From foods to minerals, a variety of industries use industrial coolers to cool bulk solids for subsequent handling, storage, or transportation. When selecting industrial cooling equipment, the choice often comes down to a rotary cooler or a fluid bed cooler. In general, rotary coolers Continue reading →
Cycling and chemical incompatibility are the two main causes of refractory failure in a rotary kiln. Cycling Cycling is the heating up and cooling down of a rotary kiln, and it is the largest source of refractory failure. Refractory expands with the kiln as it 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 →
Refractory, or the lining utilized on the interior of rotary kilns, is a critical component in ensuring process efficiency and prolonging the life of a rotary kiln. Here, we’ll discuss everything you need to know about refractory, including how it works, the different types, and 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 →
