At Astrakhangazprom, a daughter company of worldwide largest Russian natural gas producer Gazprom, SCHADE Lagertechnik GmbH (Herne) recently commissioned two combined portal scraper reclaimers for stacking and reclaiming sulphur prills at two stockyards with a capacity of 2 times 150,000 tons. With a rail track of 65m each, the combined stacker/portal scraper reclaimers are two of the largest machines which SCHADE ever supplied to a customer in the petrochemical industry.
The two machines with a stacking capacity of 300 t/h and a reclaiming capacity of 600 t/h ensure the smooth material handling on both stockyards. The stackers take over the sulphur prills produced from the natural gas and stack them on the corresponding pile. The reclaimer is used to load rail wagons with the fertilizer.
Normally, a bulk material stockyard is operated in such a way that simultaneous stacking and reclaiming is possible. Usually, this involves two separate machines such as a belt stacker for building up the pile and a portal scraper reclaimer for removing material from the pile. As the stacking and reclaiming processes on the stockyards in Astrakhan do not need to be carried out simultaneously, their combination in one machine is possible. This combined machine results in considerable savings not only as regards the investment cost but also the operating cost.
