The present invention relates to a rotary press filter test apparatus, a measuring method thereof, and a rotary press filter design method. The testing device of the rotary pressure filter according to the present invention includes a pressure regulating tank, a buffer tank, a filtration frame, a liquid storage tank, an electronic balance, and a stopwatch.The buffer tank is connected to the pressure regulating tank, and the filtration frame is , Provided below and connected to the buffer tank, the liquid storage tank is provided below the filtration frame, and the electronic balance is provided at the bottom of the liquid storage tank. In the measurement method of the present invention, a fixed amount of test slurry is supplied to a filtration frame, a gas at a constant pressure is fed to a pressure regulating tank and supplied to the filtration frame through a buffer tank, and a valve at the bottom of the filtration frame is opened to perform filtration. The amount of mother liquor discharged from the frame is measured, and the time of the filtration process is measured. The filtered filter cake and mother liquor are sampled and analyzed according to actual demand, and the washing and drying processes are sequentially performed. You. ADVANTAGE OF THE INVENTION According to this invention, while measuring cost is reduced significantly, more accurate simulation of an actual operation situation is carried out, and accurate and reliable design data is obtained.
