Single column hydraulic screen changer for color changing masterbatch manufacturing line

The single column screen changer is designed as an integral cylindrical type, made of high temperature alloy steel, which has excellent performance in high temperature resistance and pressure bearing, and has double filter channels working alternately, which makes screen changing fast and easy for production and maintenance. It has high wear-resistant and high-precision screen design. Under the pressure of 30-50MPa and temperature of 300-400℃, it will not affect its performance. It is designed with lead material exhaust structure, no stopping to change the screen, no leakage of material, no interruption of production, and can ensure the product is not interrupted when changing the screen.
