The concrete mixer drum is one of the most important components of a concrete mixer machine. It is responsible for uniformly mixing and preparing concrete and mortar. Through continuous rotation, the drum properly combines the raw materials of concrete and improves the quality of the mixing process.

The concrete mixer drum is usually made of steel and must have suitable resistance to pressure, impact, and wear caused by sand and aggregates. Therefore, the sheet material, drum thickness, welding quality, and internal blades are important factors affecting its service life.
