Cement is made from a combination of crushed limestone, clay and water. It is used in the construction industry because of its relatively low cost and strong, dense properties. In contrast to bricks, which need to be cut to required dimensions and carefully set in place, concrete simply can be mixed in a cement mixer and poured in place. The construction industry uses a range of mixer types to suit specific requirements.
Stationary Cement Mixers
As their name suggests, stationary cement mixers are not designed to be transported from location to location. These cement mixers usually are used for large-scale building projects. where a constant supply of cement is needed with a fixed location. Stationary cement mixers are larger in size than other types, allowing them to mix more concrete for building projects.
Mobile Cement Mixers
Mobile mixers are used to prepare concrete in one location and transport it to another. These cement mixers often are installed on the back of large trucks, where the device mixes concrete in a large metal unit. This kind of mixer often is used to mix cement for sidewalks and road structures, where a steady amount of concrete may need to be spread over a large area.
Electric Cement Mixers
Electric mixers have the advantage of being portable and are relatively inexpensive to purchase or rent. These mixers should be used with caution. As they use electric cables and a power supply, there is a greater risk of accidents during construction work.
Petrol and Diesel Mixers
Petrol and diesel cement mixers typically are more expensive than their electric counterparts, but are less expensive to run on site as they do not require electrical input. These mixers are relatively easy to maintain and are less noisy than other types of mixers.
Vertical Axis Mixers
Vertical axis mixers employ planetary and pan mixing mechanisms, and commonly are used in the creation of a range of concrete, including coloured concrete, pre-stressed and precast concrete. Vertical axis mixers usually have several discharge points built into the main unit, allowing for flexibility in the mixing and spreading of concrete.
Drum cement mixers are employed to create large amounts of concrete in a specific location. These mixes are characterised by swift production speed, particularly when producing slump concrete. Drum mixers require relatively little maintenance when compared to other mixer types, as they use a fairly uncomplicated mixing mechanism.
Twin mixers have dual shafts, making them suited for mixing at high intensities and for producing batches of concrete in short periods. Twin mixers usually are used in the preparation of high-strength concrete used in the construction of large buildings.
