A sieve plate is arranged in the impact crusher to screen out the crushed limestone particles meeting the production requirements. However, due to the stickiness of limestone, the main component of limestone is calcium carbonate, and the powder form of calcium carbonate exhibits stickiness under certain conditions. For example, after absorbing moisture, quicklime becomes calcium hydroxide, which has strong stickiness. Therefore, during the crushing process, limestone particles are first stuck in the sieve holes of the sieve plate or the sticky powder is adhered to the inside of the sieve holes of the sieve plate. Therefore, the commonly used impact hammer crusher needs to be disassembled to disassemble the sieve plate, then the sieve plate is cleaned, and then the sieve plate is installed in the impact hammer crusher. It is time-consuming and laborious, and the disassembly and reinstallation operation needs to be carried out after stopping the machine, which will delay the time and reduce the crushing efficiency.
