| Abstract: |
| 5XZ-5 gravity separator was designed,and its elementary structure and working process were introduced,particularly such as the structural design and working principle of vibrating screen deck,driving system,blower fan system,main working parameters and their regulation.Vibrating system was configured inversely with equal inertia designed.Blower fan system employed 5 centrifugal fans fitted on the same axes,equipped with regulating fittings for air regulation.Experiment on wheat seeds was done,and the main technical parameters were tested.Results showed:practical productivity 5.1 t/h,separation ratio 98.8%,cleaning ratio of grass seed 100%,cleanliness 99.6%,breakage ratio 0.06%,cleaning ratio of heavy mishmash 100%,dust concentration 8 mg/m3,and noise 84 dB(A). |
