What is a Concrete Mixer?

A concrete mixer is a powered device that mixes cement with water and aggregate, such as sand or pea gravel, to make concrete. Concrete mixers range from the very large commercial mixing truck to the smaller, portable concrete mixer sometimes called a “mini mixer”. A concrete mixer is comprised primarily of a motor, a rotating drum, and often a chute. Inside the drum, the materials used to make concrete spin around, mixing together evenly and remaining soft for application and forming. A large commercial concrete mixer truck is used for mixing and transporting large volumes of concrete for use on a building site. For smaller volumes of concrete, typically up to two cubic yards (1.83 cubic meters), a portable concrete mixer is sufficient. A portable concrete mixer is typically powered by electricity and sits on a base with wheels for easier transport. The rotating drum can be tilted down so that mixed concrete can be poured into a wheelbarrow. For homeowners attempting small concrete pr ... more

A concrete mixer is a device that homogeneously combines concrete, aggregate such as sand or gravel, and water to form concrete - a powered device that mixes concrete with water and aggregate, such as sand or pea gravel, to make concrete. Concrete mixers range from the very large commercial mixing truck to the smaller, portable concrete mixer sometimes called a mini mixer. A concrete mixer is comprised primarily of a motor, a rotating drum, and often a chute. Inside the drum, the materials used to make concrete spin around, mixing together evenly and remaining soft for application and forming. Today's market increasingly requires consistent homogeneity and short mixing times for the industrial production of ready-mix concrete, and more so for precast/prestressed concrete. This has resulted in new technologies for concrete production. Worldwide, therefore, twin-shaft batch mixers are becoming more important for high-quality concrete production. They introduce very high turbulence into t ... more
