Why Choose Qingdao Ruichen Screw Conveyor?
Modern industrial production requires conveying equipment that is efficient, durable, and environmentally friendly. Our screw conveyors are designed to meet these requirements while minimizing maintenance and maximizing operational reliability.
High Conveying Efficiency
The rotating screw continuously pushes materials along the conveyor, ensuring smooth and uninterrupted material flow.
Compared with intermittent conveying equipment, screw conveyors provide stable feeding, making them suitable for automated production lines.
Excellent Dust Sealing
The fully enclosed housing effectively prevents dust leakage during conveying.
This sealed design helps maintain a clean production environment while reducing material loss, making it particularly suitable for dusty materials such as:
Fly ash
Bottom ash
Cement powder
Lime
Mineral powder
Chemical powders
Grain products
Optional venting systems can also be integrated for special operating conditions.
Flexible Installation Layout
Our screw conveyors can be configured according to different plant layouts.
Available installation configurations include:
Horizontal screw conveyor
Inclined screw conveyor (typically up to 20°)
Combined horizontal and inclined conveying systems
Customized inlet and outlet positions
Multiple discharge points
This flexibility allows easy integration into both new production lines and retrofit projects.
Precise Material Feeding
Variable-speed drives can be installed to accurately control conveying capacity.
This enables the screw conveyor to function not only as a conveying device but also as a metering feeder in automated production systems.
Low Maintenance Design
The conveyor structure consists of relatively few components, resulting in:
Easy installation
Simple maintenance
Long service life
Reduced downtime
Lower operating costs
Wear-resistant hanger bearings and replaceable wear components further extend equipment lifespan.
High Temperature Capability
For high-temperature materials, Qingdao Ruichen offers customized designs including:
Heat-resistant steel construction
Water-cooled screw shafts
Water-cooled housing
High-temperature bearings
Thermal expansion compensation
Customized solutions can handle conveying temperatures up to 400°C, making them suitable for hot ash and clinker conveying applications.
Intelligent Safety Protection
To improve equipment reliability, optional monitoring systems include:
Plug detection
Overload protection
Bearing temperature monitoring
Rotation speed monitoring
Motor protection
Emergency shutdown systems
These intelligent features help prevent unexpected failures while improving plant safety.
Working Principle
A screw conveyor operates through the rotation of a helical screw mounted on a central shaft.
As the screw rotates inside the enclosed housing, bulk materials are continuously pushed toward the discharge outlet.
The conveying process provides:
Because materials remain enclosed during transport, screw conveyors are particularly suitable for environmentally sensitive industrial applications.
