Miniature gyratory crushing mechanics test bed

Abstract

The invention discloses a miniature gyratory crushing mechanics test bed. The miniature gyratory crushing mechanics test bed comprises a cover plate, a base, an outer slide rail component, an inner slide rail component, a rotating component, a crushing cavity and an angle adjuster. A movable cone lining plate is driven to rotate under the combined action of a pin roller and a spring to periodically extrude ore particles in the crushing cavity, and simultaneously, a sensor starts to collect data such as load spectrum, crushing force and crushing force distribution and transmits the data to a microcomputer in real time, operators can perform control through the microcomputer to adjust the angle adjuster and adjust the inclination angle of a fixed cone lining plate according to the actual crushing situation, also can adjust the inclination angle of the movable cone lining plate by adjusting the position of a shaft sleeve seat, and can adjust the rotating speed of a main shaft, and the movable cone lining plate and the fixed cone lining plate can be replaced, so that ore crushing tests under multiple working conditions such as different meshing angles, different rotating speeds and different cavity type curves are achieved under laboratory conditions, the internal load distribution of the crushing cavity and the torque distribution of the rotating shaft are obtained, and the wear condition of the lining plate of the gyratory crusher is predicted.

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
