US-based Vortex has developed a new Grain Ship Loading Spout capable of loading 4,000 cubic metres per hour.
“When properly applied using proprietary engineering controls (headchute, spout, dust collection, etc.), the Vortex Grain Ship Loading Spout is specifically designed for dust-free grain loading, thereby protecting the port’s nearby neighbourhoods, waterways and other surrounding ecosystems from grain dust emissions into the atmosphere,” the company said.
The Vortex Grain Ship Loading Spout is equipped with a Discharge Filtration System for improved dust management at the point of discharge. It is specifically designed to displace dust-laden air from its source, separate dusts from the air, exhaust the cleaned air into the atmosphere, and re-entrain the filtered dusts back down into the load.
Vortex said its Filtration Systems are “active units”, meaning air withdrawal forcibly pulls displaced air and dusts through the filter cartridges, in order to perform a filtration process.
The Grain Ship Loading Spouts are made-to-order to fulfil each customer’s application requirements. This includes overall spout size to meet load rate capacity requirements, vertical travel distance requirements, and other considerations for application parameters.
Vortex Grain Ship Loading Spouts are constructed from telescoping tubes that slide into one another as the spout retracts. In doing so, the spout’s overall height is reduced to allow bulk carriers safe entry and exit at the port.
The spout’s telescoping tubes are constructed from durable metal materials. This is designed to protect the spout from the elements of its surrounding environment, to addresses wear and abrasion from the grain(s) handled, and to provide stability in spouts with especially long vertical travel distances.
The loading spout utilises a two cable, dual-drum, two-part reeving hoist drive system. Redundant features are included to limit travel at both the upper and lower limits, as well as over-speed and under-speed conditions and cable tension monitoring. The winch system is designed at 5:1 service factor.
“The most critical features of shiploading equipment are reliability and environmental safety,” explained Mark Schaberg, chief engineer at Vortex.
“Nowadays, ports worldwide consider pollution prevention a primary objective – paying special mind to reducing dust emissions and preventing cargo overflow or spillage. To address these concerns, it is critical to incorporate sophisticated engineering controls and dust control measures to provide the best available technology to our customers.”
