TECHNICAL DESCRIPTION

General description of the structure:

The crusher's body is made of a sheet of appropriate thickness, which creates a rigid and light box structure. There is a fixed jaw in the body. The movable jaw is placed in the pendulum, which in turn is suspended on the axis. The pendulum axis is mounted in sliding sleeves. The crusher's eccentric shaft is mounted in rolling bearings placed in non-split sleeves and in a separable housing, which is also a connecting rod. The rolling bearings are protected against dust with an appropriate labyrinth seal Bearings are lubricated with grease. In the pendulum and in the connecting rod there are bearing strips between which the expansion shaft is located. Proper cooperation of the expansion shaft with the strips and tightening the pendulum to the connecting rod ensures spring with a tendon. The eccentric shaft with flywheels and bearings is placed in the body openings and fixed in them by means of clamps and tensioning bolts. Flywheels, one of which is grooved, are mounted on the eccentric shaft by means of a key.

A description of the action

The torque from the electric motor is transmitted through the belt-wedge transmission to the eccentric shaft of the crusher, on which the bearing housing, which is also the connecting rod, is mounted on the eccentric part. The rotating eccentric shaft transmits the swinging movement through the expansion shaft to the movable jaw mounted on the pendulum. When the pendulum moves forward, the material fed to the crushing chamber is crushed to the size of the set outlet gap. When the pendulum moves back, the crushed material falls out through the widening gap. The work of crushing in the crusher is therefore cyclical and takes place only during the forward movement of the pendulum. The energy supplied by the engine during idle motion is absorbed by the flywheels through which it is released during operation.
