CONVEYING
conveyors . An 875 m straight conveyor connects the new conveyor system to the client ’ s preexisting plant infrastructure .
By integrating these systems , the Estonian mine will benefit from a highly efficient and reliable conveyor system capable of handling substantial material flow with minimal disruption . The new conveyor system is engineered to meet the high demands of the mining operation , including robust performance in cold and challenging conditions .
Some key technical specifications include a nominal Capacity : 2,000 t / h , with a peak capacity of 2,400 t / h , ensuring that the system can handle surges in material flow without compromising performance .
The belt type is ST2500 , a high-strength steel belt chosen for its durability and ability to withstand significant mechanical stress . The belt will move at a speed of 4 m / s , optimising material flow and reducing transportation time .
The system features two curves that allow it to navigate the terrain , minimising the need for costly infrastructure adjustments . The ground structure is designed to support the conveyor system securely , especially given the long distances involved . The system includes three crossings through metallic galleries , with lengths of 53 m and two at 35 m each , ensuring stable support as the conveyor crosses over challenging sections .
On components , the roller diameter is 159 mm , chosen to provide optimal support for the belt under heavy loads . The motorised drum diameter is 1,200 mm , which plays a crucial role in driving the conveyor efficiently . A winch tensioning system was installed to ensure the belt remains properly tensioned at all times , preventing sagging or excess wear .
The system is engineered to operate effectively in extreme conditions , withstanding temperatures as low as -35 ° C , alongside heavy snow .
Yvon Clouard , Sales Manager at RBL REI told IM : “ One of the most notable aspects of this project is the level of customisation tailored to the client ’ s specific technical and budgetary requirements . To help manage costs while maintaining high performance , the procurement and installation of the conveyor belt fall under the client ’ s scope of responsibility . This collaborative approach allows the client to maintain control over key elements of the project while benefiting from RBL REI ' s expertise in the engineering and installation of the overall system .”
RBL REI ’ s ability to execute this large-scale project efficiently is supported by its collaboration with FIPE , its sister company specialising in steel structures . FIPE has already manufactured and delivered all of the required structural components within Europe , ensuring
Part of the RBI REI 6.175 km conveyor system for an oil shale mining customer in Estonia
the project remains on schedule . The entire conveyor system is expected to be commissioned by June / July 2025 , marking a significant milestone for both RBL REI and the client .
