Coating drums are used throughout a number of industries to carry out particle coating applications. Commonly used after agglomerate processing, coating drums work by tumbling particles in a rotating drum and spraying them with the desired coating material. This may be to improve product handling, …
Some limestone pelletizing operations use a pin mixer to condition the material prior to processing it on a disc pelletizer. While this step is not required, adding a pin mixer to a limestone pelletization process offers many benefits to the overall agglomeration operation at hand, …
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 …
Although a multitude of industrial drying technologies are on the market, rotary dryers have persevered throughout the decades as the favored choice of equipment in many settings. The following describes the many reasons in which the rotary dryer is often preferred. Customization. Rotary dryers can …
FEECO’s conveyors can be designed with a variety of additional components to meet our customer’s exact specifications. We offer the following standard conveyor add-ons: Belt Trippers. Belt trippers are designed for material discharge control. They re-route the belting to discharge material at any point along …
While rotary dryers should be customized to yield optimal processing conditions around the material and drying needs at hand, the basis of a rotary dryer is often somewhat standard. The following is an overview of some of the standard components of a rotary dryer, as …
Refractory is specific to direct-fired rotary kilns, insulating and protecting the shell of the drum from high internal temperatures. It also functions to maintain heat retention. Many types of refractory exist, with the most common options being brick or castable. Brick is fired in a …
Many material characteristics, such as bulk density and specific heat, influence how the material will behave in the rotary kiln, and subsequently, how the kiln must be designed to produce the required results. The following material characteristics all influence the sizing and design of a …
When pelletization, granulation, or other agglomeration methods are employed, an additional and fairly common process is to coat agglomerates, or apply of a thin layer of material to the end product. Coating is done for a number of reasons, including: To change the agglomerate’s …
Green strength, also known as wet strength, refers to a pellet’s strength prior to drying. Pellets need a certain amount of strength to withstand the number of drop points during processing; this includes leaving the agglomeration equipment such as the pan pelletizer or drum agglomerator, …
