HMK14-DZ standard sieve shaker uses an eccentric weight mounted on upper and lower ends of electric motor shaft to transform the motor rotary motion into three elementary motions (horizontal, vertical, inclined). After that it passes the motion to screen surface. Professional shaking makes the materials tumble, rotate and jump at the same time. HMK14-DZ works with standard test sieves to measure the particle size distribution of granular or powdery materials. It can also be used to determine the solid or impurities content in liquid.
