Vertical Lifting Feeder For Hopper Loading & Powder Transfer Station

Built as a self-contained compact processing unit, the

all-in-one vacuum conveying classifier

integrates vacuum pneumatic feeding, temporary material buffering, precision particle grading and height fine-adjustment into a single streamlined system, eliminating the inefficiencies of fragmented multi-stage material handling workflows. During routine production runs, its built-in vacuum generation unit creates consistent negative pressure airflow to draw powdered and granular raw materials directly from fluidized bed processing equipment. All materials travel through fully hermetic pipelines and build up steadily inside the buffer silo, which delivers a continuous, uniform feed stream to support downstream manufacturing processes.

When the stored material volume reaches the preconfigured threshold, the integrated sensing assembly automatically activates the discharge valve. Stocked material is then released into the internal grading chamber to undergo high-accuracy particle size screening and separation. After classification, particles that fall within production specification ranges are routed to the dedicated collection hopper. By unifying feeding, buffer storage and grading in one closed automated cycle, this
