Self-sensing and self-feedback device for crushing solid minerals

Abstract

The invention discloses a self-sensing and self-feedback device for crushing solid minerals. In the device, a raw material self-sensing device faces the interior of a stock bin containing the solid minerals to be crushed so as to detect raw material information of the solid minerals, a crushing motor self-sensing device is arranged on a crushing motor so as to detect operation information of the crushing motor, a material accumulation self-sensing device is located at the lower end of the crushing discharging port so as to detect accumulation information of materials discharged out of the crushing discharging port, and a feeding self-sensing device detects the weight variation in a crushing cavity within unit time; and a crushing motor feedback device is connected with the crushing motor to control operation parameters of the motor, a conveying feedback device is connected to a conveying device arranged below the crushing discharging port to control the conveying speed of the conveying device, a control device sends an instruction to the crushing motor feedback device to adjust the operation parameters. and the masses of the materials entering the crushing cavity are controlled to be the same in unit time. According to the device, and the crushing efficiency of the materials passing through the crusher once is improved.

Description

technical field [0001] The invention relates to the technical field of crushing solid minerals, in particular to a self-sensing and self-feedback device for crushing solid minerals. Background technique [0002] Solid minerals usually need to be crushed in the process of production and use, especially in the field of mineral inspection, it is often necessary to crush large solid minerals to a certain particle size through a crushing device for subsequent use or analysis. Common crushing devices include roller crushers, jaw crushers, hammer crushers, vertical crushers, horizontal crushers, etc. The rotating parts of these crushing devices usually adopt fixed speed and work with constant power. When encountering extremely hard materials, the particles of the crushed materials will increase and cannot meet the requirements of use. It is often necessary to crush large particles again until all the particles meet the requirements of use. When encountering wet and sticky materia...

AI Technical Summary

Problems solved by technology

When encountering wet and sticky materials, the inside of the crusher often has the phenomenon of material sticking and clogging. With the accumulation of materials, the crusher will eventually stop and the crushing process cannot be carried out. In severe cases, the drive belt of the crushing motor will be damaged, or even damaged. Crusher motor

At this time, the sticky material in the crusher must be cleaned by manual cleaning, and the crushing operation is performed again, which greatly reduces the crushing efficiency.

The crusher usually crushes the material at a constant speed. When the amount of material is small, the phenomenon of excess output power will occur, resulting in energy waste
