Checking and inspect refactory
Author: dajiaTime: 2016/04/21

Rotary kiln is mainly for calcination in various industries, inner temperature can reach 1200-1400Deg. Only depend on rotary kiln shell, that is bot enough to keep higher temp. Refactory material are used in rotary kiln is mainly for protecting. 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. The working layer is what is in direct contact with the material being processed. Because of this, this working layer is a dense lining that can withstand the high temperatures within the rotary kiln, and the constant abrasion from the material. However, when it comes to refractory, the denser it is, the less insulating capabilities it has. This means that even though there may be a tough, durable, thick working layer in place, the heat can easily pass through it to the shell of the rotary kiln. For this reason, an insulating layer is needed beneath the working layer. The insulating layer does just that; it insulates the shell of the rotary kiln so the high temperatures cannot reach the shell and damage it, or the nearby components.

 

Our customer who purchase rotary kiln from us, but also buying refactory material in here. We take them for inspecting production and check final product qualiy.
