Cement Plant Wildegg, Jura Cement

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.
