The 45+ tonne Giant (K8), is a very large 6000mm x 2000mm screen, well designed by Keestrack resulting in a high performing, quality unit.

In this version, the conventionally 'difficult to screen' bulk materials are handled with ease by Keestracks' Scalping Screenbox, as they have been for over 20 years.

Not content for the unit to expertly separate these standard, difficult materials, Keestrack has designed this unit so it can also be fitted with the Bivitec Flip Flow Screenbox if required. This is used for products that can block screen openings when scalping, even with the best vibratory screens, such as damp, stalky and leafy materials or matted substances.

With user friendly controls, great access for replacing screens, easy maintenance and proven Keestrack quality you cannot go wrong with this versatile bulk screener. Utilise the Giant (K8) screen as a low maintenance, space saving alternative/solution when screening bulk materials, instead of needing several screens in a train. Get your Giant (K8) today!

The Combi-Flex combines two of the most popular machine features for treating trommel fines, into a compact hook lift chassis design.

It combines Waste Systems patented screening system, which makes small work of materials that were considered too problematic binding up conventional screens, then filters the material into the next stage cyclonic expansion chamber which uses directional cyclonic air streams to give a distinct material density separation of heavy, hard core material and light material that would be used as fuel for biomass etc.

Combi-Flex Features Include:

  • Compact, modular design with hook-lift chassis feature for site movement
  • Versatility – the ability to process multiple waste streams including high moisture content.
  • Extremely efficient product separation using the high energy screen.
  • Fully self contained. 

The Proflow Bio mobile unit is aimed primarily at applications where a high degree of selectivity is required.

The versatile mobile unit is ideal for applications where the desired light fraction is very close in density and weight to the desired clean product such as removing paper and plastic from organic waste or compost.

The unit utilises density separation, air knife blower and suction, conveyor displacement and magnet separation to produce high specification results in one pass.

The Hydro X Tract uses captive water to separate light from heavy materials. The unique separation system used in the unit enables items which are heavier than water, such as rubber and plastics, to be removed with the light fraction. 

Applications for the Hydro X Tract include removing light contamination from recycled aggregates, and removing glass and metal from wood chips or mulch. 


  • Highly effective separation.
  • High capacity, up to 100m³/hr.
  • Low water volume used.
  • Very versatile.
  • Effective silt recovery and removal. 

Designed for screening of multiple material types the Flex X Tract utilises a revolutionary design with a vibrating scalping deck and integrated vibrating flip flow screen to eliminate binding and pegging, available as a stationary unit and on tracks for added versatility. 

The Flex X Tract can screen materials that had once been considered too problematic, or had properties that made conventional style screening systems inefficient and not profitable, with ease. Its unique patented self-cleaning mechanism does away with the need for manual intervention in applications such as C&D, compost, plastic, paper, recycled materials, organics, stone, wood and more. 

Benefits of the Flex X Tract Include:

  • Precision screening of low density, high moisture content, inconsistent feed applications. 
  • Eliminating binding and pegging that prevents efficient screening.
  • Long life screen mats with low maintenance.
  • The ability to screen multiple material types and produce small product fractions (minus 2mm-1/8") when processing difficult materials.
  • Extremely efficient product separation using the high energy screen.


The Max X Tract has the latest in material processing incorporating air and physical separation technologies to remove select material types from primary feed, separating foreign materials from aggregates, biomass fuel, compost, C&D, recycled material and many other primary feed material types.

The results are clean,  high quality products which can be returned to the composting process, used as biomass fuel, meet recycled material specifications, reduce landfill volume and generate new revenue opportunities through effective product selection and separation. 

Benefits of the Max X Tract include:

  • Quality, high value sellable products
  • New revenue stream generation from recovered materials
  • Reduced landfill material
  • More efficient recycling of multiple products

Modelled on a classic three-way split recycling screen, the Proflow DST combines effective flip-flow screening with air density separation. The tracked, diesel/electric driven unit is aimed at a wide variety of mixed waste applications and can be tailored to suit specific materials and product needs.

Proflow screens are made up of two separate decks in one unit that are independently driven, as opposed to the traditional method of having the lower deck suspended on rubber mounts. This method ensures maximum agitation of material and prevents the bottom deck being weighed down, thus preventing blockages and keeping production to a maximum.

This arrangement is highly effective for screening of difficult/sticky/wet material such as skip waste fines, trommel fines, compost aggregate, waste wood processing and more to an infinite variety of sizes. Combined this with the air/density separation and you are assured a consistent and high production separation is achieved. 


  • Touch panel controls.
  • Manual remote greasing on all components.
  • 110m wide heavy duty variable speed feeder conveyor.
  • Unique vibration on each deck created better throw to eliminate screen plugging and blockages.
  • Independent drive Proflow double deck flip flow screen with a screening area of 4.3m x 1.5m on the top and bottom decks.
  • Multiple discharge configurations.
  • Air displacement unit with fully adjustable separation drum.
  • Drum separation contains both heavies stockpile conveyor and lights discharge conveyor.
  • Cyclonic air chamber to allow for better separation of materials in suspension.

The Keestrack Giant (C8)  Bivitec Screen is the most effective screener of 'difficult to screen' bulk materials on the market. It starts where conventional vibratory screens become inefficient and less economical. Difficult products, such as damp, stalky and leafy materials or matted substances block the screen openings of conventional vibratory screens, thus making efficient screening impossible.

The screen provides a simple solution to these challenging demands with the help of resonance: a driving mechanism provides two vibratory movements in which the flexible polyurethane mats are expanded and compressed in turns, and the difficult-to-screen product is separated at high acceleration. The dynamically excited screen mats thus remain free and allow efficient screening. The amount of movement of both oscillating masses can be adjusted, with parameters such as speed, and adjustment of the unbalanced masses, individually adaptable to the screening material.

The Giant (C8) Bivitec Screen is suitable for a wide variety of applications such as fine screening; recycling; compost and peat; screening of difficult, sticky or wet materials to an infinite variety of sizes; aggregates; wood; sand and gravel; iron, steel and metal; concrete; asphalt and more. It can also be used as a low maintenance, space saving alternative/solution, when screening unproblematic bulk materials, where instead of using several screens after another just one Giant can be in place.
