How to Effectively Reduce the Heat Loss of Gypsum Rotary Kiln?
Gypsum rotary kiln, as its name implies, is the equipment mainly used for calcining gypsum. This equipment is industrial equipment for the preliminary refining of gypsum ores, and it will also increase the output of gypsum ores. The gypsum produced is mainly used in cement regulation, construction, and other fields, so it has no small use value. Therefore, it is necessary to reduce the heat consumption of the entire gypsum rotary kiln to improve the output and quality of calcination. What methods can reduce the heat consumption of the entire kiln body?
First, Spray with thermal insulation materials. Spraying the gypsum rotary kiln is a direct method. The thermal insulation material is generally in the form of a fine powder, and it is in the form of a slurry after adding water. Therefore, the material is made of lightweight hollow micro-beads. Therefore, its thermal insulation effect is good. In addition, when spraying, add some anti-crack fiber shortcut wire, and then spray with a spray gun, which is fast and convenient.
Second, use thermal insulation materials for thermal insulation. Silicon plate material can be used for thermal insulation inside the gypsum rotary kiln. Silicon plate is a new type of material with light, thermal insulation, and fire resistance, and is made of calcium and silicon materials. In addition, it can withstand the continuous high temperature in the kiln. A layer between the refractory brick and the steel plate of the kiln can effectively reduce heat loss.
Third, choose high-quality fuel. When selecting the coal for combustion, it is necessary to select the coal with good quality, good use of heat energy, and less loss, and also ensure that the moisture content and particle size of the coal meet the process requirements of the gypsum rotary kiln.
Fourth, feed accurately and appropriately. When the coal feeding rate is inaccurate, it is mainly due to the inflexible adjustment of the coal feeding system, or the error of the operating staff who can not properly reduce the feeding rate according to the change of the temperature in the kiln, resulting in the loss of heat energy without full combustion. Therefore, when using the rotary kiln equipment, it is necessary to control the coal feeding rate, properly seal all parts, and strengthen management, No air leakage is allowed in the whole kiln body.
