Self Contained Loaders

Use of Vacuum Loaders

Self-contained Vacuum Loaders are called by several names. They may be called Loaders, Hopper Loaders, Bin loaders, Plastics Loaders, Pellet Loaders, Regrind Loaders, Powder Loaders or Motor Loaders.

They all have an integral motor that creates a vacuum to convey plastic resin (in some form) from a nearby bulk container something like a drying hopper or blender bin. The pickup of the plastic material is usually accomplished by an aluminum or stainless steel tube, called a pickup wand, which is connected to a relatively short piece of flex hose attached to the vacuum loader. A small electro-mechanical control, usually ate the end of a pendant is set to manage load time, dump time and blowback (if that option is available). The loader motors may be of a brush type or “brushless”. The brushes only last about 350 hours so they have to be changed ( additional maintenance) and after about 4 brush changes, the commutator is usually worn out so the whole motor has to be replaced. As the several monikers for loaders imply, they are used to convey plastic pellets, plastic powders and plastic regrind.
