After adding water and stirring, it becomes a slurry, which can harden in the air or in water, and can firmly cement materials such as sand and stone together. The early mixture of lime and volcanic ash is very similar to modern lime volcanic ash cement. It is used to cement concrete made of crushed stone. After hardening, it not only has high strength, but also can resist the erosion of fresh water or salt water. For a long time, it has been widely used in civil engineering, water conservancy, national defense and other projects as an important cementitious material. In the cement production process, it is often necessary to use a cooling device to cool the cement clinker.

A storage plate 5 is fixedly installed at the bottom of the door-shaped main frame 4, and a water tank 7 is fixedly installed on the storage plate 5. An inlet pipe 701 and an outlet pipe 702 are fixedly connected between the water tank 7 and the cavity 201, and a valve 703 is provided on the outlet pipe 702. The capacity of the water tank 7 is much larger than the cavity 201.

When the cement clinker cooling device is used, the clinker enters the insulation barrel 2 through the hopper 1, water circulates between the cavity 201 and the water tank 7, and the water and the cement clinker exchange heat. The fan 10 provided on the discharge pipe 6 further cools the cement clinker to improve the cooling efficiency.
