GatesThe sector gate, sector hatch and two-leaf gate are designed for cutting-off the material supply and can be used as a part of the multi-purpose proportioning complex or independently. They can be controlled by means of the automatic control systems or manually.
Proportioned materials are free-running components with grain size of max. 3 mm. Disk shutter is intended for cutting-off the material supply from the feeding device into the weighting tank upon command of the weigher control system. Operation conditions:
