Spirale - Import export

Application The internal transport of residuals and recyclable fractions, e.g. sievings, screenings and material from grit chambers in waste water treatment plants, as well as various media within production processes, is effected for many years now by belt, spiral and screw conveyors. These systems have proven as very reliable and versatile. As a “connecting element” the PWL GmbH & Co. Anlagentechnik KG supplies the optimal suitable conveyor technology for your specific application. We recommend the encapsulated design of spiral conveyors for process and waste water technology. The spiral conveyors impress with their compact design, the robustness towards clogging and the option to be equipped as a spiral press for simultaneaous dewatering of the conveyed material.

Application Dewatering and compacting of sieving residues play an important role in water, waste water and waste treatment not only regarding reduction of costs for disposal and handling. Frequently, residues and recyclable fractions are dewatered and further compacted within production inherent processes. Furthermore, dewatering systems have the additional effect to transport the material from the source of origin to the place of disposal. PWL screw presses and PWL spiral presses meet these challenges to all intents and purposes and allow for an optimal benefit at a small footprint. The way of dewatering and conveying as well as the characteristics of the medium determine to a great extend the choice of the suitable equipment. Compared to the shaftless spirals which reliably convey large and long-fibrous pieces and are robust towards clogging, screw presses achieve higher dewatering results with the same size. Function The material to be dewatered passes a hopper or an upstream...

Application The PWL Spiral Sieve HXS presents among the fine screens one of the most efficient solutions for small and medium waste water treatment plants and for some industrial branches. Functional Description In one screening system with one drive only the PWL Spiral Sieve HXS offers three functions. Besides sieving and separation of solids from waste and process water the screenings are conveyed and dewatered at the same time from the screening area for further direct discharge into a container or into a downstream conveyor unit, for example into a PWL Spiral Conveyor. Equipped with either a perforated screening surfaces or wedge wire sieve baskets and installed into tank or channel this Spiral Sieve offers a broad field of applications. The swivelling out mechanism and the transport area which is designed as a conveyor trough with removable covers of the PWL Spiral Sieve provide for easiest maintenance. Your Benefit sieving, transportation, dewatering in one system high...
