Powder hopper loaders economically and efficiently load free-
flowing pellets or granular materials from supply containers into 
machine bins or other receivers. They are a modular, stainless steel 
component design using significant operational advantages. 
They’re engineered construction permits easier cleaning and 
maintenance, and they can be quickly and easily reconfigured to 
accommodate future production requirements. Simple electrical 
and compressed air connections are all that’s needed for operation; 
central vacuum systems are not necessary. 

 

Powder hopper loaders use an integral-mount three-stage 
centrifugal motor with a quick-disconnect power cord. The 
receiver-mounted junction box is pre-wired to the field-mounted  
control box. The powder hopper loaderfeatures a high-flow 
blowback valve to enhance cleaning its acrylic/mesh flat filter, 
providing excellent filtration of conveying air.  Powder hopper 
loaders also feature a counter-weighed flapper assembly. 

 

Powder hopper loaders are efficient conveyers of free-flowing 
powder, pelletized or granular materials.  They are typically used 
to convey material from supply containers into machine bins or 
other receivers. You can customize operation by adjusting 
operating parameters accessible through a menu system built into 
the control. Simple electrical and compressed air connections are 
all that’s needed for operation; a central vacuum system is not 
necessary.
