Premier Pneumatics Inc. of Salina, Kan., is offering a gravimetric version of its ProRate and ProRate II feeders.
The feed auger's speed is continuously adjusted to maintain the desired feed rate, even when bulk density changes, so the feeder does not need to be calibrated, the company said.
A new controller runs as many as eight feeders with a total capacity up to 25,000 pounds an hour.
Premier also said a single operator can unload powdered materials and resin from air-slide rail cars, using its air-slide car unloader. The portable device is balanced on two pneumatic wheels. Four connecting clamps hold it in place, making a tight seal.
