Case Study – Feed hopper for zinc production plant in Norway
Port of Norway
Sulphates, oxides (clinker), aluminium hydrates, calcium florides
Grain sizes in µ range, high bulk density. To protect the environment, special emphasis is placed on reducing dust formation.
Retrofit project in Norway
Enclosed between mountains and fjords lies the zinc production factory for which Loibl Förderanlagen GmbH supplies a customised feed hopper system. Currently, the factory is being fundamentally modernised and extensively expanded.
The decades-old ship unloading plant is being replaced by a new one. The hopper car is an important part of the ship unloading process. It is the link between the handling dredger and the conveyor system. The feed hopper leads right up to the factory and is equipped with the most modern and innovative solutions, including a dust retention system to enable dust-free ship unloading.
The hopper car runs on rails in the harbour and can be moved together with a transhipment dredger as needed. The dredger feeds the bin with bulk materials that are needed for zinc production and are delivered by ship. The material is filled into the bin using a clamshell bucket.
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.
Wear resistant construction
A special plastic lining was selected for all surfaces in contact with material in order to improve wear resistance and gliding properties.
The dust retention system is likewise used in a reinforced version adapted to the customer's needs. An integrated sprinkler system takes care of cleaning the bin.
DUST REDUCTION & WATER PROTECTION
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.
Norway's beautiful harbour landscape should be preserved.

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.
