Significant technical progress has been made in the transport of bulk materials in the last several years. The advantages of our Eco Series come from the special viscoelastic properties of the pulley cover. Our Eco Series also supports global climate sustainability objectives by enabling energy savings and a reduction of greenhouse gas emissions.
The next step to improved conveyor efficiency is the reduction of power required to operate these high-performance systems. Just as some tires provide lower rolling resistance depending upon their construction and compounds, a conveyor belt can also be designed to provide lower resistance as it rolls over the support idlers.
The power required to operate a typical conveyor belt has been studied, both theoretically and dynamically. As the belt passes over an idler, the pulley cover rubber passes through a compression/rebound cycle that absorbs power. It has been determined that on long center horizontal conveyors, the rolling resistance power loss due to the indentation effect can reach 61% of the total system power.
Systems that use our Eco series pulley cover compounds will reduce power consumptionby at least 15%. Our Eco Extreme compound will reduce energy consumption up to 30%*. These savings are realized year after year, resulting in an overall reduction in operating costs.
For example, if your energy costs are $1 million per year, a potential 30% savings with Eco Extreme represents a savings of $300,000 compared to other compounds. Over ten years, this can add up to a savings of $3 million or more depending on your operation.
