Problems solved by technology

[0003] The control method of the autogenous mill has a key influence on the working efficiency and reliability of the autogenous mill. The automatic control efficiency of the existing autogenous mill control method is low. When feeding, it is necessary to manually judge whether the feeding speed is appropriate and control Not good, the phenomenon of "swelling belly" is easy to occur. When "swelling belly" occurs, the feeding speed cannot be adjusted automatically and in time; most of the existing self-grinding machines have few safety monitoring devices, the functions are not perfect, and there is no alarm Function and self-protection function

Abstract

The invention discloses a control method for an autogenous mill. A back rotation speed sensor is installed on a transmission shaft. A motor is a variable frequency motor. A motor controller is installed on the motor. A torque measuring instrument is installed on an output shaft of the motor. A weight measuring device is installed on a first bracket and a second bracket. A temperature sensor is arranged on a sliding bearing body. The rotation speed sensor, the torque measuring instrument, the weight measuring device and the temperature sensor are connected with an MCU. A displayer, an alarm and a memory are connected to the MCU. The provided control method for the superfine autogenous mill can automatically judge whether charging is appropriate or not, automatically adjust the charging speed and avoid the swelling phenomenon, is provided with a monitoring device and has alarming and self-protection functions.

Description

technical field [0001] The invention relates to the field of autogenous mills, in particular to a control method for autogenous mills. 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 control method of the autogenous mill has a key influence on the working efficiency and reliability of the autogenous mill. The automatic control efficiency of the existing autogenous mill control method is low. When feeding, it is necessary to manually judge whether the feeding speed is appropriate and control Not good, the phenomenon of "swelling belly" is easy to occur. When "swelling belly" occurs, th...
