Argentina: Welding Alloys Argentina has manufactured and delivered a key set of wear parts for the classifier section of an FLSmidth OK 36.4 type vertical roller mill installed at an unnamed cement plant. The parts were manufactured at a workshop in San Nicolás near Buenos Aires.

They included a new 5000mm diameter by 2760mm high fine separator section complete with full set of vanes. The section was manufactured in two halves for later assembly on the customer’s site with vanes made from 13 sheets of 6+4 Hardplate 100 and flanges from 16mm 450HB through hardened plate. Also included were the lower cone section manufactured from eight sheets of 8+6 Hardplate 100, the upper cone section from 11 sheets of 10+4 Hardplate 100 and the discharge tube manufactured from 8+5 Hardplate 100, all flanged with 450HB through hardened plate.

UK: Welding Alloys says that it has carried out maintenance on a vertical roller mill at HeidelbergCement subsidiary Hanson’s 1.0Mt/yr Purfleet slag plant in Essex, repairing the mill’s Loesche 46 2+2S grinding table and rollers. The company said that the mill, which had ground 3500t of granulated blast furnace slag (GBFS), was “in urgent need of refurbishment.” Following a wear audit, Welding Alloys took the grinding components back to the profile template using its Integra Wire Mill products.

The group said that “both companies overcame the challenges of completing the project within the limited shutdown period while complying with the Covid-19 lockdown measures.”

US: Welding Alloys has released information about a project to rebuild a FCB Horomill at Buzzi Unicem’s Maryneal cement plant in Texas in early 2018. The engineering company’s Mexican subsidiary Welding Alloys Panamericana has experience of rebuilding these types of mills and it collaborated with the group’s American wing, Welding Alloys USA, on the project.

UK: Welding Alloys has launched MillCarb, a repairable welded ceramic composite alloy providing an engineered wear protection solution for grinding components. It combines the wear resistant properties of advanced and complex ceramics with graded grain sizes and the shock absorbing properties of a metallic matrix, creating a ceramic metal matrix composite. The company says that these features have been incorporated into a weldable solution that is capable of multiplying the life of components by offering a repairable alternative. MillCarb is currently being trialled with industrial partners.
