Success for Beumer Conveying & Loading Systems Division: Part 1

World Cement,

The Beumer group has used its newly created Conveying & Loading Systems (CL Systems) division to develop and implement complex system solutions throughout the world for different industries, such as mining and the cement industry. The team is made up of experienced staff from branches across the world who will work together on projects. This is demonstrated by the completion of three impressive projects.

Dr Andreas Echelmeyer, who has headed the Conveying and Loading Systems division in the Beumer Group at its headquarters in Beckum since August 2015, stated that "We can use our comprehensive expertise in system solutions to advise our customers and provide them with complete plant systems. Each industry poses its own unique challenges".

Most important is to listen to the customer and ask the correct questions, something which can only be done locally. Employees positioned around the world are therefore in close contact with the customer. They are familiar with the specific customs of the particular country, understand the language and are wise to the particular requirements of the market and the customer. They identify appropriate potential and any possible need for action. Operators for whom Beumer has successfully commissioned conveying plants includes the TPI Polene Public Company Ltd., the third largest cement producer in Thailand, which used this complex system solution to transport crushed limestone from the quarry to the blending bed.

Dr Echelmeyer was aware that "The challenge lay in the nature of the ground between the quarry and the cement plant. It was exceptionally demanding. We had to make allowances not only for numerous obstacles but also for a steep downhill section of the conveyor". The team designed a complex, but above all cost-effective, integrated system comprising a total of eight belt conveyors covering a distance of 6129 m. Beumer also supplied a PLC plant control system, transfer stations, filter systems and foreign body collectors.

The system is designed for a conveying capacity of 2200 tph. Key aspects of the limestone transportation system are two downhill belt conveyors operating in the generator mode, followed by a troughed belt conveyor with horizontal curves. The material passes from the crusher discharge belt the first two troughed belt conveyors. The material is then transferred to a long overland conveyor with a speed of 4.5 m/s by an accelerator belt with a speed of 2.6 m/s. Three more conveyors finally transport the material to the blending bed. A total of 640 kW/h generated energy is fed into the power grid from the down hill conveyors, meaning they make a substantial contribution to the cost-effective operation of the overall system.

"We have a great deal of experience with conveying systems that can negotiate horizontal and vertical curves and operate in the generator mode" explained Dr Echelmeyer. During the development it was necessary, for example, to ensure safe and carefully controlled stopping of the large belt system to avoid problems during unavoidable events, such as a power failure.

Beumer supplied four further belt systems with a total length of 989 m to deal with the discharge from the blending bed and supply the material to the raw mill feed hopper. The conveyors were built and installed in only 11 months. The commissioning phase lasted three months and was followed by performance tests. The team then handed over the entire plant to the customer. Dr Echelmeyer emphasised that "We supervised and monitored the installation and commissioning to ensure long-lasting, trouble-free, operation. This always forms part of our service". The standard scope of supply also includes intensive training of the operating and maintenance personnel.
