Guide to selecting screen mesh for diabase 130 tph

1. Understand Diabase Abrasiveness and Screening Goals
Diabase is a hard, dense igneous rock with high abrasiveness (Mohs hardness 6-7). When following a guide to selecting screen mesh for diabase 130 tph, the first decision is mesh material. Standard woven wire mesh made of mild steel may wear through in 40-60 hours of diabase screening. Instead, opt for oil-tempered or high-carbon steel wire – or better yet, stainless steel (Type SS304 or SS316) for longer life. For the toughest applications, polyurethane screen panels with 35-40 Shore D hardness are widely used because they offer 3-5 times the wear life of steel wire. However, polyurethane requires a larger open area to maintain 130 tph, so you must balance durability with throughput. Actual screen life varies with feed size, moisture, and tonnage. Always test multiple media or consult OCP engineers for site-specific recommendations.

2. Matching Aperture Size and Wire Diameter
A critical part of any guide to selecting screen mesh for diabase 130 tph is choosing the correct aperture (opening size) and wire diameter. For typical diabase aggregate specifications (0-5mm, 5-10mm, 10-20mm, 20-40mm), you will need multiple deck screens. On the top deck (40mm), use square openings with 6-8mm wire diameter – thicker wire resists wear but reduces open area. On the middle deck (20mm), 4-5mm wire is common. On the bottom deck (5mm or 10mm), a finer wire (2-3mm) is acceptable, but expect more frequent replacement. For 130 tph, ensure the total open area per deck is at least 40-50% – lower percentages will choke the screen and reduce capacity. In Uzbekistani quarries (e.g., near Tashkent), many operators successfully use self-cleaning mesh (Type SQ) with slightly elongated openings to prevent blinding from diabase fines. *Production data are based on dry diabase (density 2.8-3.0 t/m³).

3. Screen Panel Type and Tensioning System
Another factor in this guide to selecting screen mesh for diabase 130 tph is the panel design. Hook-strip woven mesh is cost-effective but requires frequent re-tensioning. For diabase, modular polyurethane panels with built-in tensioning frames offer more consistent performance – they do not sag or loosen, and they reduce noise. If you use woven wire, choose a double-crimped or lock-crimp weave – these hold wire intersections tighter under vibration. Also, consider the screen deck support: rubber or polyurethane balls under the mesh (ball deck trays) can help keep diabase fines from blinding the apertures. OCP Mechanical Company’s Type S-2470 vibrating screen can be equipped with quick-change modular panels, reducing downtime for mesh replacement from hours to minutes. Machine efficiency and cost-effectiveness are our design goals, but actual results depend on proper feed distribution and tensioning.

4. Practical Tips to Extend Screen Life at 130 tph
To get the most from your selection, follow these operational guidelines:

• Feed the screen evenly across the full width – narrow feeding wears out the center of the mesh quickly.

• Inspect mesh daily for broken wires or holes – a small tear will rapidly enlarge under diabase vibration.

• Use a lower vibration amplitude (6-7mm) for polyurethane than for steel wire (8-9mm) – polyurethane is heavier and requires less energy.

• Replace mesh before it loses tension – loose mesh slaps against supports, causing premature failure.
  Always keep spare screen panels on site. OCP recommends stocking one full set for every 500 operating hours.

5. Why OCP Helps You Select Cost-Effective Screen Media
