This bulk bag unloading station dispenses different types of carbon black in precise amounts to produce rubber products.
A “gain-in-weight” bulk bag unloading station with many unique features was designed. Because of the need to change the carbon blacks often, an intermediate frame complete with the unloader assembly was designed to allow the material to be changed, while there was material contained in the bulk bag. This is accomplished by simply closing a butterfly valve and lifting the frame out of a stationary feeding station. A second frame with a different material is then placed into the feeding station, the butterfly valve is opened, and the material change is complete.
The carbon black is metered out of the unloading station and into a plastic bin, which is indexed onto a scale. When initiated, the carbon black batching system will automatically dispense the proper amount of material (with an accuracy of +/- 0.1 lbs.) into a 75 pound batch. The complete process is accomplished in a dust-free environment.
New! Precisely mix and blend carbon black and other types of powders and pellets inside an intermediate bulk container, or IBC, using a patented cone valve.
