Technical Field

[0001] The utility model relates to the technical field of cement production equipment, in particular to a cement production lifting device. Background Technique

[0002] Cement: A powdery hydraulic inorganic binder. After being mixed with water and stirred, it becomes a slurry, which can harden in the air or in water and can firmly bond materials such as sand and stone together. The early mixture of lime and volcanic ash was very similar to modern lime-volcanic ash cement. The concrete made by bonding crushed stones with it not only has high strength after hardening, but also can resist the erosion of fresh water or salt water. For a long time, as an important binder, it has been widely used in civil engineering, water conservancy, national defense and other projects. In the old days, cement was also called "foreign cement".
