Centrifuges

Surface Finish

Mirror or Matt Finish can be provided with Grit 220 & Above on Contact & Non-Contact areas.

Drive

A.C. Inverter Drive shall be provided to vary the basket speed with built-in dynamic braking.

Cleaning-In-Place (C.I.P.) Arrangement

Provided in the centrifuge machine to clean the internals of the filtering centrifuge machine. CIP nozzles are placed at a different location to spray the wash liquid to all the surface which are not accessible from outside. During the cleaning process the centrifuge basket to be operated at a low speed to make cleaning more effective.

The 4-point Suspension

The centrifuge is mounted on inertia platform and suspended over four vibration-isolating dampers. This provides the following unique advantages:

• No foundation required
• Modular Design with Complete Flexibility to relocate the filtering centrifuge anywhere in the plant.
• Drive system (Belt & Pulleys) totally enclosed and can be purged with Nitrogen gas (Flameproof Design).

Zero Speed Interlock

The pneumatic cylinder will automatically get engaged with the lid as soon as basket starts rotating and gets disengaged only when it completely stops which will ensure that the lid can be opened only when the basket comes to a complete halt.

Proximity Sensor

Shall be provided as a safety interlock for the Lid / Body. Unless the Lid / Body is closed motor cannot start and once the lid is opened motor power cuts off.

Vibration Tripper

Will trip the Centrifuge during excessive vibration.

Vibration Monitoring System

This system shall continuously monitor the vibration level of the machine. The system has two set point, one set point is for Alarm level and another set point is for trim level. The system also gives 4-20 amps output which can be hooked up to PLC.

Nitrogen Blanketing System/ Nitrogen Inertisation System

The Nitrogen Inertisation is provided to the centrifuge basket chamber (casing) and to the bearing housing (sealing system). This system shall ensure that during the centrifuge operation the adequate nitrogen pressure is maintained within the basket chamber and bearing housing stuffing box chamber. Therefore, creating a Flame Proof System.

• Note: Oxygen Analyzer can be provided in the vent line.

Automation

Programmable Logic Controller

All the process cycles of centrifuge operations can be automated through a Programmable Logic Controller. The instruments mounted on the machine will communicate with the PLC system. The process cycles can be specifically designed and programmed to work according to the logic.

• Note: Intrinsically Safe Graphical control display (H.M.I) can be provided.

Heel Blowback System

The centrifuge machine is fitted with residual cake heel blowback system, which will remove the residual cake heel after the scraping operation.

Motorised Conical Feeder

It comprises concentric cones fabricated out of SS-316 sheet driven by 1 H.P. motor with frequency drive. This system facilitates uniform distribution of cake throughout the basket. Washing of the cake can also be performed through the same cone. The design also facilitates speedy extraction of mother liquor and wash liquid as well.
