Metering System of Concrete Mixing Plant

In the concrete mixing station, if the concrete mixer is the "heart" of the mixing station, then the metering system is the "soul" of the concrete mixing plant. Because the metering system directly affects the performance and quality of concrete.

Concrete mixing station metering system is generally reflected in the water, cement, external additives and aggregate on the measurement. The accuracy and stability of the metering system determines the quality of concrete production. Static accuracy can not meet the requirements, the key lies in the accuracy of dynamic measurement of the gap and the computer to capture the data.

In the concrete mixing plant production process, in strict accordance with the ratio of production, there is no written test laboratory personnel instructions, any person is not allowed to increase or decrease raw materials, admixtures and water consumption. Mixing time as the concrete state, without the consent of the test personnel shall not increase or decrease. Production, should closely observe the measurement is accurate, more than the required error should be adjusted in time gap. All dosing should be in the minimum range at no load. Metering system, other anomalies must be promptly reported to deal with.

In addition, the cement, additives, water error can not exceed ± 1%, found that cement, admixture quality is not enough, it should be timely to find the screw conveyor is blocked, and promptly excluded, aggregate error can not exceed ± 2%, when the error exceeds Should be promptly find out the reasons and manual compensation and records.
