Rotary Kilns - Processing Equipment for the Heat Treatment of Bulk Solids

摘要

Rotary kilns are frequently used for the thermal treatment of bulk solids used in daily life. Their applications extend from chemical and pharmaceutical products, such as pills and pigments, building materials, such as cement, mining and smelting materials, such as ores, coal and coke, to catalyst substrates, abrasives and battery materials. In each case the heat treatment process must be adapted to the respective type of bulk solids. Today, in addition to a wide range of different industrial furnaces, principally rotary kilns are used [1-3].
