Today’s photo highlights a trunnion wheel and thrust rollers. The 3D image was produced by FEECO’s in-house design team. Trunnion wheels support the weight of a rotary drum, be it a dryer, cooler, kiln, or granulator. Most importantly, they provide a place for the tire …
Drying plays a critical role in the agglomeration process. When used prior to agglomeration, drying prepares material feedstock for agglomerate formation, and has a direct effect on how material will perform during agglomeration. Used after agglomeration, drying cures pellets into their final, strong form. In …
Tolling, or toll processing, is becoming an increasingly common approach to meeting new or expanding production requirements. Further, the role of the tolling facility is evolving and expanding beyond simple production runs. Whether producers are looking to develop a new product, expedite the commercialization process, …
Sintering is the process of heating a material to a point just before melting via a rotary kiln. The objective here is to use the high internal temperature of the rotary kiln to increase the strength of the material. The most common use of this …
Rotary drum dryers are an essential production tool in a variety of industrial settings. From ore drying to fertilizer and soil amendment production, rotary dryers are used to process thousands of tons of material each and every day throughout nearly every industry imaginable. While the …
This week’s photo highlights the interior of a batch rotary kiln. The rod-like structures at the bottom of the image (labeled “C”) are two thermocouples. They are typically used in the kiln to measure bed and exhaust gas temperatures. The upper rod is an airline …
Indirect-fired rotary kilns, also commonly called calciners, are a specialized thermal processing machine used to cause chemical reactions and phase changes in materials for a variety of industrial purposes. Used in settings where the processing environment must be kept inert, or where entrainment of fines …
From moving ore at the mine site, to storing finished product, the fertilizer industry relies on bulk material handling equipment to keep processes running and product moving around the clock. This heavy demand, combined with some of the specific challenges fertilizers present, requires expertly designed …
The spray system on a disc pelletizer is critical to the success of the overall agglomeration process. The spray system dispenses the binding agent onto the material fines as the disc rotates. If not properly maintained, product quality can be easily affected, and process upsets …
What is Metallurgical Coke? Aka: coke, met coke Metallurgical coke is created through the destructive distillation of coal or coal blends. This thermal treatment drives off volatile components and leaves behind a solid carbon material (note that this is different from petroleum coke, which is …
