First of all, at the end of every day, you must remember to clean up the mixer thoroughly. It is best to clean the mixer at least once during the curing of the concrete to prevent piles of material in the mixing tank. Short-term cleaning during production stops is more effective than cleaning after the end of each shift.
Secondly, when cleaning the concrete mixer, in addition to washing with water, you can also mix it with water and small stones to make it cleaner.
In addition, during manual cleaning, do not use a hammer to remove the solid concrete blocks, in case the action is vigorous and the mixing arm breaks, which is not worth the loss.
