Mining Rotary Dryer Introduction:

Mining rotary dryer is also called rotary dryer. It is widely used in building materials, metallurgy, chemical industry, cement industry drying slag limestone, pulverized coal, slag, clay and other materials. The Mining rotary dryer is mainly composed of rotary body, lifting plate, transmission device, supporting device and sealing ring. It has the advantages of reasonable structure, excellent manufacture, high output, low energy consumption and convenient operation. After the wet material is feed into the dryer, the material is evenly distributed and dispersed in the dryer, and fully in contact with the hot air (counter current), which speeds up the drying heat transfer and mass transfer. In the drying process, the material under the action of the inclined plate and the hot air, can be controlled to move as to the finished product of another star-shaped discharge valve of the dryer, which is suitable for chemical engineering. Mining, metallurgy and other industries large particles, specific gravity Large material drying, such as ore, blast furnace slag, coal, metal powder, phosphate fertilizer, ammonium sulfate. Drying of powdery and granular materials with special requirements. Such as: HP foaming agent, lees residue, light calcium carbonate, activated clay, magnetic powder, graphite, pharmaceutical residue. Require low temperature drying, and need a large number of continuous drying materials.

Working Principle:

The slag is delivered to the hopper by a belt conveyor or bucket hoist, and then through the hopper's feeder to the feeding end. The slope of the feeding pipe should be greater than the natural inclination of the material so that the material can flow smoothly into the mining rotary dryer. The dryer cylinder is a rotary cylinder slightly inclined to the horizontal line. When the material is added from the higher end, the heat carrier enters from the lower end, which is in contact with the material counter current, and the heat carrier and the material flow together into the cylinder. With the rotation of the cylinder, the material moves to the bottom end by gravity. In the process of moving the wet material forward in the cylinder, the heat carrier is given directly or indirectly, so that the wet material can be dried. Dryness, then at the end of the discharge through the belt or screw conveyor sent out. A plate is installed on the inner wall of the cylinder of a mine dryer, whose function is to copy the material up and down, so as to increase the contact surface between the material and the airflow, so as to increase the drying rate and promote the material advance. Heat carriers are generally divided into hot air, flue gas and so on. After the heat carrier passes through the dryer, the cyclone dust collector is usually required to capture the material carried in the gas. If it is necessary to further reduce the dust content in tail gas, it should also be discharged after passing through a bag dust collector or a wet dust collector.
