Since the concrete mixing plants began to develop rapidly in China it has a history of more than 30 years. Today, the mixing plant is very mature either from the production experience or the technical level. But we will find a careful summary, the current new mixing plants is also after several generations of updates to become today's appearance.

At the beginning, the concrete mixer plants was accumulative weighing , the accuracy is not high, the quality of concrete is poor, generally with skip bucket feeding, on-site mixing, without concrete mixer truck conveying. Later on, the mixing plant made an improvement on the measurement, and began to separate the material according to the aggregate, powder, liquid measurement and separate transportation, and the quality of concrete was better. Then people began to consider the environmental protection problem, dust removal systems are installed for collecting the dust emission from powders and aggregates, and the main station has begun to try partial external packing, but the sand and stone is still stacked at open yard, which is also the most common concrete mixing plant on the current market.

The above mentioned concrete mixing plants, in the face of higher and higher engineering quality requirements and in the face of environmental protection problems, or can not meet the development needs of The Times, but also faced with the risk of being eliminated by the new mixing plants.
