Abstract
Disclosed is an impact-type crusher, mainly comprising a pendulum-type crushing mechanism for coarse crushing and a pin-disc-type crushing mechanism for fine crushing. A fixed eye filtering net is arranged between the two crushing mechanism sections. With the pressure difference formed by the comparatively large speed difference between the two crushing mechanism sections, materials can automatically pass the fixed eye filtering net and enter the second crushing mechanism after being crushed in the first crushing mechanism, so the next step of crushing work can be achieved without specific unloading devices or manual operation; also the crushing particle size can be adjusted according to requirement. The utility model has simple structure and is convenient for the manufacturing of middle-small machinery. The crusher is suitable for crushing work of solid materials in fields of chemical engineering, medical industry, biological engineering and daily life.
