Screw Feeder

1.Product Overview

A screw feeder is a quantitative,continuous feeding device that uses rotating spiral blades to push and meter bulk materials.It features compact structure,fully sealed design and adjustable feeding speed.Widely used for uniform feeding and quantitative batching in mining,chemical,environmental protection,building materials,food and pharmaceutical industries.

2.Working Principle

The motor and reducer drive the internal screw shaft to rotate stably.Materials are steadily pushed and transported by spiral flights.By adjusting the rotating speed,running frequency or blade pitch,it realizes accurate quantitative feeding and stable material supply for downstream equipment.

3.Main Structure

Drive assembly:motor,gear reducer,chain or gear transmission

Core part:screw shaft and wear-resistant spiral flights

Trough/tubular casing,feeding inlet and discharge outlet

Bearing assembly,sealing parts and adjusting device

4.Core Advantages

Precision dosing:Steady and uniform material output,easy to control feeding capacity.

Anti-dust&sealed:Fully enclosed structure,no dust leakage,eco-friendly and clean.

Wide material adaptability:Suitable for powder,granules,small lump materials such as fly ash,cement,ore powder,grain and chemical raw materials.

Simple installation&low maintenance:Small occupation,stable operation and long service life.

Customized design:Horizontal,inclined,high-temperature and anti-corrosion types are optional.

5.Application

It is commonly matched with crushers,mixers,dryers,conveyors and dust removal equipment,used for automatic quantitative feeding,raw material batching and continuous material conveying in industrial production.
