Take Tyre Recycling Beyond Primary Shredding

The Saturn Grizzly range from Granutech-Saturn Systems provides heavy-duty secondary grinding and granulation for tyre recycling operations looking to process pre-shredded tyres into smaller, cleaner and more consistent rubber fractions.

Designed to operate downstream of primary tyre shredding, the Grizzly uses a single-rotor cutting system to further reduce tyre material while liberating embedded steel. This creates a more uniform rubber product, improves magnetic separation and prepares material for further granulation, refining or end-market applications. Granutech-Saturn reports that this mid-stream processing can consistently produce rubber better than 95% free of steel.

From TDF to Higher-Value Rubber Recovery

Primary shredding to produce TDF is only the beginning of the tyre recycling process. As markets develop for recovered rubber, further processing can transform tyre material into rubber crumb for use in new products, creating higher-value recovery pathways and supporting greater circularity for end-of-life tyres.

Within a Waste Initiatives tyre recycling system, Barclay primary shredders can provide the initial size reduction, with Saturn Grizzly technology added downstream where further reduction and steel liberation are required.

The Grizzly reduces pre-shredded tyre material to a smaller and more consistent particle size. This helps expose and separate tyre wire while producing a controlled rubber fraction that can either become an end product or feed additional processing equipment.

The Grizzly is a mid-stream processing stage, producing cleaner, more uniform feed which improves downstream granulator performance and reduces wear.

Saturn Grizzly Model 80

Proven Tyre Grinding

The Saturn Grizzly Model 80 (M-80) is a heavy-duty tyre grinder/granulator designed to further reduce shredded tyre material while liberating steel from the rubber fraction.

Its completely hardfaced rotor incorporates a star rotor design with 50 rotary knives working against 10 stationary knives. The Model 80 combines this cutting arrangement with replaceable screens to provide controlled material sizing and reliable secondary tyre processing.

Key Features

• Up to 5 tons per hour throughput
• Heavy-duty single-rotor grinding system
• Completely hardfaced rotor
• 50 rotary knives and 10 stationary knives
• Replaceable screens for controlled sizing
• 3,500 sq. in. screening area
• Replaceable AR500 housing liners
• Severe-duty gearbox
• Hydraulic lid opening
• Infeed and discharge hoppers
• Optional water spray and deluge system
• Rectangular knife design

Saturn Grizzly Super 80

High-Throughput Secondary Tyre Grinding

For higher-volume tyre recycling operations, the Saturn Grizzly Super 80 (S-80) provides increased power, torque and processing capacity.

The Super 80 is a high-performance secondary grinder designed specifically for high-throughput tyre recycling.

The Super 80 uses an 80-inch hardfaced rotor fitted with 80 rotary knives working against 17 stationary knives. A two-piece screen design provides a large screening area, while the serrated knife arrangement, higher-capacity gearbox and 400 HP drive provide the capacity required for demanding continuous tyre processing.

Optional configurable screens produce smaller, more consistent material to support downstream processing.

Key Features

• Up to 10 tons per hour throughput
• 400 HP drive
• 18,600 ft-lbs of torque
• 80-inch hardfaced rotor
• 80 rotary knives
• 17 stationary knives
• Serrated knife design
• Two-piece screen design
• 3,500 sq. in. screening area
• Replaceable AR500 liners
• Higher-capacity gearbox
• Hydraulic lid opening
• Optional water spray and deluge system
• Optional ram feed design

Improve Steel Liberation & Rubber Quality

One of the key roles of the Saturn Grizzly is not simply making tyre material smaller. It is creating the conditions required for more effective rubber and steel separation.

As tyre chips pass through the grinder, further size reduction helps liberate embedded tyre wire. Producing a smaller, more uniform fraction also improves the effectiveness of downstream magnetic separation.

Grizzly grinders can produce rubber consistently better than 95% free of steel. The resulting cleaner material entering downstream granulation can increase granulator blade life by as much as 300%, depend on the application and system configuration.
