Cargotec has received an order for a Siwertell ship unloader type ST790-D from the Indian Farmers Fertiliser Cooperative (IFFCO), Paradeep Unit. The enclosed screw-type unloader will be used to discharge rock phosphate and sulphur at a rated capacity of 1,800 tonnes per hour.

Cargotec’s Siwertell Sulphur Safety System (4S) was developed to minimise the risk of explosions and detect fires. The 4S is designed to prevent sulphur dust explosions in the conveying line and to evacuate explosion pressure in case a dust explosion does occur, without causing damage to equipment and endangering the safety of operators, personnel and other facilities. To prevent explosions and fires, the Siwertell unit is equipped with nozzles that spray water at the inlet feeder and in the conveyor transfer points. An automatic lubrication system lubricates and cools end bearings and intermediate bearings.

A specially designed conveying line with stainless steel components ensures that a Siwertell unit is protected from corrosion and it is also practically maintenance-free. Components for IFFCO’s system will be manufactured in Sweden and China for erection on site in Paradeep Port, Orissa, India.  With a delivery time of 12 months, the unloader is expected to be in operation by early 2013.
