The process of sizing a rotary dryer is one of precise engineering involving complex calculations and meticulous design. While the process is not well simplified into a few paragraphs, an explanation can be offered as to some of the concepts behind the process of rotary Continue reading →
Rotary dryers offer a highly flexible solution to drying bulk solids ranging from specialty chemicals to minerals and ores. But with all this flexibility and opportunity for customization often comes confusion on what configuration will provide the most efficient solution for the job at hand. Continue reading →
Rotary dryer misalignment is oftentimes the result of improper base installation. Misalignment in the base will quickly spread through the rest of the drum, causing wear and damage to other drum components. In addition, misalignment can occur naturally over time as part of normal rotary Continue reading →
Drying is a critical aspect of mineral processing; throughout the journey from ore to end product, the ability to control moisture content helps to reduce shipping costs, streamline downstream processing, and produce a refined product. While mineral dryers may appear the same as other industrial Continue reading →
Although it may seem like a good opportunity for cost savings, a one-size-fits-all approach to rotary dryer design typically yields a dryer that is ill-equipped, resulting in a number of unseen costs associated with product that is under-dried, over-dried, or in most cases, a mix Continue reading →
This week’s photo, taken in the FEECO Fabrication facility, shows a FEECO employee using a laser shaft alignment tool to properly align the coupling on the shafts of a drive assembly. The coupling joins the shafts between the drive motor and reducer. The shafts are Continue reading →
Potash, or potassium-bearing ore, is primarily used for agricultural purposes, serving as a source of soluble potassium, one of the three primary plant nutrients required to ensure the growth of healthy and nutritious crops. Mined potash requires processing in order to make the potassium readily Continue reading →
The best way to control material build-up in a rotary dryer is to prevent it in the first place. Custom Flight Design. Build-up can be prevented through the design of less aggressive flights, or material lifters. Material tends to build-up in sharp corners, and a Continue reading →
Today’s photo highlights advancing flights in a rotary dryer. Advancing flights help to move, or advance material into a rotary dryer to prevent buildup near the wet feed discharge. Additionally, advancing flights give the material a chance to dry before they hit the next flights; Continue reading →
Rotary drums, including dryers, coolers, and kilns, are an integral part of the many industrial processes that shape our world. From fertilizer and chemical production, to ore beneficiation and even consumer products, rotary drums provide a reliable, high-capacity setting for accomplishing a number of necessary Continue reading →
