The basic working principle of the concrete mobile plant is almost the same as that of the stationary concrete plant. They are mainly composed of 5 major systems such as the concrete mixing host, material weighing system, material conveying system, material storage system, control system, and other auxiliary facilities. What is the basic working principle of the mobile concrete batching plant?
The mobile concrete plant can be divided into 4 parts: sand and gravel feeding, powder feeding, water and admixture feeding, transmission mixing and storage. After the concrete mixer control system is powered on, it enters the man-machine dialogue operation panel, and the system carries out initialization processing, which includes formula number, concrete grade, slump, production volume, etc. Carry out inspections on each silo and measuring hopper according to the weighing, and output the empty or full signal to remind the operator to confirm whether to open the mixing control program of mobile concrete batching plant.
The basic working principle of concrete mobile plant: Open the sand and stone belt motor to feed the material to the metering hopper; open the butterfly valve of the fly ash and cement tank, turn on the screw motor to transport the fly ash and cement to the metering hopper; open the control valve of the water tank and the admixture pool to make the water and the agent flows into the metering hopper. After the metering meets the setting regulations, the door of the metering bucket is opened, the ingredients enter the opened mixer for mixing, and the mixer door is opened at the set time, and the concrete enters the concrete mixer truck that has received the material.
Each cylinder, control valve and motor operate in accordance with the regulations of the concrete mixing process. The control of each cylinder, control valve and motor must be accurate, stable, safe and reliable. The control system has two working modes: automatic and manual, and the relationship between them is independent and restricting each other. The internal system of the concrete mobile plant has good anti-interference ability and perfect self-protection function of alarm signal. By communicating with the computer, it can display the operating status of the system and the fault alarm signal.
