Abstract

Concrete is one of the most widely used materials in the construction projects, the economic and technical index, which is important for the construction project quality and cost of a relationship. The commodity concrete designed according to concrete products with an annual output of 600000 side of the scale of the mixing station, it introduces the concrete mix design, material balance calculation, water supply and drainage system, site selection, production process, equipment selection and calculation of concrete mixing station, and economic evaluation. The station layout drawing process design flow chart, the general layout of the station and each equipment connection.

Keywords: commercial concrete mixing plant； mixture ratio design,；equipment type selection
