Rotary dryer misalignment is oftentimes the result of improper base installation. Misalignment in the base will quickly spread through the rest of the drum, causing wear and damage to other drum components. In addition, misalignment can occur naturally over time as part of normal rotary …
This weekโs photo shows two different rotary drum tire mounting styles: the wedged and pinned mount (at left), and the floating mount (at right). Traditionally, wedged and pinned mounts were used to mount the tire to the shell of the drum. And while they offer …
The addition of a coating drum to a granulation line has gained popularity in recent years as producers look to further specialize their products and control quality and performance metrics. Whether producing a fertilizer product or roofing granules, the addition of a coating drum gives …
Attrition transpires when agglomerates break down into fines- an undesirable occurrence that results in excess dust and waste product. It is commonly seen with granules produced via compaction granulation, and is caused by the rough, jagged edges rubbing against one another and wearing down the …
A pin mixer can be an incredibly valuable tool in a limestone pelletizing system, offering several benefits to both the process and the product. Made up of Calcium Carbonate and typically crushed prior to use, limestone intended for use as a soil amendment is processed …
In this weekโs photo, a FEECO Customer Service Engineer is checking for cracks in the refractory of a rotary kiln. Cracks periodically arise within the kilnโs refractory because certain areas are exposed to more direct heat. The area closest to the combustion chamber is the …
Agglomeration is frequently recognized as a process step that produces more marketable end products, such as fertilizers, pharmaceuticals, and food powders, among others. One overlooked application of agglomeration, however, is the treatment of materials headed to landfill. Before being disposed of, or taken to landfills, …
Pelleting and pelletizing are two terms often used interchangeably, though their processing methods do differ. Pelleting commonly refers to the extrusion process, where cylindrical pellets are formed by forcing material through a die. It is most often used with wood, fuel and feed products (such …
Todayโs photo highlights a rotary dryer in FEECOโs Fabrication Facility. The drum was recently painted, and will soon be ready for shipment. This particular dryer features our direct drive option, the mechanism that causes the drum to rotate. It eliminates the need for a girth …
When designing a gypsum pelletizing system, most attention focuses on larger equipment such as disc pelletizers or rotary dryers. However, the importance of a pin mixer for gypsum pelletizing should not be overlooked. Pin mixers offer numerous benefits such as solids mixing, densification, and granulation. …
