Break Machinery Srl has significantly expanded throughputs on its Duo line of filters with two new models, the 7000 DS Twin and 5600 DS Twin. Both have two Duo screen changers running in parallel.
Italian manufacturer Break’s equipment became available in North America in 2022 when ADG Solutions became the exclusive distributor.
The 7000 DS Twin has a filtering surface area of 1,090 square inches and maximum flow rate of about 26,500 pounds, while the 5600 DS Twin has an 883-square-inch filtering surface and maximum rate of about 22,000 pounds per hour.
Both new units have 14 heating zones. Maximum line pressure is about 5,000 pounds per square inch.
To increase the filtering area and production volume, all sizes of Duo filters have two perforated discs. A scraper disc between the two filters has blades on both sides and rotates to remove contamination from both surfaces.
The geometry prevents filtered contaminants from re-entering the melt, according to the company. The filter surfaces are constantly cleaned so they can be used for longer periods than conventional systems.
With two Duo screen changers running in parallel on the 7000 and 5600 models, a screen change in one of the units can be accomplished by cutting off the flow to one unit while production continues with the second unit.
Using two filters means the size of the filtration chamber can be reduced.
The six-blade scraper disc cleans even at low rotation speeds. Impurities are discharged with a single screw capable of conveying them from both filter surfaces.
The company said that adjustability of the speed of the discharge screw allows heavily contaminated materials to be processed, while maintenance operations and replacement of filters and blades can be accomplished without dismantling the machine.
The new DS Twin machines join five other Duo models, which have a maximum flow rate of around 13,200 pounds per hour.
