New innovations to flip-flow screen

The unique stepped top deck design combines with state of the art Flip-Flow Screen Elastica technology on the bottom deck.

The Spaleck?s processing capabilities and application flexibility make it the only all-in-one mobile solution for the processing and separation of most aggregate or materials that stick together due to moisture and dampness, eg recycling materials such as incineration slag, shredder light and heavy fraction, scrap metal, electronic scrap, C&D, C&I, bulky waste, compost, plastic fractions, biomass and topsoil.

The special screen features include:
?    Nearly blockage-free screening in the upper and lower deck thanks to tried and tested 3D and flip-flow technology.
?    3D screening segments that guarantee accurate screening with no long pieces passing into the middle grade material.
?    A flip-flow screen with screwless-mounted screen mats, which avoid unnecessary cleaning and reduce maintenance times.
?    A screenbox discharge end that can be hydraulically raised 500mm to facilitate efficient and easy media access and changing.

The standard screen features include:
?    A tier 3/stage 3A Caterpillar C4.4 ATAAC four-cylinder diesel engine developing 83kW (111.3hp) at 2200 rpm.
?    An abrasion-resistant plate steel pan apron feeder with heavy duty chain drive.
?    Hopper capacity of 7m? (9.16yd?).
?    No grid unit.
?    Screen media fitted as standard.
?    A hydraulic raise for mesh changing (500mm).
?    A 4800mm x 1500mm (16? x 5?) 3D punch plate top deck.
?    A 3650mm x 1500mm (12? x 5?) flip-flow technology bottom deck.
?    A galvanised catwalk around the screen, complete with handrail, kick board and access ladder.
?    A screenbox reject chute.
?    A 1200mm (48?) wide oversize conveyor with twin drive and chevron belt (3.6m discharge height).
?    An 800mm (32?) wide chevron belt on a middle grade conveyor with variable speed and thumper roller.
?    An 800mm (32?) wide plain belt on fines conveyor with variable speed and belt scraper.
?    A remote start/stop of the pan feeder.
?    Skirting on the oversize conveyor.
?    A heavy duty undercarriage unit with 400mm wide pads and 3280mm sprocket centres.
?    Controlled operation of the tracks via a handheld set with a 5m connection lead.
?    Low level greasing.
?    Emergency stops (4nr).

In the centre of the mobile plant is the 3D Combi Flip-Flow Screen. This combined model guarantees that the product is optimally loosened and turned over on the upper deck. Even large-grained material can be screened on this unit with a flip-flow screen deck.
The screening deck with 3D screen segments, which is positioned above the flip-flow screen deck to form a cascade, protects and reduces the stress on the flip-flow screen mats. Their service life is increased and optimal screening results are assured.

The 3D screen segments, featuring maximum open screen area, can be changed quickly and simply, thanks to a modular construction. The screen mats of the flip-flow screen are fastened without screws and have no edges that could cause difficulties. This means the screen mats can be changed quickly and there is an optimal product flow on the screen mats.

The Terex Finlay 883 Spaleck, along with the complete Terex Finlay screening and crushing range, is available in Western Australia and the Northern Territory exclusively from OPS Screening and Crushing Equipment Pty Ltd. OPS has been providing a professional equipment sales, hire, parts, service, plant design and consultation solution to the mining, screening, crushing, washing, block-making, construction and earthmoving industry sectors since 1989. ?
