The LS series screw conveyor is a continuous conveying equipment without a flexible traction mechanism. It is mainly used to convey powdery, granular and small lump materials that are less sticky and difficult to agglomerate, such as coal, slag, cement, grain, etc. , can be widely used in building materials, chemical industry, electric power, metallurgy, coal and other industries. This series of equipment is generally used for short-distance continuous transportation of bulk materials in a horizontal or slightly inclined (inclination angle β ≤ 15°) direction, and can mix and stir the materials during the transportation process. The working environment temperature is -20 ~ 50℃, the temperature of conveyed materials is less than 200℃. 

Main product advantages of LS series screw conveyor

1. Since the conveying process is a fully enclosed operation, and the improved sealing structure ensures no dust leakage, it truly realizes clean and environmentally friendly production, and is especially suitable for conveying materials that are prone to dust, are hot (below 200°C), and have strong odors;

2. Multi-point feeding and multi-point unloading can be carried out according to the user's process layout requirements;

3. With the improved trough structure, the overall rigidity has been greatly improved, while the conveying resistance is smaller and the wear is smaller;

4. The axial and radial dimensions of the suspension bearing with optimized appearance are significantly reduced while maintaining the same rigidity, and there is no jamming or clogging of materials; at the same time, the suspension bearing seat is made of wear-resistant materials and is resistant to wear and tear. The grinding performance is better and the service life is longer;

5. Compact structure, few wearing parts, easy installation, operation and maintenance.

Working principle of LS series screw conveyor:

The working principle of the LS series screw conveyor is that when the material is added to the fixed trough from the feeding port, the material accumulated in the lower part of the trough does not rotate with the spiral blades under the combined action of the gravity of the material and the friction with the trough. It moves forward under the action of rotating spiral blades until it is discharged from the discharge port, thereby realizing material transportation.

LS series screw conveyor structural features:

The LS series screw conveyor is mainly composed of a spiral blade shaft, a trough, a hanging bearing, a transmission device, a support device, an inlet and outlet, etc. The main structural features of each part are as follows:

1. The head and tail bearing seats are arranged outside the trough, which prevents dust from entering the bearings and makes installation and maintenance more convenient;

2. The optimized spiral blade solves the problem of material blockage at the discharge port;

3. The spiral spindle adopts a variable diameter structure, which increases the volume of the hanging bearing, thereby reducing the contact between the hanging bearing and the material and reducing its wear;

4. The connection between the spiral shaft and the hanging bearing adopts embedded installation, and no axial movement is required during installation and disassembly, so maintenance and inspection are convenient;

5. The overall structure of the suspension bearing is compact and the axial and radial dimensions are small, which can avoid the occurrence of material jamming;

6. The suspension bearing is equipped with an improved sealing and lubrication device, which effectively protects and lubricates the bearing and significantly increases its service life;

7. The hanging bearing is fixed at the connection of each section of the spiral shaft, which not only ensures the coaxiality of the spiral shaft, but also improves its overall stiffness.
