South Korea: Voith has reported on a contract to engineer and install a belt conveyor drive and controller system for SsangYong Cement’s Donghae plant. Changes made by the engineering firm to two belt conveyors from the main limestone quarry to the plant managed to double the production of the quarry.
The engineering company installed new drive trains on the longer 12.8km SB500 belt conveyor, one of the longest single conveyors in the world. The installed power is now 2 x 1.2MW at the head and 1 x 1.2MW at the tail of the conveyor. The existing drives from the longer conveyor were used to double the number of drive trains on the shorter 2km SB200 conveyor. The new configuration of the SB200 drive system consists of 4 x 600kW installed power at the head equipped with new gearboxes. A Voith TurboBelt DriveControl system was also installed to reduce the start-up time of the longer conveyor by half, from originally over 10 minutes. The system includes active-load sharing, belt conveyor control, slip detection and remote service capability. It is also expected to extend the belt lifetime by reducing the mechanical stress as well as the dynamic impacts.
“Due to this retrofit project, we were able to reduce the working hours of plant workers, achieved cost savings, and a flexible operation is now possible. Thanks to Voith’s technical support and efforts, the plant will enjoy sustainable operations providing value to its community, its owner, and the employees,” said Dukgi Lee, General Manager of the plant.
Saudi Arabia: Yamama Saudi Cement has ordered two sets of clinker conveying equipment from Aumund.

Filter dust will be conveyed by Aumund chain bucket elevators optimally designed for low capacity. Two Aumund double chain bucket elevators with a capacity of 2300t/hr have been ordered per line as recirculating bucket elevators in the cement mill. The supply package for the two lines also includes six Aumund pan conveyors as well as various flat gates, silo discharge gates, telescopic chutes and cleaning conveyors.
Qatar: Qatar Primary Materials Company (QPMC) plans to inaugurate its new cement silo project in the first quarter of 2017. The project is located at the Port of Mesaieed and includes two cranes, two conveyor belts, 12 silos each with a storage capacity of 5000t and a total of 60,000t, according to the Gulf Times newspaper. The silos will have a discharge rate of 250t/hr with a total of 1000t/hr. QPMC’s chief executive Eisa al-Hammadi said that the silos were to ensure a ‘sustainable’ supply of cement in the country. The site is intended to store and discharge over 2Mt/yr of cement.
QPMC completed its Bulk Materials Handling System in late 2016, a 4.8km conveyor belt system connecting the Port of Mesaieed to storage areas. The conveyor operates at a speed of 3m/s allowing material to be transported to the destination in under 30 minutes. The building materials distributor says that the conveyor is the first in the Middle East and one of the longest in the world.
Egypt: Aumund has won a contract to supply clinker conveying equipment for six production lines. The tender is part of a project by Chengdu Design & Research Institute of Building Materials Industry (CDI), a subsidiary of Sinoma International Engineering, to build the 6000t/day lines for the government. No value has been released for the order.
The lines will each be equipped by Aumund with four 650t/hr BWG belt bucket elevators and three 550t/hr BWZ chain bucket elevators. The machinery package also includes four 170t/hr BWG-L belt bucket elevators, one 80t/hr BWZ-L chain bucket elevator and six 375t/hr pan conveyors for each of the six lines. Altogether the order comprises 108 machines.
The new project in Beni Suef is to be completed by the end of 2020. The pilot phase of the new production lines is due to start as early as December 2017. Aumund will supply the machines to Egypt in three deliveries, between April and June 2017.
Netherlands: Van Beek Schroeftransport and Penko Engineering have developed a screw conveyor that can monitor in real time how much product the screw is transporting. Flow on the screw can be set and the screw can also be programmed to stop upon reaching a pre-specified weight or to empty itself and then stop. During operation measurements such as the material speed (m/s), flow rate (kg/s) and transported volumes can be monitored. The weighing screw was exhibited for the first time at the Industrial Processing exhibition in Utrecht in the Netherlands in October 2016.
India: Aumund India has been awarded orders for 17 bucket elevators, eight silo discharge systems and one pan conveyor in connection to orders FLSmidth has received from Tamilnadu Cement, Akij Cement and Shah Cement.
Aumund India will deliver one type BW-ZL bucket elevator, one type BWG belt bucket elevator and three type BWG-GK belt bucket elevators instead of the conventional Aumund type BWZ bucket elevator for the Akij Cement project. For the Tamilnadu Cement project FLSmidth had specific design criteria and wanted a certain safety factor for the chain. So Aumund India provided an optimised solution, which met these specific criteria. It will deliver two type BW-ZL bucket elevators, eight type BWG bucket elevators, eight type SDI silo discharge systems and one type KZB deep drawn pan conveyor. For the Shah Cement project Aumund India will deliver two type BWZ bucket elevators.
Ivory Coast: Intercem has been awarded an additional order by Sea Invest for the raw material transport at the 8000t/day cement grinding and packing plant that the contractor is building for Cim Ivoire in Abidjan. The transport system will link an Eco Hopper to the clinker silos and the additive storage at the site. Commissioning is planned for the fourth quarter of 2017.
The order includes the delivery of trough belt conveyors as well as all related components and the transfer tower on an engineering, procurement and construction base including the piling, the foundation works, the steel construction, the cladding of the building, the roofing of the belt bridges, the necessary filters and chutes to the electrical equipment, installation and the commissioning.

Netherlands: Keith is promoting its new Freight Runner Conveyor, a conveying system that can be installed inside a truck trailer as part of its West Coast Tour in the US and worldwide. It is intended to replace the manual process of palletised cargo handling that requires a forklift operator and an employee with a pallet jack. The system can move up to 30t and it can load and or unload a full trailer in two minutes. The system is available in a hydraulic and electric driven motor.
Turkey: General contractor Bilim Makina has commissioned Beumer to supply and mount equipment at a cement plant project in Elazig. The order includes 13 bucket elevators for the transport of cement, clinker and raw meal, six apron conveyors and 13 silo discharge systems for clinker transport. The greenfield plant is expected to achieve a capacity of 5000t/day. Sycs İnşaar Çimento Madencilik is the user of this plant.
Two high-capacity belt bucket elevators with a centre distance of 133m each are included in the scope of supply. They are used for feeding the preheater tower with raw meal. Owing to the size of this plant, a conveying capacity of 500t/hr is achieved using steel wire belts.
The supply of the comprehensive technology has been completed. Beumer is now installing the plant.
Brazil: The Sempertrans division of the Semperit Group and the Agudio brand of Leitner have started operation of their ‘flyingbelt’ conveying system, a combination of ropeway and conveyor belt, at the LafargeHolcim cement plant in Barroso, Minas Gerais. The conveying belt is suspended on ropes connecting a limestone quarry to the plant. It can convey 1500t/hr of limestone at a height of up to 36m. The 7km belt is the longest of its kind in the world.
"With the Agudio ‘flyingbelt’ we have installed a very innovative bulk materials transportation system. The Sempertrans conveyor belt not only overcomes - at great height - terrain that can only be accessed with difficulty, it also transports material efficiently and in an environmentally-friendly way. More than 40 truck journeys are saved every hour," said Thomas Fahnemann, CEO of Semperit Group.
The order was produced in the Sempertrans plant in France and shipped to Brazil. The electricity consumption of the new conveyor equipment is only around one third of that of conventional ropeway systems and, instead of the previous maximum of 400t/hr, 1500t/hr of limestone can now be transported.
