Drive Shredding Trucks
Customized to each application to meet particle and throughput requirements
Things to Consider for Solutions
• Material to be Processed
•
•
•
•
SSD’s with or without cases
HDD’s, server and non-server
Hand held devices (without batteries)
Circuit boards
• Throughput requirements (drives/hr
or lbs/hr)
• Destruction requirements
• Minimum particle size
• Strips or Particles
• Certifications
• Truck
• CDL vs Non-CDL
• Auxiliary Generator vs PTO
• Storage and weight requirements
• Safety
•
•
•
•
Ventilation w/ HEPA filtration
Machinery Guarding requirements
Fire protection
Explosion Protection
• Flameless vents
• Isolation valves
Truck
CDL (GVWR’s of 26,000 lbs and up) vs. Non-CDL (GVWR’s of 25,999 lbs)
CDL Pros
CDL cons
Larger weight capacity
Larger space for equipment and storage
CDL driver needed
Higher operational cost
Higher cost of truck
Non-CDL Pros
Non-CDL cons
Can be operated by anyone who has a
driver license
Cheaper cost of truck
Weight limit of under 26,000 lbs
Less room for equipment and storage
Cheaper operational cost
Weight is a constraint in the design – truck weighs ≥15,000 lbs. Less than 9,000
lbs for shredding equipment, storage, generator, dust collector, fire protection
equipment, HVAC, liftgate, curb side door, etc

Power Options
• PTO driven underdeck generator
•
•
•
•
•
Advantage: less weight, less maintenance
Easier to add more KW for larger shredder
Use less gallons per hour
Less overall emissions
New truck required for PTO transmission
• Tier 4 Generator
• Option for used trucks without suitable PTO connections
• Reduces available freight carrying capacity and floor space
• Enclosure built around the generator
Box enclosure
Conveyor fed
Shredding System Options
• Shredder shafts and conveyor can be driven by the
same motor for efficiency
• Portable – Equipment on wheels and locks into truck
• Full machine guarding exceeding OSHA requirements
• Custom 2 piece box cover that nests with conveyor
discharge to contain dust
• Chevron style belting and rubber side skirting
• Special drop out area on conveyor pan to absorb
shock and reduce belt jams
Shredding System Types
Twin Shaft Shredders
- Product uniform width strips
Four Shaft Shredders or Mills
- Produce uniform particle sizes in all
- Tend to have higher throughput for a given
horse power
- Lower noise and dust levels
1.5” Strips
directions
- Required more horsepower for a given
throughput

Throughput will always be
dependent on
• The type of drive (form
factor)
• Desired particle size
• Split machine – dividing
energy
• Operator influences
• Cutter condition
• Shredder rpm
• HP, Generator KW (torque)
We customize the shredder for the exact application – tables above are for
Shredder options, brands
Split chambers
2-shaft
4-shaft
Hammermills
Multiple
shredders
VFD advanced
drives
Meter feeding
We choose the best shredder for your exact application
Ventilation and Safety
• Ventilation Only – Standard dust
collector/filtration system that collects at
enclosed equipment limiting fugitive dust.
• Ventilation with fire and explosion protection
– Detached dust collector with HEPA Filter,
magnehelics, passive isolation valve, and
flameless explosion vent.
• Smoke detectors, fire extinguishers, first aid
kit, eye wash station are available options.
• Dust generated from E-waste shredding can
be explosive.
Box enclosure
Detached
Dust collector
Other Options
• Larger HP shredder 20+
- Feasible if less freight carried and PTO generator.
• Alternate internal truck configurations
- Shredder over box, enclosure
- Isolation wall with door
• Alternative shredder types and brands available
• Cameras, DVR, and Radio
• Custom truck boxes
• Tool kits
• Critical spare parts kits
Conveyor fed
Testing
• Testing will give a baseline
- Known torque values of test shredders at factory
- Adding more HP/RPM on while maintaining
torque will increase throughput
• Need worst case product specification and
samples
• Solutions are available for challenging
applications such as thick server drives.
• Testing is required for rating throughput
Short Hooks
We know shredders.
