INTERNAL CUTAWAY · BOWL & SCROLL

WORKING PRINCIPLE

CONTINUOUS SEPARATION
ACROSS THE FULL BOWL

Feed slurry enters the rotating bowl through a stationary inlet tube and is accelerated by centrifugal force. Solids are driven to the bowl wall and conveyed by the scroll toward the conical discharge end.

Clarified liquid exits over adjustable plate dams at the opposite end. Separation runs continuously across the full bowl length — no batching, no interruption.

UNDER OUR ROOF

Bowls, conveyors and frames are fabricated in-house, assembled, and run against their own control panel before a machine ships.

CONTROL & DRIVES

FULLY AUTONOMOUS OPERATION

Every unit ships fully assembled and factory-tested with an integrated PLC + HMI + VFD control system.

HMI TOUCHSCREEN

PLC CONTROL SYSTEM

SUREFLO HMI TOUCHSCREEN

Live monitoring of RPM, differential speed, G-force, temperature, vibration and torque. Auto cycle and CIP built in as standard.

  • Real-time parameter monitoring across all key variables
  • Dual VFD control on main drive and back-drive
  • Automatic cycle sequencing
  • Clean-in-place (CIP) routine built in

SINGLE DRIVE

Fixed differential speed — constant solids throughput, lower capital cost. Suits stable, well-characterised feeds.

DUAL DRIVE

Variable differential speed, auto-optimised via HMI. Handles fluctuating feed solids without operator intervention.

CONSTRUCTION

MATERIALS & WEAR PROTECTION

Abrasive feed destroys under-specified decanters. Every high-wear zone is protected twice over.

  • Wetted surfaces – high-grade stainless steel throughout; high-strength SS side hubs

  • Feed zone – full-flow design, no blockage or back-pressure

  • 360° solids outlet – maximum discharge area with replaceable hard inserts

  • Frame – mild steel, epoxy paint, vibration isolators

  • Ex options – flame-proof PLC; Zone 1 & Zone 2 purge panels

IN SERVICE

SKID MOUNTED,
BAGGING BELOW

Mounted at height so dewatered cake drops straight into jumbo bags underneath — no intermediate handling; a conveyor can be added on request.

The same arrangement runs alongside our robots when a site needs removal and processing as one contract.
