The additives automatic weighing machine can replace manual weighing of chemical additives and avoid the error caused by human misoperation. The machine can weighs 5 to 10 kinds of additives with high efficiency, high precision and no dust.
Application and introduction
The PVC additives auto weighing system – We developed this auto weighing system to instead of traditional old manual weighing. It could auto weigh the additives for the pvc extrusion production, such as, stearic acid, wax, titanium dioxide, whitener, carbon black etc. this auto weighing system could weigh the quantity for one batch usage automatically. This system could avoid the mistake of manual weighing and also keep the workshop clean. This system could auto weigh 5-12 kinds of powder or granules additives. The accuracy is within 10g.
