(1) Power motor drives reducer through belt pulley, then reducer
gives driving force to drive roller through coupling. Final, drive
roller acts on driven roller.
(2) When feeding powdery material into two rollers, they begin to
rotate in opposite direction. The pocket hole on each roller will
be filled up.
(3) When two rollers goes to their contact point, the pressure
reaches peak. Under enormous pressure, the powdery material are
pressed into finished briquettes.
(4) These fresh finished briquettes are conveyed by discharge belt,
and deliver to next process. The leftover powdery will be returned
back for remould.
