Plant and equipment for the dewatering of sludge from wastewater and industrial process centrifugal extractor. New Decanter with openable cover structure • Dewatering of sludge • Used and renery oil recovery and extraction • Liquid treatments • Sludge treatment from food industries process Ecology / Depuration Industrial Chemical / Petrolchemical Food Industry Zoo-technical Main Materials Used AISI 304 / 316L* / DUPLEX* AISI 304 / 316L* / DUPLEX* Dehydrated solid discharge Slots with interchangeable guards Screw wear protection Spiral (continuous coating) Tungsten carbide Internal diameter of the bowl Total lenght of the bowl Slenderness ratio Internal capacity Differential speed of the screw (standard version) Hydraulic Version H Main motor power Hydraulic Version H Main motor starting Power of the solids scraper motor Size and Mass Dimensions 5.350 Static Mass Mean noise pressure level (empty - free space) Feeding Pipe Solid and liquid chamber discharge External case Carb. steel / AISI 304* / 316L* / DUPLEX* Support structure Carbon Steel * upon request High Quality Materials All parts of the centrifuge in contact with the product are made of Stainless Steel AISI 304 or 316L, except for the drum which is made of Duplex Stainless Steel to ensure mechanical resistance to abrasion and a strong chemical corrosion resistance. The components of the centrifuge most exposed to the erosive action of the normal biological sludge are protected with a thick coating made of high Tungsten Carbide. The exit holes of the dehydrated sludge are protected with ceramic material which has a very high surface hardness to provide a much higher durability of the centrifuge. Dynamic Mass Ring adjustment of the liquid level inside the bowl Technical Specification Standard and Optional Hydraulic flow-rate (water without solid content) Hydraulic Version H via Mutilati del Lavoro, 105 63100, Ascoli Piceno, Italy The centrifuge can be equipped with the automatic and continuous adjustment device of the differential speed of the internal screw which adapts the operation of the centrifuge to the actual immediate feeding conditions, in order to obtain maximum efficiency and the minimum consumption of polyelectrolyte and energy, compatible with the instantaneous load input. The hydraulic system delivers high torque regardless of the required speed of rotation and brings our system to be one of the most performing today available on the market in obtaining high concentrations of SS on the dehydrated.
