20M Length 1000kg/h Treated Amount Rotary Drum Dryer For Ore Drying
Drum drying equipment is a kind of rotating continuous drying equipment with internal heating conducting-style. Certain thickness of materials film attach to the drum from material liquid vessel under the drum. Heat is transferred to the internal wall of the cylinder through pipes and then to the external wall and to materials film, to evaporate the moisture in materials film so as to dry materials. Dried products are then scraped off by the blade fitted on the surface of the cylinder, fall down to the spiral conveyor under the blade, and are conveyed, collected and packed.
Product Features
1. High heat efficiency. The principle of heat transfer of the cylinder dryer is heat conduction and the conducting direction keeps identical in the whole operation circle. Except heat loss of end cover and radiation loss, all heat can be used for evaporation of wet materials on the wall the cylinder. The efficiency can reach 70-80%.
2. Large operation elasticity and wide application. Various drying factors of the dryer can be adjusted, such as concentration of feeding liquid/thickness of material film, temperature of heating medium, rotating speed of the drum etc. which can change drying speed of the under dryer. As these factors have no interrelations each other, it brings great convenience to dry operation and makes it applicable to dry various materials and to meet different requirements of production.
3. Short drying period. The drying period of materials is normally 10 to 300 seconds, so it is suitable for heat-sensitive materials. It also can be pressure reducing operated if it is put in vacuum vessel.
Product Process Flow
After being fed into the hopper, under the function of gravity the raw material will fall onto the belt conveyor laid under the bottom of the hopper, and then which will be conveyed onto the screening machine, the massive, strip and other irregular material will be separated out after screening, and uniform particles will be conveyed to the feeding end of the dryer (The single cylinder or three cylinder dryer will be chosen as per the service condition) by the belt conveyor under the screening machine. The feeding end of the dryer is connected with heat source and the discharging end is linked with pulse air pipes. The fire wall will be setted up in the hot blast stove in order to guarantee the safety of the drying process, to eliminate the phenomenon of material burning in the dryer, and the heat passing through pipe will be installed between the hot blast stove and the dryer as the section of heat buffer. The material will brought into the diameter-transformed pulse pipe after being dried and the dehydration for the first time inside of the dryer, which will be in a suspended boiling form at the large diameter of the pulse pipe, and then it will be quickly dried after contacting with the exhausted heat wind from dryer. And the material will be driven out of the pulse pipe by strong winds and moved into the first stage cyclone collector when its water content reaches the design requirement, and 80% of dried material will be collected, and then get into the second stage cyclone collector after passing through the induced draft fan to collect the left material. The second stage cyclone collector can be replaced by the bag type dust collector.
