Metso’s range of screeners from the FS Series range provides an effective solution to an overlooked part of the quarry.
Efficient and cost-effective screening of aggregates is often the forgotten part of many quarry operations. Many times, the focus is on the reduction of material when considering the production of products for sale. Unless the crushed rock can be correctly sorted at a high and efficient rate there is no value to be had in the sales yard. Metso understands that a quarry is a holistic process from material selection, blasting, crushing screening and storage of finished products. As a result, it has always considered how the materials are sorted and either presented to the next crushing stage or sent to the final product.
This is where highly efficient vibration technology comes into play, which is why Metso is introducing the FS Series range of low-profile horizontal screens to the Australian market. The FS Series low-profile horizontal screens are part of the wider range of Metso vibrating technology offerings, which includes the inclined CVB Series, multi-slope TS Series and self-synchronising horizontal ES Series.
More importantly, the FS Series offers improved design, efficiency, and ease of maintenance of Nordberg MV modular mechanisms. Designed as a grease-filled, easy-to-change-out bearing and vibration unit, Metso has eliminated the messy and costly oil gearboxes of decades past.
Designed for Safety
Metso’s number one priority is personnel health and well-being. Eliminating risk is the best solution to preventing injury, which is the key factor in the design of all Metso equipment. The FS Series is no different.
Risk reduction through safer operation and maintenance is now possible with the MV mechanism, being a one-piece modular construction that reduces risk without the multiple-parts replacement and repairs.
Further, the mechanism end cap is lightweight aluminium design, removable by hand for easy maintenance tasks and functional design changes.
Designed for Life
Aggregate separation involves high forces and stresses. To ensure the longevity of assets, care must be taken during the design, manufacture and operation of vibration equipment.
Screens not only have to be rugged enough to function and last in the harsh quarry environment but handle long term stresses. The FS Screen is designed with Finite Element Analysis, which ensures a balance between strength and performance. Each FS Screen is factory tested to ensure the highest quality and customer-specific vibrating characteristics.
The FS Series is a weld-free side plate screen using huck bolt construction, with bolted reinforcement plates and stiffeners. Removal of welds is key to a long life, given the high G-forces and the material load required to be transported along the decks in a manner to maximise separation; huck bolting provides such durability.
To provide the throw and forces needed for separation, the Metso FS design combines the revolutionary feature of the Modular Vibrator (MV) with an extra heavy screen body. MV Mechanism true cartridge vibrator system design that drastically increases uptime.
Four bearings per shaft line provide a longer bearing life, allowing for larger load capacities while lowering operating costs. The bearings are in the centreline of the side plate for equal loading and reliability.
Individual bearing systems eliminate lubrication cross-contamination. No refill or draining is required; only a simple low-frequency greasing schedule is needed.
Designed for Flexibility
High G-force and liner motion design ensure the low-profile horizontal FS Series are the best separation solution both as a scalping unit or finishing screen. The primary two-deck model has heavy-duty deck frames for the most arduous applications and can be fitted with top-deck punch plates as required. All models come with one of the easiest stroke adjustments in the industry via the MV Mechanisms. The lightweight aluminium end cap is easily removed by hand for a quick stroke adjustment, for to fit any application.
The low-profile design of the FS Series is an important consideration in today’s world where providing value is critical. With a low installation height savings are made in the design of new stations on conveyor length and overlay plant height. Access to the top deck is also easier and safer as is brownfields replacement of other less efficient and costly horizontal screens. The FS Series replicates the same envelope and footprint as the older style units, making upgrading a simple task.
Metso and its Australian distribution and service partners can offer a safer, more efficient, and cost-effective solution with the FS Series vibrating screens. •
