Background

Precast slabs of various specifications are required to be used in the prefabricated house building, concrete is required to be used in the production of the precast slabs, and when the concrete is stirred in the stirring tank, the internal sampling is required to measure the proportion of sand, stone and cement. For example, if the concrete is not up to standard, the raw materials need to be added again to ensure the production quality of the concrete. In the traditional process, the emptying and sampling are carried out after the emptying valve at the bottom of the stirring tank is opened.
