Automatic Control Increases Profits of Concrete Plant
The main function of concrete plant control system is centralized control of the whole concrete batch plant, so control system is directly related to the performance of a concrete mixing plant.
Control system is of critical importance to a concrete batch plant. Just like the human brain to a man, control system plays an important role in a plant of concrete batching.
There are several control methods for users to choose, manual, semi automatic and full automatic control. Full automatic control makes it much easier and more convenient to control a concrete batch plant. Therefore, Modern concrete batch plants often adopt full automatic control.
The main components of an automatic control system include the following aspects: computer, load cell, control cabinet, monitoring system, color display and printer, etc.
PC+PLC control is usually adopted in full automatic control system, which has high reliability. Full automatic control operates based on windows system; it can display the whole production process on a screen vividly in real time. Production perimeters data can be saved in the computer and production statistics report daily, monthly, and yearly can be printed. What’s more, in emergency situations, semi automatic control and manual control also can be used. Therefore, full automatic control is highly reliable.
The appearance of automatic control reduces the risk for a concrete batch plant to produce a bad batch. Because bad batches are usually resulted from material flow problems, if a concrete batch plant adopts automatic control system, the whole production process will be controlled more precisely. In addition, the PLC interface can display the whole production process on the screen in real time, which can ensure the concrete plant operators control the production process better. By checking the screen, a concrete plant operator will get an overview of the whole production process, therefore he can control the whole production easier.
