SUMMARY

The discussion focuses on calculating the appropriate hydraulic motor for a shredder machine designed to turn a 2-1/2 inch diameter shaft with a length of 30 inches and 15 rotating chewing disks. The operation involves shredding soils and clay at a rate of 40 cubic yards per hour, with a density of approximately 80 lb/ft³. Additionally, a No. 80 drive chain is utilized with a sprocket size ranging from 12 to 19 teeth. Understanding the power consumption related to the shredding process is crucial for selecting the right hydraulic motor.

PREREQUISITES
  • Understanding of hydraulic motor specifications and calculations
  • Knowledge of soil and clay density and its impact on power requirements
  • Familiarity with drive chain mechanics, specifically No. 80 drive chains
  • Basic principles of torque and rotational speed in machinery
NEXT STEPS
  • Research hydraulic motor sizing calculations for shredding applications
  • Learn about torque requirements for different materials, specifically soils and clay
  • Investigate the impact of sprocket size on motor performance and efficiency
  • Explore power consumption analysis for hydraulic systems in heavy machinery
USEFUL FOR

Engineers, machine designers, and operators involved in the design and optimization of shredding machines, particularly those working with hydraulic systems and material processing.

Would like to know how to calculate which hydraulic motor to turn a 2-1/2 dia shaft at a length of 30",with 15 mounted rotating chewing disks for a shredder machine. We are shredding soils and clay at about 40 yds/hr. we are also using a No. 80 drive chain on 12 to 19 tooth sprocket too.


Any ideas welcome.

Thank you

Well the soil and clay shredding operation is the bit which is going to consume the power, so you need more details around this aspect.

Is this an existing machine?
 
Not existing yet.

ok- Soils are about 80lb/ft3 density and loading is, well 40 yd3/hr.

what other info?
