Preheater
Preheater

We are the world market leader in the field of preheaters

A preheater with a throughput of 51 tph leaves our production facility and is sent on its journey to the customer.
KÖLLEMANN preheaters are used to heat up petroleum coke. Petroleum coke is a residue formed as a by-product of petroleum refining and is made of almost pure carbon. KÖLLEMANN preheaters perform the heating process and heat the product from at least 0°C to approx. 200°C. The heated petroleum coke is then mixed with hot pitch in a kneader. The paste formed is then pressed into a block shape. These blocks are then baked and represent the anode, which is used in the Hall-Héroult process (electrolysis) for the reduction of aluminium.
