[0002] Cement is 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 cement materials such as sand and stone together. There are many types of cement, and common ones include Portland cement, ordinary Portland cement, slag Portland cement, pozzolanic Portland cement, and fly ash Portland cement. After processing the finished cement, it is necessary to screen the finished cement according to the diameter of the cement particles, so as to classify and pack the cement according to its fineness.
