Agglomeration (particle size enlargement) is widely used throughout the agriculture industry to minimize dust, improve handling and transportation characteristics, and enhance product performance – among other things. The practice offers benefits to everything from fertilizers and soil amendments, to animal feed products, and even pesticides. …
Our photo this week highlights a dial indicator. FEECO’s Customer Service Engineers use the dial indicator to measure rotary drum shell and tire run-out, or the degree to which a drum is out of its standard, cylindrical shape. Temperature changes can cause excess run-out. If …
Companies that use heap leaching to extract precious metals such as copper, gold, silver, or uranium ore have come to rely on FEECO for their production needs, from preliminary consultation and feasibility/materials testing, to custom equipment manufacturing and system design. FEECO can even offer a …
Variable Frequency Drives, or VFDs, are not a new technology, but only in recent decades have advancements in the field lowered many of the barriers associated with widespread VFD use, allowing their application in a range of settings. A recent market study anticipates that the …
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 …
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 …
The shell is the central component of any type of rotary drum equipment, from rotary drum dryers, coolers, and kilns, to granulators and coating drums. Since problems with the shell often end in catastrophic failure, early identification of an issue is essential to ensuring that …
The purchase of an agglomerator is a significant capital investment, making its careful selection and configuration pivotal to a reliable, long-term solution. The versatility of these machines, which lends them to processes ranging from fertilizer granulation to ore agglomeration, can raise a lot of questions …
The granulation drum, or granulator, is a diverse processing tool used throughout various industries to produce a granular product via wet granulation (also known as non-pressure, tumble-growth, or agitation agglomeration). The design of a commercial-scale granulation drum must take several factors into consideration in order …
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 …
