Insulation properties lignite dryer drying materials directly affect the quality and the level of energy consumption, so that is also very important, as we all know, lignite is a relatively high water content of the material, so that, if you want to bake good quality dry out, and low power consumption, heat on lignite dryer plays a decisive role. So, what kind of insulation material in the end choose the best? This article will explain in detail.
Initially, the insulating material used is asbestos cloth longer, but it has been substantially eliminated, the asbestos fibers on the human body because there is a certain danger of exposure to the temperature range of glass wool at 300-400 ℃, and lignite dryer in the early drying is still possible, but if at a later stage, the temperature is far more than the 400 ℃, it is not the most appropriate. There is also a mineral wool material, in fact, the production of raw materials is a slag, the cost is very low, but can withstand the temperature is not very satisfactory. And now the most commonly used is rock wool, because it can withstand high temperatures, and the performance is very good, so it is an ideal insulation material, but at the time of installation, it is recommended to use an external lignite dryer layer jacket made of galvanized iron, so you can maximize the insulation, thus greatly improving the drying efficiency and reduce energy consumption. All in all, whether it is good for insulation lignite dryer is very important, and it is important to improve the one hand, many manufacturers.
