The utility model relates to a front separation system recovering plastic pellets from garbage. An auto-feed bag breaker conveys garbage to a homogeneous distributor through a plate feeder. The homogeneous distributor is connected with a hand sorting table through a first conveyor. The hand sorting table is connected with a roller bag-breaking screen through a second conveyor. The roller bag-breaking screen is connected with a permanent magnet separator through a third conveyor. The permanent magnet separator is connected with a negative pressure winnower through a fourth conveyor. The vacuum winnower is connected with a positive pressure winnower through a fifth conveyor. The positive pressure winnower is connected with a manual separation chamber through a sixth conveyor. A discharge hole of the negative pressure winnower, a discharge hole of the positive pressure winnower and a discharge hole of the manual separation chamber are all connected with a plastics storage chamber through conveyors. The front separation system is scientific and reasonable in structural design, short in garbage separation time, high in processing capacity, convenient for production, highly operable, and effective in separating plastic products for pellet recycling.
