be damaged by impact loads

After the belly of the tube mill is expanded, it is generally treated by stopping the supply of mineral materials and increasing the supply of mineral water. When the phenomenon of belly swelling is serious, more complicated methods such as high-pressure water and manual unloading of the mill are used.

Belly swelling seriously affects the production efficiency of the tube mill
