New Design Stainless Steel Material Food Powder Screw Conveyor

Introduction

Screw conveyor is a kind of continuous transmission equipment which without immunity traction components, it uses rotation screw to convey material. The screw conveyor is of simple structure, low marking cost, strong sealing, safe ,convenient operation and other advantages, It allows multiple inlets and outlets. It is widely used in various industrial department(such as building materials, chemicals, electric power, metallurgy, coal, mine, food and other industries)to convey powder, granular and lump material, such as, coal, ash, slag, cement, food, etc. The temperature of material is less than 200°C. Screw conveyor is not suitable for transporting those material which is perishable, with big viscous and easy caking. In the concrete mixing plant screw conveyor's effect reflected to the fullest. 
 

Application:

Loose materials such as powder, granular and small piece material , which includes: clay powder, pulverized coal, cement, sand, grain, small piece of coal , cobble, and cast iron filings, etc.

It is widely used for the loose cement transportation from cement warehouse to mixer or from cement warehouse to mpounding machine in concrete mixing plant.
 

Working  principle

Screw conveyor is relying on a spiral blade shaft in the trough of closed continuous rotation in order to impel the lose of material moving. At this time, the material are like the bolt, in spinning along the axial moving forward gradually, finally discharging mouth off.

Screw conveyor Structure

The structure of the screw conveyor, mainly by the drive device, discharge hole, rotating screw axis, bearings, housing and feeding port, etc. Usually screw conveyor has the bearing on the material movement terminal side, it can withstand the material to spiral axial force of the blade. When the conveyor is longer than the fuselage, it should be added the middle hanging bearing.



 

Characteristic

1. Efficient delivery : small diameter , high rotating speed, large transmission capacity, variable pitch of spiral body, and small resistance of intermediate bearing make loading material smoothly, quickly and evenly.

2. Random arrangement : conveyor has good integral rigidity and can transport the products flatly or steeply inclined, it can be connected with its corollary equipments directly , and can be set up and dismantled easily with small floor space.

3. Good lubrication : low oil lubricating sliding tile, multilayer labyrinth oil seal design and integral lubricating system composed of of oil pump, distributor and pipeline are convenient and can completely lubricate all the running parts. 

4. Reliable sealing : the dust cover of reducer is reliable for preventing leakage which can protect reducer and create good working condition. Improved peephole can prevent water seepage and material leakage.
5. Diverse connection : feed inlet and outlet can be connected not only with universal ball, bag,flange etc but also butterfly valve and gate valve. 

6. Innovative design: special reducer designed and produced with introduced technology not only has the advantages of a small size, a big bearing torque.
