Classification system separates at dual cut points
A clever upgrade from classifiers limited to a single cut point, the Dual Classification System (photo) enables processors to separate feed materials into three different product streams instead of just two product streams to meet gradation specifications for multiple products and help convert material discarded as waste into saleable product. Devised for classifying cement, limestone, asphalt sand, filter sand and other aggregates, the Dual Classification System integrates the company’s Gravitational-Inertial Classifier (GIC) with its Centrifugal Classifier (CC) to separate the feed material at any cut point from 300 μm to 63 μm (50 to 230 mesh) during the initial pass, then at any cut point between 100 μm to 15 μm (950 to 150 mesh), all with a uniform distribution. The Dual Classification System is custom-designed and manufactured for each installation to meet target production goals and material specifications. The system is proven to perform continuously in unattended, continuous operation. — Van Tongeren America, LLC, Lebanon, Pa.
