Concrete central mix plant, also known as centralized concrete mixing plant, is a kind of joint device specialized in centralized mixing of concrete. Central mix plant mainly consists of a mixing mainframe, material weighing system, material conveying system, material storage system, control system and other ancillary facilities. This kind of central mixing plant equipment is capable of realizing the mass production of concrete, thus improving the construction efficiency, reducing the cost, and ensuring the stable quality of concrete.

In the central mix plant, cement is used as the cementing material, and fly ash, cement, large sand and some powder and fine materials are weighed through the batching machine according to the proportional test. After weighing, the operator will start the sand and stone belt motors to send the weighed ingredients to the metering hopper, and then additives and water are added to mix them in the concrete mixer until the desired mixing effect is achieved. After that, the ingredients will be fed into the opened concrete tanker and transported out.

It should be noted that, in order to ensure the quality of concrete,in the working process of concrete batching plant, each cylinder, control valves and motors should be strictly in accordance with the steps of the mixing process, and the operation process must ensure accurate, reliable and stable. At the same time, the central mixing plant also needs to have automatic and manual two working modes, and these two modes need to keep each other constrained and independent. In addition, the system also needs to set the alarm self-protection function, anti-interference function, and the use of computer communication system to set the working status of the concrete mixing plant, fault alarms, etc., in order to real-time understanding of the operating conditions, and in the event of a problem in a timely manner to deal with, to reduce the loss of the enterprise.

Central mix concrete plant is widely used in railroads, highways, bridges, airports, tunnels, hydropower and water conservancy projects, soil industry, mining and civil construction, as well as commercial concrete and concrete products production and other fields. According to different classifications, there are various types of concrete mixing plant, such as according to the structural division, the form of process arrangement, the form of operation, and the scale and so on.

In general, concrete central mix plant is an indispensable and important equipment in the modern construction industry, which provides high-quality concrete materials for all kinds of projects with its high efficiency, stability and reliability.
