A. Feed slurry is uniformly distributed over the full width of the filter by a top feed arrangement. This eliminates cake formation problems associated with fast settling material. Gravity helps reduce vacuum energy and cake formation time. Several types of feed box arrangements are available, tailored to the process requirement. B. Cake travels with the filter media which is supported by the rubber drainage belt. Dewatering is accomplished by applying vacuum to the bottom of the drainage belt. C. Differential pressure draws slurry liquor through the filter cloth, along channels in the...

Features & benefits FLSmidth utilizes two designs for the belt-edge seal: 1. Flexible flanges fold down when passing over the pulleys. Both flanges are vulcanized to the edge of the drainage belt. 2. Elastomer lips are raised in the filtration zone and may be supplemented by staticsideboard seals. Belt speeds up to 200 feet per minute. Fast filtration cycles minimize cake thickness for maximum production, and cake washing efficiency and drying. By controlling the speed of the filter and process conditions, cake thickness can be varied from 1/16 of an inch to 8 inches. Low maintenance Heavy...

All phases of design and manufacturing are closely monitored according to strict, documented quality control procedures. Customers are invited to witness the factory test prior to shipment. Because most units are shipped fully assembled, installation costs are minimal. Often, all that is required at the installation site are basic foundation preparation and necessary hookups. Our team can also size and provide all necessary vacuum accessories for a complete turn-key system. Parts & service FLSmidth is dedicated to keeping units functioning at peak performance. Critical replacement items are...

Vacuum pan and lowering mechanism Lowering Mechanism A pan located beneath the support belt drain holes serves as a vacuum manifold and filtrate collection chamber. On larger filters (4600 series and above) a lowering mechanism is provided to simplify vacuum pan inspection and maintenance. On large, severe duty filters, a counterweighted system is required to lower the pan vertically. By maintaining a parallel orientation to the filter surface during travel, this arrangement eliminates realignment difficulties and assures positive reseating. A hinged cable and capstan arrangement and...

Fixed-seal systems incorporate a center rib vulcanized to the drainage belt and a slide strip attached to the vacuum pan. Most of the wear occurs on the slide strip material which can be replaced at regular, predictable intervals, minimizing unscheduled maintenance. Both systems are equipped with liquid lubrication on the slide material, with injection points at regular intervals along the length of the filter. In addition to lubricating the surfaces, the liquid seals against air ingress and cleans the seal surface.
