79 ARTICLE MILLER / AUGUST 2019 ing to the wireless network, the Diorit roller mill can be operated by smartphone, tablet or PC within the mill. The touchscreen on the roller mill is optionally available on request because it is no longer needed. Another im- provement is the grinding chamber which has been en- larged by 30 millimeters on the Diorit 2019. That allows the operator more space for product sampling. Reliably monitored State-of-the-art sensor technology in the Diorit ensure that the rolls are always in the optimal position running at optimal speed. It also features integrated roll disengage- ment monitoring. This prevents the rolls from running against each other without product and can generate an error message when needed. Roll speed monitoring on the rear grinding roll checks whether the drive belt is functioning correctly in continuous operation. The op- tionally available, continuous monitoring of the roll and bearing temperature triggers an alarm and immediately stops operation as soon as the rolls or bearing temper- atures get excessively hot. Plus, additional safety fea- tures guarantee the highest level of safety for operating personnel. The Diorit also has a hand guard when fluted rolls are used. This ensures that operating personnel can take product samples during on-going operation with maximum safety. Food safety design The Diorit roller mill also provides high food safety. All surfaces that come in contact with product are made of stainless steel or other food-safe materials. Locka- ble covers secure access to the machine and eliminate the risk of contamination. The swing-out feed module ensures a fast and resi- due-free product discharge while also providing easy access for cleaning. The sturdy, cast-iron Diorit ma- chine frame provides an optimal base for high grinding performance in 24-hour continuous operation. The wide inlet and the variable speed of the feeding roll ensure even feeding across the entire length of the grinding roll, contrib- uting to consistent product quality. The compact, powerful roll pack makes it possible to achieve high accuracy and stable grinding. The wear-resistant, low-maintenance and noiseless belt drive ensures quiet, reliable and continuous operation. The new roller mill Diorit is especially attractive be- cause of its low maintenance. The wear-resistant belt drive ensures long life and reliable continuous operation. The Roll Quick Pack accelerates roll changing which in- creases operating time and contributes to even better overall mill efficiency. Individual solutions possible The roller mill Diorit from Bühler is available as a four- or eight-roller mill in various lengths from 600 mm to 1500 mm. In addition, the four-roller mill is offered with a roll diameter of 300 millimeters for the versions with roll lengths of 1000 and 1250 millimeters. This increases the roll surface by 20%, which extends the service life of the rolls. The grinding surface increases by 10%, which results in higher flour yields in the fine semolina passages and higher fine flour portion and lower starch damage in the smooth roll passages. Differing product inlet and rolls options can be select- ed for all Diorit models. Whatever the requirement for performance and throughput, it can be realized. In ad- dition, the Diorit roller mill has a broad range of optional features for meeting individual requirements, such as di- rect suction and water cooling.
