PVC chemical Additives automatic weighing dosing machine for Rigid
& soft PVC extruder line
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.

Main Features of whole system:
* High Accuracy: it adopts top-quality weighing sensor and advanced
design to reach high accuracy according to the formula.
* Intelligent Speed Regulation:According to the weight of the
different additive in the formula, the system can adjust the
feeding speed automatically. The high power feeding motor is
installed in this system, so the feeding will be faster, stable and
accurate
* Reliable: The control system adopts international famous brand
Siemens products.
* Easy Installation: This system is composed of several individual
small silos. the cables between the silos and the control cabinet
are connected well before shipment. It is easy for the user to
install and use.
* Easy Operation:Friendly operation interface with diagram and
symbol for easy operation. The user doesn't need to revise the
program. The user could set parameters on the touch screen to meet
different requirement.
* Quality Guarantee:The silos are made of 304 stainless steel. The
electrics are from international famous brands that have CE or UL
certificate.
