2, to ensure the material water content is below 0.5%, the dry mixed mortar and slag powder production line product of choice;

3, cylinder self thermal insulation thermal efficiency as high as 70% or more (the traditional single cylinder drying machine thermal efficiency is only 35%), heat efficiency is increased by 35%;

4, the fuel can be adapted to coal, oil and gas, can bake the 20mm block, granular and powdery materials;

5, than the single cylinder drying machine to reduce the area of about 50%, the investment of construction is reduced by about 50%, reduce power consumption by 60%;

6, according to the requirements of users can easily control the final moisture index;

7, air temperature is low, dust removal equipment, long service life;
