A new type of separators for dressing and separating of different kinds of ores, slag, scratch and other technogene materials has been designed and is being prepared for production.
The separator SXF4-3P-150 can give out three sorting products for one technological operation. It simplifies the technological scheme of primary dressing to a marked degree and reduces expenses on equipment and apparatus chain used in traditional scheme (initial material sorting into two products).

Combined X-ray block of separators (CXB 'BARS') combines two X-ray blocks XB, existing now
