Features of this machine
- The hopper and feeder are integrated into a single structure with a wide opening,
allowing for smooth material flow into the screw and minimizing bridging. - The hopper connects to the feeder at a sharp angle, leaving minimal residual material.
- Unlike conventional screw feeders, which were difficult to disassemble, the screw in this design can be easily dismantled.
- Increasing the hopper capacity is simple—just add a straight extension section.
Combination of Screw feeder and Vacuum conveyor
Screws are selected according to powder type and feeding capacity
We offer single-shaft and twin-shaft.
The single-shaft screw is a highly versatile standard specification, while the twin-shaft screw is used for crushing or high precision, depending on the type of raw material. Since this is the most important basic component, we select the optimum one according to the customer’s required specifications.
