Hefei City, building materials supply and marketing company commercial concrete mixing plant technical transformation, the Ministry of Construction projects funded construction in Anhui Province in a larger technological transformation. Conducted a comprehensive market research before the transformation, analyzed and compared various technologies used in the control of commercial concrete mixing plants both at home and abroad, absorbed the experience of transformation in Changzhou and the German technology according to the actual situation of the unit, and compiled a detailed Feasibility study report, developed a specific transformation programs and measures. Only a very short period of time to make the new station with an annual output of 100,000 cubic meters of more than the specifications of the commodity concrete. After one month’s trial production, the control of automation, stability, reliability, weighing speed, metering accuracy, concrete workability, slump and concrete strength are satisfactory and meet the current needs of commercial concrete production . Now the control
