Concrete batching plant weighing methods

In the process of production, aggregate, cement, water and admixtures can have its own separate weighing according to their species and size of aggregates are set independently of the weighing device, this weighing method is called a single weighing method. While weighing method alone has high precision, but too difficult to weigh hopper arrangement, so that the concrete batching plant weighing device structure is complex, because the current concrete batching plant tend to aggregate into two groups, but also that were set two sets of coarse aggregate and fine aggregate weighing device. This cumulative weighing method has been generally adopted. Cement is also used cumulative weighing method. Admixtures are cumulative weighing method should not be used in order to avoid chemical changes, so admixtures generally set two weighing device.
One of concrete batching plant weighing methods is using a cumulative weighing method, this method is used in a combined weighing device, which is composed of a cement weighing scales and a combination of sand accumulation. Cement scales in the middle, gravel weighing bucket bag on both sides. In concrete batching plant weighing lever systems, cement and gravel are separate, each individually weighed and cumulative weighing. Cement weighing hopper and gravel weigh hopper has its own discharge gates. 
When thedischarge gates open, the cement was wrapping and unloading gravel concrete batching plant during which the wrapping process, in fact, equivalent to a stirring, mixing efficiency can be improved. This combined weighing device itself also plays a role in collection hopper, weighing layer thus also reduce the height, so the twin-shaft concrete mixer and other construction equipment applications is very abundant.
