From2992 Keestrack comes the C8 track-mounted large-scale screening unit, which is said to feature an efficient double screen. The large surfaces (2 x 6000 x 1900mm) can be equipped with different screening systems, including the expansion-shaft BIVITEC Flip-Flow technology of its Austrian partner Binder + Co. This allows applications such as processing materials with high moisture levels, or large volumes of standard products. Using different screening combinations allows the processing of small grain sizes while changing the linings in the upper-deck circular vibratory screen allows the unit to be used behind a crusher or for processing hot materials. The machine weighs 43.5tonnes for transport and is said to offer rapid set-up time. As with other Keestrack models the C8/K8 unit is available with diesel-hydraulic and diesel-electric drives. From 2017 the firm will offer diesel-electric drives with plug-in options for its mobile jaw crushers, screeners and impactors as an alternative to the diesel-hydraulic drives.
These drive options are already offered for the H4 tracked cone crusher. It has a new frame design and has a total transport weight of only 46tonnes and a compact transport width of 3m. It also has an intelligent plant control that can be combined with the firm’s GPS-supported remote machine monitoring system.
And6934 Metso says that demand is strong for its novel NW Rapid system, a crushing plant that fits inside standard 12m shipping containers for ease of transport. The wheel-mounted plant can be commissioned in just 12 hours and the firm claims it offers a potential production gain of 30% over rival systems. The increased capacity is said to be achieved by the combination of its Nordberg GP220 cone crusher and its new four-deck dual-slope screen. This is said to deliver high screening performance while the whole plant can be adjusted as required by a process control system. The NW Rapid complies with European safety standards, and it can be issued with a CE marking.
A novel development from the firm is the availability of upgrades for old crusher models intended to reduce maintenance costs and also boost throughput and safety.

Its optional pre-screen unit allows fines to be removed efficiently, maximising production and minimising wear. It also has a new chamber design and optional features such as the hydraulic inlet lid and the automatic adjustment system, as well as auto rotation system for blow bar changes.
5074 Rockster Recycler says that it has developed key innovations for the crushing and screening sector including its patented duplex system, patented double functional return belt and its novel hybrid crusher. Rockster’s R900 impact crusher R900 is a mobile track-mounted machine equipped with a large entry opening and a heavy duty, hard aggregate rotor. It can be used in recycling applications and in areas involving hard or abrasive aggregates. Its hydrostatic drive allows continuous adjustment of the rotor speed to suit operating conditions. The circular motion vibrating screen can be assembled directly on the main discharge conveyor while no separate drive is required to power the screenbox and return belt as they are driven by an additional hydraulic system.
Both the R900 impact crusher and R800 jaw crusher can be equipped with the firm’s novel duplex-system, which allows the crusher units to be exchanged. The machines have an identical drive system so that either the impact or jaw crusher can be installed on the same basic frame. According to325 Sandvik, its new QJ341+ model offers improved efficiency, lower rates of wear and higher productivity. This new jaw crusher also incorporates a double deck pre-screening system, offering high amplitude for efficient separation. This allows for the removal of a large quantity of fines, boosting productivity and reducing crusher wear. The QJ341+ suits applications where a high proportion of fines are found in the feed and the firm claims tests show productivity gains of up to 38% in certain duties.
The unit also features a new telescopic natural fines conveyor, with a discharge height of 3.1m. The dirt chute has been designed with a steeper angle to enable a faster transfer of material and can also handle sticky material. The three-position dirt chute allows all material passing the pre-screen grizzly to be diverted onto either the main conveyor or the natural fines conveyor.
The QJ341+ model also includes a hydraulically adjustable CSS setting, reversible jaw and hydraulic drive, allowing it to start under load as well as featuring the Sandvik PLC control system and control screen. Customers can select also select emissions compliant Caterpillar or Volvo diesels.
