The installation and maintenance of mixing blades can be done well from the following angles.
One is idling before work：
Before each shift, the mixer should be idling for two to three minutes to check whether the mixing blades are firm and normal. And when idling, relevant maintenance personnel and construction personnel should stay away from the exit direction of the mixer as much as possible to avoid casualties caused by parts flying out.
The second is the control of material selection：
For concrete materials, screening should be carried out before they are put into mixing, including inspections of small problems such as formula material specifications, material properties, and pH, so as to avoid unnecessary corrosion of concrete blades due to improper materials.
The third is listening at work：
During the whole mixing process, pay close attention to the sound, speed and running force of the mixer blades to prevent accidents such as breakage.
Fourth, cleaning after work：
After each mixing is completed, the blades of the concrete mixer must be cleaned to remove the dirt on the blades; secondly, lubricating oil is often added between the bearings and blades of the mixer, between the blades and the handles of the mixer, especially for the blades of the mixer. Rust removal and rust removal treatment to avoid rust and corrosion of blades due to improper maintenance.
Fifth, regular inspection：
The wear of the concrete mixer blades should be checked regularly to increase the wear resistance of the blades. Once an abnormality is found, it should be dealt with in time and recorded well.
