Drying Engineering Introduction from ngacrusher's blog

For a long time, the Artificial Sand Making Process Project utilized in numerous industries in our state has adopted L-shaped lifting board framework, as well as dryer machine is often from the point out of low performing efficiency: lower output, substantial coal intake, small heat efficiency, superior h2o material on the discharged materials and problems from the charge of h2o articles. The elements influencing the drying process of rotary dryers is often classified into two sorts: a person is definitely the elements due to the rotary dryer by itself, including the lifting board, the rotation speed of the drying device as well as the warmth insulation on the dryer cylinder and the other just one will be the drying technology, which includes the flow speed in the air, the temperature in the warm air, incredibly hot blast heater, feeding granularity and the uniformity with the product feeding, the structure and house in the resources as well as operation on the drying products. Dryer equipment can be a principal energy-consuming device to make sure that we must always test our greatest for making it attain higher good quality, substantial output and low vitality usage. In this article We're going to chat with regards to the elements influencing the drying outcome. The flow velocity of warm air From your heat transfer and mass transfer principle, we could know that bettering the movement velocity of dry air will instantly enhance the warmth transfer coefficient and mass transfer coefficient. Rising the drying velocity can well timed change the scorching air, and that is conducive to your external diffusion method. The temperature of hot air The higher the temperature of warm air is, the higher the rate of warmth transfer and mass transfer are going to be; and over the ailment in the exact moisture evaporation capacity, the quantity of sizzling air is often reduced, which will lessen the squander air warm decline. However, at present the temperature with the inlet very hot air with the dryer equipment utilized in several cement vegetation may be very very low, and also the temperature of downstream drying devices is only about 700℃, for this reason, in the permitted selection in the cylinder, tremendously bettering the inlet temperature of the hot air is not practicable.
