Application of weighing and batching system

Batching control system：
The design of this automatic batching control system adopts the master-slave structure and connects several single-chip microcomputers to a powerful system, which can be used in the chemical industry, food industry and other batching stations. At the same time, the batching materials can be up to dozens of kinds.

Weighing system automatic batching system:
In the chemical industry, building materials, metallurgy and other industries, a variety of materials are often used for continuous batching, so weightlessness scale is often used.Since the weightlessness scale body is based on the structure of bucket scale, it can directly calibrate the weight. The actual discharge quantity can be calculated by measuring the instantaneous weight of the bucket, and then the closed-loop adjustment can achieve a higher control accuracy, generally speaking, the cumulative accuracy is 0.5%.Because of bucket structure calibration, this system is much easier to maintain than belt scale.

Rate value batching system:
Rate value batching system is not a new concept.As early as in 1987,Liu Duxin, an  engineer in henan Silicate society published Research on the formula of cement raw material in the journal of Henan building materials puts forward the concept of rate value ingredients.In 1991,has published monograph The formula method of rate value of cement raw material batching,Various methods of raw material feedback and callback are discussed in detail. It proved that raw material CaO and Fe2O3 cannot be stabilized when raw material composition fluctuates and further clarified the concept of rate value ingredients.He did not stop at revealing the defects of calcium and iron control, but further studied six callback methods, and put forward the best callback method with qualified guarantee value under calcium and iron control to avoid the defects of calcium and iron control to the greatest extent.The callback method commonly used at present is actually the method advocated by Liu Duxin.Since then, there has been no new breakthrough in the theory of rate-value ingredients.At present, the basic assumption of rate value batching is: to achieve the rate value batching must determine the raw material silicon, iron, aluminum, calcium 4 chemical components.
