How to Make Materials Weighing of HZS90 Concrete Batching Plant
The material weighing directly affects the weighing accuracy of the HZS90 concrete batching plant, which is related to the normal operation of the batch plant. Only the weighing accuracy of each material can ensure the quality of concrete production.
The materials weighing of HZS90 concrete batching plant include aggregate weighing,powder and liquid weighing, directly affect the quality of concrete and concrete production cost.
First of all, the HZS90 concrete batching plant mostly use various materials independent weighing way, namely aggregate, cement, water and liquid admixture are individually weighing, all weighing is electronic scale and microcomputer control. The weighing accuracy is less than 2%, cement, powder, water and additive weighing accuracy reached less than 1%.
Secondly, concretely speaking, weighing the aggregate is an independent weighing device separately based on its varieties and particle size. This weighing method is called the separate weighing method. The individual weighing method has the advantages of high weighing precision, but it is difficult to arrange the weighing hopper because of too many weighing hopper, which makes the structure of the weighing device of the batching plant too complex. At present, HZS90 concrete batching plant generally divide aggregate into two groups when aggregate is weighed, and two groups of weighing devices are set up respectively, coarse aggregate and fine aggregate. This cumulative weighing method is widely applied.
For cement and water using cumulative weighing method, and liquid admixture is unfavorable use cumulative weighing method, lest cause chemical changes, so the general set up two weighing device.
