Working principle of Spiral Conveyor
A spiral conveyor is a machine that uses a motor to drive a screw to rotate and push materials to achieve the purpose of conveying. It can be transported horizontally, obliquely or vertically, and has the advantages of simple structure, small cross-sectional area, good sealing, convenient operation, easy maintenance, and convenient closed transportation. In terms of conveying form, screw conveyors are divided into two types: shafted screw conveyors and shaftless screw conveyors. In terms of appearance, they are divided into U-shaped screw conveyors and tubular screw conveyors. The shaft screw conveyor is suitable for non-viscous dry powder materials and small granular materials. (For example: cement, fly ash, lime, grain, etc.) and the shaftless screw conveyor is suitable for conveying viscous and easily entangled materials. (Example: sludge, biomass, garbage, etc.)

Features
1. Adopt one-time forming spiral blade, with small pitch error and dynamic balance.
2. The use of no-cut tube, the overall rigidity is good, no dust leakage, stable.
3. With good quality bearings to determine the delivery.
4. The use of reducer, heavy-duty design, has the characteristics of large torque, low noise, no oil leakage, and long life.
5. The double-pitch design of the screw conveyor reduces the degree of compression of materials during transportation.
6. The screw conveyor is suitable for horizontal or inclined conveying of powdery, granular and small block materials, such as coal, ash, slag, cement, grain, etc. The temperature of the material is less than 200 °C, and it is not suitable for conveying perishable, viscous, Materials that tend to agglomerate.
7. The screw conveyor provides a variety of interface connection methods such as spherical hinge, nozzle, flange, square flange and so on.

Like the GX type Spiral Conveyor, it is used for one-way conveying with a horizontal or inclination angle less than 20°.
The Structure

Structural composition
Spiral Conveyor is mainly composed of driving device, head assembly, casing, shaftless spiral body, tank lining plate, feeding port, discharging port, machine cover (when necessary), base and so on.
1. Driving device: Cycloidal pinwheel reducer or shaft-mounted hard-tooth surface gear reducer is used. In the design, the driving device should be set at the end of the discharge port as much as possible, so that the screw body is in a tension state during operation.
2. The head is equipped with a thrust bearing, which can bear the axial force generated when conveying materials.
3. Chassis: The chassis is U-shaped or O-shaped, with a rain-proof cover on the upper part, and the material is stainless steel or carbon steel or glass fiber reinforced plastic.
4. Shaftless spiral body: the material is stainless steel or carbon steel.
5. Tank lining board: the material is wear-resistant plastic plate or rubber plate or cast stone plate, etc.
6. Inlet and outlet: There are two kinds of square and round. Generally, the form of inlet and outlet is determined by the user.
Which industries or materials are Spiral Conveyor suitable for?
Horizontal Spiral Conveyors can be used for powder, granular and small block materials in various industries for conveying, metering, cooling, mixing, separation, compaction and loading. According to your requirements, horizontal Spiral Conveyors can achieve dust-proof, gas-free Tight or watertight, thus protecting not only your product from external influences, but also the environment.
Materials that Spiral Conveyors are not suitable for conveying:
Such as: Coal mine, ash, slag, cement, grain, recycled rubber powder, zinc oxide, calcium carbonate, etc., the material temperature is less than 200 ℃. The screw machine is not suitable for conveying materials that are perishable, viscous, and easy to agglomerate.

Different feeding methods

Several common conveying methods
According to the working conditions on site, the conveying methods of the Spiral Conveyor are as follows. In special cases, please contact our sales staff to make the most suitable solution.When choosing a deep Spiral Conveyor, please note the following:

Various types

Introduction to the correct operation
1. When the screw shaft rotates, due to the gravity of the material and the frictional force generated by the tank wall, the material can only move forward along the groove bottom of the conveyor under the push of the blade, and it seems that it cannot rotate. The nut moves in translation along the rotating screw.
2. The movement of materials in the intermediate bearing depends on the thrust of the materials advancing behind them. Therefore, the transportation of materials in the conveyor is all a sliding movement.
3. In order to make the screw shaft in a more favorable tension state, the drive device and the discharge port are generally placed at the same end of the conveyor, and the feed port is placed as close as possible to the tail of the other end.
4. The rotating screw blade pushes the material for conveying, so that the force that the material does not rotate with the Spiral Conveyor blade is the weight of the material itself and the frictional resistance of the Spiral Conveyor casing to the material.
5. The surface type of the blade includes solid surface type, belt type surface type, blade surface type and other types according to the different conveying materials. The screw shaft of the Spiral Conveyor has a thrust bearing at the end of the material moving direction to give the screw axial reaction force with the material. When the length of the machine is long, an intermediate hanging bearing should be added.
6. The tubular Spiral Conveyor is mainly used for horizontal and vertical conveying of various powdery, granular and small pieces of loose materials.
7. The material will produce friction on the side wall of the tubular Spiral Conveyor, so it is very important to choose the size of the reducer and motor to drive the tubular Spiral Conveyor. As for the feeding method of the tubular Spiral Conveyor, the material must be fed into Jiaolong from the feeding port at first. Many manufacturers use this method to realize the feeding work.
Maintenance
1. Regularly check whether the transmission chain of the Spiral Conveyor is worn or not. If there is any abnormality, please replace it in time.
2. Check whether the link bolts of the chain plates of the Spiral Conveyor are tightened. If they are loose, they should be tightened in time.
3. Check the tension of the transmission chain of the Spiral Conveyor. Too loose and too tight will easily lead to bearing wear.
4. Regularly check whether the lubricating oil of the chain conveyor reducer needs to be added.
5. There must be no foreign matter in the Spiral Conveyor, which may easily cause chain jams, etc., and should be cleaned up in time.
6. Frequent startup, overload startup and full-load startup are prohibited.
Precautions for operation
1. Before starting the Spiral Conveyor, carefully check whether there is any remaining dust and debris in the machine groove;
2. The feeding must be uniform;
3. A screen should be added to the feed port of the Spiral Conveyor;
4. The machine slot and machine slot cover must be careful;
5. Before shutting down, the materials in the machine should be unloaded as much as possible;
6. When the machine stops in the middle of the operation, the materials in the machine should be unloaded as much as possible, and the materials in the machine cannot be discharged in time;
7. Regularly check the wear of the spiral blades;
8. Each lubricating part of the conveyor should be lubricated in strict accordance with the requirements;
9. When making harsh noises, it should be checked in time;
10. The bearings at both ends of the Spiral Conveyor should be strictly sealed;
11. Pay close attention to monitor the temperature exceeding the allowable temperature.
