Drying Stages of Fote Sludge Drying Machine

According to the changes of drying speed in rotary drum of sludge drying machine, drying process is classified into three stages, respectively named as heating period, constant-rate drying speed and falling-rate drying speed. Known as the NO.1 brand of coal slime dryer, Fote Machinery has done a lot of efforts to improve the performance of every stage.

To realize the heating period, it is dependent on the work of feed screw blades and lifting boards. For materials just fed into the drum, their temperature is quite low. When slime materials contact with the heating medium, surface temperature will continuously rise. Then, water content in slime materials begin to be evaporated.

Slime materials are easy to adhere on the wall of rotary drum, since they are covered with water film on surface. To avoid this phenomenon, you should make these slime materials collide with each other as much as possible. For the falling-rate drying period, it plays the roles of improving the evaporation speed, increasing the surface temperature and accelerating the heat-transfer rate.

After being evaporated during this period, slime materials will have more voids inside. Water content inside can rapidly move to the surface of slime material. Along with the rising temperature, water remains inside will be evaporated. To ensure the drying quality and improving the drying speed, falling-rate drying period is mainly for excluding the adsorbed moisture in slime materials.

Quality oriented, product will be excellent. With the service tenet of being responsible for every procedure, every product and every customer, Fote Machinery can offer the greater discounts for you on website!
