Volumetric Dosing

STAG has gained an extensive experience with the volumetric dosing system. The system contains the dosing, the pneumatic conveying with product-specific air blast injector nozzle as well as the necessary air treatment. By the volumetric dosing the material discharge is only done due to the proportion of volume- and quantity. This is done by a Multi screw dosing unit which must be calibrated for individual customer requirements.

WtE Perlen

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).
