Steel is considered the material of choice for protecting surfaces against wear in conveyor systems for heavy materials. In practice, however, steel reaches its limits in many cases. Rico Harting, Product Manager at REMA TIP TOP, has been developing solutions for efficient and sustainable wear protection in conveyor systems for many years. In this interview, he explains which alternative materials should be considered for wear protection and how modern composite systems such as REMALOX HD help to reduce repair and maintenance costs and significantly increase operating runtimes.
Samarco Mineração S.A. has set a monthly production record during August 2023 of 824,829 tonnes of high-grade pellets in a single pelletizing line with its 816 m2 Metso Pelletizing Plant Indurating Machine #4 at its Ubu site in Brazil. At an annual level, the production is equivalent to approximately 8.8 to 9.0 Mtpa of pellets in a single machine. Samarco has installed three additional Metso Pelletizing Plants at its Ubu site.
Rail deliveries of HS2’s tunnel ring segments in London remove a million miles of lorry journeys

HS2’s move to using rail for the delivery of tunnel ring segments to the West Ruislip Portal site in Hillingdon has removed one million miles of lorry movements from Britain’s congested roads.
Since February 2023, HS2’s London tunnels contractor, Skanska Costain Strabag joint venture, has received deliveries of the tunnel ring segments by freight train rather than road – an option which became available once the two Tunnel Boring Machines, named Sushila and Caroline, had been launched and space to access the rail head on site became available.
HS2 Ltd is committed to move materials by rail or waterways where possible, reducing the impact on the UK’s congested road network.
Pacadar UK, based at Thamesport on the Isle of Grain in Kent, is manufacturing the tunnel ring segments for the Northolt Tunnel West, producing 60,000 segments which will form 8,400 rings, for 5miles of twin-bored tunnel. The Pacadar factory is strategically located to enable deliveries to take place by rail freight.
Over 120 trains have now completed the journey between the Isle of Grain and West Ruislip, with an average of 5 trains per week delivering the tunnel ring segments. Each train delivers 144 segments, which when installed underground, makes up over 20 tunnel rings.
Speaking about the materials by rail programme at West Ruislip Portal, Pat Cawley, HS2’s Director for On Network Works, said: “HS2 is committed to responsible construction and using the rail network as much as possible to deliver materials. By using freight routes to deliver tunnel ring segments manufactured by Pacadar to our West Ruislip tunnelling site, thousands of lorry movements will not be required. Our freight programme is a result of extensive collaboration between HS2 Ltd, our contractors, Network Rail and the freight operators and we anticipate that over 20 million tonnes of materials will be moved by rail on Phase One of the HS2 programme.”
400 freight trains are expected to be used to deliver the tunnel segments over the period when the tunnel is being constructed. It is anticipated that this will reduce the carbon impact of the logistics operation by approximately 2,250 tonnes, all part of how HS2 and its contractors, are approaching construction in an environmentally sustainable way.
James Richardson, Managing Director of Skanska Costain Strabag joint venture said: “By using 120 trains instead of lorries to move tunnel segments from Thamesport to our TBMs in West Ruislip, we’ve curbed transport-related emissions by 750 tonnes of CO2 so far, reaching the remarkable milestone of a million avoided lorry miles. This is just the beginning. Overall, across the life of our partnership with Pacadar, we’re projected to reduce our carbon impact by 2,250 tonnes. When construction, manufacturing and rail freight industries work together to maximise transport efficiency, we save money, achieve reduced emissions, cut lorry traffic, and strengthen our industry-wide commitment to achieving a cleaner, greener, low-carbon future.”
HS2 Ltd and its contractors are working closely with Network Rail and the UKs leading freight operators to move materials needed for construction using the rail network. Early in 2024, two further TBMs will begin their journey to complete the Northolt Tunnel – an 8.4mile tunnel being constructed by a quartet of machines. Strabag will be manufacturing the segment rings for the Northolt Tunnel East at a new facility in Hartlepool. From there, the 35,000 segments will also be transported by rail.
