Generally speaking, there are many factors influencing the dryer production, such as the equipment operation, production management and maintenance. Among them, the main factors affecting the dryer production output include heat source selection, wet material type and hot air temperature.
First of all, the choice of heat source. The coal stove has indirect heating and direct heating. Among them, the indirect heating hot air is clean, but the efficiency is low, suitable for dry the material can't be melt in smoke dust. And direct heating are dust pollution and affect the quality of products, but the thermal energy utilization is very full and has high thermal efficiency. It is the priority when the drying material mixed a small amount of smoke and little effect in the quality. At present, there are a lot of dryer manufacturers use oil burner, the hot blast stove has the advantages of simple operation, rapid heating, temperature stability, convenient control and low cost.
Secondly, the wet material types. Usually we will divide the material into three kinds, 1. The capillary porous material. This kind of material moisture, mainly by capillary action and combination in the material, such as sand, silica, activated carbon, biscuit firing ceramics, etc., moisture and material bonding strength is small, tumble dry more easily.2. Colloidal material. This kind of material of water and material combination form of permeability is dominant, such as glue, flour, etc., the material has big viscosity, water and material of the bonding strength is bigger, tumble dry more difficult3. 3. Capillary porous colloid material. This kind of material has above two kinds of material properties, such as peat, clay, wood, fabric, grain, leather and so on. The shape of the material has a great influence on drying, such as particle materials. The bigger particles are difficult to drying than the small particle materials.Henan Hongxing Mining Machinery Co., Ltd is the professional manufacturer of complete sets of mining machinery, for example,stone jaw crusher, wet magnetic separator Welcome all of you to visit our official website.crushing machine: http://www.crusher-machine.com/n215.html
Finally, hot air temperature. Hot air temperature can also be called drying medium temperature. When Hot air temperature is higher, the more heat energy it contains, and at the same time, hot air relative humidity is lower, and the ability of absorbing water is strong. It is helpful to drying and the drying thermal efficiency is also high.
Above three aspects are the main factors affect the efficiency of dryer, of course, it is not to say that only these three questions. It is necessary to get a thorough understanding of the dryer and can really improve the output of the dryer from all aspects of the dryer.
