✅ What is a PU Screen Plate?

A PU screen plate is typically a modular panel or custom-sized flat or curved plate with openings (slots or holes) that allow certain-sized particles to pass through while retaining larger ones. It is mounted on vibrating screen decks or screening machines to classify or dewater materials.

? Key Features

• High wear resistance: Polyurethane is extremely resistant to abrasion, especially in wet and coarse materials.

• Elastic and impact-resistant: Absorbs vibration and impact from materials, reducing equipment damage and noise.

• Anti-clogging: PU’s flexibility allows screen openings to resist blinding (clogging), ensuring consistent performance.

• Corrosion-resistant: PU doesn’t rust and is unaffected by water, chemicals, or most industrial fluids.

• Lightweight: Easier to install and replace than steel screens, reducing labor and structural load.

• Longer lifespan: PU screen plates often last 3–5 times longer than wire or steel screens in many applications.

⚙️ Types of PU Screen Plates

• Modular PU panels – Usually 305×610 mm or 300×1000 mm, designed for modular deck systems

• Tensioned PU screen panels – For hook-screen systems; used like woven wire screens

• Fine PU screens – High-precision openings for fine particle classification or dewatering

• Customized PU plates – For curved screens, rotary drums, or special vibrating equipment

? Opening Types & Sizes

• Round holes

• Square holes

• Slotted (elongated) holes

• Slot width: from 0.1 mm to over 50 mm depending on application

• Opening percentage varies with design

? Common Applications

• Mining – gold, copper, iron ore classification

• Quarry – sand, gravel, crushed stone screening

• Coal preparation plants

• Sand and aggregate washing

• Recycling and wastewater dewatering systems
