The rotary dryer is the industrial dryer of choice for everything from minerals and ores to fertilizers and specialty chemicals. One decision buyers are often faced with in selecting a rotary dryer for a given application, particularly when looking to dry high-moisture materials such as …
Catalyst regeneration via thermal desorption has emerged as a solution for industries grappling with spent catalysts, which pose liability risks and waste management challenges. As processors seek to lower operating costs and minimize their environmental footprint, many are turning to catalyst regeneration through this thermal …
Today’s photo shows the gear mesh of a gear and pinion drive, the mechanism that causes a rotary drum to rotate. The face of the teeth here are worn, an indication that the gear should be replaced, or they may break off. In most cases, replacement …
The drive assembly is the component that causes a rotary kiln to rotate. While a variety of drive assembly arrangements are available, the selection of one type over the other is dependent on the drive horsepower and the size of the kiln. FEECO offers the …
Bulk solids processing is perhaps the most fundamental aspect of modern industry. Each and every day, bulk solids are handled and processed by the ton to convert mined ores into refined metals, produce market-ready products from raw materials, and so much more – all to …
This week’s photo highlights a girth gear run-out procedure in action. A black strap (pictured) is mounted along the gear’s teeth. A dial indicator follows the strap’s path, and measures the tip of the teeth along the strap. This procedure reveals the amount of wear …
Each week on our home page, we feature three articles that are highly relevant under the current market circumstances. This week, we’re highlighting: The Role of the Calciner in Producing Soda Ash The Role of the Calciner in Producing Soda Ash, looks at the processing …
Red mud, also commonly called bauxite residue, is a waste product left over from the Bayer process, in which alumina is extracted from bauxite ore. Produced in mass quantities (estimates hover around 1-2 tons of red mud per ton of alumina produced), red mud has …
The rotary kiln is an advanced thermal processing device used in an extensive number of applications, with new uses constantly being developed. As a cornerstone technique in engineering the raw materials and products our constantly evolving society depends on, the advanced thermal processing carried out …
Indirect rotary kilns, or rotary calciners, offer three major advantages over their direct-fired counterparts, as outlined below. FEECO is a leader in custom thermal processing equipment and solutions for both indirect and direct-fired rotary kilns. Our team of process engineers look forward to helping determine the …
