Screw feeder PreMix

PreMix combines four steps within a compact, space-saving unit. The universal feeder system is a combination of our progressive cavity pump (CC series) with the RotaCut RCX cutter. Optionally the solid matter feeder can be equipped with the Debris Removal System (DRS) and Debris Lift Unit (DLU). The biomass is introduced into the side of the system through any feed screw. At the same time, liquid (recirculated material, liquid manure) is added. In a single step, the PreMix turns this into a homogeneous organic suspension and pumps it into the digester. As the biomass is mashed into a homogeneous suspension which can be pumped, multiple digesters can be fed via a pipe network with one PreMix, and additional containers can easily be connected at a later time. Contrary to many comparable feeder systems, the PreMix separates out heavy material from the input while still upstream of the integrated pump unit, which the Debris Removal System then removes during ongoing operation. The PreMix mixes solid and pasty input materials with liquid into a homogeneous suspension. At the same time, coarse particles and fibrous matter are cutted. This means that a well-prepared suspension, free of coarse disruptive matter and foreign matter flows into the pump. This protects the pumping parts and significantly increases the service life of the pump unit. During the development of the PreMix solid matter feeder, attention was paid to ease of service and maintenance. All necessary work including the replacement of parts subject to wear can be done quickly and easily on site. This keeps interruptions to operation to a minimum.
