This listing features an Alfa Laval decanter centrifuge, model AVNX935B-31G, manufactured in 1993. The machine is designed for dewatering active biological sludge and has a bowl diameter of 450 mm. It operates at a maximum speed of 3250 rpm and has an output capacity of approximately 20,000 liters per hour. The decanter is powered by a 45 kW motor and includes a Viscotherm Rotodiff gearbox.
The system includes a Rotodiff 1070 D automatic back drive with a hydraulic station driven by a 22 kW motor, capable of delivering a continuous torque of 7433 Nm at 250 bar pressure. The bowl features a steep cone with a baffle disc on the conveyor cone to enhance the dry solids content in the dewatered sludge. The maximum sludge density handled is 1.2 kg/dm³, and the system has a pitch of 140 mm.
The equipment comes mounted on a metal frame and includes an Alfa Laval original electrical panel equipped with Omron frequency converters. These converters control the decanter motor, polymer stirrer, polymer screw, polymer pump unit, and sludge feed pump. Technical documentation is included.
The machine is presented in blue and shows signs of surface wear consistent with use but appears structurally intact. Visible components include the electric motor mounted on the right side and associated piping and valves for fluid handling. The polymer unit compatible with this system is available separately.
Please note that the description does not include information on the machine's current operational condition or any refurbishment status beyond the provided data.
The following description has been generated using artificial intelligence based on the product information available. It is provided for guidance only and may not reflect all specifications or conditions. Please contact us if you need precise or confirmed details.
Reconditioned Alfa Laval decanter, type AVNX 935B-31G with Viscotherm Rotodiff gearbox. Complete, including machine frame, 45 kW ABB motor, 50 Hz, 380 V.
Vicotherm Rotodiff automatic back drive system with hydraulic station with 22 kW motor. The Rotodiff 1070 D has a continuous torque of 7433 Nm at 250 bar pressure.
For dewatering of active biological sludge. Capacity: approximately 800 kg/hour. I ex. 20 m3/hour with 4 % dry solids.
Drum diameter: 450/258 mm, Max sludge density: 1,2 kg/dm3, max bowl speed: 3250 rpm. Pitch: 140 mm.
The bowl has steep cone with baffle disc on the conveyor cone in order to achieve higher dry solids content in the dewatered sludge.
Including Alfa Laval original electrical panel with Omron frequency converters for decanter motor, polymere stirrer, polymere screw, polymer pump unit and sludge feed pump. Including technical documentation.
We have the polymere unit available for this system.
