The screw conveyor has the features of simple structure, low cost, good airtightness and easy operation, etc.,and capacity of multi loading and unloading. It is vastly used in chemical, building material, metallurgic and grain industry. When the slanting angle β<20°, it has good performance, and which is characterized by fine conveying of low viscosity, performance constant, not agglomerate in shape of powder, particle and small pieces of materials.
According to the different uses and environments, screw conveyor has many new-type products.For example, the vertical conveyor type LC and type LS-Y used for blast furnace system, type XP and mono or double-barrelled screw feeder specially used in lime slaking.
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.
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.
We have successfully developed and put into batch production for Non-greasy lubricate screw conveyor.
1.Adopt non-greasy bearing, reliable in using and we guarantee 1.5 years.
2.Avoid trouble of oil injecting and save grease.
3.Simple in structure and easy for maintenance.
Adopt high-quality steel pipe with good integral rigidity.
Double pitches or three pitches design, which decrease the compression degree of material when
being transported and avoiding blocking.
Adopt high-quality reducer with heavy-duty design,large torque and low noise.
Adopt optional universal ball joint, which facilitates installation,adjustment and steering.
Inlet equipped with high-quality middle-hoisting bearing and tail bearing.
Sufficient spare parts with complete specification.
Large stock for common diameter of 168,219,273,323and 407,and dimension&angle can be
customized according to your requirement.
Assembled by standard parts and components, which makes it convenient for transportation.
Adopt Siemens motor.
III. Characteristics of Pellet 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.
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.
