Conditioning is a term used frequently in the field of bulk solids processing to describe a wide range of material treatments, be it for a raw material, a byproduct, or a finished product. Conditioning is an important component in the processing of bulk solids, allowing …
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 …
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 …
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. …
When considering the use of an industrial mixer, be it for pre-conditioning prior to a disc pelletizer, or for use as a stand-alone agglomeration unit, it is common to run into the question of which mixer will serve the process and material best: a pin …
This week’s photo highlights a micro-pelletized paint pigment sample from FEECO’s Innovation Center. Micro-pelletizing is the practice of agglomerating material fines into small pellets. Unlike traditional pelletizing, this process produces a smaller end-product- typically pellets between 20 to 60 mesh. It is most commonly used …
Potassium and ammonium salts are essential in supplementing crop nutritional requirements. While the granulation of these materials has traditionally been carried out via roll compaction, the demand for a more round and less angular product is causing some fertilizer producers to introduce an additional production …
