Concrete mixer which is also commonly named as cement mixer is a device that homogeneously combines cement, aggregate such as sand or gravel, and water to form concrete.

History
Why did man invent concrete mixer? The reason of it is that in the early 20th century, the concrete was developed when some new materials added to cement. After the concrete was developed, the art of mixing it had to reform. Therefore, concrete mixers were becoming pretty popular by early 20th Century. This coincided with increased usage of motorized vehicles. Cement mixers had trays. These trays were heated on simmering coal. A mixture was set to dry in this.

Development
But things were not all hunky-dory. Concrete mixers got caught up in environmental issues in 1970s. A few changes had to be made. Technology of concrete mixers had to be improved to become environment friendly and abreast with the changing times. Now, concrete mixers do not cause noise pollution, are weather-friendly and more efficient. The concrete mixer is better and durable.

With the rapid development of the whole world, more and more concrete was in demand in construction works and other fields of works. In order to cater to the needs of the world, more kinds of concrete mixers were invented. Their application range was also expanded.

Various Concrete Mixers in the Market
Nowadays, according to their working principles and their structures, concrete mixers can be divided into three categories which are JS twin-shaft concrete mixer, MP Pan concrete mixer, and portable concrete mixer (consisted of JZC/JZM concrete mixer and mini concrete mixer). JS twin-shaft concrete mixer also called forced type concrete mixer, mainly depends on the movement of mixing...
