Working Principle and Common Applications of an Automatic Screw Feeding System

If you are interested in finding out about the working principal and applications of an automatic screw feeder, you are on the right page. After you have read this article, you will have a basic understanding of how the device works and what applications it offers for a lot of industries. Without further ado, let’s go into details.

Working Principle

First of all, the material is fed into the feeding box and then the switch is turned on. The feeding box at the bottom provides the feeding material to the outlet via the screw. Plus, there is a feature that allows you to adjust the time settings in the feeding system.

Based on the feeding quantity, you can easily adjust the time settings. The spring feeder follows the screw feeding principles set in the software program of the device.

Wire springs allow the unit to rotate the material from the storage to the sturdy plastic extruder. This process continues until the level device sends out the filling signal. After a while, the reciprocating cycle starts once again. Based on the requirements of the user, it’s possible to use the time relay in order to adjust the downtime and achieve the desired automation.

Fundamentally, an automatic screw feeder is used to feed a lot of material types, such as powder, granules, and plastic powder mixtures. Apart from this, it is used with injection molding units and extruders.

Apart from this, they can be used for other purposes, such as transportation of different types of powder-like talc or flour powder. As far as utility is concerned, these machines are strong, stable, and come with long service life. Therefore, you can count on these units.


As far as applications are concerned, you can use these devices in a number of ways. For instance, they can be used for powder feeding, powder mixtures, plastic granules and powder feeding, to name a few. The good thing is that these machines use a little power, unlike conventional units. In fact, the power consumption is just 30% of the old, conventional machines.

An automatic screw feeder is an ideal machine if you work in a chemical, food or plastic processing industry. The primary role of these units is to feed different types of materials in the form of powder.

This special equipment comes with a lot of adjustments. The contact material is strong enough as it’s made of high-grade stainless steel. Also, the raw material is free from pollution and there is no issue with foreign bodies. Therefore, the entire production process becomes automated and safe.

A mobile screw feeder comes with ease of installation and transportation. Also, if you fill the same material in multiple machines, you can use the same feeder for the feeding purpose. Therefore, there will be no problem with manual feeding. As a result, feeding becomes a lot safer and labor-saving.

In short, this was a brief look at the working principle and applications of an automatic screw feeder.
