Ore production machine sub-system consists of: mixer, add water cleaning device, chute delivery device, the processing device composed of sand and gravel Whey after separation devices, and muddy water. Concrete conveying device after washing, the residual concrete into the chute, the impact of the water under high pressure through the chute into the sand separator, under the effect of the continuous rotation of the separator, the sufficient cleaning of the concrete, while the sand and stone were separation, after the separation of sand, stone facing away from the flow of the material under the action of the guide vanes, and then by raising ceremony the discharge port separator, respectively stacking. Whey after cleaning discharged from the bottom of the separator into the recycling step by step after precipitation or sedimentation tank into the mixing tank for recycling. Into the mixing tank (generally two stirred tank) of Whey To prevent precipitation coagulation, through the action of the agitator, the agitator working for intermittent. In the continuous separation of water mud agitator role, and then transported by high-pressure water pump to the floor, to be produced by stirring metering reuse. The entire control system with manual and automatic control, easy control settings, the entire system is reliable, low failure rate, low maintenance characteristics.
