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 …
As specialty fertilizer products become increasingly more commonplace, coating drums have emerged as a preferred way to incorporate beneficial additives and nutrients, reduce caking, and prevent dust in fertilizers, among other objectives. More recently, coating drums have also become recognized as an effective way to …
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 …
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 …
Rotary drums are central to many industrial processes, serving to dry, cool, agglomerate, heat, and even coat bulk solids. While in some cases production can be redirected to another drum, or simply taken offline when a mechanical failure occurs, in most cases, an out-of-commission rotary …
As the world looks to produce more crops on a shrinking amount of arable land, the soil amendment market continues to play a key role in meeting crop production goals. Limestone, an essential agronomic tool in managing soil pH for optimal crop production and nutrient …
This week’s photo shows a bulk density test in action. Here, our process expert is weighing raw material prior to processing in the Innovation Center. The ability to test bulk density ensures the product will meet the needs of its desired application. Bulk density is …
An effective maintenance program is indispensable to sustaining an efficient, productive limestone pelletizing operation. While maintenance is often overlooked, it should always be incorporated as part of a facility’s regular operation procedures. Limestone pelletizer plant maintenance ensures equipment reliability, preserves a safe work environment, and …
The industry making the material that has literally built the world around us is under increasing pressure to reduce emissions. The steel industry, which is responsible for an estimated seven percent of global CO2 emissions, has been the subject of numerous debates as of late, …
As products become more specialized and the demand for quality rises, coatings are becoming increasingly more important in industries working with bulk solids. Whether intended to reduce dust, mitigate caking, or enhance performance, the ability to coat granules and other particles gives producers greater control …
