Analysis of the Working Features of Rotary Drum Dryer

Henan Fote Machinery does some analysis for you:By the hot air flow rate by the heat and mass transfer theory shows that to improve the flow rate of dry air, directly improving the heat transfer coefficient and mass transfer coefficients, drying rate increases, but also the timely replacement of the hot air, conducive to the proliferation of outside process. However, the improvement of the hot air flow rate for a certain length of the rotary dryer, will reduce the residence time of hot air in the drying of the barrel body that may affect the thermal efficiency, resulting in a waste of heat. By increasing the material and the hot air in the cylinder axial unit length of contact time and contact area, through the transformation of the lifting plate materials in the cylinder cross-sectional dispersion of purpose, by increasing the dryer cylinder length.In general, the higher the temperature of the hot air temperature of hot air, heat transfer rate and mass transfer rates higher, in the case of the same amount of water evaporation, the amount of hot air can be reduced, the exhaust heat loss is reduced. However, control of most of the imports of cement plant dryer hot air temperature is low, even if the downstream dryer temperature of 700 ℃ or so, so the extent permitted by the cylinder, the substantial increase in imports of hot air the temperature is not feasible.Scientific management, advanced processing technology and innovative manufacturing theory make Fote Heavy Machinery become the exporting base of poultry manure dryer, lignite rotary dryer and famous grinding equipment in China. What Hongxing has done is for the clients and we believe that quality is the best way to develop market.Third. Into the feed size and feed uniformity in the drying rate in certain circumstances, the material and the hot air the greater the contact area, total dry the better. The smaller the particle size, the internal diffusion resistance of the smaller, help to improve the drying...
