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 …

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 …
Favorable market conditions have again brought rise to a boom centered around the quartz sand used in the hydraulic fracturing process; rig counts are up and the amount of sand employed per well is the highest it’s ever been, with one industry expert anticipating 2018 …
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. When processing in a direct-fired rotary kiln, fine materials can become entrained in the gas and carried out to the baghouse. An indirect kiln avoids this issue because …
