The bed surface angle is adjusted by hanging wire rope. In addition, the excitation
force of vibrating motor is adjusted by changing the eccentric block angle to each
other. According to coal nature of fitting raw coal, flexibly adjusting working
parameters of the whole dry separator to better meet the requirements of different
separating target. This equipment have simple structure and has low processing &
operating costs, convenient installation.

4.5.2 Complete set of FX series dry coal washing machine
1) Technical features
FX dry coal separator is mainly composed of the rotating frame, separation bed, and
driving device. Separation bed's horizontal & vertical Angle can be adjusted
conveniently. In addition, the vibrating direction angle of driving device, the casting
angle of feeding end and block angle of coal reject discharge can also be adjusted
easily. According to coal property of feeding raw coal, working parameters of the whole
8/12/2019 Tangshan Branch of CCTEG
49/51
dry separator can be flexibly adjusted to better meet the requirements of different
separating target.
This series of dry separating equipment have larger production capacity that FGX
series. Middling coal & coal reject stay on the separation bed for a longer time and
separation efficiency is thus improved. The raw coal feeding size range is wider, which
is 120-0 mm. When fine coal is less than 15-20% of raw feeding coal, the raw can be
fed into FX separator without pre clarification. The system process is thus simplified. In
addition, the separator has strong adaptability to the raw coal and when the external
moisture is 9-11%, it can also separate effectively.
