Gold Ore Mining Machine Ball Mill 1500x4500

The efficiency of gold recovery, whether by gravity, flotation, or leaching, is directly dependent on the fineness of the grind. The Ball Mill 1500x4500 is a cornerstone of this stage. The model name specifies its dimensions: a cylinder diameter of 1500 mm (1.5 meters) and a length of 4500 mm (4.5 meters). This size classifies it as an ideal solution for small to medium-scale mining operations or pilot plants, offering a perfect balance of capacity, power requirements, and footprint.

Its primary function is to receive crushed ore (typically less than 25mm) and use steel balls as grinding media to pulverize it into a fine slurry, often to the fineness of flour (below 200 mesh or 75 microns), to expose the gold particles for dissolution.

Key Features of the 1500x4500 Gold Ore Ball Mill

This ball mill is built for reliability, efficiency, and continuous operation in demanding conditions.

1. Robust and Durable Construction:

● Heavy-Duty Shell: The mill shell is constructed from high-tensile strength steel plate, designed to withstand constant abrasion, mechanical stress, and the weight of the grinding charge.

● Abrasion-Resistant Liners: The interior is fitted with replaceable liners made from high manganese steel or durable rubber. These protect the shell from wear and are engineered with a lifting profile to enhance the grinding action of the media.

2. Efficient Grinding Performance:

● Optimal Capacity: The 1500x4500 dimensions provide a substantial grinding chamber volume, making it capable of handling throughputs suitable for many small to medium-scale gold mines.

● Precise Grinding Media Control: The mill can be charged with steel balls of varying sizes. This mixture ensures efficient impact (for coarse particles) and abrasion (for fine particles), effectively breaking down the often hard and abrasive gold ore.

3. Reliable Drive and Operation:

● Girth Gear and Pinion Drive: This proven drive mechanism ensures smooth, powerful, and consistent rotation. It is designed for reliability and ease of maintenance.

● Precision Bearings: Equipped with large, self-aligning bearings that provide stable support for the rotating drum, reducing energy loss and preventing misalignment issues.

4. Designed for Process Integration:

● Feed and Discharge Design: The mill is designed with a trunnion or peripheral discharge system to allow for a continuous flow of ore in and slurry out, making it perfect for integration into a continuous processing circuit like a Carbon-in-Leach (CIL) plant.

● Safety and Control: Can be outfitted with temperature sensors on bearings and integrated with modern control systems to monitor power draw, providing data for optimizing feed rates and preventing overloads.

Real Case : Gold Beneficiation Plant in Ghana​

A small gold ore beneficiation plant in Kumasi processes low-grade alluvial gold ore (gold grade: 2–3 g/t) for local artisanal miners. They use the 1500x4500 mill as part of a cyanidation circuit:​
Result: The gold ore mill grinds 10 TPH of ore to 100μm (150 mesh), ensuring gold particles react fully with cyanide. Gold recovery rates stabilized at 88% (vs. inconsistent 70–80% with manual grinding), and the plant now processes 50% more ore daily.
