Twin-shaft batch mixer – the benchmark for mixing technology

Due to its design, the twin-shaft batch mixer of type DKXK is less prone to wear and tear than conventional mixing systems. Its rubber trough makes the DKXK ideally suitable for operation as a main mixer for highly abrasive sand-lime blocks. Twin-shaft batch mixers of the DKXK series are available with capacities ranging from 1,000 to 6,500 liters.
