BLACK SHIELD Surface Hardening




LST 65°
Inclined Conic Holes SCREENS
Our conic hole screen has a unique 65° angle perforation, allowing for faster grinding than traditional round or conical hole screens. Micro ribs in the orifice profile ensure effective spraying of the processed product. Lestoque screens feature a revolutionary surface hardening technology, increasing durability by up to 300% compared to typical models. These characteristics significantly save expenditures and maintenance time.
• Less obstruction of holes.
• Better pulverization of the ground product.
• Increased mill productivity.
• Reduction of maintenance intervals.
• Greater durability.

Why upgrade from traditional Round Hole to advanced Conic Hole screens?

Round Hole Drawbacks
Inefficient Legacy
Traditional round hole screens, with flat, non-protruding surfaces, cause grains to bounce, delaying expulsion. This produces uneven particle sizes and lowers hammer mill efficiency. Their outdated structure slows processing, reduces output quality, and fails to meet modern industrial standards for precision and productivity.

Conic Design Innovation
Advanced Screening Technology
Precision-engineered conical perforations and surface hardening treatment increase hole border cutting efficiency. They are optimised for grain milling and pharmaceuticals, eliminating clogging, improving material flow, and providing superior pulverisation, delivering in consistent, high-quality output trusted by huge organisations.

Conical Edge Advantage
Superior Grinding Performance
The 65° conical bore actively slices grains, enhancing hammer mill grinding efficiency. Unlike round holes, it prevents bouncing, enabling rapid, smooth material passage. Its cutting edges ensure finer pulverization and uniform particle sizes for cereal milling, plastic recycling, and pharmaceuticals, delivering unmatched precision.









Lestoque’s hammers for hammer mills, forged from premium hardened steel, deliver powerful pulverization through rapid rotor impacts. In the grinding chamber, these hammers strike materials, breaking them into fine, consistent particles that pass through screens for precise sizing. Designed for industries like cereal milling and pharmaceuticals, they ensure efficient, high-quality output. Their robust construction enhances grinding performance, complementing Lestoque’s advanced screens to meet demanding industrial standards with reliability and precision across diverse applications.
Lestoque’s hammers are crafted using select steels and state-of-the-art anti-abrasion surface hardening, building on years of research from mill screen technology. Each hammer is individually weighed and meticulously balanced to ultra-tight tolerances, ensuring vibration-free operation. Rigorously tested and certified by leading global organizations, they guarantee exceptional durability and performance. Paired with Lestoque’s conic hole screens, these hammers optimize hammer mill efficiency, delivering unmatched reliability for industries like cereal milling, pharmaceuticals, and plastic recycling.
