The new Dispermat SL-B horizontal bean mill (photo, p. 30) is suitable for fine grinding batch sizes from 150 to 750 mL, and features an integrated mill-base circulation system, which means there are no external pumps to clean. The speed control is infinitely adjustable from 0 to 6,000 rpm. This new model utilizes an integrated pneumatic press-out system, whereby the mill base is pressed out to ensure that the dispersed product can be almost completely regained with minimal wastage. The product sample is conveyed through the horizontal milling chamber with minimal clearance volume by a spiral conveyor, which is connected to the milling rotor, while the separation of the mill base is made by a dynamic gap. The mill features a wear-resistant stainless-steel milling chamber and a milling rotor made of hardened nitride steel. Shaft sealing is provided by a mechanical seal with integrated pressure system and cooling. An explosion-proof, ATEX-approved version is also available. — Fullbrook Systems Ltd., Hemel Hempstead, U.K.
