KM Auger feeder is used to feed non-sticky powdery, granular and small particle materials from silos and other storage equipment to the receiving equipment evenly.It mainly consists of a material hopper (silo) and a single-tube screw conveyor.Under standard operating conditions, the screw conveyor is typically installed at an inclination of approximately 45 degrees, allowing stable and controlled material feeding.

1. Silo Part
2. Screw Conveyor Prat
3. Electric Control Part
A screw feeder is a mechanical device engineered to control and regulate the flow of bulk materials such as powders, granules, or pellets. It functions by using a rotating helical screw enclosed within a tube or trough, which ensures a consistent and controlled feed rate.
When positioned at a 45° upward incline, the screw feeder simultaneously performs feeding and lifting operations, making it ideal for applications requiring the elevation of materials to higher processing stages.

1). Shaftless Screw Feeder Conveyor
Shaftless screw feeders are specialized material handling units utilizing a single, helix-shaped spiral without a center shaft, designed to convey sticky, stringy, or abrasive materials—such as sludge, screenings, and industrial waste—without clogging. They offer high-volume handling with higher fill rates and lower RPM compared to shafted alternatives
2). Dust-Free Feeding Station
Dust-Free Feeding Station (also known as a bag dumping station) is a specialized material handling system designed to safely discharge powders or granules from bags while preventing dust from escaping into the factory environment.
3). Stirrer inside the Hopper
The stirrer inside a screw feeder’s hopper, often referred to as an agitator or bridge-breaker, plays a critical role in ensuring the continuous flow of material from the storage section into the rotating screw.
4). U shape screw feeder
Unlike tubular feeders, the U-shape typically features a removable flat cover. This provides easy access for cleaning, inspection, and maintenance without needing to dismantle the entire pipe.The cover is usually bolted down with a gasket to prevent dust escape, which is essential for “Dust-Free” operations.
5). Adjusted Discharge height
Adjusted the screw feeder discharging height by pneumatic cylinder to suit for different environment
6). Vertical Screw Feeder
Vertical screw feeders are designed to lift bulk materials at steep angles, typically 90 degrees (straight up). Because gravity works directly against the material flow, these machines require higher rotational speeds and specific design features compared to horizontal feeders.
