The exciter is posed of eccentric blocks, spindles, bearings and housings. Most of China's vibrating screen can only achieve a screening trajectory, can achieve up to two, this time my design is to match the adjustable trajectory exciter design ofa tunable vibratory screening test stand, different Vibration trajectory should have different sieve angle, so the design of the sieve angle is adjustable in the 0~25° adjustment, the test in the same material, the same exciting force, the same sieve angle and different trajectories In the case of material screening efficiency. Or test the same material, the same exciting force, the same movement trajectory and different sieve angle of the case of material screening efficiency of the impact.
