Technical Field

The invention relates to the technical field of crushing tools, in particular to an extrusion type crusher with a bionic crushing mechanism.

Background

Attapulgite is a rare mineral resource. The crushing of the mined attapulgite is an essential link for concave-convex utilization. Because the humidity is too big (the moisture content is more than 20% under general condition), the attapulgite belongs to viscidity material or super viscidity material, leads to the granule after smashing to glue or attach to the blade disc easily, seriously influences work efficiency even destroys equipment. Therefore, there is a need to provide a crusher for viscous materials.

For example, chinese patent publication No. CN204583382U discloses an attapulgite clay pulverizer.

After the attapulgite is dried, the bonding structure between the attapulgite and formed by water molecules is broken. The properties of attapulgite as a nanomaterial are therefore easily destroyed. Moreover, drying requires excessive electric energy consumption, and is not in accordance with the environmental protection concept.
