The Contromat VE 450 (photo) and VE 630 (which is square shaped) handle sifting capacities between 0.15 and 0.3 m². Previously, the Contromat had been delivered without an outlet for foreign particles, which remained on the sieve and had to be removed manually or by means of a suction nozzle. Now, the new Contromat version is rectangular, and has an outlet for oversized and foreign particles. It prevents unwanted agglomerates from remaining in the final product. All product-wetted parts are mainly stainless steel (1.4301). Cleaning and replacing the sieve decks is extremely simple, since the Contromat can be dismounted without tools. The control sifter is also available in an optional ATEX version.
