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 …
Today’s photo highlights a rotary drum tire inspection. A digital caliper depth gauge (pictured) measures the depth of the grooves on the tire. If the grooves are too deep, as defined by the service technician, tire grinding may be proposed to resolve the issue. Grooves …
This week’s photo highlights a rotary kiln dam in 3D. Oftentimes, it is necessary to increase retention time and/or bed depth in a kiln. This is achieved through the use of a dam. A rotary kiln dam works by forcing material to build up behind …
This week’s photo highlights a sparger support system, or mounting bracket, inside of a coating drum. Spargers are commonly used in coating applications to coat pellets or granules after pelletization or compaction. Coating is done for various reasons, such as to change the color of …
Our photo this week is a 3D rotary cooler. Rotary coolers are a common equipment of choice when it comes to cooling bulk solids. They utilize direct contact between the material and cooling air, in combination with lifting flights, to maximize heat transfer between the material …
Today’s photo highlights a girth gear (left) and gear lubrication nozzle (right), both components of a rotary drum. The gear drive assembly is mounted on the outside of the shell circumference. It meshes with a small gear drive, and causes the rotary drum to rotate. …
This week’s photo is a hammer mill in 3D. The FEECO hammer mill is designed to reduce dry and semi-moist materials, specifically granulated or pelletized materials, to the product range of minus 4 mesh to plus 20 mesh. Commonly processed materials include aggregates, minerals, ores, …
This week’s photo highlights a rotary dryer’s direct drive assembly, the arrangement which causes the drum to rotate. The direct drive assembly is ideal for small to medium size drums running up to 75 horsepower. Here’s how it looks: A shaft is mounted to a …
This week’s photo shows a sample of a rotary drum’s spare parts. A housing to the trunnion wheel bearings is pictured left, and a graphite block is pictured right. Bearings, graphite blocks, thrust rollers, drive sprockets and more are all recommended spare parts for rotary …
This week’s photo is a granulation drum, or granulator, from the late 1950s. FEECO customizes granulation drums to meet each customer’s processing requirements and throughputs. Some drums, for example, are built with a specialized lining to protect against corrosive materials, while others are manufactured …
