As we know, the method of eliminating the cement when cleaning concrete mixer is mainly depended on whether the cement structure is fresh or dry. The fresh concrete is not difficult to eliminate with water and stones for 10 to 15 minutes. If it is necessary to enter into the mixing drum, users must be very careful and cut down the power supply. Then users can knock the mixing drum with rubber hammer until the large cement in the mixing drum is eliminated. If there is still concrete remaining in the concrete mixer, such as hydrochloric acid, and keep the concrete mixer rotating slowly. Make sure there is no water in the mixing drum, especially in the cold winter. Clean the remaining concrete daily and the remaining cement should be fresh and wet, which can prolong the service life of concrete mixer and save resources.
