Product Description

Small Tubular Limestone Rock Screw Conveyors Made of Stainless Steel

The introduction of  screw conveyor:

As a custom-made type of GX screw conveyor,LS screw conveyor is made of carbon steel material. 

Its surface  is fine processed and powder coated. ES screw conveyor is consist of a tubular tank 

which has at least onedischarging hole and one feeding hole; the flanges on both ends of

tubular tank; the screw blades welded on the central tube; joint bushings on both ends of 

central tube; two end bearings (one of them is connected with driver) which contain self-

regulation enclosed unit; hanging bearing, whose number is depend on the overall length of 

screw conveyor. Besides, to satisfy users' demand, CAO tubular screw conveyor is equipped 

with motor and gear box. ES screw conveyor is medium loading type machinery.
 Functions of screw conveyor:

Sand screw conveyor is mainly applied to feeding and delivery these materials: cement and filler dust 

in concrete manufacturing plant, cold processing filler dust in asphalt mixing plant, and cement and related 

materials in building material treatment plant.

Characteristics of screw conveyor 

1.Powder coated surface.

2.7 kinds of standard calibers.

3.There are welded end flanges, feeding hole, and discharging hole on the surface of tube. 

   The observing port is under feeding hole and hanging bearing.

4.There are standard flange sections inside the tube. One of the sections can be used to measure.

5.The screw blades are welded on the central tube.

6.Self-regulation enclosed unit is contains in end bearing components.

7.Spline bushings.

8.Every tube has a lashing eye.

9.Standard flange electric engine.

10.Easy to maintain. Equipped with aluminum hanging bearing which has automatic lubrication bushing on it.

11.Small diameter, high efficiency, and high productivity.

12.Small size. Compact structure.

13.Few components and spare parts.

14.Economical and durable.

15.Easy to maintain.

16.Feeding hole and discharging hole can be used universally, which makes installation more conveniently.

17.Excellent performance.
