If the gap is excessive, it is necessary to modify the position surrounding the blade in order to attain the precise PMI range. Please ensure to clean the blade and drum of the concrete mixer as soon as it has finished being used. Avoid shocking the electrical components of the concrete mixer by preventing them from coming into contact with water, extreme temperatures, and dust. The concrete mixer technique of applications should be simplified in order to get a greater level of work efficiency.
