The Gravimetric Blenders are used in injection, extrusion and blowing production with more than one materials by different proportional mixture.
Machine starts working and dosing valve opens to release material by setting values. If controller detects the discharging quantity reached setting value, dosing valve closes up. If discharging quantity stays within allowed error range, machine will discharge next material. When all the material dosing completes, scale valve opens to release materials into the mixing tank. Mixer motor starts to mix. Mixing time can be settled by controller. Mixture will be discharged to the storage tank and ready for injection
