Wet Grate Ball Mill 3200×4500 For Iron Ore Processing in Philippine

In a recent iron ore beneficiation project in the Philippines, the installation of a Baichy MQG 3245 (3200x4500mm) Wet Grate Ball Mill led to a significant production breakthrough. The plant successfully achieved a stable throughput of 80-100 TPH, reducing energy consumption by 20% through advanced roller bearing technology. The grate-type discharge mechanism prevented over-grinding, ensuring optimal particle size for subsequent magnetic separation.

Project Background: Scaling Up in the Philippines

The Philippines is rich in magnetite and hematite deposits, but many local plants struggle with high operational costs and inefficient grinding. A large-scale mining client in the Davao/Surigao region required a robust solution to process raw iron ore with high moisture content and high hardness (Bond Work Index). After technical consultation, Baichy Machinery provided a customized MQG 3245 Wet Type Grate Ball Mill to serve as the core grinding unit in their 2,500 TPD (Tons Per Day) beneficiation line.

Why the 3200x4500 Grate Ball Mill?

For heavy minerals like iron ore, the Wet Grate Type offers distinct advantages over overflow mills:

 ● Forced Discharge: The grate plate at the discharge end allows the ground slurry to exit quickly. This maintains a low pulp level, reducing "cushioning" and preventing the over-grinding of heavy iron particles.
 ● Higher Capacity: The 3200x4500 size provides a massive grinding volume, capable of handling large-scale feeding without clogging.
 ● Better Energy Efficiency: Equipped with double-row self-aligning roller bearings, the MQG 3245 reduces friction by 20-30% compared to traditional bush bearings.

Technical Performance Data

Advantages of Baichy ball mill

The success of this Philippines project was measured by three key metrics:

 ● Increased Recovery Rate: The precise grinding fineness (0.074mm) improved the magnetic separator's efficiency, increasing the iron concentrate grade from 58% to 64%.
 ● Reduced Maintenance: The heavy-duty ZGMn13 liners and automatic lubrication system extended the maintenance cycle to 10 months of continuous operation.
 ● Local Support: Baichy’s engineering team provided on-site installation and operator training in the Philippines, ensuring a seamless transition from commissioning to full-scale production.

The Baichy 3200x4500 Wet Grate Ball Mill has proven to be a game-changer for iron ore mining in the Philippines. By combining large-scale capacity with energy-saving technology, it offers the perfect balance of performance and profitability. Looking for a similar solution for your mine?
