Problems solved by technology

In order to simulate the working conditions of various ball mills, it is necessary to build multiple falling ball testing machines with different heights such as 8m and 12m. The higher the falling ball testing machine, the higher the cost, the higher the risk factor, and the more difficult the maintenance

Abstract

A variable-speed horizontal grinding ball collision tester is provided. The variable-speed horizontal grinding ball collision tester is characterized in that the variable-speed horizontal grinding ball collision tester comprises a lifting device (5), a horizontal acceleration device (2), a collision wall (1) and an inclined fairway (8); the lifting device (5), the horizontal acceleration device (2), the collision wall (1) and the inclined fairway (8) forms a grinding ball collision circulation channel; the horizontal acceleration device (2) is a speed-adjustable acceleration device. Compared with the prior art, the variable-speed horizontal grinding ball collision tester has the advantages that with a horizontal type adopted, surface plane construction is low in cost, safe in operation, and convenient in overhaul; with a deceleration (variable-speed) motor used, testing grinding balls can get different horizontal speeds, and drop impact effects in mills of different diameters can be simulated by the changing of the speed of the motor or the size of a pulley.

Description

technical field [0001] The invention relates to a collision testing machine, in particular to a collision testing machine for steel ball products. Background technique [0002] At present, in the grinding ball production industry, in order to test the fatigue life of wear-resistant balls (mainly through the number of impact fatigue failures to directly reflect the impact fatigue life of wear-resistant balls), it is necessary to repeatedly increase the wear-resistant balls to A certain height and make it fall, by recording the number of peeling off of the failed wear-resistant ball, the area of ​​the peeling off, the number of broken times, and the resulting broken defects. In order to simulate the working conditions of various ball mills, it is necessary to build multiple falling ball testing machines with different heights such as 8m and 12m. The higher the falling ball testing machine, the higher the cost, the higher the risk factor, and the more difficult it is to overhau...
