1.The counter-current cooling principle, particles, uniform, cooling fully
2.Unique rotating well material institutions, material distribution, more uniform cooling more thoroughly;
3.The hydraulic system control tilting discharging institutions, recumbent flap discharging uniform, fluent, discharging speed adjustable;
4.Can be suitable for round state, massive, flake, granular and all kinds of materials, particularly suitable for cooling material, puffed material expansion in product materials cooling.
