Case Study – Feed hopper for smelting plant in Norway

Location & Plannung period

Port of Norway
August 2022 - October 2023

conveyed material

Sulphates, oxides (clinker), aluminium hydrates, calcium florides

Special features

Grain sizes in µ range, high bulk density. To protect the environment, special emphasis is placed on reducing dust formation.

The hopper car runs on rails in the harbour and can be moved together with a transhipment dredger as needed. The dredger feeds the hopper with bulk materials that are needed for the zinc smelting plant and are delivered by ship.

The integrated extraction with filter system and special dust retention system in the bin prevents dust from developing in the surrounding area. Underneath the bin is a bin discharge conveyor, transporting material onto a stationary conveyor.

The sophisticated extraction system of the feed hopper continuously extracts dust-laden air. A rotary valve discharges the filtered dust onto a discharge belt and conveys it into the main material flow.

An additional special construction, the spillage board from Loibl, is used to collect spilled material during the transfer from ship to bin in order to guide it back into the ship. This protects the surrounding sea, so nature remains unaffected.

Environmental responsibility and sustainable business

Zinc is an essential raw material for numerous industries, which is usually delivered by ship. Investments in innovative conveyor and filter systems are crucial to protect people and nature and to maintain the economic viability of your plants in the long term.
