erex|Finlay showed off the latest addition to their 8-Series lineup of heavy-duty screeners, the 883+ triple-shaft, at bauma 2019. This new model has been developed specifically to work in a variety of dry and difficult sticky applications including quarry, mining, sand and gravel, construction and demolition debris and recycling applications. The heart of this new model is the new triple-shaft screenbox, featuring two true full-size 16- by 5-foot screening decks. The triple-shaft design of this new screenbox employs an oval motion stroke to generate an aggressive screening action, reducing plugging and blinding over the screen decks to ultimately provide a quality product with high tonnage output.

The aggressive screening action of the machine with its larger throw on the screenbox makes it ideal for fine screening a diverse range of materials. Even when under heavy load during the testing phase the screenbox has consistently produced high tonnages across a range of difficult and challenging applications. Terex|Finlay retained some of the in-built features of the current 883+ screener, including the ability to hydraulically raise the discharge end 500 mm to facilitate easy and efficient media changing. There are three new design features included in this plant: first, the width of the fines conveyor has been increased to 900-mm wide. Second, hydraulic power to the fines conveyor has been increased; and third, the engine has been set to run at a lower speed. Each of these features have been incorporated to maximize the overall operational ef-

ficiency of the plant. Those updates will be carried across into the standard 883+ platform and will be a feature on plants configured with either the standard screenbox or Spaleck screenbox option. Key features of the 883+ triple-shaft: • Higher G-force and larger stroke of the triple shaft screenbox provides the optimal solution for high productivity in dry and sticky applications; • Multiple media configurations including bofor bars, finger screens, woven mesh and punch plates are available for a wide range of applications, from fine screening to heavy scalping; • All media configurations are compatible with both the standard and triple-shaft screenboxes; • The banana profile of the bottom deck maximizes the screening of fine materials.

gle-source crushing, an RM first: the screen can be powered through the new RM 120GO! NEXT hybrid crusher. Both crusher and screen can operate from a single power source. The crusher’s high-power generator supplies the electricity without the need for an additional diesel engine. This reduces emissions and noise levels. The customer has more mobility and flexibility than ever before when using the equipment because, apart from the single source crushing, the hybrid screen can also be operated by a diesel engine or other external power sources. But RM has gone even further: The screen and crusher communicate with each other without wires or cables. When the crusher’s discharge belts are started, the screen also starts automatically. If blockages or faults occur, the screen also stops automatically. In addition, on the RM MSC8500e, a full-featured radio

remote control system with display is used for the first time.   RM GO! NEXT is the logical continuation of the RM GO! principle. Notable features are even more intuitive machine operation and further improvements to access points for maintenance and repair work. RM GO! SMART has been using an app to make customers’ lives easier for several years now. A new feature








RM GO! NEXT takes development of the Rubble Master GO! line to the next level. This makes RM crushers and screens even safer and incorporates numerous digital features on both crushers and screens as well as a fully integrated hybrid drive and an RM innovation. Crusher and screen are coordinated using a central control unit, optimizing overall performance. Rubble Master and Maximus have been working on an innovation in the screens sector: the new fully electrified RM MSC8500e hybrid screen. The new screen was developed on the basis of the tried-and-tested RM MSC8500M screen unit. All the hydraulic drives have been replaced with electric ones. Only the crawler gear remains hydraulic. Components have been integrated that were developed specifically for RM in order to create powerful and robust hybrid machines. All these engineering innovations add up to sin-


that resulted from the development of the hybrid screen is that every fraction can be weighed individually by means of integrated belt scales. Up to four weighing points are possible and provide real-time data via the app. The RM Partscout offers a glimpse of the future of spare parts management. With this new RM app, it will be possible in the future to scan the required spare part with a cameraphone.
