Frequently Asked Questions:
WHERE DOES INFINITY RECLAIMED CHROMITE SAND COME FROM?
Infinity reclaims chromite sand generated at Amsted Rail’s ASF-Keystone Foundry in Granite City, Illinois. As part of our agreement, Amsted uses about a third of our production allowing us to sell the remainder to foundries outside the Amsted Rail Group.
HOW IS IT RECLAIMED?
Incoming sand is crushed to grain size and screened to remove non sand material. The sand then goes through a thermal reclaimer, three mineral separators and a pneumatic scrubber, producing a clean chromite sand free of organic resins, dust and fines.
WHERE CAN INFINITY RECLAIMED CHROMITE SAND BE USED?
Infinity Reclaimed Chromite Sand can be used anywhere in the foundry where new chromite sand is used. Since there are no residual binders on the sand it can be used with any of the commercially available core and mold binder systems.
WHAT TYPE OF CORE STRENGHTH ARE ACHIEVED USING INFINITY RECLAIMED CHROMITE SAND?
In laboratory testing, Infinity Reclaimed Chromite achieves 90 to 120 percent of the tensile strength achieved with 100% new chromite sand.
WHAT TYPE OF CASTING RESULTS ARE ACHIEVED USING INFINITY RECLAIMED CHROMITE?
Most customer applications using Infinity Reclaimed Chromite consist of cores and molds made with varying percentages of silica sand and chromite sand. No difference can be detected between Infinity Chromite and new chromite sand.
HOW MUCH CAN BE SAVED USING INFINITY RECLAIMED CHROMITE?
Infinity Chromite Sand can save foundries 20 percent or more over the cost of new chromite sand.
