Incline Screw Conveyor Manufacturer
What is an Incline Screw Conveyor?
An Incline Screw Conveyor is a mechanical bulk material handling system that transports powders, granules, and semi-solid materials upward at a defined angle using a rotating helical screw blade inside a sealed trough or tubular casing.
Unlike horizontal screw conveyors, inclined models are designed to overcome gravitational resistance. They are widely used in industries such as food processing, pharmaceuticals, chemicals, agriculture, plastics, and construction to move materials between different elevation levels in a compact, enclosed, and dust-free manner.
Key Specifications:
- Inclination Angle: 15° to 90° (customizable)
- Screw Diameter: 100 mm to 600 mm
- Capacity: Up to 100 TPH
- Construction Material: Mild Steel (MS) or Stainless Steel (SS 304 / SS 316)
- Drive: Motor + Gearbox assembly
Working Principle of Incline Screw Conveyor
The working principle is based on the rotation of a helical screw inside a fixed casing. When bulk material enters through the lower inlet hopper, the motor-driven screw rotates and exerts axial thrust and frictional force, pushing the material upward toward the discharge outlet.
As the incline angle increases, gravity resists material flow — requiring higher torque, modified screw pitch, and optimized RPM. JS Vibro’s incline screw conveyors are engineered to maintain consistent throughput even at steep angles, minimizing material rollback and energy loss.

Types of Incline Screw Conveyors We Manufacture
Choosing the right incline screw conveyor requires careful evaluation of material and operational requirements. Start by analyzing the material properties, such as density, moisture, particle size, and flowability, as these directly affect conveyor performance . Next, determine the required capacity and conveying height, which influence screw diameter, pitch, and motor power. Consider the inclination angle, since efficiency decreases at steeper angles and may require higher torque or modified screw design. Select the appropriate construction material (mild steel or stainless steel) based on the application and environment. Also, assess maintenance needs and space constraints. A properly selected conveyor ensures efficient operation, reduced downtime, and long-term reliability in industrial material handling systems.
Types of Incline Screw Conveyors We Manufacture
Tubular Incline Screw Conveyor — Fully enclosed pipe design for dust-sensitive materials like flour, cement, and fine chemicals.
Trough-Type Incline Screw Conveyor — U-shaped trough suitable for coarser, heavier bulk materials with moderate inclination.
Vertical Screw Conveyor (90°) — For applications requiring straight vertical elevation in a minimal footprint.
Portable Incline Screw Conveyor — Mounted on wheels or skids for flexible use across production areas.
SS Incline Screw Conveyor — Stainless steel construction for hygienic, corrosion-resistant operation in food and pharmaceutical plants.
How to Choose the Right Incline Screw Conveyor?
Selecting the right incline screw conveyor depends on several critical factors:
- Material Properties — Assess bulk density, particle size, moisture content, abrasiveness, and flowability. Sticky or cohesive materials may need special screw coatings or modified pitch.
- Inclination Angle — Efficiency drops beyond 30°. Angles above 45° require a modified short-pitch screw and higher torque motor to prevent material rollback.
- Required Capacity (TPH or m³/hr) — Determines screw diameter and shaft speed. Higher capacity needs larger diameter and optimized RPM.
Conveying Length & Height — Influences the shaft length, number of intermediate bearings, and required motor power. - Material of Construction — Mild steel for standard applications; SS 304 or SS 316L for food, pharma, or corrosive materials.
Environment & Compliance — Consider ATEX rating for explosive atmospheres, or FDA-grade materials for food/pharma.
