Rotary Unloader

1.Introduction

Rotary unloader is a robust,high-efficiency bulk material discharge solution,engineered for continuous material handling under positive and negative pressure conditions.Commonly mounted beneath dust collectors,cyclone separators,storage silos and hopper systems,it reliably discharges powders,granules and fine lump materials while delivering superior airtight performance.It acts as a vital buffer and pressure isolation unit to stabilize overall production and pneumatic conveying processes.

2.Working Principle

Equipped with a low-speed driving system,the precision multi-vane rotor rotates steadily inside a fully enclosed housing.Material fills the rotor’s cavity compartments by gravity from the upper inlet,then is mechanically transported to the bottom outlet and discharged evenly.The precise clearance between rotor and casing creates a durable air barrier,which effectively stops air backflow,pressure loss and material dust leakage.

3.Structural Composition

Heavy-duty drive system including motor and gear reduction unit

High-rigidity welded or cast housing with standard flange connectors

Reinforced wear-resistant rotor with optimized cavity design

Premium shaft sealing and dust-proof bearing assembly

Optional wear-resistant lining,anti-clogging structure and service access cover

4.Product Strengths
