PU Elastomer Casting Machine for Mining Screen Plates

Product Overview

Specially designed for large-scale production of polyurethane screen plates in mining, metallurgy and coal industries, widely suitable for harsh working conditions such as ore screening, coal screening and metallurgical raw material classification.

This PU cast unit is purpose-built for the large-scale production of polyurethane screen plates used in mining, metallurgy and coal industries. The 2A2B two-component system includes a dedicated wear and impact resistant additive tank, greatly improving the wear and tear resistance of screen plates to withstand harsh mining screening conditions. The system supports flexible switching between MOCA and BDO chain extenders, allowing adjustment of product hardness and strength for different screening scenarios. With large-flow stable pouring (100–1500 g/s), the machine is perfectly suited for large-size screen plate molds, achieving full filling without holes and ensuring uniform product structure. Stable and reliable operation supports mass continuous production, effectively improving production efficiency and yield of mine screen plates. The machine meets the core production requirements of high load, long life and tear resistance for mine screen plates.

Operation Workflow

Raw Material & Additive Preparation

Prepare CPU prepolymer and chain extender (MOCA or BDO) at the target mix ratio (MOCA: 100:10-13; BDO: 100:4-6); load wear and impact resistant additives into the dedicated additive tank.

Tank Loading & Temperature Setting

Load prepolymer into Tank A and chain extender into Tank B; set Tank A to 30-80°C and Tank B per formula (MOCA: 90-115°C; BDO: 25-50°C) for stable metering.

Vacuum Defoaming

Activate the vacuum defoaming system to reach ≤-0.095MPa, removing bubbles to ensure dense, hole-free screen plates with uniform product structure.

Large-Flow Metering, Mixing & Casting

The PLC dynamic metering system dispenses precisely; the mixing head runs at 7000-11000 r/min for homogeneous blending, with large-flow pouring filling large screen plate molds.

Frequently Asked Questions

What mining applications is this machine designed for?
This machine is specially designed for large-scale production of polyurethane screen plates used in mining, metallurgy and coal industries. It is suitable for harsh working conditions such as ore screening, coal screening and metallurgical raw material classification.
How does the machine ensure wear and impact resistance for screen plates?
The 2A2B configuration includes a dedicated wear and impact resistant additive tank. These reinforcing additives greatly improve the wear and tear resistance of screen plates, enabling them to withstand harsh mining screening conditions and extending service life.
What is the pouring rate range and why is it important for screen plates?
The pouring rate is adjustable within 100–1500 g/s. This large-flow capability is perfectly suited for large-size screen plate molds, ensuring full filling without holes and uniform product structure across the entire screen plate.
How does vacuum defoaming benefit mine screen plate production?
The vacuum defoaming system maintains vacuum ≤-0.095MPa, eliminating bubbles and voids from the product. This ensures dense, hole-free screen plates with consistent mechanical properties, critical for withstanding high-impact screening conditions.
Can I adjust the hardness of the screen plates for different ores?
Yes. The machine supports flexible switching between MOCA and BDO chain extenders, allowing you to adjust product hardness and strength to suit different screening scenarios and ore types.
Is this machine suitable for mass continuous production?
Yes. The machine is designed for stable and reliable mass continuous production, effectively improving production efficiency and yield of mine screen plates while maintaining consistent quality batch after batch.
