The US has made an important step toward building a domestic supply chain of critical minerals with a recent commitment to mapping the nation’s resources. As one of the industry’s leading mineral processing equipment suppliers, we’re watching the situation closely. Here’s a look at what’s …
Pan pelletizer operation is oftentimes considered an art because of the many mechanical and process variables that must be properly combined to achieve the desired pellet characteristics. A trained operator is necessary to create the most efficient pelletization process, and the most ideal end-product. The …
Though far less common than the need to dry or thermally treat a bulk solid material, some process settings call for preheating a material in preparation of downstream processing. In achieving this objective and meeting the high tonnages associated with bulk solids processing, rotary dryers …
This week’s photo highlights one of FEECO’s many replacement/spare parts: the thrust roller. Thrust rollers are a standard component to any rotary drum, from rotary dryers and coolers, to granulators and kilns. They ride on the downhill and uphill edge of the tire, and are …
The process of sizing a rotary dryer is one of precise engineering involving complex calculations and meticulous design. While the process is not well simplified into a few paragraphs, an explanation can be offered as to some of the concepts behind the process of rotary …
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 …
When selecting the proper belt conveyor for your process needs, it is critical to consider the different types of conveyor belts (and belt cleaners) available. In order for a conveyor to operate at its full potential, the correct belting and cleaning options must be selected. …
This week’s photo comes from the FEECO Innovation Center, where a sample is ready for a solubility test. Solubility tests, or dissolving tests, look at how agglomerates behave in water. By submerging the agglomerated product in beakers of water, our process experts specifically analyze if …
Cycling and chemical incompatibility are the two main causes of refractory failure in a rotary kiln. Cycling Cycling is the heating up and cooling down of a rotary kiln, and it is the largest source of refractory failure. Refractory expands with the kiln as it …
A belt conveyor can come in many shapes and sizes and have an almost unlimited amount of interchangeable components, not to mention the number of add-ons available. Selecting the belt conveyor that best fits the processing system at hand can be overwhelming. The reason for …
