One of the first concrete mixers<\/a> ever was developed in 1900 by T.L. Smith in\u00a0Milwaukee. The mixer already exhibited the still common basic construction with a tiltable conical drum (as double cone at that time) with blades. On February 9, 1904, the first portable concrete mixer was patented by Richard Bodlaender, an inventor from Breslau, Germany.[<\/span>2]<\/span><\/a><\/sup>\u00a0This concrete mixer was horse-drawn and called ‘Mortar Mixer’. It worked by replacing the front wheels with a large drum that held large paddles for mixing the cement.[<\/span>3]<\/span><\/a><\/sup>1925, at least two mixers, built 25 years ago, were still in use (serial numbers 37 and 82). The\u00a0Smith Mascot<\/i>\u00a0in essence has the same construction of the small mixers used today. In the 1920s, the\u00a0T.L. Smith Company<\/i>\u00a0in Milwaukee built the world’s largest concrete mixers. Mixers of this company were used e.\u00a0g. for the construction of the\u00a0Wilson Dam\u00a0(six 2-yard and two 4-yard mixers, at the time the largest single installation of the largest concrete mixers in the world), the\u00a0first stadium\u00a0of the\u00a0Ohio State University\u00a0and the\u00a0Exchequer Dam.[<\/span>4]<\/span><\/a><\/sup>\u00a0Roscoe Lee was granted a patent in 1934 for his transit concrete mixer design. This design made it possible for new trucks to be turned into concrete mixers by using a crane to put a drum on the back of the truck.[<\/span>3]<\/span><\/a><\/sup>\u00a0It was less expensive than a cement truck dedicated to only carrying cement and allowed the trucks used to continue to be adapted for other things.[<\/span>2]<\/span><\/a><\/sup>\u00a0Concrete mixers have continued to advance. Recently, research detailing a forward simulation model of an energy-saving concrete mixer using hydraulic technology was released based on Matlab\/Simulink technology.[<\/span>5]<\/span><\/a><\/sup><\/p>\n

For smaller jobs, such as residential repairs, renovations, or hobbyist-scale projects, many cubic yards of concrete are usually not required. Bagged cement is readily available in small-batch sizes, and aggregate and water are easily obtained in small quantities for the small work site. To service this small-batch concrete market, many types of small portable concrete mixers are available.<\/p>\n

A typical portable concrete mixer uses a small revolving drum to mix the components. For smaller jobs the concrete made at the construction site has no time lost in transport, giving the workers ample time to use the concrete before it hardens.<\/p>\n

Portable concrete mixers may be powered by gasoline engines, although it is more common that they are powered by electric motors using standard mains current.<\/p>\n

These concrete mixers are further divided based on their loading mechanism. Cement, sand and other aggregates are loaded in a\u00a0hydraulically\u00a0operated hopper and then poured into the mixing drum for final mixing. They can be unloaded by tilting the drum. In hand-feed concrete mixers, cement, sand and other aggregates are directly added to the mixing drum manually. Both of these types of concrete mixers are popular in construction activities in Africa, some Middle Eastern countries and in the Indian subcontinent.<\/p>\n
