  • Refratechnik - Rotary kilns

    Concepts for rotary kilns. Task. Slightly angled downwards, the kilnʻs rotation transports the precalcined raw meal from the inlet to the discharge end (kiln hood), whereby the temperature increases along the kilnʻs length. Hereby, the required clinker phases are created at material temperatures up to 1450 C. Demands
