Pumps in Hydraulic Systems are Key to Tire Recycling Solution for Mining

Pumps in Hydraulic Systems are Key to Tire Recycling Solution for Mining equipment Hydraulic Pump and Power SystemsMining trucks encounter heavy, frequent loads throughout their life cycle, and replacing their large tires, which could be in the realm of 13 feet or even larger, can occur as much as 4 to 6 times per year. Historically, these massive, worn-out mining tires have been stockpiled, buried, and just abandoned at the mine site. Mining companies face the challenge of what to do with all these old tires. Transporting each tire entirely in-tact is costly and cumbersome due to their scale. Simply leaving the old tires at the mine site, can release toxins into the environment and create a breeding ground for pests, such as mosquitoes.

 

Solution

Eco Green Equipment, a tire recycling equipment manufacturer, identified that the disposable of old mining tires was a worldwide issue and discovered how taxing it was on mining companies and the environment. As a result, they worked to develop the Eco Green Off The Road (OTR) Mining Tire Solution, consisting of three pieces of equipment that provide mining companies with the ability to more easily move and recycle their old truck tires. Now instead of these tires disintegrating and taxing the environment, they are another revenue stream for the mining company.

Premium rubber mulch, used frequently in high-end landscaping and playgrounds, can be lucrative due to its high demand.

Eco Extractor 63 is the second piece of equipment. It removes the steel bead from the large mining tires, which can then be sold and recycled into other steel products.

The third and final piece of equipment is the Eco Shear 63, which reduces the giant buffed and debearded tire into much smaller pieces. The result is a more transportable tire remnant that can be delivered to a rubber recycler or further ground through a tire shredder, such as the Eco Green Giant.

During the development phase for the OTR Mining Tire Solution, Eco Green reached out to their existing partners, including Parker’s Hydraulic Pump and Power Systems (HPS), and a distributor to help in the development of the robust hydraulic systems tailored for the Eco Razor and Eco Extractor.

The result was a hydraulic system substantial enough to support each equipment’s unique requirements, including:

• The Eco Razor’s shock load from the buffing head and saw, which removes the high-quality rubber.

• The Eco Extractor 63’s high-pressure cylinders, unique reverse hook, and auto bead ejector capabilities, which require enough force to cut through remaining layers of steel and rubber into smaller more manageable pieces.

The P1 Series 045 cc pump provides flow to various cylinders used to position the Razor, as the machine works through different areas of the tire. Pumps in Hydraulic Systems are Key to Tire Recycling Solution for Mining  P1PD Pump Hydraulic Pump and Power Systems

 

 

 

 

For the Eco Extractor, the PVplus Axial Piston Pump with variable displacement is designed and optimized for demanding use in heavy-duty industrial applications. In this case, the hydraulic system required an open-loop pump that could handle a 4,000 PSI requirement. With pressure ratings of up to 420 bar and high-speed ratings, the PVplus Axial Piston Pump’s swashplate principle provides high productivity and power density for this application. 

 

Result

Pumps in Hydraulic Systems are Key to Tire Recycling Solution for Mining  PVPlus Hydraulic Pump and Power SystemsBecause Eco Green selected the F12 hydraulic motors for the Eco Razor, the equipment has the capability, efficiency, and longevity to cut through the mining tires’ tough rubber layers on a consistent basis. Parker’s P1 Series 045 cc pump and PVplus Axial Piston Pump also rounded out the offering for this demanding industrial application.

Eco Green currently has five OTR Mining Tire Solutions being manufactured that will be shipping to Canada, USA, Colombia, and Chile over the next few months.
