The Diorit roller mill comes in two designs – the four-roller mill MDDY and the eight-roller mill MDDZ. Both are available in a range of sizes and options. Choose between roller diameters of 250 mm and 300 mm and roller lengths of 600 mm to 1500 mm.

Safety

Additional safety thanks to modern sensor technology

The Diorit is equipped with modern sensor technology. This monitors the rollers to check if they are disengaged and stops them running against each other if there is no product going through the mill. Additional sensors monitor the temperature and speed of the rollers.

We have designed a special swing-out feed module. This helps to easily access the roller mill for cleaning and for emptying out the product.

You can lock the roller mill covers to stop unauthorized access. We have added hand guards to help you take product samples safely.

The split version of the four-roller mill MDDY-600/250 with up to four passages is especially advantageous for mills with smaller grinding capacities.
