Main models of plastic feeders

Screw conveyors, also known as screw-type automatic feeders, use the screw conveying principle. Common models include the ZJF series (such as ZJF-300, ZJF-700, ZJF-1000), ZD-600, and JY-133.

Vacuum conveyors, also known as suction feeders, use the negative pressure suction principle. Common models include the SS300G and RL-300G. Powder screw conveyors are specifically designed for powders and small granular materials and are often made of stainless steel.
