Specification of volumetric screw feeder

Screw feeder

Small and compact size

Our screw feeders are not as big as conveyors. However, it does not require such a large installation space. We manufacturer large variety of size that can be placed on the table. They are able to be easily disassembled without any tools, and cleaned. We are sure, that this machine absolutely easily-handleable machine with no doubt.

Large variety of sizes

We manufacture many sizes to meet the needs of our customers. There are many types of powder, each with different properties and characteristics. After listening to their requirement, we will suggest the best feeder for feeding. We have created various type of handling equipments,so we promise they will definitely be able to meet you desire.

Agitator

Measures to bridge

Bridges are one of the most common problems in feeding,or dosing powder. Bridge is a phenomenon in which powder is clogged and it becomes hard to flow well. As a typical measure, we recommend an agitator (stirring blade). However, depending on the type of powder, we recommend using an air vibrator. We propose the best answer according to your situation.

Customizable products

Our strength is that we can customize and manufacture material handling equipment, such as screw feeder and conveyor, according to customer’s request. The place you plan to install it and the equipment you wish to connect vary depending on the environment of your factory or laboratory. We are not manufacturers who makes only certain products.We would like to manufacture your own custom-made equipment, not only to sell products but also to make proposals for solving customers’ problems.

Stainless round hopper

Hopper
Screw feeder

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
We also have an agitator (bridge breaker) = stirring blade for bridging measures
for preventing powder bridging (powder clogging due to agglomeration) in the hopper.
As with the screw, the rotation speed can be adjusted with the inverter.
The shape of the blade also corresponds to the powder characteristics.
