This week’s photo shows a raw and pelletized gypsum sample from the FEECO Innovation Center. Gypsum can present unique challenges, and for this reason, testing is often necessary to achieve successful gypsum processing. Customers come to the FEECO Innovation Center to test the feasibility of a …
Quality fabrication is one of the most influential factors in maximizing the life of a rotary drum, whether it is a rotary dryer, cooler, kiln, or granulator. One critical aspect of drum fabrication is the concentricity of the drum and its supporting tires (riding rings). …
Scrubbing is an integral washing step employed in the beneficiation of many types of ores and minerals, helping to remove contaminants and gangue and ultimately improve recovery of the target material. Rotary scrubbers are often used in this role; while a variety of equipment types …
This week’s photo shows limestone pellets. Agglomeration is the process of particle size enlargement – collecting material fines in a mass via pressure or non-pressure techniques. Agglomeration offers many benefits, from eliminating dust and preventing segregation, to increasing density and eradicating landfill wastes. Limestone is …
An adequate preventative maintenance plan is a major contributing factor to maximizing the service life of a rotary drum, be it a dryer, cooler, kiln, or granulator. Despite being a rugged piece of equipment, rotary drums require a careful balance of load on mechanical components …
Rotary drums are the industry standard for everything from granulating fertilizers, to drying, cooling, and even coating them. Throughout the US – and the world – this diverse type of equipment dots the landscape at both mine sites and fertilizer production facilities of all kinds. …
The trunnion wheel, also known as a trunnion roller, is a key structural component of any rotary drum base, be it a dryer, cooler, kiln or granulator. What trunnion wheels are available? FEECO supplies trunnion wheels in 4140 or 4340 stainless steel. Sizes are available …
Pelletized limestone is commonly used as a soil additive for agricultural purposes. Composed of calcium carbonate, this mineral neutralizes a soil’s acidity, raises the pH level, and improves the absorption of soil nutrients. While limestone is available in powdered form for agricultural applications, this formulation …
Drying plays an important role in the non-pressure agglomeration process, both before and after agglomeration. Pre-Drying Drying is often used as a method of pre-conditioning material before pelletization, to help prepare the material for agglomeration. Since moisture is added during the agglomeration process (in the …
Our photo this week shows a rotary ore agglomerator preparing for shipment. The drum, weighing in at around 55 Tons, is being lifted by a crane onto a base while it awaits shipment. Ore agglomerators are used in heap leaching processes around the world for …
