If the anti-blocking operations cannot be performed during use, the subsequent use process will affect the screening operation of the pressure screen, thereby reducing the convenience of using the pressure screen. Therefore, we propose a pressure screen for paper processing to solve the above-mentioned problems. Utility Model Content
