The velocity of material vertically entering the chute was estimated at 15 to 34 m/s depending on the fill height of the silo. A three-stage approach was taken. First the existing situation with the highest velocity was modelled with DEM (Discrete Element Simulations), and the results of the wear profile on the existing chute were compared with practice. Secondly, three configurations were designed and the performance of these configurations in terms of wear volume were tested by simulation. Thirdly, and lastly, the performance of the configuration in terms of ensuring material flow through the chutes for a cohesive coal was evaluated. Based on the results of the simulation, two chute designs showed an improved performance where less wear was observed while securing flow through the chute.

Heidenheim, Germany – BeltGenius ALEX (Alignment Expert) from Voith analyzes the alignment of carrying idlers in conveyor systems as part of its service portfolio. As soon as the system sensors detect a deviation from the set values during their temporary measurement, BeltGenius ALEX reports the problem and provides specific solution suggestions. In first installations, the system greatly reduced idler wear, energy costs, and associated CO2 emissions. Continue reading Voith: Optimized Belt Alignment reduces Energy Consumption and Idler Wear
Kuchl, Austria – The new X-Cutter (XC) system for the UNTHA XR waste shredder, designed to achieve the next generation of performance for single-step SRF shredding or provide a direct replacement for existing high-speed shredders, can transform varied input wastes ranging from waste wood through to pulper ropes. Continue reading UNTHA: New Cutter System for XR Waste Shredder offer low Wear and high Efficiency
Rheinberg, Germany – Industry has many choices today for conveyor chains. Most available chains are designed for a certain strength rating and expected wear life. However, there is much more to chain design than these basic parameters. AUMUND, being a conveyor specialist, has designed their chains to meet the demand of certain heavy production industries, based upon more than 40 years of experience.
Helsinki, Finland – Metso is investing in the development of its foundry capacity in Vadodara, India. The initial investment includes the acquisition of the property and foundry assets of a privately-owned foundry project, Mega Cast. Metso expects to invest a total of approx. EUR 25 million to purchase the assets and to develop the foundry by 2020.
Bolton, United Kingdom – The design the Ajax Equipment LynflowTM Chute arose from a demanding duty requested by a user, who wanted to monitor the rate of discharge down a chute from an Ajax continuous mixer. The task was difficult because the product had poor flow properties, the very small rate of discharge from the mixer fluctuated and was spread over a relatively wide path, whereas the monitoring device required a steady bed thickness of at least 10 mm deep.
