With the development of science and technology, people have also made great efforts in mechanical equipment, in order to make their life more convenient. Before people used natural conditions in drying materials, the drying efficiency was not High, and the drying effect is not good, so people have developed the dryer equipment, in the dryer equipment series small and medium drum dryer equipment is more popular with the majority of users, mainly because it is drying A wider range of applications.
In the general small tumble dryer equipment system, the hot air furnace is used for heating, and the higher temperature when the flue gas enters the drying cylinder is about 650 degrees or higher.
However, the drying of the granular blast furnace slag may cause the granular blast furnace slag to recrystallize and lose its hydraulic activity when the flue gas temperature is close to 700 degrees. Therefore, in the drying process of materials, the required drying temperature should be determined according to the water content and physical properties of different materials, otherwise the physical properties will be changed, which will affect the ingredients of the raw materials and the quality of the cement.
When the temperature of the hot blast stove flue gas is too high, it can be properly mixed with cold air to regulate the temperature drop. A special mixing chamber cold air throttle valve is often arranged between the combustion chamber and the small drum dryer equipment to realize the adjustment and control of the flue gas temperature of the small drum dryer equipment.
The small tumble dryer equipment also uses the hot exhaust gas of the kiln tail preheater and the grate cooler as a heat source, and can be combined with a dust removal facility. Although the system is complex, it saves fuel costs and saves an investment in a dust removal system. However, when the kiln head and the kiln exhaust gas are used to dry the material, the temperature of the exhaust gas is low, the heat is less, and the moisture that can be dried is low.
In order to prevent the water vapor contained in the exhaust gas from condensing in the system, the temperature of the exhaust gas of the small drum dryer equipment should be controlled at 120 to 125 degrees.
Because the temperature of the exhaust gas is low, the natural exhaust of the chimney is not enough to overcome the fluid resistance of the small tumble dryer equipment and the dust removal equipment. The boiler induced draft fan is often used as the full pressure of the fan used for the power of the small tumble dryer equipment, generally 2.5~4kpa.
The heat source of the small tumble dryer equipment, if you can choose more suitable not only can ensure the drying efficiency of the small tumble dryer equipment, but also save resources, Heying Machinery recommends that the majority of users choose the small tumble dryer equipment At the time, we must consult in many aspects, not blindly follow the trend, but also choose the appropriate small tumble dryer equipment to dry the materials.
