Three models on the
The complete programme includes 15 different scalpers and screens; eight tracked crushers, and three stackers.
At Hillhead, the Keestrack C8 track-mounted large-scale screening unit makes its UK debut.
The company says the flexible unit feature a highly efficient double-screen unit with large surfaces (2 x 6,000 x 1,900mm) to be equipped with different screening systems including the specially adapted expansion-shaft BIVITEC Flip-Flow technology of Keestrack’s Austrian development partner Binder + Co.
“This guarantees a very broad area of application in the economic recycling of various waste materials such as glass, wood and slag; the difficult processing of mineral materials with high basic moisture levels, or in the production of large volumes of standard mineral products (up to 1,200tonnes/hour).
“By providing different screening combinations of the double screening unit, it is possible to process, for example, minimum grain sizes of < 2mm efficiently,” says Keestrack.
“If the linings in the upper-deck circular vibratory screen are changed, the unit can also be directly deployed behind a crusher or for the processing of hot materials (slag or substances containing tar).”
The transport weight of the Keestrack C8/K8 unit is 43.5tonnes (HxW during transport: 3.2m x 3.6m) including the 12m³ feed hopper, overband magnet (option) and two side conveyors.
The unit is also said to offer rapid on-site set-up times, and as with several other Keestrack models, the C8/K8 unit is available with diesel-hydraulic and diesel-electric drives (including plug-in option), which is said to substantially lower energy consumption and enable contractors to operate even in most sensitive environments, for example water and protected areas).
Representing the Keestrack tracked crusher range will be the jaw crusher unit Keestrack B4 (Apollo) and the impact crusher R3 (Destroyer 1011). With a maximum feed size of 600mm the 42-tonne B4 jaw crusher offers production rates up to 400tonnes/hour (inlet, 1,100mm x 700mm; CSS, 45-160 mm).
“Efficient and continuous production is guaranteed through a large 5m³ hopper capacity with effective double-deck pre-screening and the patented automatic gap adjustment and safety release system of the crusher,” says Keestrack.
With less than 30tonnes transport weight, including all options such as closed circuit, the R3 is the smallest of Keestrack’s impact crushers, and can produce a maximum of 250tonnes/hour of material in primary and secondary crushing.
The compact unit features pre-screening and the direct driven Keestrack impact crusher with 770mm x 960mm inlet opening.
“The optional single-deck built-on screen unit with recirculation conveyor allows the cost-effective production of specified products with only one machine,” says the company.
