Pelletizer plant process audits provide a valuable tool to plant managers struggling with changes in production, under-performance, yield, and more; even for those pelletizing plants performing well, a process audit can reveal inefficiencies that when corrected, can significantly add to the bottom line. The following …
This week’s photo highlights a ball and tube knocking system. Knocking systems are often implemented to combat build-up inside of a rotary dryer. The systems are usually externally fitted on the inlet end of the dryer, where the incoming material is most wet and sticky. …
Rotary drum tires, or riding rings, are one of the primary support components of a rotary drum, resting on trunnion wheels and allowing rotation of the unit on its base. As technology has advanced, the approach to mounting drum tires has evolved, with each change …
The bulk material handling equipment employed in any operation, be it frac sand processing, potash mining, or other industrial endeavor, is a critical part of operational efficiency. Troughed belt conveyors serve to move material around a facility in seamless fluidity for maximum efficiency. But what …
A pneumatic hammer knocking system is designed to control material build-up inside of a rotary drum. The hammer is mounted above a strike plate on the drum, and delivers an adjustable amount of force as set by the operator. This force “knocks” the drum and …
Reconditioning or resurfacing of rotary drum tires (riding rings) and trunnion wheels via grinding is one of the most important maintenance procedures carried out on rotary equipment such as dryers, coolers, and kilns. While restoring these load-bearing surfaces is a common practice, many questions often …
Our photo this week highlights a dial indicator. FEECO’s Customer Service Engineers use the dial indicator to measure rotary drum shell and tire run-out, or the degree to which a drum is out of its standard, cylindrical shape. Temperature changes can cause excess run-out. If …
Problems encountered with troughed belt conveyors have the potential to injure employees, shut down the production line, and incur substantial costs in repairs and production losses. Choosing a reputable conveyor manufacturer and having a system designed around the unique needs of the specific handling application …
The circumference of the inside diameter of a rotary drum tire is larger than the circumference of the outside diameter of the shell, and therefore the tire will not make a complete revolution at the same time as the shell. This difference per revolution between …
