This week’s photo highlights washboarding on a rotary drum tire. Washboarding is indicated by the vertical grooves that extend the length of the tire, and it is caused by abnormal skewing of the trunnion wheels, or trunnion wheel mis-alignment. FEECO offers a tire grinding service …
Pelletization is an agglomeration process whereby material fines are “grown” through a tumbling motion in the presence of a liquid binder or water. While all agglomeration processes can be customized to suit the unique needs of the material being processed, in general, it follows these …
Pin mixers are industrial mixing devices used to process fine materials in the presence of a binder. They are especially adept for micro-pelletizing and de-dusting applications. The following materials are often processed in a pin mixer. Mixing Bentonite clay Diatomaceous earth Fly ash Limestone Magnesium …
Some materials come with limitations that will steer the rotary dryer design process in one direction or another. For example, with materials that have the potential for combustion in certain settings, a direct fired dryer would not be the ideal option; an indirect dryer should …
