Cement & Aggregate Industry Solutions

High-strength chains engineered for the toughest bulk material handling applications

Cement, aggregate, and mining operations demand components that can endure abrasion, heat, impact, and extreme loads.

From quarry extraction and raw material handling to clinker cooling and finished product movement, every chain in the system must work flawlessly — hour after hour, day after day.

 

 

 

That’s why iwis provides engineered chain solutions built specifically for heavy-duty bulk material handling.

Our chains deliver exceptional wear resistance, for safe, reliable conveying across the entire cement manufacturing and aggregate processing industry.

  • Extended service life: Specialized heat-treated and optimized materials reduce elongation and wear, delivering reliable performance over long intervals.

  • Proven performance in bulk materials: Designed for clinker, limestone, gravel, sand, gypsum, coal, and other abrasive media.

  • Custom-engineered to your system: iwis produces a full array of made-to-order chains, including scraper chains, bucket elevator chains, and engineered class assemblies for OEM or retrofit applications.

  • Global engineering, local support: German precision, U.S.-based technical guidance, and responsive regional support to keep your operation running.

Durable, long-life chains that reduce downtime, improve safety, and keep your entire material flow moving efficiently.

German-engineered chain solutions trusted across the world's most demanding heavy-industry applications.

Engineered Class Chains for Cement & Aggregate

 

iwis Engineered Class Chains are designed to handle the heavy shock loads, abrasive environments, and continuous operation found in cement plants, quarries, and bulk material handling facilities. Manufactured with specialized, proprietary heat-treated pins, bushes, rollers and sidebars, these chains deliver exceptional fatigue resistance and reliable conveying performance. A wide range of chains with multiple attachment/pin/roller configurations means iwis can meet your requirements, whatever they may be.

Elevator & Reclaimer Chains

Vertical lifting and heavy-duty reclaiming for abrasive bulk materials

iwis engineered class elevator and reclaimer chains are built to withstand the extreme loads, abrasion, and impact conditions found throughout cement and aggregate processing. Designed for consistent pitch accuracy, high fatigue strength, and stable engagement, these chains deliver long service life in bucket elevators, stockpile reclaimers, limestone and gypsum feed systems, and clinker transfer points. Whether lifting hot clinker vertically or reclaiming compacted bulk material horizontally, iwis elevator and reclaimer chains ensure smooth, reliable operation with minimal downtime.

As an added bonus, iwis can provide many of our ELITE HSP elevator chains in as little as 48 hours from stock.

Drag, Scraper & Apron Conveyor Chains

High-strength conveying for clinker, raw feed, quarry stone, and kiln discharge

iwis drag, scraper, and apron conveyor chains are engineered for severe-duty applications where heavy loads, high temperatures, and abrasive materials demand exceptional strength and wear resistance. Offset sidebar chains like the WHX 6067 offer superior abrasion resistance and lateral stability for drag conveyors, while apron pan conveyor chains reliably carry hot or sharp materials through crushers, coolers, hoppers, and feeders. Manufactured from high-grade alloy steels with specialized heat treatment iwis conveyor chains reduce elongation, extend service intervals, and enhance predictability in bulk-material handling environments.

Featured Products:

  • WHX Heavy-Duty Offset Sidebar Drag Conveyor Chain
  • Apron Pan Conveyor Chains
  • Reclaimer Chains

Large-Pitch & Specialty Conveyor Chains

Custom-engineered solutions for long runs, heavy loads, and specialized material-handling requirements

For unique conveying challenges in cement and aggregate operations, iwis provides large-pitch and specialty roller conveyor chains tailored to specific loads, geometries, and environmental conditions. Outboard and bearing roller chains minimize rolling resistance over long distances or under heavy loads, while inboard roller configurations offer compact strength in restricted spaces. iwis also designs bespoke solutions, such as large-pitch custom roller chains, built to match exact OEM specifications and improve throughput, service life, and reliability across specialized conveying systems.

Featured Products: 

  • Custom Large-Pitch Roller Conveyor Chain
  • Outboard Roller / Bearing Roller Chain
  • Inboard Roller Conveyor Chain
