Forever Electromechanical Completes Overseas Delivery of Big Steel Ball Mill Production Line Project

Forever Electromechanical, a professional source manufacturer of induction heating and metal rolling‑forging equipment, has successfully completed factory testing, shipment and on‑site commissioning for a full‑set big steel ball mill production line for an overseas mining‑oriented customer. This turn‑key project covers raw bar feeding, IGBT induction heating, hot rolling, quenching‑tempering heat treatment, finished‑product screening and inspection. It delivers large‑diameter high‑hardness grinding steel balls for local mineral processing plants, marking another milestone for Forever Electromechanical’s complete‑set metallurgical equipment in overseas heavy‑industry markets.

1. Project Background & Customer Pain Points

The end‑user is a large mineral processing enterprise in South America. Previously, the plant purchased finished grinding steel balls from third‑party suppliers. Long procurement cycles, unstable product quality and high logistics costs seriously restricted production output. The customer planned to build an in‑house big steel ball production workshop, expecting to independently produce high‑performance grinding balls with diameter ranging from 60 mm to 120 mm.

Local field conditions bring multiple challenges: unstable grid voltage, high ambient temperature, requirement for 24‑hour non‑stop continuous operation, as well as strict standards for steel ball hardness and anti‑fragmentation performance. After rounds of technical comparison, the customer finally selected Forever Electromechanical to provide full‑set customized production line solution including process layout, core equipment, automation system and after‑sales on‑site guidance.

2. Core Configuration & Key Technical Parameters of Production Line

This steel balll production line integrates induction heating, hot rolling forming and integrated heat‑treatment modules, adopting full‑digital IGBT intermediate‑frequency power supply as heating core. Main technical parameters are shown as below:

• Finished steel ball diameter: 60‑120 mm

• Production capacity: 2.5‑4 tons per hour

• Heating temperature: 1050‑1180 ℃ adjustable

• Power supply: IGBT intermediate frequency power supply, power factor ≥0.96

• Steel ball surface hardness: HRC 58‑64; impact toughness ≥12 J/cm²

• Fragmentation rate: ≤0.5%

• Control system: PLC central control + infrared temperature closed‑loop adjustment, with remote data‑monitoring function

• Applicable raw material: high‑carbon alloy steel round bar

All equipment adapts to local 60 Hz power grid standard. Key components adopt high‑temperature resistant and dust‑proof design to fit harsh on‑site working environment.

3. Core Competitive Advantages Realized On‑Site

First, integrated one‑stop turn‑key service. Forever Electromechanical provides overall process layout, equipment manufacturing, pre‑assembly test, overseas shipment, installation guidance and operator training. Customers do not need to coordinate multiple suppliers, greatly shortening the whole project construction cycle.

Second, stable heating quality reduces raw‑material waste. Optimized induction heating unit achieves uniform internal‑external temperature for steel bar blanks. Less oxide scale loss effectively improves finished‑ball yield rate.

Third, intelligent automatic operation reduces labor cost. From bar feeding, heating, rolling, quenching‑tempering to finished‑product sorting, most procedures run automatically. Only few operators are required for monitoring, lowering dependence on skilled workers locally.

Fourth, strong adaptability for local environment. Against unstable power supply and high‑temperature workshop condition, anti‑voltage‑fluctuation and heat‑dissipation optimization are carried out for power cabinet and control cabinet, lowering unexpected shutdown risk.

4. Project Operation Effect & Market Outlook

After full‑load commissioning acceptance, the screw rolling steel ball production line runs stably. The hardness, toughness and fragmentation‑resistance indicator of self‑produced large grinding steel balls fully satisfy ore‑grinding working condition. The customer significantly cuts purchasing cost of consumable grinding media and improves supply security of grinding balls.

In recent years, global mining and mineral‑processing industries keep rising demand for high‑quality large‑size grinding steel balls. Forever Electromechanical will keep optimizing hot‑rolled steel ball production line technology, expand supporting customized solutions for different capacity and ball‑size requirements, and deliver reliable metal thermal‑processing complete‑set equipment for more global metallurgy and mining clients
