Grinds, Screens, Washes, Transports and De-waters

The SPIRALIFT screens, washes, transports and dewaters solids entrained in the wastewater flow. This system combines the benefits of two proven technologies into one effective system: the SPIRALIFT screening/ conveying system and a high-performance TASKMASTER grinder.

Dependable Fine Screening and Washing

Superior Solids Capture

Output Particles Emit Less Odor

Organics Remain in the System

Low Headroom Above Discharge

The processed solids are washed, ground, dewatered and discharged - ideal for landfill disposal, while organics are left in the flow. Because this unit features TASKMASTER grinding technology, it offers the combined benefits of a rugged, effective grinder with enhanced screw screen performance for a uniquely effective and trouble-free system.

HOW IT WORKS

First, a powerful TASKMASTER grinder reduces the solids to small particles, loosens biological material and increases surface area. The reduced solids are ideally conditioned for further processing by the SPIRALIFT screw screen.

As the solids are discharged from the grinder, the reduced particles are subject to the turbulent cleansing action of the channel flow. The particles are then captured on the SPIRALIFT's fine screen basket. The spiral unit is energized on a timed cycle or when the upstream flow reaches a predetermined level.

The brushes of the unit's shaftless screw sweep the solids off the screen. They are then spray washed and transported up the shaftless spiral.

Finally, the solids reach a dewatering zone and are discharged. The cleaned and homogeneous output is deposited in a bin, bag, or auxiliary conveyor.

Taskmaster® Technology

TASKMASTER grinders are an integral part of the SPIRALIFT system. These rugged twin shaft grinders have proven their powerful solids reduction capability and unsurpassed reliability in installations worldwide.

	*HOW IT WORKS!*
Solids are first ground by a powerful Taskmaster and loose organic material separated. As solids are captured on the fine screen a powerful water spray further washes them. The solids are conveyed compacted by the shaftless screw and discharged out of the channel.

S270 Control System

An S270 Automatic Control System monitors and controls system operation. This PLC driven unit is provided standard in a Nema 4X FRP enclosure. System functions include sequence timing, grinder and spiral jam sensing and jogging function, conveyor run timer and level control override, and spray wash solenoid control.

CONSTRUCTION

Franklin Miller's years of experience in building industrial as wastewater solids reduction and conveying systems is the design and construction of heavy duty SPIRALIFT SYSTEMS. The SPIRALIFT screen and trough are constructed of heavy stainless steel. Its shaftless screw is constructed of special micro-alloy steel. The grinder cutters are constructed of hardened 4140 steel and are provided as unique CUTTER CARTRIDGES. The Grinder housing is constructed of ductile iron.

CONFIGURATIONS

The SPIRALIFT system can be supplied either electrically driven or with a common hydraulic drive. Special options include discharge bagger, conveyors, level sensors and heat tracing. Models and sizes are available to meet most installation and capacity requirements. SPIRALIFT can be provided as a stand-alone screw or in conjunction with a TASKMASTER grinder, or as a complete system with enclosure and/or additional solids removal screws.
