Feeders are usually suspended with a downslope of up to 10 degrees. At this downslope, the Model BF feeders can attain velocities of up to 100 feet per minute, depending upon material characteristics. Hopper Design and Feeder Capacity For vibratory feeders to perform at maximum capacities, it is important to have bins and hoppers

Loss-in-weight feeders are gravimetric feeders that directly measures the material's weight to achieve and maintain a predetermined feed rate. The feed rate is measured in units of weight per time (e.g. kg/h). This setpoint is programmed by the operator in the feeder control. A constant discharge of bulk material from the hopper is maintained ...

Apron Feeder Working Principle. Apron Feeders move materials from a hopper to their destination at a steady speed. They have a frame, undercarriage parts, a head shaft, tail shaft, flights, and a motor. The chain on the undercarriage wraps around the head and tail shafts, and the flights, attached to the chain, travel over undercarriage rollers.

Feeders are auxiliary equipment that dispense a measured amount of an ingredient—a resin, a colorant, or an additive—into resin entering a processing machine. The term "volumetric" refers to one way that a feeder measures and dispenses an ingredient. The other way is called "gravimetric.". Let's briefly look at both.
