Product Description Mineral powder, quartz sand, three drum dryer, river sand, sawdust, three return drum dryer, hot air drum dryerThree drumd ryer Usage and application:Three-cylinder three drum dryer equipment can dry dry mortar, yellow sand, cement slag, clay, gangue, mixture, fly ash, gypsum, iron powder and other raw materials, widely used in building materials, chemicals, castings, etc. industry.The three-cylinder dryer improves the internal structure of the original single-barrel dryer, increases the pre-drying of the wet material before entering the machine and prolongs the drying time of the wet material in the machine, plus sealing, heat preservation and reasonable supporting measures to make the dryer dry. Machine production capacity is 48-80% higher than the original single drum dryer.Evaporation intensity per unit volume up to 120-180kg/m3, It has advanced technology, reasonable operating parameters, simple and feasible operation.three pass dryer Working principle:Materials enter the inner side of the drum through the feeding device to realize current flow drying process, and then the materials enter the middle layer of the inner wall through the other end to realize counter current drying process. They are lifted in over and over in the middle layer which advance in two-steps forward and one-step back way. The three-drum dryers absorb heat from both inner drum and middle drum, which extend the drying time and realize the best drying condition. Finally, materials fall into the external layer of the drum from the other end of the middle layer, processing in a rectangle multi-loop way. The dried materials move quickly out of the drum under the hot air, while the wet ones remain because of their own weight. Materials are dried completely inside the rectangle shoveling plate and then cooled by the single drum cooler, thus finishing the whole drying process.Three pass dryer Features1. Low outlet air temperature, longer service life of dust removal equipment.2. Sizes of lump materials, particles, and powders are less than 20mm can be dried.3. Gear driving is not required and it's directly driven by roller, with higher mechanical efficiency.4. Without the phenomenon of air leakage, the sealing difficulty is totally solved, and the installation can be finished within a few hours.5. 50% of area covers has been reduced compared with the single drum dryer, and land investment reduced by 50%, power consumption reduced by 60%.6.The self-insulation thermal efficiency of three-cylinder dryer can reach above 70% (the self-insulation thermal efficiency of traditional single drum dryer is only 35%), it has remarkable energy saving effect.7. Final moisture indicators can be regulated easily according to the request.8. Less than 1% of material moisture can be assured by the three-cylinder dryer, which is the preferred product for the dry mixed mortar and slag powder production line.9.The temperature of discharged material is < 50 oC, which can be directly conveyed into the storage silo, needless to cool down in the cooling shed.Three pass dryer technical specifications :Project Unitφ2.0×6mφ2.5×6.5mφ2.7×7mφ3×7mφ3.2×7mφ3.6×8mφ4.2×8.5mOuter Tube Diameter (m)2.02.52.733.23.64.2Outer Tube Length (m)66.577788.5Cylinder Volume (m3)18.8431.8940.549.4656.2681.38118Rotating Speed (rpm)3-103-103-103-103-103-103-10Material Staying Time(min)12-3012-3012-3012-3012-3012-3012-30Intial Moistue (%)6-256-256-256-256-256-256-25Final Moisture (%)≤1≤1≤1≤1≤1≤1≤1Max Inlet Temperature (oC)750-900oC750-900oC750-900oC750-900oC750-900oC750-900oC750-900oCCapacity (T/H)Slag20-2525-3030-3535-1040-4550-6570-85 Coal Ash10-1717-2120-2523-2725-3030-4545-63 Yellow Sand20-2725-4027-4530-4535-5055-7575-99Model of MotorYr160m-4Yr132m-4EYr160m-4Yr160m-4Yr132m-5EYr160m-4EYr160m-4EMotor Power (kw)7.5×211×27.5×47.5×411×415×418.5×4Model of ReducerXWD-6XWD-6XWD-6XWD-6XWD-6XWD-8XWD-8Speed Ratio of Reducer (I)17-2917-2917-2917-2917-2917-2917-29Weight (T)25323538435777Three pass dryer installation site :Our advantages:1.Good raw materialsDomestic high quality raw materials are used on key components, and the motors are made by famous domestic manufacturers.2.High environmental protectionThe multi-stage dust removal method is adopted, and the exhaust gas is cleanly discharged, which fully meets the requirements of national environmental protection standards.3.Low energy consumptionReasonable operating parameters are selected for the dryer in our factory. The coal consumption and electricity consumption are reduced by 20-30% compared with the general dryer.4.Less wearing partsBoth the idler and the ring gear are modern heat treatment processes with a replacement cycle of 5000 hours.5.Full automationThe whole production process only needs one person to supervise, and the finished products are packaged and stored directly.6.High production capacityThe output increased by more than 20%, which has been widely used in cement and mineral processing enterprises.
