What West Salem Machinery Company does

West Salem Machinery Company (WSM), founded in 1947 in Salem, Oregon, manufactures heavy-duty industrial grinding, screening, and material processing equipment for wood, biomass, and organic feedstocks. Its core product line spans four grinder families (horizontal, vertical, low-RPM, and hopper-fed grinders) with throughput from 1 to 150 tons per hour, complemented by hammermills for fine particle sizing, Super Shredder hybrid mill/grinder units, a full screen portfolio (disc, oscillating, vibrating, and proprietary Titan Trommel), soil preparation equipment (Coir and Moss Breakers), conveyor/metering systems, and an Automated Bale Processing System targeting SAF/biofuel feedstock. Equipment is all-electric and stationary, marketed on lower total cost of ownership versus diesel alternatives (claimed $0.15 vs $0.41 per cubic yard grinding cost) and on 25+ year service life. WSM sells direct via enterprise field sales, inside sales, regional US coverage, and an Asia/Oceania agent, supported by trade-show marketing and a parts/service aftermarket. Its customers are large industrial enterprises across biomass power, sawmills, pulp and paper, construction and demolition recycling, soil and mulch, pellet feedstock, and emerging SAF/biofuel verticals. Since July 2023, WSM has operated as a separate division within the Sweden-based Bruks Siwertell Group conglomerate, which provides expanded global reach while the WSM brand, engineering, and manufacturing remain in Salem, Oregon. Leadership includes founder great-grandson Mark Lyman as President, with a recently refreshed executive team including COO Kirk Morton and VPs of Sales.

Core offering

West Salem Machinery designs, manufactures, and services heavy-duty industrial grinding and screening equipment used to process wood waste, biomass, peat, and soil into finished size classifications. Its product line spans horizontal and vertical grinders, hammermills, shredders, multiple screen types, and ancillary material-handling/automated bale-processing systems tailored for pulp, paper, sawmill, biomass-energy, mulch, and peat-processing operations.

Product overview

West Salem Machinery (WSM) offers a comprehensive portfolio of industrial grinding, screening, and processing equipment designed for wood, biomass, and organic materials. The core product line centers on four main grinder types: Horizontal Grinders (including the 2432 and 3232 models), Vertical Grinders, Low RPM Grinders, and Hopper Fed Grinders—all featuring all-electric stationary designs. Complementing the grinder line are Hammermills for fine particle sizing, Super Shredders for hybrid shredding/milling applications, and a complete screen portfolio including Disc Screens, Oscillating Screens, Vibrating Screens, and Titan Trommel Screens. WSM also provides specialized Soil Equipment (Coir Breaker and Moss Breaker) for peat moss and coir processing, plus complete Systems integration with Conveyors and Metering Bins, and an Automated Bale Processing System for SAF/biofuel feedstock preparation. All products are engineered for industrial applications in biomass, sawmills, pulp/paper, C&D recycling, compost, and soil/mulch industries, with a focus on all-electric solutions for reduced operating costs and environmental compliance.

Functional benefit

Products and services

• Horizontal Grinders Heavy-duty horizontal-feed grinding machines that process bulky wood, biomass, bark and peat feedstocks into controlled particle sizes for industrial processors and sawmills.
• Vertical Grinders Vertical-shaft grinding machines designed for size reduction of wood and biomass materials, suited for industrial processors handling large-volume feedstock.
• Low RPM Grinders Low-rotational-speed grinding equipment for tough size-reduction jobs, used in industrial applications where reduced fines and steady torque are required.
• Hopper Fed Grinders Hopper-fed grinding machines that allow continuous gravity-fed material entry, suited to high-volume industrial size-reduction lines.
• Hammermills Impact-type hammermill grinding equipment that pulverizes wood, biomass and similar feedstocks using high-speed swinging hammers, for biomass, mulch and pulp-wood processors.
• Super Shredder Heavy-duty industrial shredder for primary reduction of oversize wood, biomass and bulky material prior to further grinding or screening.
• Disc Screens Disc-type screening machines that classify processed wood, peat and biomass material into size fractions, used by industrial processors for product sizing.
• Oscillating Screens Oscillating-motion screens for fine classification of mulch, peat and biomass materials by particle size in industrial production lines.
• Vibrating Screens Vibrating screens that separate processed bulk material into size fractions based on vibration-induced motion, serving wood, biomass and mineral-processing operations.
• Titan Trommel Screens Rotating-drum trommel screens branded as Titan for heavy-duty classification and separation of bulk biomass and wood material in industrial applications.
• Coir Breaker Specialized machine for breaking apart coconut coir and similar soil-blending inputs, used in soil-mix production for horticulture and growing-media plants.
• Moss Breaker Machinery designed to break down and process peat-moss and similar growing-media inputs into a usable, blended form for industrial soil-mix producers.
• Systems (Conveyors, Metering Bins) Engineered material-handling systems including conveyors and metering bins designed to feed and move material through industrial size-reduction and screening lines.
• Automated Bale Processing System Automated system for breaking down baled raw materials into processing lines, intended to reduce manual handling at industrial processing plants.

Direct peers

• Vermeer Corporation: Privately held industrial equipment manufacturer producing horizontal and tub grinders, chippers, and screening equipment used across biomass, recycling, and forestry — overlapping head-to-head with WSM's horizontal grinder, hammermill and screen lines for sawmill and C&D customers.
• Morbark: Morbark (an Alamo Group brand) makes industrial grinders, chippers, and whole-tree chipping equipment for the forestry, biomass, and recycling markets, competing directly with WSM's horizontal/low-RPM grinders in sawmill and chip-handling applications.
• Bandit Industries: Independent US manufacturer of hand-fed and whole-tree chippers, grinders, and shredders serving tree-care, logging, and recycling customers; competes directly with WSM grinders and shredders in the wood/biomass size-reduction market.
• Rotochopper: Specialty grinder manufacturer focused on grinding equipment for wood waste, biomass, colored mulch, and animal bedding — directly comparable to WSM's horizontal/vertical grinders and hammermills serving overlapping end-customers in mulch, pellet and C&D segments.
• Vecoplan: Manufacturer of industrial shredders, grinders, and screening equipment for wood, biomass, plastics, and waste streams; competes head-to-head with WSM's shredders, hammermills, and screening systems in size-reduction applications.
• Komptech: European-based manufacturer of shredders, screeners, and wind turners for green waste, wood, and biomass processing, with growing North American presence directly competing with WSM in C&D and compost/biomass size-reduction equipment.
• Untha: Austrian manufacturer of industrial shredders and size-reduction equipment for wood, biomass, and waste streams; competes with WSM Super Shredder and hammermill lines in heavy-duty shredding and primary reduction of biomass and waste feedstocks.
• DuraTech Industries (Haybuster): Manufacturer of Haybuster tub grinders and a range of horizontal grinders aimed at agricultural residue and biomass applications; overlaps with WSM's low-RPM and horizontal grinder offerings in ag-biomass and C&D wood-processing markets.

Broad incumbents

• Terex Environmental Equipment (CBI / Magnum): Terex's environmental equipment group (CBI horizontal grinders, Magnum chippers, shredders) operates as a large diversified incumbent with broader portfolios than WSM, but offers overlapping grinder technology to the same pulp/paper, biomass and C&D customers.
• Astec Industries: Public diversified industrial manufacturer with material-processing equipment (wood/forestry, mineral processing, infrastructure) that overlaps with WSM in size-reduction and screening, but does not specialize in stationary all-electric wood/biomass grinding.
