Roller Dryer Mineral Powder Steel Slag Drying Equipment Mortar Mechanism
Working Principle of Roller Dryer
1. The dry wet material is sent to the hopper by a belt conveyor or bucket elevator, and then enters the feeding end through the feeding pipe of the hopper feeder. The inclination of the feeding pipe should be greater than the natural inclination of the material so that the material can flow smoothly into the dryer. The dryer cylinder is a rotating cylinder slightly inclined to the horizontal line. The material is added from the higher end, and the heat carrier enters from the lower end, and contacts with the material in countercurrent. There are also heat carriers and materials that flow into the cylinder together. As the cylinder rotates, the material moves to the lower end under the action of gravity. During the forward movement of the wet material in the cylinder, it directly or indirectly obtains heat from the heat carrier, so that the wet material can be dried, and then sent out at the discharge end through a belt conveyor or a screw conveyor.
2. A shoveling plate is installed on the inner wall of the drum dryer cylinder. Its function is to scoop up and scatter the material, so that the contact surface between the material and the airflow is increased to increase the drying rate and promote the advancement of the material. The heat carrier is generally divided into hot air, flue gas, etc. After the heat carrier passes through the dryer, a cyclone dust collector is generally required to capture the materials in the gas. If the dust content of the tail gas needs to be further reduced, it should also pass through a bag dust collector or a wet dust collector before being discharged.
Performance Characteristics of Roller Dryer
1. Adopting the downstream drying method, hot air and wet materials enter the dryer from the same side, high-temperature air can be used to obtain high evaporation intensity, low dryer outlet temperature and high thermal efficiency;
2. Strong anti-overload ability, large processing capacity, low fuel consumption and low drying cost;
3. Adopting new feeding and discharging devices, it eliminates feeding blockage, discontinuity, unevenness and return of materials, and reduces the load of dust removal system;
4. The operating parameters can be changed according to the properties of different materials, so that the material can form a stable full-section material curtain in the cylinder, and the mass and heat exchange is more sufficient;
5. It realizes "zero horizontal thrust", greatly reduces the wear of the support wheel, and the cylinder runs smoothly and reliably;
6. Adopting "self-aligning support wheel device", the support wheel and the roller ring are always in linear contact, which greatly reduces wear and power loss;
7. The moisture content of the product can be controlled according to user requirements.
