FEECO’s rotary dryers and kilns can accommodate numerous fuel sources. The chart below highlights the equipment and their available fuel source options: Natural Gas/Propane Fuel Oil Electricity Biomass Combustion Waste Heat Biogas Direct Rotary Dryer x x x x x Indirect Rotary Dryer x x …
To process biomass into biocoal, residuals from the forest products industry are first dried in a rotary dryer to reduce the moisture content and improve combustion. Next, the dried biomass is processed in the oxygen-free environment of an indirect rotary kiln to remove volatile components. …
Manure can be processed into a bedding product known as recycled manure solids (RMS). Recycled manure solids can further be processed into dried manure solids (DMS), a product with reduced moisture and pathogen content which is ideal for use as a bedding product. Bedding recovery …
The process of converting biomass to activated carbon can vary depending on the source and characteristics of the feedstock material, and the wanted end-product characteristics. This process is outlined in the stages below: Drying. Biomass must first be dried, most often via a rotary dryer, …
Proppants are hard microspheres that are injected into well bores to “prop” open rock fissures, allowing oil and natural gas to flow out. While frac sand is the most commonly used proppant, ceramic proppants offer a tailored solution in demanding drilling settings. Greater crush strength. …
A sieve analysis measures particle size distribution, and more specifically, what percentage of on-size, over-size and under-size pellets are produced from the agglomeration process. The analysis is an important part of agglomerate process and product development, as it confirms whether or not the agglomeration process …
There are numerous characteristics that make raw manure an unideal feedstock for granulation. Pre-conditioning manure must take place before the manure can be effectively used as a feedstock for optimal granulation to occur. Pre-conditioning focuses on: Particle size distribution: Large particles need to be removed …
The FEECO Innovation Center offers a variety of agglomeration test work to help develop new products, optimize current processes and more. The following highlights our agglomeration testing capabilities: NON-PRESSURE Pelletizing (rotary drum or disc pelletizer): A wet process where material fines are rolled into pellet …
Biosolids granulation is the transformation of biosolids into a granular product that is nearly odor-free and rich in nutrients. The diagram below highlights a mixer to dryer granulation setup (click to enlarge). Part one of the process takes place in a mixer, generally in a …
Pressure agglomeration relies on extreme pressure to force particles together into a desired shape. This includes the following techniques: compaction, briquetting, extrusion, tableting and molding. Non-pressure agglomeration, also known as tumble growth agglomeration, relies on a binding agent and the phenomenon of coalescence to create …
