Whether you are using a rotary dryer, rotary kiln, or rotary cooler, there is one thing that all these instruments have in common: they all use methods of heat transfer to carry out their jobs. Heat transfer is how heat moves from one source to Continue reading →
Our photo this week shows an NPK fertilizer granulation plant. The photo was taken around the early 1960s and showcases a rotary dryer (the larger drum on the bottom), and a granulation drum (the smaller one above the dryer). Now a typical NPK granulation process, Continue reading →
This week’s highlighted resource is a project profile on three frac sand dryers used in an in-basin sand plant. The in-basin frac sand trend has been sweeping the industry. This project profile highlights an in-basin project FEECO worked with to provide three custom rotary dryers Continue reading →
The field of bulk solids is incredibly diverse, encompassing industries ranging from food and pharmaceuticals to fertilizers and process by-products. Processing bulk solids into a ready feedstock or end product can involve an array of process techniques, from crushing and mixing to high temperature techniques Continue reading →
Rotary dryers have a long history in many industries, but perhaps most notably, in the fertilizer industry, where they are an essential component in processing minerals for fertilizers at mine sites, and for producing many of the fertilizer products on the market today. Rotary Dryers Continue reading →
Rotary dryers are an essential component in a variety of industrial process settings. As the backbone of many industrial processes, efficiency, reliability, and longevity are key to a successful operation. For these reasons, when looking to purchase a rotary dryer, it is of the utmost Continue reading →
When it comes to buying an industrial dryer, people are often faced with the decision to choose between a rotary dryer, and a fluid bed dryer. Historically, rotary dryers have been used for more industrial applications, such as minerals, fertilizers, and aggregates, while fluid bed Continue reading →
Rotary dryers use a tumbling action in combination with a drying air in order to efficiently dry materials. Most often, rotary dryers are of the direct-fired type, meaning that the drying air is in direct contact with the material. Some dryers, however, are of the indirect type, Continue reading →
With the United States oil and gas industry experiencing substantial growth, demand for frac sand has continued to rise; the increasing amount of sand employed per well, combined with longer lateral wells, has caused a surge in demand for the quartz sand unlike anything seen Continue reading →
When it comes to drying bulk solids, rotary dryers are often the industrial drying equipment of choice. Their robust build, reliability, and aptitude for handling variation in feedstock makes them an ideal choice for efficiently drying bulk solids of nearly all types. When referring to Continue reading →
