Product Overview
The screw conveyor is a mechanical conveying device driven by a motor that rotates helical blades. Using friction and thrust between the blades and the material, it transports materials from one point to another. It is widely used across mining, building materials, chemical, grain, environmental protection, and other industries.
Its core structure is simple and compact, primarily consisting of a drive unit, enclosed trough casing, and helical blades. It comes in shafted and shaftless configurations: shafted screws are typically used for non-sticky materials, while shaftless screws handle sticky, easily entangled materials. The housing features a sealed design capable of conveying powders or liquid materials, effectively preventing material contamination and environmental dust pollution to meet eco-friendly production requirements. The screw shaft is fabricated from high-strength steel for high rigidity and minimal deformation, delivering high conveying efficiency with a reduced risk of material jamming.
Compared with traditional incline conveyors, the screw conveyor achieves substantial vertical lift within an extremely small footprint. It supports multi-directional conveying and strong adaptability, accommodating horizontal, inclined, and vertical angles without additional transfer equipment, flexibly connecting production lines at different heights and positions to meet diverse transfer needs.
Key Advantages
-
Sealed design prevents material contamination and environmental dust pollution, meeting eco-friendly production requirements.
-
Modular design ensures smooth operation, a simple structure, and low maintenance costs.
-
Wear-resistant and durable for a long service life. The helical blades and casing are made from wear-resistant materials with anti-corrosion and anti-abrasion surface treatments to withstand harsh conditions such as dust and moisture. Built for long-term use with minimal damage and low operating costs.
