Types of automatic batching system

1, master-slave distributed control microcomputer batching control system

This automatic batching control system is designed to use the master-slave structure, will be more than one single-chip microcomputer connected to form a powerful system, which can be applied to large-scale concrete batching plant, and can batch as many as 9 to 12 kinds of materials at the same time.

2, loss-in-weight automatic batching system

In the chemical industry, building materials, metallurgy and other industries often need to carry out a variety of materials for continuous dosage, so often use loss-in-weight scales. Because the loss-in-weight scale is based on the structure of the bucket scale, it can be calibrated directly with weights, and the actual amount of material discharged can be calculated by testing the weight of each moment of the bucket, and then adjusted in a closed-loop manner, so as to achieve a high control accuracy, generally speaking, the cumulative accuracy is 0.5%. Because of the bucket structure, calibration, maintenance of this system is also much easier than the belt scale.

3, rate value batching system

Rate value batching is not a new concept. As early as 1987, Henan Silicate Institute of Liu Duxin engineers in "Henan Building Materials" published in the "on the cement raw material batching formula research" on the rate of the concept of batching, 1991 also published a monograph "rate of cement raw material batching formula method", a detailed discussion of the raw material feedback back to the adjustment of the various methods to prove that in the fluctuation of raw material composition of raw materials alone to control raw material CaO, Fe2O3 can not stabilize the three rates of value, further clarifying the raw material three rates of value. Raw material three rate value, further clarified the concept of rate value batching. He did not stop at revealing the defects of calcium and iron control, but further studied six kinds of callback methods, and proposed the best callback method to ensure the qualified rate value under calcium and iron control, which maximized the avoidance of the defects of calcium and iron control. The callback method commonly used in cement plants is actually the method advocated by Liu Duxin. Since then, there is no new breakthrough in the theory of rate-value batching. The basic assumption of the current rate of value dosage is: to realize the rate of value dosage must be determined by the birth of material silicon, iron, aluminum, calcium, four kinds of chemical composition.
