At the site of Jura Cement in Wildegg, STAG has already implemented several conveying, silo and dosing projects for various bulk products.
In 2018, STAG is entrusted with the engineering, supply and putting into operation of a plant ensuring Fe(II) sulphate dosing into cement. Thanks to the many plants implemented by STAG throughout Europe, it is possible to rely on a standardised system.
Fe(II) sulphate is delivered by truck and pneumatically discharged into the silo. From the silo, a pressure conveying vessel transports the bulk material into a collector hopper of the gravimetric dosing system, which feeds the Fe(II) sulphate into the cement flow.
Applied Main Components
• e.g. rotary vane feeders
• The present bulk material ranks among the explosive substances. The plant has been engineered, built and commissioned according to the currently applicable requirements stipulated int the ATEX Directive 2014/34/EU.

STAG has gained an extensive experience with the gravimetric dosing system. The system contains the dosing, the pneumatic conveying with product-specific air blast injector nozzle as well as the necessary air treatment.
At the premises of Holcim (Süddeutschland) GmbH, STAG has implemented several projects concerning pneumatic and mechanical conveying, silo and dosing systems for different bulk products such as cement, iron oxide, hydrated lime, iron(II) sulphate, furnace dust, granulated slag, paper ash and brok
For financial and ecological reasons, silo rail wagons are increasingly used for transporting bulk products. The regional distribution of these bulk products is ensured by appropriate silo trucks. The transhipment systems constitute the link for transhipment of materials from rail to road.
