Products and services

• Pulverizers (Roller Mills) Industrial roller mill pulverizers that grind, dry, and classify material in a single continuous operation, used by mineral processors, power plants, and chemical manufacturers to achieve fine, consistent particle sizing (e.g., 97% minus 200 mesh) with reduced energy and handling costs.
• Impact Dryer Mills Integrated grinding, drying, classifying, and conveying mills that process high-moisture materials (up to 50% moisture) in one continuous, automated operation, delivering a dry classified product at substantially lower power consumption than competing grinding-and-drying setups.
• Industrial Shredders (Ripshear, TF/XL, Primary, Secondary, Nife Hog, Compact Slow-Speed) Heavy-duty shredders — Ripshear slow-speed high-torque disc cutters, Top Feed (TF) and XL Shredders, Nife Hog, primary and secondary shredders, and the compact slow-speed shredder — engineered to reduce bulky, fibrous, or hazardous waste materials for recycling, secure destruction, and downstream processing operations.
• Roll Crushers Single and double roll crushers with heavy-duty construction and a fixed crushing surface distance for consistent product sizing, suited to moderate reduction applications in industrial minerals, chemicals, and agricultural processing.
• Air Classifiers Air classification equipment that separates ground materials by particle size in line with the grinding process, enabling precise product sizing without additional screening steps.
• Impact Crushers (Willpactor, Reversible Nuggetizer Crusher, Reversible Impactors, Willpactor II) Primary and secondary impact crushers with reversible rotors for high-capacity mid-air impact size reduction of rock, aggregate, and minerals, with the Reversible Nuggetizer Crusher handling up to 2,400 tons per hour on limestone and Willpactor units sized for 44–72 inch rock feed.
• Hammer Mills (Type NF/GA, Meteor, Rocket, Type GP, Slugger, High Tonnage, Reversible, Rigid Arm Breakers, Ring Crushers, Traveling Breaker Plate Mills) A broad family of hammer mills — including Type NF/GA heavy-duty, Meteor, Rocket, Type GP general purpose, Slugger Crushers, High Tonnage, Reversible Hammer Mills, Rigid Arm Breakers, Ring Crushers for metal turnings, and Traveling Breaker Plate Mills for wet/sticky clays and bauxite — providing industrial particle size reduction across mining, agriculture, recycling, battery, and biomass applications.
• MineSizer Primary Crusher Heavy-duty run-of-mine primary crusher with dual rotors and an automated control panel with rotor reversal for unjamming, reducing material up to 60 inches in diameter down to 10–12 inches in one pass at 500–2,000 tons per hour for mining and quarrying operations.
• Self-Cleaning Rotary Airlock Valve Dual-rotor rotary airlock valve with a secondary wiper rotor that cleans out the main rotor pockets, designed for severe-duty applications with wet or sticky materials such as coal, pet coke, and clay in completely sealed, dust-eliminating service.
• Forest Products Equipment (Chip Hog, No-Nife Wood Hogs, Horizontal Feed Hogs, Rotary Disc Screens) Dedicated wood and forest products equipment — including the Chip Hog wood chip grinder combining primary and secondary hammer mill capabilities, No-Nife Wood Hogs for bark and pulpwood, Horizontal Feed Hogs for long wood scrap, and Rotary Disc Screens for separating wood, municipal, and industrial waste components — sold to pulp mills, sawmills, biomass energy operations, and wood product manufacturers.
• Steel Apron Pan Conveyors, Apron Pan Feeders, and Feeder Breakers Heavy-duty material handling equipment, including steel apron pan conveyors for extra heavy-duty transport, apron pan feeders for controlled crushing-circuit feeding, and feeder breakers that combine feeding and crushing for mining and quarrying operations.
• Coal Pulverizers for Solid Fuel Combustion Vertical roller mill and direct-fired roller mill coal pulverizers for solid fuel combustion in power plants, processing coal and petroleum coke to the consistent particle sizes required for efficient combustion in coal-fired utility and industrial boilers.
• Limestone Prep Systems for Fluid Bed Combustors Limestone grinding and crushing systems engineered for Circulating Fluidized Bed (CFB) combustors, enabling direct dry-sorbent injection of lime or limestone for flue gas desulfurization in coal-fired power plants and industrial CFB units.
• Custom Fabrication, Machining and Repair Services Custom fabrication, machining, and repair services that complement Williams' standard product catalog, providing customer-specific parts manufacturing, equipment repairs, and specialized industrial equipment solutions for clients with unique size reduction or material handling needs.
