LS type screw conveyor

LS type screw conveyor is used in industrial sectors such as building materials, power, chemical, metallurgical, coal, aluminum magnesium, mechanical light industry, grain and food industries. It is suitable for conveying powdery, granular and small block materials with a horizontal or less than 20 degree inclination angle, such as cement, coal powder, grain, fertilizer, ash, sand, etc. The material temperature is below 200 ℃. It has the advantages of large conveying capacity, compact structure, energy saving and consumption reduction, light weight, and strong sealing.

The LS type screw conveyor has a novel structure and excellent technical indicators. The head and tail bearings are moved outside the shell, and the middle suspension bearing adopts two interchangeable structures of rolling and sliding. Both are equipped with dust-proof sealing devices, and the discharge end is equipped with a cleaning device. The whole machine has low noise, strong adaptability, easy operation and maintenance, and flexible layout of the inlet and outlet positions.

LS type screw conveyor is widely used in various industrial sectors, such as building materials, electricity, chemical industry, metallurgy, coal, aluminum magnesium, machinery, light industry, grain and food industry; Suitable for conveying powdery, granular, and small block materials such as cement, coal powder, grains, fertilizers, ash, sand, etc. at a horizontal or less than 20 ° inclination angle, with a material temperature below 200 ℃.

LS type screw conveyor is not suitable for conveying materials that are prone to deterioration, high viscosity, and easy agglomeration, because these materials will stick to the screw during transportation and rotate without moving forward or form material blockages at the suspension bearings, which will prevent the screw machine from working properly.

The LS type screw conveyor has five specifications with screw diameters ranging from 200 millimeters to 500 millimeters, and lengths ranging from 4 meters to 70 meters, with intervals of 0.5 meters. When selecting, the standard nominal length should be followed, and special requirements can be separately mentioned in the optional section.

According to the LS type screw conveyor driving method, it can be divided into two types: C1 method - single end driving when the length of the screw conveyor is less than 35m. C2 method - When the LS type screw conveyor is greater than 35m, it is driven at both ends.

According to the types of intermediate suspension bearings in LS type screw conveyors, M1- is a rolling suspension bearing that uses 80000 type sealed bearings. The shaft cover also has a dust-proof sealing structure, which is commonly used in places where oil is not easy to add, does not add oil, or where oil pollutes the material. It has good sealing effect, long service life of suspension bearings, and the temperature of the transported material is ≤ 80 ℃ (which may not be specified when ordering). M2- is a sliding suspension bearing equipped with a dust-proof sealing device, commonly used for conveying materials at high temperatures (> 80 ℃) or for conveying liquid materials.
