Aumund Asia Ltd is supplying a new generation 450 Series STORMAJOR for PT Asahimas Chemical’s operation in Indonesia.
The project was technically supported by Samson Materials Handling Ltd in the UK. The pre-assembly of the STORMAJOR is taking place in the workshops of Aumund Fördertechnik GmbH in Rheinberg, Germany. Delivery is planned for December 2020.
The new designed STORMAJOR is the combination of a Mobile Samson Material Feeder and an Outloading Boom, both mounted on the same chassis.
According to Aumund, the diverse options for stockpiling and loading offered by the STORMAJOR were the compelling factor in the order from PT Asahimas Chemical, a company that operates several chemical production plants in Cilegon in Banten Province, Java, Indonesia.
“In 2018, it built its own power plant, where the first new generation STORMAJOR will operate, serving an important purpose in minimising spontaneous combustion of coal by stockpiling the coal externally and bringing it back inside once it has cooled down,” stated Aumund.
The new generation of STORMAJOR will both simplify and speed up the process of moving coal. The machine is placed centrally between the stockpile and the covered storage area, from where it can both receive the coal from the diggers and stockpile it outside the covered storage area via the STORMAJOR Outloading Boom.
When the coal has cooled down the STORMAJOR turns in the opposite direction, receiving the coal back from the digger and transporting it back into the covered storage area.
This new process of utilising the STORMAJOR also decreases the amount of times the coal has to be handled, which reduces the material degradation keeping the quality of the coal intact, whilst operating at 300 tph. The STORMAJOR therefore increases the efficiency and productivity of the complete process cycle.
PT Asahimas Chemical selected a 450 Series STORMAJOR, which is the medium-sized model, for its operation in Indonesia. The bucket capacity for material discharge is approximately 4.5t and a conveying length of 11.5m.
The Outloading Boom is 27m long, has a luffing range from 2 to 30 degrees and a slewing range of 80 degrees (40 degrees in each direction). This STORMAJOR forms stockpiles of up to 11.75m in height.
