Rotary dryers are sized and designed around a material’s unique processing needs, or at least they should be. A custom rotary dryer will produce the most ideal results. The following material characteristics should be considered in sizing and designing a dryer: Moisture content, including inlet …
As traditional bedding options become increasingly unreliable, more farms are looking to Recycled Manure Solids (RMS) or Dried Manure Solids (DMS) as an alternative bedding material for livestock. Ongoing research and the number of farms successfully utilizing this approach have proven that both recycled and …
Rotary dryers are known as the workhorses of the industrial drying industry, but like any robust equipment, they are not immune to processing challenges. The challenges often vary on the specific material being processed, with some requiring additional preparation, and others, routine maintenance. Generally speaking, …
As large farms become the future of agriculture, the need for sustainable solutions in managing manure is becoming an ever-increasing focus. However, while large farms are learning to deal with the amount of manure they produce, significant opportunity lies in processing manure to produce products …
Various data points are measured during the rotary dryer feasibility tests conducted in FEECO’s Innovation Center, with the most common being: Inlet and outlet moisture content of the material. Inlet and outlet material temperature. Material feed rate. Residence time. Inlet process air temperature. Outlet gas …
This week’s photo features two lifter designs. Lifters, also known as fins or flights, are commonly added to the interior of a rotary dryer to assist in the industrial drying process. Their overall objective is to promote efficient heat transfer between the material and the …
Generally speaking, rotary dryers are the sand dryer of choice when it comes to frac sand, offering many benefits over other drying options. One reason rotary dryers are chosen over other dryer types is for their ability to accept large throughputs. Rotary dryers are high …
In this week’s photo, a crane is hoisting a rotary dryer onto a semi-truck bed. The semi-truck will travel at night from Green Bay, WI to Lacrosse, WI, and from there, will be loaded onto a barge. The dryer will then make its way down …
This week’s photo shows pellets inside of a rotary dryer. The image was taken at FEECO’s lab testing center, where dryers are often used both prior to and post agglomeration processing. Feedstock must be within an ideal moisture range in order for agglomeration to occur. …
Our photo this week is a rotary dryer. Rotary dryers are used in a variety of industries to dry materials prior to transportation, baggage and storage. They operate at temperatures between 800° – 1400°F and use internal flights to maximize heat transfer between the material …
