Drying machine principle of work
Dry wet material from the conveyor belt or a bucket elevator to the hopper, and then through the hopper feeder feeding through the feeding pipe into the end. The feeding pipe inclination angle is greater than the natural materials, so that the smooth flow of material within the dryer. Dryer cylinder is a horizontal rotating cylinder slightly into the slope. Material from the higher end of the join, heat carrier by the low-end entry, and materials into countercurrent contact with a heat carrier, and the material together and flow into the cylinder. With the rotating cylinder materials run by gravity to the lower end of. Wet material in the cylinder body to move forward in the process, directly or indirectly by heat carrier to heat, so that the wet material to be dried, and then in the discharge end of the screw conveyor belt machine or send. The inner wall of the barrel body is provided with a copy board, its role is to bring up another copy of materials cast, so that the materials and the contact surface increases airflow, to improve the drying rate and promote material progress. Heat carrier are generally divided into hot air, flue gas. Heat carrier by the dryer, general need within the gas cyclone brought down trapping materials. For further reduction of exhaust gas dust content, but also through the bag dust collector and wet dust emissions after the release |
