Fodamon Machinery is proud to showcase how we produce custom roll skins for double roll crushers, an essential component for crushing performance and durability. In this article, we walk you through the manufacturing journey—from foam modeling to machining, inspection, packaging, and global shipment.
Our process ensures precision, extended service life, and cost-efficiency for clients in sand-making, mining, and cement industries across the world.
🏭 Manufacturing Process: From Foam Model to Finished Roll Skins
The production of roll skins involves a technically advanced lost foam casting process, ideal for complex shapes and high-volume demands. The key stages include:
- Foam Model Creation: Our skilled technicians craft a full-size model from high-density EPS (expanded polystyrene) to replicate the final roll skin’s geometry.
- Coating & Drying: The foam model is coated with refractory material and dried to ensure surface quality during casting.
- Sand Filling & Molding: The model is buried in dry sand and compacted using vibration.
- Molten Metal Pouring: As metal is poured, the foam vaporizes and is replaced by molten alloy, forming the final casting.
- Cooling & Cleaning: The solidified roll skin is extracted, cleaned, and prepared for finishing.
- Precision Machining: The casting is lathed, milled, and ground to ensure exact tolerances and concentricity.
- Inspection & Heat Treatment (optional): Each piece is inspected and heat-treated (if required) to improve wear resistance.
- Packaging & Shipping: Protective wrapping, custom wooden crates or steel frames, and detailed labels ensure safe international delivery.
We’ve documented this process through detailed workshop photos showing every step—from foam modeling to final shipment.
🌍 Major Export Countries and Application Scenarios
🇮🇳 India
Widely used in limestone crushing for cement plants across Gujarat and Andhra Pradesh. Our roll skins are popular for their durability and stable performance in dusty environments.
🇵🇭 Philippines
Extensively adopted for river pebble sand-making lines and construction waste recycling. Double roll crushers help clients meet high aggregate demand with better particle shape.
🇮🇩 Indonesia
Deployed in coal gangue and shale crushing, particularly in mining regions. Our high-chromium roll skins provide excellent wear resistance during 24/7 operation.
🇺🇿 Uzbekistan
Used in dolomite and basalt processing lines. Our crushers support secondary crushing in sand plants, reducing oversized aggregates and improving fine content.
🇵🇰 Pakistan
Employed in granite and quartz sand production, especially in high-strength concrete applications. Our roll skins ensure consistent feed size and reduced maintenance downtime.
🇳🇬 Nigeria
Adopted in iron ore tailings recovery and limestone aggregate plants. Our wear-resistant roll skins are favored for minimizing shutdowns and extending service cycles.
🇪🇬 Egypt
Utilized in dolomite and clay processing before cement grinding, often in dry climates. Our customized roll skins maintain performance under variable thermal loads.
🪨 Suitable Rock Types for Double Roll Crushers
Double roll crushers from Fodamon are engineered to handle various medium-hard and soft materials. Here are some commonly crushed materials:
- Limestone – Ideal for cement and lime production. Our roll skins provide smooth crushing with minimal fines.
- River Pebbles – Crushed to make construction-grade sand. Roll crushers maintain particle shape and gradation.
- Shale / Coal Gangue – Used in brick plants and fuel applications. Efficient reduction with minimal clogging.
- Dolomite – For glassmaking and metallurgical uses. Requires wear-resistant surfaces.
- Quartz / Granite – Demanding materials that need high-strength roll skins for controlled crushing and low energy loss.
- Clinker – Pre-grinding application in cement industry, reducing load on vertical mills.

📦 Packaging & Delivery Process
Each set of roll skins is:
- Carefully wrapped with anti-corrosion film
- Placed on custom steel frames or wooden crates
- Labeled with clear product ID and inspection tags
- Documented with photos and shipment checklists
This ensures our customers receive their order in perfect condition—ready for installation.
