Polyurethane dewatering screen panel are widely used in coal preparation plants for coal dewatering and classification, but their performance is highly dependent on proper usage and maintenance. Based on actual operating conditions, this article systematically outlines key considerations across five core stages: selection, installation, operation, maintenance, and storage. The selection phase emphasizes precise matching based on coal quality characteristics and screen parameters; installation focuses on standardized procedures and inspections; operation provides guidance on real-time monitoring and load control; maintenance offers periodic upkeep and troubleshooting solutions; and storage ensures material protection against aging. Through comprehensive lifecycle management, this approach significantly extends screen plate lifespan, enhances screening efficiency, and reduces operational costs. This guide serves coal preparation plant operators, equipment managers, and technical engineers to achieve efficient and safe screening operations.

Polyurethane screen panels are known for their high wear resistance and long service life, making them the preferred choice in modern mining and aggregate screening. However, poor field maintenance practices can drastically shorten their lifespan and increase replacement costs.

This article highlights the most common maintenance mistakes that cause premature wear or failure — such as improper installation, uneven tensioning, and neglecting regular inspection. It also explains how mixing old and new panels or using the wrong aperture size can create stress points, uneven loading, and reduced screening efficiency.

Proper maintenance practices are key to ensuring performance longevity. Simple measures like maintaining deck cleanliness, checking for loose bolts, monitoring for cracks or delamination, and storing screens correctly can add months of service life and significantly reduce operational downtime.
