MORE THAN A MACHINE: DECANTER A centrifuge decanter; consists of a solid cylindirical bowl rotating at high speed, a scroll rotating at the same axis with a slightly different speed, a drive group adjusting the speed difference and the body which carries all the rotating elements. Liquid and suspended solids are fed along the centre line to a distribution room within the bowl and then accelerated into the bowl by centrifugal force through the feeding point. This centrifugal force then causes the suspended solids to settle and accumulate at the bowl wall. Sludge cake is discharged by scroll...

RIGHT ENGINEERING SOLUTIONS Bowl Group The bowl is consisted of two parts: cylindircal and conic Suspension rotates at processing speed along with the bowl and forms a concentric layer at bowl perimeter. Solids available in the suspension accumulate at bowl perimeter with centrifugal force. The length of the cylindrical section of the bowl and the conic section angle are adjusted as per the specific condition of each application. Scroll Group Scroll rotates at a slightly different speed than the bowl and conveys the accumulated solids to the end of the conic section of the bowl. If the...

Material HAUS uses high quality stainless steel on all surfaces that the the product comes in contact with. Wear Protection HAUS decanters offer a wide range of wear protection options to be applied on many areas where they are utilized: Tungsten Carbide coating with plasma spray Ceramic Sintered Tungsten Carbide plates Polyurethane Wear protection parts are in-place replaceable in order to save on maintenance costs of applications where high abrasive products are processed.

Bearing and Lubrication Special selection and order of bearings ensure long machinery life and exceptional reliability. Central lubrication system delivers grease or oil to the bearings. The lubrication system changes depending on the operation mode, e.g. sectional or continuous operation mode and depending on the automation level of the whole system. Leveling Plates Treated liquids flow over the leveling plates and move forward to the end of the cylindrical section of the bowl of which they’ll be delivered to. Easily adjustable sensitive leveling plates enable the pool depth of the bowl to...

DRIVE SYSTEMS HAUS applies advanced engineering techniques to accelerate the decanters to high speeds in safe. One of the most important key factor for decanters is the differential speed. Differential speed determines the amount of moisture hold in the separated solids and the clarity of the centrate. This speed can be adjusted according to the required product characteristics. Drive systems which run to determine this speed are given as below: CENTRIFUGE TECHNOLOGIES

Constant Speed Drive System This system has low investment costs due to very simple design. This drive system is used when the solids amount is constant, the solids can be conveyed easily and the amount of moisture in the solids is not critical, which means it is not necessary to adjust the differential speed. Dual Drive System Dual Drive provides differential speed to be adjusted in a wide range. Second motor drives the gearbox input shaft and makes the differential speed as a function of bowl speed and gearbox rate. Required speed is adjusted when the solids amount is variable noticeably,...

CONTROL AND AUTOMATION Automation of HAUS decanters enables fully automatic operation. In addition to the operating variables of the decanter, below functions can be also monitored from main control room: Bearing and lubrication temperature Bearing and main structure vibration Gear torque or the control of differential speed with respect to torque Leakage control for isolated systems Turbidity control for centrate monitoring Feeding pump flow Chemical make-up unit control Flowmeter Conveyor control

ADVANTAGES OF THE DECANTER Decanter provides the advantage of high efficiency operation compared to traditional separation systems. It was necessary to develop continuing systems in order to reduce the increasing company costs and for the growing industry to be able to adjust itself to the acquired achievements. Operational conditions Application flexibility Decanters provide practically high efficiency results under fluctuations at product inlet, differences in process conditions and even at different characteristics of various products. This capability enables reliable and regular...

Easy installation Corrosion and wear protection It is possible to install the decanter easily and quickly thanks to its design and all the required functions integrated in single unit. Low vibration levels and active support system of HAUS decanters eliminate complex and expensive base construction. Auxiliary equipments and connections are not needed. Process specific materials highly resistant to corrosion and abrasion are used in decanter manufacturing. Personnel safety Closed design of the decanters and the availability of hightech safety systems ensure high safety for the operator and...
