Encyclopedia > Concrete mixer
This portable concrete/mortar mixer has wheels so it can be moved around by hand, and its rotation is powered by mains electricity. The level allows the concrete/mortar to be tipped into a wheelbarrow.

A concrete mixer (sometimes erroneously called a cement mixer) is a device that homogeneously combines cement, aggregate such as sand or gravel, and water to form concrete. A typical concrete mixer uses a revolving drum to mix the components. For smaller volume works portable concrete mixers are often used so that the concrete can be made at the construction site, giving the workers ample time to use the concrete before it hardens.

Industrial mixers

Twin-shaft batch mixers are used for rapid concrete production.

Twin-shaft batch mixers are used for rapid concrete production.

Today for the industrial production of ready-mix concrete or even more precast/prestressed concrete the market requirements for consistent homogeneity and for short mixing time are increasing. This results in new technologies for concrete production. Worldwide twin-shaft batch mixers are therefor getting more and more importance for high-quality concrete production. They introduce very high turbulence into the mix and achieve about 95% homogeneity at only around 30 sec mixing times per batch.

A Concrete Transport belonging to Bard Concrete of Dubuque, Iowa. This truck had just finished unloading a batch of concrete.

Special concrete transport trucks are made to transport ready-mix concrete from a factory/plant to the construction yard. Because of the difficulty in tipping a large drum attached to the back of a concrete truck, the interior of the drum on a concrete truck is fitted with a spiral blade. In one rotational direction, the concrete is pushed deeper into the drum. This is the direction the drum is rotated while the concrete is being transported to the building site. When the drum rotates in the other direction, the Archimedes screw-type arrangement forces the concrete out of the drum, and then optionally onto slides to guide the viscous concrete, or a concrete pumper.

Concrete mixer - Patent 7048429 (2509 words)
In the concrete mixer as set forth in a third aspect, the vibration transmitting means comprises: a pair of arms integrally protruding from the mounting frame; and a rotation member rotatably supported by respective one end of the pair of arms, the rotation members contacting the drum.
The concrete mixer as set forth in a fifth aspect, fixes a drum to a mounting frame and mixes various kinds of materials in the drum while rotating agitating blades provided inside the drum, wherein the drum is equipped with a vibration device.
In the concrete mixer of the seventh aspect, the mixture moves up by the rotation of the agitating blades and falls down due to its weight since the drum and the agitating blades are inclined, while this flow of the mixture agitates the mixture itself.
