Based on their long cooperation in the area of conveying systems for thermal waste treatment plants, Hitachi Zosen Inova and STAG have already realised several projects together. In 2015, a completely new waste treatment plant featuring two lines has been put into operation in Perlen (CH).
The impact mill has been specially designed for breaking up agglomerated material within the bulk product. This application is mainly used in the treatment of boiler ash originating from incineration plants.
Each year STAG handles around 500 customer orders and achieves satisfied customers around the world. Here too, the focus lies on life-cycle-oriented warehousing as well as the plant availability. The experienced employees of the business area service are happy to answer any questions or suggestio
