Analyze the shape and process characteristics of the crusher cavity

The shape of the crushing chamber is linear or curved. When the moving pendulum swings to the dotted line position, it falls to the horizontal plane. The vertical distance between the two horizontal planes is the distance that the stone blocker falls when the rock breaking machine is in the idle stroke. In the next working stroke of the seesaw, the horizontal plane The material block is broken, and when it is idle, the material falls to the horizontal surface, and so on, the material block is gradually broken and the particle size is gradually reduced, and finally discharged through the discharge port.

In the linear crushing chamber, the volume of the trapezoidal section formed between successive water levels decreases downward in turn. The gap between the materials is gradually reduced, and the swinging stroke and crushing force of the moving jaw are gradually increased, and the discharge speed of the material near the discharge port is slowed down, so that the gambling game is likely to occur near the discharge port. Phenomenon, this is the main cause of machine overload and serious wear on the lower end of the liner.

The curved crushing chamber is designed to change the fixed lining plate into a curved shape, and the curve is designed according to the principle that the corner of the crushing chamber gradually decreases from top to bottom. In the curved crushing chamber, each associated horizontal plane is formed. The volume of the trapezoidal section gradually increases from the middle of the crushing chamber, so the gap between the materials is increased, which is conducive to the discharge. Since the gambling point is moved up, the gambling phenomenon is not easy to occur in the vicinity of the discharge port. The structural design of the crushing chamber of the crusher is designed according to its actual needs, and different design methods are used to achieve different crushing methods.
