Crumb Rubber System - Stages 1-4 | CM Shredders

Stage 1 – Shredding - The reduction of whole tires down to shreds or chips utilizing A CM Primary Shredder.


Stage 2 – Steel Liberation & Removal - Tire shreds from a CM Primary shredder are introduced to the CM Liberator which removes the steel wire from the rubber fraction. Further reduction of the shred into ground wire-free rubber feedstock is accomplished. Clean steel is separated for resale. Fiber is extracted using a dust collection/air system.


Stage 3 – Granulation - The Granulator can accept 25 mm `{`1“`}` wire-free crumb rubber and process it down to 4 mm rubber granulate. At this stage, screens are used to size the material and an air system is used to extract the fiber.



Stage 4 – Milling & Screening - The Dual Drive Crackermill will accept 4-8 mm crumb rubber and further process it into fine powders ranging from 10 to 80 mesh. The final stage in tire recycling, this stage produces clean rubber powder.


Rubber Mulch - Used for landscaping


Benefits: Deters insects, drains well, water gets to the plants, long lasting, does not fade, blow away or disintegrate, reduces weed growth and reduces soil erosion.
Playground and Equestrian Footing


Used as a loose cover for playgrounds or horse arenas.


Benefits: Softer cushion for falls, long lasting, does not blow away, deters insects, comes in many colors!
Wire Free TDF - Used for waste to energy, pyrolysis or gasification applications


Used as an alternative to fossil fuels. Used primarily in cement kilns, steel mills power plants and pulp and paper mills. Size range: 1″ to 4″ [25 mm to 100 mm].


Benefits: Burns hotter and cleaner than coal or petcoke.
TDA – Tire Derived Aggregate


Used as a light weight fill material for civil engineering projects such as: back fill, slope stabilization, embankments, drainage and sound abatement. Size range: 100mm to 400mm [4″ – 16″].
