Introduction
The screw conveyor is divided from the angle of the displacement direction of the conveying materials. The screw conveyor is divided into two types: horizontal screw conveyor and vertical screw conveyor. It is mainly used for horizontal conveying and vertical lifting of various loose materials such as powdery, granular and small blocks. This machine is not suitable for conveying special materials that are easy to deteriorate, viscous, easy to agglomerate or high temperature, afraid of pressure, and have greater corrosion
Screw conveyor is widely used in various industries, such as building materials, chemical industry, electric power, metallurgy, coal mine carbon, grain and other industries, suitable for horizontal or inclined conveyance of powdery, granular and small bulk materials, such as coal mines, ash, slag, cement, grain, etc. Material temperature is less than 200 ℃.

It is widely applied across industries such as building materials, chemicals, electric power, metallurgy, coal, and grain processing. This conveyor is engineered to deliver consistent performance while handling materials like cement, coal, ash, slag, and grain, with a recommended material temperature below 200°C. However, it is not suitable for transporting materials that are highly viscous, prone to agglomeration, corrosive, temperature-sensitive, or easily perishable.
Featuring a robust design, the screw conveyor is categorized into horizontal and vertical types to suit different operational layouts and material displacement needs. Its working mechanism relies on a rotating helical screw blade, which moves materials efficiently along a trough or pipe. Key advantages include a simple structure, reliable operation, low maintenance requirements, and compact installation flexibility. Available in multiple models—such as the LS200 to LS1250 series—the conveyor offers a wide range of technical parameters, including spiral diameters from 200mm to 1250mm, adjustable rotational speeds, and volumetric delivery capacities tailored to specific application needs. This ensures optimal performance whether used for feeding, dosing, or transferring materials in demanding industrial environments.
