Introduction to Performance and Structural Features of Impact Crusher

Impact crusher shell is mainly composed of feed hopper, upper shell and lower shell. The semicircle sieve plate in the lower shell forms discharge port.

The central shaft is equipped with stringed support plates. The support plates are bonded together by supporting rods, which are installed with hammers.

Both the arc-shaped lining boards and the inlet mouth are fixed with impact boards, which are vertical to the tangential direction of the hammer head. Actually, how much we know about the widely applied limestone impact crusher? Now we will have a detailed discussion about the structural features of the impact crusher.

The advantages of this series of impact crushers are high fed-in material granularity and low investment cost. The manganese steel lining plates play a protective role in the machine.

The impact surface is arc-shaped. The obliquely placed inner impact boards and the impact surface are in linear distribution. Each impact board is fixed with longitudinal teeth. The side of the feed port is installed with labyrinth form plate. The crushing shell connected with the side of the inlet is equipped with sieve plate. The upper sieve plate corresponds to the outlet. The two sides of the discharge port are equipped with arc-shaped chute. The shell is generally wielded with steel plates. The central axis is configurated with convex platform externally and backing pin internally. The outer periphery is equipped with ring retainer with sieve holes. The feed hopper on the top of the shell as well as the upper shell is fixed. Only when changed or repaired does the shell need to be dismantled. In the daily maintenance, the lower part of the shell is fixed to support the whole machine. The grate board and the screen provide auxiliary support for discharging material.
