After crushing, the different size fractions are kept separate. By means of Carolina Stalite's unique automatic controlled blending system, requested gradations are developed to meet the most stringent grading requirements for our customers. After blending, actual moisture content is automatically adjusted to a predetermined level. Individual size fractions of crushed material are kept separate in color-coded silos for better gradation control. Automatic blending and moisture control systems allow for the development of consistent and uniform size gradations.
Material is tested for unit weight, specific gravity and moisture content.
Coarse grades are stored in low-elevation stock piles that feature a moisture control system. Ample controlled storage allows the company to supply on-time delivery for any size project. Material can be conveyed directly to trucks or railcars. Fines are stored in low-height, coded silos. Fine material silos are specially designed to minimize segregation.
