Ore dryer operating procedures


Ore dryer Processes:
Dry and wet material is from the belt conveyor or bucket elevator to the hopper, and then is by the hopper feeder feeding through the feeding tube into the side.Slope of the pipe feeding the natural inclination is greater than the material in order to smooth the material into the dryer.Dryer cylinder is into a slightly tilted to the horizontal rotating cylinder. Adding material from the higher end, low-end entry by the heat carrier, and the material into a counter-current contact, but also heat carrier and the material together and flow into the cylinder.With the drum material by gravity, it run to one end than at the end. Wet material in the cylinder body to move forward the process, directly or indirectly to the body containing the hot heat, the wet material to dry, then the discharge end by the belt conveyor or screw conveyor sent.In the cylinder wall with the body copy board, its role is to copy the material up and planted, so that the surface of the material increases the contact with the air flow to improve drying rate and to promote material progress.Heat-carrier is generally divided into hot air, flue gas. After the heat-carrier by the dryer, the general need within the cyclone brought the material to trap the gas down.To further reduce exhaust gas dust content, but also through the bag filter or wet dust collector and then put emissions. Incorporation of material drying sticky paste approach to materials or materials with higher water content. Ore dryer advantage of large capacity, wide range of applications, flow resistance, allowing a larger range operation and easy operation.
