With several factors at play, demand for roofing granules has gone through the proverbial roof, and manufacturers are doing everything they can to keep up. This surge in demand, combined with the abrasive nature of roofing granules, has put added strain on roofing granule production Continue reading →
Today’s photo highlights a refurbished tire and trunnion wheel. Rotary drum tires and trunnion wheels can become worn over time, resulting in a variety of unwanted characteristics such as pitting, spalling and timing marks. If the wear is left untreated, the weight of the drum Continue reading →
Precipitated calcium carbonate is a byproduct of the sugar industry, produced during the purification of sugar from beets. This waste has long presented a management problem for sugar producers. As many are discovering, however, by pelletizing precipitated calcium carbonate, they are able to recover value Continue reading →
FEECO offers a variety of options in drive assemblies for your rotary dryer, cooler, kiln, or granulation drum, all selected based on the requirements of the application. Chain and Sprocket Drive Assembly Chain and sprocket drive assemblies are ideal for smaller drums running up to Continue reading →
The addition of a rotary agglomerator to the heap leaching process can provide exceptional benefits to the operation as a whole. Agglomerated ore fines are uniform in shape, allowing the leaching solution to more easily permeate through the heap. Additionally, the leaching solution can be Continue reading →
Pelletizing is a valuable tool in managing the properties of bulk solids. From flowability to bulk density and so much more, pelletizing gives producers in nearly every industry a way to control the handling and performance characteristics of their bulk solids. And while pelletizing provides Continue reading →
Rotary drums are used throughout a number of industries to carry out a range of different objectives, from conditioning to granulation (agglomeration), mixing, and coating. Part of their diverse applicability lies in the ability to customize their internals for a truly optimized processing solution. In Continue reading →
This week’s photo shows a rotary drum gear before and after replacement. The gear on the left is exhibiting excessive wear and inadequate lubrication. This is an example of extreme wear, and was caused by tramp material entering the gear mesh. At right, the gear Continue reading →
This week’s photo comes from the FEECO Fabrication Center, and shows a bearing being mounted onto an adapter with the help of a hydraulic nut. Bearings are part of the support structure for a rotary drum, located on trunnion bases, with the pinion shaft sitting Continue reading →
Agglomeration drums and granulation drums are two of many terms used to describe rotary drum equipment. Granulation drums are typically used in the agricultural industry for fertilizer production. The tumbling motion inside of the drum creates uniform fertilizer granules that are easy to handle and Continue reading →
