While to date the mobile conveyor has predominantly been used for reception of corrective materials and additives, nowadays alternative fuels play an ever more important role. They are employed worldwide by cement producers for the improvement of the carbon footprint as well as for cost reduction. Energy-bearing materials such as sewage sludge, residues from the manufacturing industry, biomass or industrial and domestic wastes with their widely varying material properties demand a flexible machinery concept. The SAMSON® has already tested this flexibility in many applications.
Early in 2012 the Secil plants Outao and C.M.P. Maceira will take delivery of two SAMSON® feeders (Fig.) for the handling of alternative fuels. At the end of March a SAMSON® 380 with a centre distance of 8.8 m and a conveying capacity of 90 t/h was supplied to C.M.P. Maceira. The machine which will be delivered to Secil-Outão in May is almost identical in construction but features a centre distance of 8 m. This confirms also for 2012 the long standing continuing trend of employing the SAMSON® feeder for the handling of alternative fuels.
In contrast to traditional transfer points, the machine not only receives the material but actively extracts it from the truck. In this way a controlled material flow is guaranteed irrespective of whether the materials are wet, sticky, dusty, heavy or abrasive. In addition, the machine requires no special structural preparation and is very quickly ready for operation at various locations. The machine also makes short-term intermediate material storage possible. The model which features a greater belt width can convey any bulk material reliably without bridge formation or spillage.
