Sweden: UK-based Samson Materials Handling is supplying an Eco Hopper product for installation at the Port of Slite in Gotland. The hopper will be designed to receive clinker, limestone, coal and refuse-derived (RDF) fuel pellets. These materials will be unloaded at the quay area via crane grabs. The hopper will then discharge direct to trucks via a telescopic chute.

The Eco Hopper installation under normal operating conditions and based on the client’s grab sizes and cycle time, will achieve peak discharging rates of: 353t/hr - based on clinker with a bulk density of 1.4 t/m³; 454t/hr - based on limestone with a bulk material density range of 1.8 t/m³; and 420t/hr - based on RDF Pellets with a bulk material density of 0.6 t/m³.

The Eco Hopper product design concept comprises of a specialised reception hopper unit incorporating Integral filter arrangement with a reverse jet filter media cleaning system which returns all material back in to the material stream. In addition, the inlet system of the hopper is based on the Samson Flex-Flap design which reduces the volume of air necessary to control dust both from the opening grab and displaced air from material falling into the inner hopper below. This contributes to the reduction of airflow reducing filter and power requirements of the equipment.

Commissioning and operator training will be provided by Aumund Group Field Services.

India: Aumund Engineering India has been selected by ACC to refurbish a 175.3m high bucket elevator, the tallest in the world. The elevator is installed at ACC’s Wadi Cement plant in Karnataka where it is used for raw meal pre-heater transport at a rate of 600t/hr.

Originally, the machine was fitted with a steel cord belt of width 1320mm and tension rating of 3150N/mm. Aumund has decided to offer an alternative based on its own design concept resulting in a belt width of 1300mm but with higher tension rating of 4000N/mm with a bucket size of 1250mm at bucket spacing of 450mm. The Aumund belt concept will use continuous close pitch longitudinal ropes without rope free bucket mounting spaces. However, it will use additional wire ropes running laterally across the width of the belt adding lateral stiffness without significantly changing the belt longitudinal flexibility. This cross-stabilised construction is intended to improve stability to the belt with improved bucket fixing.

To make the necessary belt punching, Aumund has developed a special punching machine design which gives clean fixing holes that are accurately aligned relative to the belt edge and at precisely the correct pitch. The belt is held in a cassette and advanced automatically under the punching frame using a precision encoder to measure the pitch. The belts are prepared at the Aumund production in Rheinberg, Germany and shipped to site at the exact required dimensions including a prepared joint and the required clamping connection.

In addition to the new belt the elevator will also be fitted with new drive pulley including friction linings and rubber bucket mounting strips. The casings, inlet and outlet plus the complete drive unit remain unchanged.
No commissioning date for the project has been announced.

Switzerland: Jura Cement has installed a PREMAS 4.0 continuous monitoring system supplied by Aumund at its Wildegg cement plant. The system informs operators about the condition of the equipment used in cement production at the plant in real time via the PREMAS Cloud. It also provides service life estimates for critical components.

The Wildegg plant previously hosted a prototype PREMAS 4.0 in early 2020.

Head of Maintenance Ramona Keller said “We are convinced that predictive maintenance has a future. With PREMAS 4.0, we can better plan spare parts and maintenance, which has a positive effect on resources and costs. The PREMAS Portal is easy to use and very clear. It enables us to recognise immediately where there is a need for action, regardless of time and place."

Germany: Aumund has announced the launch of its PREMAS 360° packages. The three packages – basic, advanced, premium - combine quality Aumund all-around maintenance and inventory management support, extended warranties, physical inspections, cutting-edge Industry 4.0 monitoring of Aumund and other conveying equipment, technical training, emergency remote support and consultation programmes.

Managing Director Pietro de Michieli said “With PREMAS 360°, Aumund puts customer service to the forefront. Our goal is to reassure machine availability and reliability through the simplicity and flexibility of a fully bundled maintenance solution, to be a partner to our customers assisting them to reach operation excellence.”

Germany: Aumund has taken over all customer support services for KoWey conveyors and bucket elevators. The company assured customers that it would be there ‘anytime, worldwide’ to provide services, spare parts, conversions or support for their KoWey products.

India: UltraTech Cement has selected Germany-based Aumund to supply conveyors, elevators and feeders for its ‘Project Spring’ expansion project to increase its installed production capacity to 130Mt/yr of cement from 117Mt/yr.

The expansion project includes three integrated cement production units in Madhya Pradesh, Rajasthan and Chhattisgarh, each with capacities of up to 10,000t/day. For these kiln lines, Aumund India will supply clinker cooler extraction conveyors as well as the transfer conveyors to the clinker silos. Six cement grinding plants in various locations in India are also part of the capacity expansion plans.

Aumund will supply six pan conveyors, 11 Samson material feeders and 68 bucket elevators including up to 157m-high kiln feed bucket elevators, up to 2200t/hr roller press recirculation bucket elevators and clinker and cement handling bucket elevators, among other products. The order is one of the largest to date for Aumund India.

Cameroon: Aumund France has won a contract to supply three BWZ type bucket elevators with central chain, three BWG type belt bucket elevators and three Samson material feeders to Oyak Çimento’s upcoming plant near Kribi. When commissioned in September 2022, the plant will grind 100t/day of cement and 720t/day of calcined clay. ThyssenKrupp Industrial Solutions (France) is responsible for the overall design, supply and installation of equipment to the plant.

Senegal: Aumund Group says that it is supplying conveying equipment to a new production line that will be built at Ciments du Sahel’s Kirene plant. The order package includes 23 bucket elevators, seven pan conveyors, eleven drag chain conveyors, two Samson material feeders, four Centrex silo discharge machines and 19 silo discharge gates. The machines will operate in all stages of the production process, from raw materials discharge to conveying between the clinker silo and the cement mill, and in the packing plant. Supply will be made in several tranches between March and June 2021. Commissioning is planned for the first quarter of 2022.

China-based Sinoma International Engineering and its subsidiary CBMI Construction are the main contractors for the project. Aumund France and Aumund China, with support from Aumund Foerdertechnik, are the main divisions of Aumund working on the upgrade.

Ivory Coast: LafargeHolcim Côte d'Ivoire commissioned a new clinker discharge equipment at its Abidjan cement plant in June 2020. Aumund France supplied the equipment. It consists of a 75,000t-capacity silo, two Aumund KZB pan conveyors with ten gravity discharge gates, four Aumund GF belt conveyors and a dedusting system comprising five filters, as well as the complete electrics and automation package for the new discharge system. The supplier says that it also supervised installation and commissioning of the equipment.

Poland: Cementownia Warta has ordered a BPB-SF heavy-duty arched plate conveyor for the new limestone crushing facility at its Warta integrated cement plant from Germany-based Aumund. The supplier says that it will deliver the equipment before the end of 2020.

Aumund said that it has delivered “more than 20 machines” to the Warta plant since the producer placed its first order with the company in 1998. In 2020 it delivered five KZB pan conveyors of a total capacity of 2300t/hr as part of a project to construct a 120,000t steel-roofed concrete silo at the plant.
