Batch mixer
Naoi of Kobe Steel, Japan, developed a batch mixer, which includes a floating weight that is freely elevatable by hydraulic cylinders in a hopper. The control device sends a stop signal to a direction switching solenoid valve to stop the action of the hydraulic cylinders when the positional detection signal matches the positional set value.
