Screw feeder for powdered material

Designed for easy hopper removal
imply remove the knobs and slide them off

Coupling that connects the screw to the motor
Snap locks for easy removal.

Feed screw can be easily disassembled and cleaned
by simply removing 4 knobs

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.

Our screw feeders are not as large as conveyors. However, they do not require a large installation space. We manufacture many of them in sizes that can be placed on a table. They can be easily disassembled without tools and cleaned. This simple machine is easy to operate on a daily basis once you get used to it.

We manufacture a wide range of screw sizes to meet the needs of our customers. There are various types of powders, each with different properties and characteristics. We will listen to your needs and propose the most suitable feeding equipment. With our long experience and manufacturing track record, we promise that we will always be able to meet our customers’ needs.

A common problem in powder feeding is bridging. Bridging is a phenomenon in which powder clogs up and becomes difficult to flow. Agitators (agitator blades) are recommended as typical countermeasures. Depending on the type of powder, we also offer air vibrators and knockers. Bridging is a common problem with powdered raw materials, but we can offer the best solution according to the characteristics of those raw materials.

The standard hopper is made of round stainless steel (SUS304).
Outer surface / flange ・ ・ ・ 2B material
Inner surface ・ ・ ・ # 400 Abrasive

Hopper capacity can be selected from 10L to 100L
(20L is standard size)

Optional function
Agitating blades are recommended to prevent bridging.The agitator prevents powder bridging (clogging due to agglomeration of powders) in the hopper and supports quantitative feeding of raw materials. As with the screw, the speed of rotation can be adjusted with an inverter.
