A micro gyratory crushing mechanics test bench

Abstract

The invention discloses a miniature gyratory crushing mechanics test bench, which comprises: a cover plate, a base, an outer slide rail part, an inner slide rail part, a rotating part, a crushing cavity and an angle regulator. Under the joint action of rollers and springs, the movable cone liner periodically squeezes the ore particles in the crushing cavity. At the same time, the sensor starts to collect data such as load spectrum, crushing force and crushing force distribution, and transmits them to the computer in real time. According to the actual crushing situation, the operator can adjust the angle regulator to adjust the inclination angle of the fixed cone liner through the microcomputer control, and can also adjust the inclination angle of the movable cone liner by adjusting the position of the sleeve seat, and can also adjust the spindle speed, the movable cone The liner and the fixed cone liner can be replaced, so as to realize the ore crushing test under different working conditions such as different angles of engagement, different speeds and different cavity shape curves under laboratory conditions, and obtain the load distribution inside the crushing cavity and the rotation shaft. Torque distribution to predict gyratory crusher liner wear.

Description

technical field [0001] The invention relates to a mining crushing machine, in particular to a miniature gyratory crushing mechanics test bench. Background technique [0002] At present, more than 90% of my country's energy, more than 80% of industrial raw materials and more than 70% of agricultural production materials come from mineral resources. In the process of mineral raw material processing and utilization, crushing and grinding account for more than 60% of the power consumption of the entire concentrator. Because the efficiency of the mill is only 1%, the efficiency of the crusher reaches 10%. Therefore, moving forward the power consumption of crushing and grinding to achieve the technical goal of "more crushing and less grinding" in the crushing and grinding process is the key to increase production, increase income, save energy and reduce consumption in mineral processing plants. With the continuous improvement of quality requirements, large-scale gyratory crusher...

Problems solved by technology

It is costly and unrealistic to obtain data such as crushing force, wear degree, stress distribution, material crushing effect and crushing chamber load spectrum directly from the actual working process of the gyratory crusher. Currently, the main ways to obtain these data are It is the static compression experiment, numerical simulation and theoretical derivation. These methods are quite different from the actual working conditions, and there are large errors in the experimental data. Moreover, there are no instruments and tools specially used to measure these data on the market. This will seriously Hinder the design accuracy of design R&D workers
