From Raw Material to Finished Product: The Manufacturing Journey
The quality of a conveyor drum is determined by a meticulous manufacturing process. As a leading belt fastener manufacturer and drum supplier, we adhere to stringent quality controls at every stage. Here's a transparent look at our process:
1. Material Selection & Inspection
Certified steel plates (e.g., Q235, SS316L) are sourced and undergo ultrasonic testing to detect internal flaws. Material composition is verified via spectrometry.
2. Shell Rolling & Welding
Plates are precisely rolled into cylindrical shells. Submerged Arc Welding (SAW) is used for the longitudinal seam, ensuring deep penetration and a flawless, strong weld per AWS D1.1 standards.
3. CNC Machining & Assembly
End discs and shafts are CNC machined for perfect concentricity. The components are press-fitted and welded, followed by stress-relieving heat treatment to prevent deformation.
4. Magnetic Core Integration
A high-energy permanent magnet core (using NdFeB or Ferrite magnets) is installed. The magnetic circuit is computer-optimized for maximum field projection and separation efficiency.
5. Dynamic Balancing & Final QC
The assembled drum is dynamically balanced to ISO 1940-1 G16 standards. Final checks include TIR measurement, weld inspection (X-ray/UT), and surface coating thickness verification.
This rigorous process, combining forging, precision CNC machining, and certified welding, guarantees a product that not only meets but exceeds industry standards, ensuring an exceptional service life of over 50,000 hours under specified operating conditions.

Application Case Study: Enhancing Efficiency at a Major Steel Mill
The Challenge:
A leading steel production facility was experiencing frequent conveyor downtime due to premature failure of their slag conveyor head pulley. The existing drum suffered from rapid shell wear and bearing failure caused by intense heat and vibration. Inefficient magnetic separation also led to tramp metal damaging downstream equipment.
Our Solution:
Our engineering team conducted an on-site analysis and proposed a custom Slag Discharge Conveyor Drum. The solution featured a 20mm thick, wear-resistant manganese steel shell, a high-temperature NdFeB magnetic core, and SKF high-temperature bearings. The drum was dynamically balanced to G16, and the shaft was made from forged 42CrMo steel for superior strength.
The Results:
"The custom magnetic drum from these conveyor magnet suppliers has been a game-changer. We've seen a 99.8% separation efficiency, and unplanned downtime on this line has been reduced by over 80%. The drum has been running flawlessly for 18 months in an environment where previous drums failed within 6. It was a sound investment that paid for itself in less than a year."

Frequently Asked Questions (FAQ)
A magnetic head pulley (like our Slag Discharge Conveyor Drum) replaces the standard head drum of a conveyor. It provides continuous, automatic separation as material is discharged over the pulley. Ferrous metal adheres to the belt until it passes the magnetic field underneath. An overband separator is suspended above the conveyor belt. It lifts ferrous metal up and off the product stream. Head pulleys are generally more effective for deeper burden depths and have fewer moving parts, making them ideal for many conveyor magnet suppliers' core offerings.
The required Gauss rating depends on several factors: the size and nature of the ferrous contaminants, the belt speed, and most importantly, the burden depth (the thickness of the material layer on the belt). A deeper burden requires a stronger magnetic field with greater projection. Our technical team can perform calculations based on your operational parameters to recommend the optimal magnetic strength for effective separation.
For high-temperature applications like slag handling, standard Q235 carbon steel is insufficient. We recommend high-manganese steel for its excellent work-hardening and abrasion-resistant properties. For the magnetic core, special high-temperature grade Neodymium (NdFeB) or Samarium-Cobalt (SmCo) magnets are used, as standard magnets lose their strength permanently when exposed to excessive heat.
Dynamic balancing corrects for uneven mass distribution along the entire length of the drum. An unbalanced drum, especially at high speeds, will create significant vibration. This vibration leads to premature bearing failure, structural fatigue in the conveyor frame, belt mistracking, and increased energy consumption. Balancing to a strict standard like ISO G16 ensures smooth, stable operation, drastically increasing the lifespan of the entire system. Any expert belt fastener manufacturer will confirm the importance of a well-balanced drum for belt longevity.
Absolutely. We specialize in designing our drums as drop-in replacements for existing head pulleys. We take precise measurements of your current setup, including shaft diameter, shaft length, bearing centers, and overall drum dimensions, to ensure a seamless installation with minimal modification to your existing structure.
Our drums are designed for low maintenance. The primary requirements are: 1) Regular lubrication of the bearings according to the bearing manufacturer's schedule. 2) Periodic inspection of the drum surface for wear, especially the lagging. 3) Ensuring the conveyor belt is properly tensioned and tracked to prevent uneven wear. The internal magnetic assembly is permanent and requires no maintenance.
We adhere to a suite of international standards. Our quality management system is ISO 9001:2015 certified. Dynamic balancing conforms to ISO 1940-1. Welding procedures can be qualified to AWS D1.1 or equivalent standards. Dimensional tolerances and design principles are often aligned with CEMA (Conveyor Equipment Manufacturers Association) and ANSI B105.1 standards for conveyor pulleys, ensuring interoperability and safety.
