Plastic Machine
>>> SDG Series Screw-Driven Feeding Machine

Application:         SDG series hopper plastic dryer has been our factory maturity products based on the digestion and absorption of abroad machine in the early eighties and with more than a decade of production improvement. there are 16 products in total series, applicable to use with the injection of various kinds of plastics and extrusion molding machine

*****The Complete Series Products Obtained The Title Of Quality Product on Ministry Of Light Industry Of P. R. China In 1990

*****We Are One Of Drafting Unit Of  Industrial Standard JB/T6494-92 <Hopper Type Plastic Dryer>

Advantage:   The structure of the equipment is simple, It does not need to land on the ground, for which the operational process is simplified and manpower is saved to facilitate the achievement of automation
●    After dried, The raw materials do not need to transport repeated, dust and other dirties are not easy to carry in, at the same time, the production quality is improved
●    The residence time for raw materials in barrel is short, it isn't apt to change colors, but at the same time apt to detect and control water content of raw materials after drying. 
●  Saving energy, compare to heating oven, 30% ~ 65% energy can be saved
●   After dully dried, the resin materials drop to molding machine with hot state, which can shorten the melting time of resin and increase the injection rate
   Stainless steel and aluminum alloy are used for manufacturing. keep raw material clean
Selection: Calculation can be in accordance with the injection amount of molding machine per hour, and the loading volume of the selected dryer should be slightly larger than the following calculated value
1. Dryer loading volume = injection volume of molding machine per hour *drying time of raw material
2. Drying time as follows:
Raw Material Drying Temperature Drying Time Raw Material Drying Temperature Drying Time
() (h) () (h)
Polyethylene PE 65-80 1 Polyformaldehyde 80-90 2
Polyethylene PP 65-80 1 Polystyrene PS 70-80 2
ABS 70-90 2.5 Polyvinyl Chloride PVC 65-80 1
Nylon 90-95 2.5 Polycarbonate PC 100-120 3

If the raw material are often changed in actual usage, then
the dryer loading volume=injection volume of molding machine per hour *2.5 (h)

principle: It adopts screw feeding, as long as the switch is actuated, screw rod will rotated and materials can be kept lifting from the bottom of the material tank to the discharge port. when charged to the full barrel, the charging screw rod will stop automatically
