Automatic batching machine with frequency control of motor speed system,material door switch is controlled by a separate hydraulic unit,hopper with electric hoist,equipped with vibration device for meterial.according to user requirements,make theleft and right symmetrical configuation operation. For the consistence feeding of concrete into mold,feeding machine is the solution.The feeding concrete is done by having mold sits on trolley.The trolley moves inward to insert the concrete injection pipe into the center of the mold.As the trolley moves outward,predetermined volume of concrete is displaced into the mold.The speed of trolley and the volume of the concrete are electrically programmed to ensure high consistency of concrete volume throughout the production process.This will eliminate wastage of concrete
