Then, in the operation process of fully automatic concrete mixing plant, water and additives are weighed by electric scale. All needed concrete materials are weighed by electric scale and made a ratio according to design process. The main concrete mixer is adjusted according the materials. When production combination starts and the materials are mixed evenly, computer can send out signals to main console, the materials are discharged by discharging gate opened by cylinder. The concrete gets into the concrete mixing plant directly JS series concrete mixer, which means the production process is finished. All the processes are finished by one person in computer control room.Henan Daswell Machinery is a professional manufacturer of construction machine for almost 30 years in China. We are dedicated to supplying our customers with best service and products, our major products include:WAM Discharging Butterfly Valve,concrete mixing machine,If you are interested in our products, please contact us freely: sales@daswell.com The so-called full automation of concrete mixing plant means that all devices such as transporting system, batching system, mixing system and discharging system can be controlled by a computer. First of all, aggregate concrete batching is transported by belt conveyor. The pump and fly ash are transmitted by screw conveyor to be weighed. Fully automatic concrete mixing plant well reduces labor amount in construction project, and more humanized designs are added in terms of using this kind of concrete mixing plant. Then Cement Screw Conveyors, how do we rightly operate fully automatic concrete mixing plant? Which requirements should be met for operators?
