The Schenck Process Alternative Fuel Feeding system for cement manufacturers provides the environmentally friendly solution. Key to the system is the ability to 
meter waste materials such as PET bottles, saw dust, tires, paper, wood chips, rice, bone meal, and others to the main burner and calciner of a cement kiln reducing the need for non-renewable fossil fuels such as coal.
Schenck Process offers a modular alternative fuel feeding system that consists of a docking station with live bottom bin for semi-trailers, chain conveyor, weighfeeder, blow-through rotary feeder, rotary piston blower, pneumatic conveying line, and measuring, control, and supervisory electronics for continuous operation.
The semi-mobile system features a small footprint so no special foundations are necessary and can be set up on virtually any firm surface where a truck can drive. Placement of the system is possible next to the kiln or up to a distance of 300 ft. from the burner. Dismantling and reconstructing in any other part of the plant can be done within a short period of time.
Critical features of the system include precise accuracies, a wide range of feed rates, and consistent flow of material to the kiln. Accuracies of ±1 percent within a range of 1:20 and feed rates from 0.25 to 10 tph help produce an even and pulsation free conveying of fuel through the blow-through rotary feeder.
This consistency and the overall environmental impact of the alternative fuel feeding system make it a logical fit for cement manufacturing operations, according to the company.
