A cement mixer is required in the construction of buildings as an important piece of equipment. This instrument is also called a concrete aggregator/mixer. The name of this instrument has been derived by its work nature. As, this mixer is used for the aggregation of gravel and water to make a reliable product, known as concrete.

The usual composition of all the mixers are basically the same. A typical concrete mixer will have a drum as a main part. This drum revolves continuously at set speed to bring about the aggregation of ingredients in order to formulate the final product.

More advanced and huge mixers are used when the quantities of concrete are also in larger volumes. However, for considerably low quantities more precise methods and simple means may also be used for this purpose. The concrete mixers make the concrete available at demand by the workers.

A more primitive way of mixing concrete is by hand in a wheelbarrow, which can be termed as a crude form of cement mixer. There are many varieties of concrete mixing machines available in the market. All of them have their unique features and offer various functionalities as well. The original concrete mixer was made by Gebhardt Jaegar who was a Columbian Industrialist.

The construction industry and builders have increased the demand rate for the concrete mixers. These mixers fulfills the requirement of consistent concrete mixing for the workers. They also consume less time when compared to various other methods of concrete mixing. They have also been very useful in the times of ready-mix or pre-cast or pre-stressed concrete demand.

The industrial concrete aggregator has been an equipment that revolutionized the cement market and increased its production to match the growing demand rate. There are diverse mixer types available in the market. These usually target different sections of the market according to the demand. However, there are few very common varieties as well.

The common types of cement mixer can be placed in 3 major categories. The first type is a vertical mixer that is also known by the name of Pan & Planetary mixer. The second type is called a twin shaft mixer. The third one is known as a drum mixer that is also known by the names of Tilting Drum or Reversing Drum. Twin shaft mixers are used for high quality cement mixing. They consume very less amount of time. The concrete produced is also high in strength and durability. The usual batch size is 2-6 cubic meters for this type.

The vertical concrete mixer is another type that is utilized for the manufacture of pre-stressed concrete. This mixer also clearly cleans in between the batches. This is a preferred mixer type when the workers require colored concrete, multiple discharge points and small amounts of concrete (normally 0.75-3 cubic meters). The drum mixer is used for large volumes of concrete production (with average batch size of 3-9 cubic meters).

The varieties of cement mixer have their unique application and usability in the ever-growing concrete industry. The concrete is nowadays produced with improved standards of quality and in less time with these advanced mixing techniques.
