When it comes to working with organic materials, testing is critical because not all animal manures are the same. The manure FEECO typically works with varies from cattle, hog or chicken, composted, digested or raw, and screened or unscreened. The moisture rates also vary and …
This week’s photo highlights wear on a rotary dryer’s downhill thrust roller. Thrust rollers ride on the uphill and downhill edges of the rotary drum tire. They function to keep the drum from drifting, and ideally make little to no contact with the tire. In …
Compaction granulation is an immensely effective, cost-efficient agglomeration option for potash and other salts, and it is an ideal method used to turn potash fines into a usable fertilizer product. Compaction granulation operates under the principle that under extreme pressure, some materials will adhere to themselves …

US and Canada Agree to Reduce Phosphorous Targets 40% by 2025 in an Effort to Protect Lake Erie In an effort to reduce dead zones in the center of Lake Erie, as well as preserve ecosystems, the United States and Canada have agreed to limit …
This week’s photo shows a cattle manure sample in its raw state (left) and granulated form (right). FEECO’s Process Experts transformed the manure into fortified, dry fertilizer granules. There are several on-farm practices that affect the makeup of manure: animal species, feed, manure handling practices, …
A growing problem is being seen in soils across the globe: crop nutrient value is in severe decline, and soils are losing their ability to produce the nutrient-rich produce we need to stay healthy. In short, after generations of taking more from our soil than …
This week’s photo highlights potash granules produced via compaction (left) and granules produced via pelletizing (right). Potash compaction granulation and pelletization are two agglomeration methods, each offering a set of advantages and disadvantages. Compaction granulation does not use a binder or drying during processing, a …
Various data points are measured during the rotary dryer feasibility tests conducted in FEECO’s Innovation Center, with the most common being: The factors noted above are tracked, analyzed, and then adjusted, as needed, throughout the drying process. The ability to measure such data points before, …
