Three Return DryerThree Return Dryer

Introduction:
Three return dryer with the latest European energy saving technology, Mosaic structure, dryer is one of the new energy-saving drying equipment. Master cylinder is made up of three cones interlocking, stagger the direction of each cylinder distance welded together. Itself to form a thermal insulation structure. Special thermal design ideas, elimination of wind tunnel heat loss, increase the heat exchange area and the unit of solvent evaporation strength, good energy saving effect. Conforms to the international to create environment-friendly, resource conservation-oriented society policy, is instead of the traditional drying equipment environmental protection energy-saving products.
 
Working principle:
Wet material by feeder continuous evenly to the inner barrel, through the helical feed plate scatters and move forward, the other by the middle break up device, scattered into act and good contact with heat. Steam water quickly formed by the induced draft fan leads. Almost done materials enter the cylinder, outer barrel. Sufficient heat to contact again after the drying requirements into the bin.


Performance characteristics:
1. Investment in equipment is imported products 20%, with wear-resistant manganese plate manufacturing, than ordinary steel wear-resistant 3-4 times;
2. The material initial moisture 15%, final moisture to ensure the following 0.5-1%, cement plant is the preferred product of slag powder, dry mortar production line and other various drying engineering;
3. Than the traditional single cylinder drying machine to improve the thermal efficiency of more than 40%;
4. The fuel can be used anthracite, bituminous coal, coal gangue, oil, steam, can bake 20-40mm block, granular, powdery materials;
5. Than the single cylinder drying machine cut around the area of 60%, construction investment is reduced by about 60%, convenient installation;
6. No leakage phenomenon, completely solves the sealing problem;
7. The material temperature below 60 degrees, can be directly into the database, without the need for cooling roof cooling;
8. The outer cylinder body temperature below 60 degrees, the exhaust gas temperature < 120 degrees, dust removal equipment bag used for a long time more than 2 times;
The three return dryer equipment coal consumption is single cylinder drying machine 1/3, saving 40% tons of standard coal consumption, < 9 kg.
