Technical Field

The invention relates to the technical field of crusher equipment, in particular to an eccentric rotary type cone crusher.

Background

The eccentric cone crusher is widely applied to crushing various ores and rocks with medium or more hardness such as granite, limestone, gypsum and the like in the industries such as mines, buildings, road building and the like.

Eccentric cone crushers are classified into coarse crushing cone crushers (conventionally called gyratory crushers) and medium and fine crushing cone crushers (generally called medium and fine crushing cone crushers). Traditional cone crusher main structure: the transmission shaft, the bevel gear, the eccentric shaft sleeve, the main shaft, the movable cone, the spherical bearing seat, the fixed cone and the like; gyratory crusher main structure: the transmission shaft, the bevel gear, the eccentric shaft sleeve, the main shaft, the movable cone, the suspension bearing, the fixed cone and the like.

The working principle of the eccentric cone crusher is as follows: the eccentric shaft sleeve is driven to rotate by the transmission device, the movable cone body rotates and swings under the urging of the eccentric shaft sleeve, and materials are crushed by the extrusion and impact action of the movable cone body and the fixed cone body. In the working process, the moving cone performs spatial rotation motion, the rotation motion is composed of two kinds of rotation motion, namely, the axis of the moving cone performs conical surface motion around the center line of the machine along with the eccentric shaft sleeve, and in addition, the moving cone performs rotation motion around the axis of the moving cone.

Because the rotating motion of the movable cone around the axis of the movable cone is passive rotating motion and does not generate tangential force, and the rotating motion is greatly influenced by the friction force between the movable cone and the material layer, the movable cone is easy to slide or roll along the material layer in the crushing cavity alternately, and the lining plate on the movable cone is further led to be abraded unevenly.

Based on traditional eccentric formula cone crusher structure reason, the movable cone can not produce tangential force, and eccentric formula cone crusher can block up broken chamber at the course of the work, especially easily causes to block up to shut down to having certain humidity ore deposit rock, heterogeneous ore deposit rock etc..
