The use of screw feeder

I. Introduction

    Screw conveyor commonly known as the dragon, plastic, minerals, feed, grain and oil, construction industry, a wider use of a transport equipment, the direction of displacement from the conveyor material division, screw conveyor is divided into horizontal screw conveyor and vertical Screw conveyor two types, mainly for a variety of powdery, granular and other loose materials, horizontal transport and vertical lifting.

Second, the application:

    Screw conveyor for all industries, such as building materials, chemicals, electricity, metallurgy, coal, grain, etc., the material temperature is less than 200 ℃. Spiral machine is not suitable for conveying perishable, sticky, easy to caking materials.

    Screw conveyor generally consists of the conveyor body, the inlet and outlet and drive the three major components; screw conveyor spiral spiral surface of the entity, the belt-type spiral surface and the spiral surface of the three forms, of which the spiral blade surface applications Relatively small, mainly used for conveying large viscosity and compressibility of materials, this spiral suspension type, in the completion of the delivery process, at the same time to complete the material mixing, mixing and other functions.

Third, the use of the environment

    Screw conveyor use ambient temperature is usually -20-50 ℃; which, horizontal screw conveyor, the conveying material temperature should be less than 200 ℃; conveyor angle β should generally be less than 20 º; transmission distance is generally less than 40m, the maximum does not exceed 70m.

Fourth, the working principle:

    Screw conveyor is the use of rotating the screw will be transported along the fixed material to move the shell to carry out the work, the head and tail bearings to move outside the shell, hanging bearings with sliding bearings with dust seals, bearings generally use powder Metallurgy, transportation of cement with felt pad, the new machine is strictly prohibited idling; must be added to the material; re-test positive and negative; motor left to the normal increase in material;

Fifth, the main features:

   1, carrying capacity, safe and reliable.

   2, applicability

   3, easy installation and maintenance, long life.

   4, the whole small size, high speed, to ensure rapid and uniform delivery.

   5, low noise, strong adaptability, flexible layout of the inlet and outlet location.

   6, good sealing, shell made of seamless steel pipe, the end of the flange connected to each other into one, good rigidity
