1 INDUSTRIAL DIVISION CENTRIFUGAL EXTRACTORS for industrial use

2 CENTRIFUGAL EXTRACTORS A LEADER IN CENTRIFUGATION With its vast number and range of installations Pieralisi is able to offer the full spectrum of centrifugation solutions available to meet production requirements and offer new solutions to industrial processes. More than 38,000 Pieralisi centrifugation systems have been installed all over the world in a wide variety of industrial fields. Centrifugal extractors (decanters), vertical centrifuges (separators), belt filter presses and filter centrifuges Pieralisi technology is available to solve any problem of clarifying, dewatering and separating with the safety and reliability derived from a progressive, innovative production. being made to find new solutions to the many problems that arise, taking new approaches and anticipating future developments. The aim of such activity is to generate new products, improve quality levels and reduce costs. Pieralisi's constant coitment to research is aimed at finding and developing new fields for the use of centrifuges, carrying out the necessary tests and monitoring the effectiveness of these new applications. The results have received wide recognition not only from the market, but also from top research institutes. RESEARCH - THE KEY TO GROWTH Pieralisi's business strategy is based on the constant coitment to research. Innovation is one of the foundation stones on which the group's strength lies. The group's dedication to this aspect is demonstrated by the efforts continually

3 A L E A I N C E N T R PRINCIPLES OF THE SEPARATION SYSTEM The decanter is used for the separation of two or more phases of different specific gravity, in particular for the clarifying of liquids in which suspended solids are present. The separation of solids and liquids takes place within a cylindrical/conical rotating drum, upon the periphery of which the heavier solid phase collects and is continually removed by the internal conveyor. A polyelectrolyte, suitably chosen for its type and specific characteristics, may be added to the product being fed to the machine in order to improve the solid-liquid separation. The polyelectrolyte favours the aggregation and thus the easier capture of the solid particles. A polyelectrolyte is not always compatible with products being processed. It is generally used in purification processes for the drying of sludge, but not in intermediate product conversion processes, and even less in the processing of foodstuffs. The ROTOVARIATOR - an electronically prograable electro-mechanical system - is designed and manufactured by the Pieralisi Group and patented worldwide for application on decanter centrifuges of the FP 600 and JUMBO series including already installed decanters. The ROTOVARIATOR continuously varies the number of screw revolutions in relation to the bowl of the centrifugal extractor. Thanks to the Rotovariator device, it is possible to: regulate the torque on the decanter reduction gear to the maximum levels allowed; obtain the highest possible percentage of dry solids in dewatered sludge according to the type of product; ensure the highest levels of sludge capture; adjust the rate of feed flow to the decanter thanks to a frequency inverter on the feed pump.
