The concrete mixing station(
Concrete Mixing Plant) is mainly composed of 5 major systems, such as the mixing host, material weighing system, material conveying system, material storage system and control system, and other auxiliary facilities. Compared with the aggregate measurement in the station, the building aggregate measurement reduces four intermediate links, and the vertical cutting measurement saves the measurement time, so the production efficiency is greatly improved.
The concrete mixing station is a combined device used to centrally mix concrete, also known as a concrete prefabrication yard. Due to its high degree of mechanization and automation, its productivity is also very high, and it can ensure the quality of concrete and save cement. It is often used in large-scale concrete projects, long construction periods, large-scale construction sites, medium-sized water conservancy, power, bridges and other projects. With the development of municipal construction, mixing stations that use centralized mixing and provide commercial concrete have great advantages, so they have developed rapidly, and created conditions for the promotion of concrete pumping construction and the realization of joint operations of mixing, conveying, and pouring machinery.
The concrete mixing station is divided into four parts: gravel feed, powder (cement, fly ash, expansion agent, etc.) feed, water and admixture feed, transmission mixing and storage. After the mixer control system is powered on, it enters the man-machine dialogue operation interface, and the system performs initialization processing, including formula number, concrete grade, slump, production volume, etc.. According to the weighing, each silo and weighing hopper are tested , Output empty or full signal, prompt the operator to determine whether to start the stirring control program. Start the sand and stone belt motor to feed into the measuring hopper; open the butterfly valve of the fly ash and cement tank, start the screw machine motor to convey the fly ash and cement to the measuring hopper; open the control valve of the water tank and admixture tank to make the water and external The agent flows into the weighing hopper. After the metering meets the set requirements, the metering bucket door is opened, and the ingredients enter the started mixer to mix and mix. When the set time is opened, the mixer door is opened, and the concrete enters the mixer that has received the material.
