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.
