Rotary Crusher Overview

Posted on

The production of the gyratory crusher has been more than 100 years old. Because its production capacity is 3-4 times higher than that of the jaw crusher , it is a typical equipment for crushing various hard materials in large mines and other industrial sectors. Since the 1950s, China has copied and designed some specifications of gyratory crushers, but its production and use effects are not ideal. Until the end of the 1970s, the design level of China's gyratory crushers was close to the international advanced level in the 1970s. In the past 10 years, the production and sales volume of China's gyratory crushers has been relatively low, and the development has been slow. There is still a certain gap with foreign countries.
The gyratory crusher basically has three types: fixed shaft type, inclined surface discharge type and center discharge type. Due to the many shortcomings of the first two forms, at present, only the center discharge type gyratory crusher is produced and used in China.
The specifications of the gyratory crusher are different in different countries. In China, the width of the feed port/width of the discharge port is indicated.
