In an article for the Sydney Morning Herald, Melinda Ham outlines a few of the key processes by which waste is recycled and reused throughout Australia. As recycling becomes a necessity rather than a nicety, the importance of turning wastes into value-added products will become …
The refractory in a direct-fired rotary kiln is a crucial component, serving to both protect the shell of the drum and combustion chamber from the high interior temperatures, and to minimize heat loss. As a result, protecting refractory is not only critical to promoting optimal …
When it comes to mining coal, there are two processes by which coal can be removed from the ground: surface mining, or underground mining. In Australia, the majority of coal mining is done via the opencast method, although often the method of choice is dependent …
After a material is chosen for your rotary kiln refractory, you must decide the desired heat loss. When efficiency is of concern, or very high temperatures are involved, often it is desirable to use multiple layers of refractory: a “working” layer, and an insulating layer. …
Refractory is what protects the shell of a direct rotary kiln from the heat within, so as you can imagine, choosing a quality refractory that is right for your material is extremely important in the design of a rotary kiln. Choosing a refractory that will …
The conference, which will be held in Houston, Texas, is the world’s leading sulphur and sulphuric acid annual event. This year, sulphur industry experts will take a look at market intelligence, technical innovations, and regulatory issues. FEECO will be attending CRU’s Sulphur 2011 Conference this …
Holding the appropriate temperature within a rotary kiln is what allows the desired chemical reaction to occur. Sustaining that temperature, however, can be difficult if the right seal is not chosen. Almost all rotary kilns run at a negative pressure, meaning gas doesn’t leak out, …
Rotary kilns are integral to modern industrial processing, providing a controlled means of initiating chemical reactions and phase changes. As they are highly flexible and can be used to process hundreds of different materials, optimizing the performance of a rotary kiln around the process and …
Rotary kilns can be configured to fit nearly any process need, with a variety of customizations available to engineer an optimal processing solution. One customization that helps to promote efficiency in an indirect kiln is the bed disturber. Why use a Bed Disturber Indirect rotary …
Rotary kilns are a highly engineered thermal processing device, capable of carrying out a wide variety of objectives, from catalyst production to metal recovery. While much of the design of a rotary kiln is engineered around the unique characteristics of the material to be processed …
