Hydraulic Pumps on the Krumbuster Help Revolutionize Crumb Rubber Production

Hydraulic Pumps on the Krumbuster Help Revolutionize Crumb Rudder Production Rubber Recycling Equipment Hydraulic Pump and Power Systems DivisionEco Green Equipment, a tire recycling equipment manufacturer, was looking to meet the stringent demands of the crumb rubber and rubber powder markets. Due to rubber use in artificial turf, playground surfaces, and other applications, crumb rubber and rubber powder are in greater demand with higher quality expectations.

Existing cracker mill technology could produce crumb rubber in reasonable quantities. However, due to their friction ratios, mills could not produce it at a high enough quality or a low enough mesh crumb rubber. As a result, Eco Green wanted to achieve both volume and high quality of crumb rubber in one machine. To fill this gap in the market, Eco Green’s Krumbuster was created.

The following design specs were set for Eco Green Equipment’s Krumbuster:

  • Produce up to 4,000 pounds an hour of smaller than 6 mesh crumb rubber

  • Produce up to 2,000 pounds of smaller than 30 mesh rubber powder with the same machine and set-up

  • Decrease horsepower usage by 20% or more

  • Achieve a smaller equipment footprint than traditional mills

  • Create a high-performance hydraulic grinding mill that remains highly responsive with:

    • Changes in friction ratios

    • High shock loads

    • Constant changes in pressure and pressure spikes

Solution

With Eco Green Equipment collaborating with Parker Hydraulic Pump and Power Systems (HPS) and a Parker distributor, a high-performance, reliable hydraulic system for the Krumbuster was designed. Key hydraulic components for the Krumbuster, included Parker P24 and P6 Gold Cups and T6 Vane Pumps.

The Gold Cup pumps were especially critical for this demanding application and the ability to maintain them through authorized repair centers throughout the world.

 

 

Results

The results of the Krumbuster’s hydraulic system have revolutionized rubber mill technology. The Krumbuster’s higher production and quality in comparison to traditional mills has been achieved, along with a smaller equipment footprint and less energy consumption.

Parker’s Hydraulic Pump and Power Systems Division has been designing pumps and transmission for over 50 years. The division is the result of the Parker piston pump business's acquisition of Denison Hydraulics and the merger with the Parker Oildyne Division. These two businesses combined have extended Parker's product offering to include the quality compact hydraulic products and systems the division has been pioneering since 1955.
