Mechel PAO, one of the leading Russian mining and metals companies, reported that a sweeping campaign of major repairs is being implemented at its mining division’s washing plants. The total cost is more than RUB1 billion ($13 million).
“Upgrade of our washing facilities is a key condition for increasing production,” Mechel Mining Management OOO CEO Igor Khafizov said.
The largest upgrade was completed at the Neryungrinskaya prep plant in September, which included replacing and restoring trunk conveyors, as well as conveyors at the finished product loading area. Yakutugol’s specialists and contractors assembled three new sizing screens and overhauled nine more. The plant also launched three new centrifuges for dewatering clean coal. The plant’s sludge pumps are being renewed. Five new magnetic roughers are due to be acquired before the end of the year. The plant also plans to repair two drying machines, one of which has been finished in September and the second is due to launch in October.
The Krasnogorskaya prep plant acquired seven new vibrating and high-frequency screens, 14 pumps and one magnetic rougher. Two magnetic roughers and five belt conveyors underwent major overhauls. By the end of 2020, the plant plans to replace two vibrating centrifuges, three screens and other equipment.
The Sibir prep plant installed several new machines, including a vibrating centrifuge and a pumping system.
The Kuzbasskaya prep plant replaced two rotors of a screen bowl centrifuge and a separator’s basket wheel. A large-scale campaign of replacing conveyor belts on the plant’s major routes is currently under way. By the end of the year, the plant intends to upgrade its pumping equipment and repair the jig washer.
The Tomusinskaya prep plant replaced two coal pumps, a centrifugal dryer, and a turboblower. Also, the continuous handling system’s equipment has been repaired. By the end of this year, another centrifuge and two conveyors will be replaced.
