Demag Sets in Stone Crane Orders for Two Cement Stores

Terex Material Handling will equip two cement stores with Demag process cranes and storage controllers. After commissioning, planned for the first quarter of 2014, the two crane stores in Colombia and Mongolia will run automatically in 24/7 operation.

Lutz Dowy, vice president, sales and product management at Terex Material Handling said: “With our automated crane installations, we offer complete solutions for storage area management in the cement industry. Our customers benefit from robust crane technology that, with the highest availability, places the materials into storage and safeguards the production processes.”

On behalf of FL Smidth A/S, one of the world’s leading suppliers of machines and systems for the cement industry, Terex Material Handling is supplying two Demag process cranes for the new construction of an additives store in Mongolia. The two identical crane installations, with a span of 15.5m, travel on a crane runway of approximately 78m in length.

Equipped with a powered, clam-shell grab, the Demag process cranes will place the base materials—clay, iron ore, sand and gypsum—into storage, sorted correctly by type. With the store management system also included in the scope of delivery, the operator will be able to use the cranes independently around the clock.

Following the modernisation of a clinker store at its plant in Toluviejo, Colombia, the manufacturer, Cementos Argos S.A., will use Demag process crane technology. The crane installation ensures the placement into storage, transport, mixing and timely provision of various clinker and additives.

The installed and completely automated crane installation with 14t load capacity and 30m span also features scanner technology. A scanner installed on the crane bridge records the filling height of the materials in the storage area of approximately 2,900 square metres every time the crane travels. From this data the store management computer creates a height profile and steers the grab of the crane exactly over the transfer points in a time-saving manner. The fill levels are also permanently measured using scanner technology and transparent store management is ensured.
