Our multi-shaft screw conveyors are engineered for the flour milling industry, specifically designed for efficient transportation of cereal grains, flour, and by-products like bran. Constructed from durable carbon steel with food-grade surface finishing, these conveyors deliver reliable performance in demanding industrial applications.
Construction Details
U-shaped trough design with multiple outlet spouts
End plates at each trough termination point
Helicoid screw flighting welded to center pipe with coupling bushes
Dual end bearing assemblies with integrated shaft sealing units
Intermediate hanger bearings with self-lubricating bushes (quantity varies by length)
Secure bolted trough covers for easy maintenance
Key Conveying Features
Our shaftless screw conveyors excel in handling viscous materials across multiple industries including chemical processing, food production, pharmaceuticals, paper manufacturing, beverage processing, and environmental applications. They are particularly effective for transporting:
High-viscosity materials
Paste-like substances (chemical raw materials, waste pulp, malt, sludge)
Materials prone to winding or tangling
Performance Advantages
Environmental Protection: Fully enclosed design prevents material contamination during transport
Enhanced Capacity: Delivers 1.5x the volume of traditional shaft conveyors with equivalent diameter
Reliable Operation: Minimal risk of blockages during continuous use
Extended Reach: Capable of transmission distances up to 60-70 meters
Space-Efficient Design: Compact footprint with user-friendly operation and competitive pricing
Operational Requirements
a. Startup Procedure: Always initiate operation without load (empty casing). Begin feeding only after the conveyor is running.
b. Feeding Protocol: Gradually increase material input to reach rated capacity. Maintain consistent feed rates to prevent material accumulation and equipment overload.
c. Shutdown Process: Cease feeding before stopping operation to ensure complete material discharge from the casing.
d. Material Specifications: Avoid conveying hard contaminants that could cause jamming or mechanical damage.
e. Maintenance Checks: Regularly inspect all components during operation. Immediately tighten any loose fasteners to maintain structural integrity.
f. Safety Precautions: Never remove the protective cover while the conveyor is in operation.
