During its precision machining,the transversal rupture occurs on the taper spindle of a vertical crusher applied by a mine after heat treatment.

The article analyses a reason why the original main bearing is easy to be worn by calculating the pulling force at the main shaft side of vertical shaft hammer crusher.

Application of PSFL shaft-axis crusher in grinding process;

The basis on structure characteristics of the upright impingement crusher,analyzed a certain method of the model basic parameter,such as the rotator line speed,rate of production and the electric motor power etc.

Study on rotor load of vertical shaft impact crusher based on ADAMS

Simulation analysis shows that the speed of the rotor is an important factor that impacts the crushing quality and efficiency of the vertical shaft impact crusher,but the crushing effect is not always rising with the speed increasing and high speed would aggravate the wear and tear of main butt ends.
