Spiral Retrun Idlers

Spiral return idlers, also known as screw conveyor idlers or spiral rollers, are specifically designed for conveying sticky materials, featuring self-cleaning capabilities to ensure efficient operation. These idlers are primarily used on the return side of belt conveyors to clean the surface of the conveyor belt, reduce the impact of material buildup, and extend the lifespan of the equipment. Zoomry manufactures spiral return idlers using high-quality materials and precise manufacturing processes to ensure reliable performance even in demanding working environments.

■ Application Scenarios

Spiral return idlers are widely used in various belt conveyor systems, particularly in handling sticky or easily adhering materials. Their primary function is to prevent material accumulation, reduce damage to the conveyor belt, and improve conveying efficiency. Typical application scenarios include:

● Thermal Power Plants: In thermal power plants, conveyors are commonly used to transport materials such as coal and ash, which are often sticky and prone to buildup. Spiral return idlers effectively clear materials adhered to the conveyor belt, ensuring smooth operation of the system.

● Ports and Terminals: In ports and terminals, material handling systems need to efficiently transport large quantities of materials. Spiral return idlers are especially effective in dealing with wet or sticky materials that tend to adhere to the conveyor belt.

● Cement Plants: In cement production, conveyors are tasked with transporting large amounts of powdery and granular materials. Spiral return idlers effectively prevent material accumulation, reduce wear on the conveyor belt, and enhance production efficiency.

● Metallurgical Industry: In the metallurgy industry, conveyors are used to transport materials such as iron ore and coal dust, some of which are highly adhesive. Spiral return idlers use their self-cleaning function to prevent sticky materials from causing strain on the conveyor system.

● Chemical and Pharmaceutical Plants: In chemical and pharmaceutical production, large amounts of raw materials and powders need to be transported. Spiral return idlers help remove material buildup, ensuring the stability of the conveyor system and preventing material leakage and contamination.

● Agriculture and Food Processing: In agriculture and food processing, spiral return idlers are commonly used to transport sticky grains or moist materials, preventing them from accumulating on the conveyor belt and ensuring uninterrupted production.

■ Features

● Prevents Material Buildup: The unique spiral design of the return idlers effectively pushes material toward the edge of the conveyor belt, preventing accumulation and keeping the belt clean.

● Self-Cleaning Function: The surface of the idlers is specially treated to provide self-cleaning functionality, preventing material adhesion and reducing maintenance efforts.

● Efficient Sealing Design: Spiral return idlers are equipped with highly effective labyrinth seals, which prevent dust and water from entering the bearing, safeguarding the system from contamination and extending the lifespan of the idlers.

● Durability: Made from high-quality steel and sealed ball bearings, these idlers are designed for long-lasting performance and low maintenance costs.

● Low-Maintenance, Maintenance-Free Design: With sealed bearings and anti-corrosion treatment, spiral return idlers are designed to minimize maintenance requirements and lower operating costs.

● Adaptable to Harsh Environments: Whether in high, low, humid, or dry temperature environments, spiral return idlers maintain stable performance, making them suitable for a variety of challenging working conditions.

■ Product Types

● Standard Spiral Return Idlers

Standard spiral return idlers feature a conventional spiral design, suitable for most regular conveyor systems, effectively cleaning materials and keeping the conveyor belt free from buildup.

● Spiral Self-Aligning Return Idlers

These idlers can automatically adjust the alignment of the conveyor belt, preventing misalignment-related system failures. They are particularly useful in high-load, high-frequency conveyor systems.

● Corrosion-Resistant Spiral Return Idlers

For corrosive environments, these idlers are made from corrosion-resistant materials or treated with specialized coatings to withstand chemicals, moisture, and other environmental factors, ensuring a longer service life.

● High-Temperature Spiral Return Idlers

These idlers are designed for material transport in high-temperature environments, using heat-resistant materials and special bearing designs to ensure long-term stable operation in extreme heat.
