The cement cooler designed by our company is advanced and of cooling effectiveness, which takes countercurrent heat exchange. And it takes indirect cooling,which has no negative effect on the cement quality. And the cooling water can be used circularly, which meets the demand of environment protection. And the material is fed from the bottom of the equipment and the material is discharged from the top of the equipment, which makes sure that the material can be cooled fully. The cooling water flows naturally along the shell verge, which can achieve countercurrent heat exchange between cooler water and material, and can maintain high heat exchange efficiency. And the device hoists material spirally, which prolongs the cooling period.
