The cooled, expanded slate is conveyed to the classification area. There it is crushed and screened into different size fractions. After crushing, the different size fractions are stored in separate silos until they are blended into standard or custom gradation blends.
Carolina Stalite’s automatic controlled blending system accurately produces blends to meet the most stringent grading requirements for our customers.
The moisture content is adjusted to a predetermined level. We then test the aggregate for moisture content, specific gravity, unit weight and grading prior to shipment.
High quality, high performance structural lightweight concrete is essential in today’s high technology construction. Here are examples of Stalite’s 3/4", 1/2", 3/8” gradations.
