PEGE liquid loss in weight feeder can sucessfully dose or feed Maleic Anhydride from solid shape to be liquid type spraying

Maleic AnHydride is a very important chemical material for some engineering plastic manufacturers to make good quality plastic material, they always want to dose the malec anhydride into their extruder to increase the product performance.

But to dose maleic anhydride is not easy, its shape in normal temperature is solid, when the temperature rises to 70°C, it will be liquid type, its visidity or stickness is not good. And it has pungent smell which is very tough for workers.

To feed the Maleic Anhydride, we need to heating the Maleic, keeping a sufficient pressure, ensure a precise feeding accuracy.

In whole liquid loss in weight system. There is temperature controller for heating.

From above photos we can see that a full liquid gravimetric feeder for Maleic Anhydride feeding includes:

1. Hydraulic Diaphragm Pump for pulling up the material from the weighing hopper.
2. Weighing hopper
3. Load Cell
4. Refilling hopper 
5. Temperature controller 
6. Pipeline for transitting, gaugues to monitor the pressure
7. Nozzel for spraying the liquid
8. Electrical cabinet to control the precision transportation.
