JSC “Vostochny Port”, the largest Russian specialized port with hi-tech transshipment of coal and a member of the coal port holding “Managing Port Company", says it completed the installation of 8 receiving bunkers for 2 tandem-type railcar dumpers on Phase 3 of the Specialized Coal Complex.
Four bunkers were installed on each railcar dumper conveying coal from open gondola cars through the underground tunnels to the closed-type belt conveyors which deliver the production to the storage areas and the ship-loaders.
Over-bunker grates were installed to ensure even coal distribution to form its continuous flow and hinder the ingress of large lumps of coal (oversize) into the bunkers. The receiving conveyors and the vibrating feeders were installed to deliver coal from the bunkers to the conveyor belts. The installation of crushing and milling machines - designed to bring the frozen coal to the loose condition - is carried out to ensure continuous discharge of the open gondola cars.
The installation of the tandem-type railcar dumpers is scheduled for May 2018. The enclosed-type complex will be fitted with the high speed automatic doors at the places of entrance and exit of open gondola cars. It will be also equipped with aspiration systems and “dry mist” dust suppression system.
The equipment for the premises of the railcar dumpers was supplied by “Marubeni Corporation” under the contract for the packaged supply of the specialized equipment for Phase 3. The installation supervision is being performed by the Japanese corporation according to the trilateral memorandum with due consideration of implementing state-of-the-art technologies to ensure the environmental safety of production processes.
The cost of 2 railcar dumpers represents more than 7 million U.S. dollars. Equivalent railcar dumpers of an American manufacturer were installed in the existing Specialized Complex of “Vostochny Port”. They ensure a maximum discharge speed of four 70-ton open gondola railcars with coal – just within 3 minutes – and completely exclude the damage of the railcar fleet.
