Siwertell, part of Cargotec, has received an order from PT Asahimas Chemical, one of AGC Asahi Glass’s consolidated subsidiaries in Indonesia, to provide coal unloading and conveying equipment for installation at its chemical plant site in Cilegon, Indonesia. The coal is used to generate power for the plant. The order was booked into Cargotec’s 2016 first quarter order intake.
The contract calls for the delivery of an ST 790-D ship unloader with a rated capacity of 1,400tph (tonnes per hour) and two jetty belt conveyors. The order includes supervision of the construction and commissioning phase and spare parts appropriate for two years of operation. The components will be constructed in Sweden and China and are scheduled for delivery
by June 2017.
“An increasing number of operators around the world are appreciating the virtually dust-free nature of our unloaders, loaders and conveyors,” says Pierre O¨hrwall, Siwertell Sales Manager. “For this client, extremely clean coal handling is absolutely essential, because any significant amount of coal dust would have the potential to contaminate the chain of production processes at the chemical plants. As an indicator of the importance placed on cleanliness, the coal stock is stored undercover.
“Consequently, in this case a Siwertell system was almost self-selecting because of the high priority placed on exceptional environmental performance. Combining a Siwertell screw-type unloader with Siwertell’s totally enclosed belt conveyors arguably delivers the cleanest possible solution.”
Dust emissions at the transfer point from the unloader to the conveyors are controlled by Siwertell’s standard arrangements; the conveyors have cover belts and the unloader has belt lifters with dust-extraction filters.
“Asahimas Chemical will also benefit from Siwertell’s other well-known qualities including high performance, low energy demands, reliability, ease of operation, light weight construction and excellent, global after-sales service,” adds O¨hrwall.
