<p>The screen drum and rotor of a pressure screen are long-running wear parts; maintenance should be preventive. Establish a regular inspection routine focusing on screen-surface wear, rotor dynamic balance and fastener condition.</p><p>In daily operation, keep feed consistency and flow within the process range to avoid impurities damaging the screen surface; stock sufficient spare wear parts to significantly shorten replacement downtime.</p><p>Standard preventive maintenance extends component life, stabilizes product quality and reduces downtime losses from sudden failures.</p>
