What is Attrition

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 Continue reading →

What are Indirect Coolers Used For

While indirect coolers are used far less commonly than their direct cooling counterparts, they are often the best solution in a few specialty applications. A direct cooler relies on direct contact between the material and chilled air in order to cool the material, which can Continue reading →

What is Micropelletizing

Micro-pelletizing is the process of agglomerating material fines into small pellets. This differs from traditional pelletizing, in that it produces much smaller pellets, typically around 20-60 mesh. Pin mixers are the equipment of choice when it comes to micro-pelletizing; they can be used as a Continue reading →

Rotary Dryer Advancing Flights

Advancing flights help move, or advance, the material into the rotary dryer to prevent buildup near the wet feed inlet. In addition, advancing flights allow the material to dry before it moves on to the next set of flights, a process that can help prevent sticking inside Continue reading →

What is the Difference Between a Rotary Dryer and a Rotary Kiln

Rotary dryers and rotary kilns share similar thermal processing functions, but each is intended for very different industrial applications. Rotary dryers operate at inlet temperatures between 600 and 1400ºF, and are predominately used to draw moisture out of a material. Rotary kilns, on the other Continue reading →

Rotary Drum vs. Disc Pelletizer

During the pursuit of an effective non-pressure agglomeration solution, the choice between a rotary drum and a disc pelletizer often arises. To help determine the best equipment for your material and process, the following should be taken into consideration: recycle, throughput, and maintenance. Recycle. One Continue reading →

What is the Role of Screening in Agglomeration

Screening is a process through which material or particles are segregated into groups based on their size. The undersize particles are segregated to one group, oversize particles in another, and on size yet another. Screening helps to ensure that feedstock is uniform and only material Continue reading →
