Autogenous mill

Abstract

The invention discloses an autogenous mill. A first end cap and a second end cap are separately mounted at the two ends of a drum body. The first end cap is provided with a feed drum, and the second end cap is fixedly connected with one end of a transmission shaft. The feed drum and the transmission shaft are separately mounted on a first bracket and a second bracket. The other end of the transmission shaft is connected with a power output shaft of a reducer, and a power input shaft of the reducer is connected with a motor. The drum body is internally provided with a lining plate and a guiding plate and provided with an annular discharge outlet. The annular discharge outlet is formed in the portion, close to the second end cap, of the drum body and provided with an annular sieve. The technical purpose of the invention is to provide the superfine autogenous mill which is high in efficiency and capable of automatically judging whether feeding is proper or not, automatically adjusting the feeding speed and avoiding the swelling phenomenon, has a monitoring device and is relatively small in occupied space, higher in transmission efficiency and better in reliability.

Description

technical field [0001] The invention relates to the field of autogenous mills, in particular to an autogenous mill. Background technique [0002] Self-grinding machine is also called medialess grinding machine. Its working principle is basically the same as that of ball mill. The difference is that its cylinder diameter is larger. It does not use balls or any other grinding medium, but uses the crushed material itself as the medium in the cylinder. , Continuously impact and grind each other in the cylinder to achieve the purpose of grinding. [0003] The autogenous mill can process any kind of ore, especially when crushing asbestos, iron ore, copper ore, limestone, gold ore, manganese ore and other materials, the effect is better. The most important feature of the self-grinding machine is the large crushing ratio. The ore feed is generally 300-400mm (in special cases, it can be as large as 910mm). [0004] The efficiency of the existing autogenous mill is low. When feeding...

AI Technical Summary

Problems solved by technology

[0004] The efficiency of the existing autogenous mill is low. When feeding, it is necessary to manually judge whether the feeding speed is appropriate. If the control is not good, the phenomenon of "swelling" will easily occur. When "swelling" occurs, it cannot be adjusted automatically and in time. The speed of feeding; most of the existing autogenous mills have few safety monitoring devices, and the functions are not perfect; most of the existing autogenous mills are driven by the drum, which occupies a large space, and the large gear on the drum is easy to enter the dust. Decrease transmission efficiency and reliability
