Problems solved by technology

The current vertical crusher is composed of a vertical mandrel and a crushing impeller. The upper end of the mandrel is connected with a pulley, and the pulley is connected with the motor through a belt. However, the upper end of the mandrel is a feed inlet. The constraint strength on the upper end of the mandrel is not high, so the service life of the mandrel is not long
