Energy Saving Ball mill for Lithium ore Spodumene

Energy Saving Ball mill for Lithium ore Spodumene

1.Product Introduction

The Energy-Saving Ball Mill for Lithium Ore (Spodumene) is a high-efficiency, energy-saving grinding equipment specifically designed for the pulverization of lithium-bearing minerals such as spodumene. It is extensively utilized in lithium extraction from new energy minerals and grinding operations within mineral processing plants. This equipment is characterized by low energy consumption, high production capacity, and exceptional operational stability.

2.Application

Considering the high hardness of spodumene (Mohs hardness 6.5–7) and its fine dissociation particle size, our specialized energy-saving ball mills are engineered with the following characteristic parameters:

• Max Feeding Size: ≤25mm

• Discharge Size: Down to 0.065mm (approx. 200+ mesh)

• Motor Power: Configurable within the 15–500kW range

• Ball Load: Approximately 180 tons, supporting both dry and wet grinding modes

• Discharge Method: Supports dual modes (Overflow and Grate type) to adapt to various mineral processing requirements

3.Working Principle

The Energy-Saving Ball Mill is a horizontal cylindrical rotating device driven by an external gear transmission. The cylinder is internally loaded with steel balls as grinding media. After materials enter the cylinder through the feeding inlet, they are carried up to a certain height by the liners as the cylinder rotates, then fall to create high-impact and grinding forces. This process achieves the fine or ultra-fine grinding of ores such as spodumene.

Based on the discharge method and operational requirements, it is categorized as follows:

• By Discharge Method: Available in Overflow Type and Grate Type.

• By Operational Mode: Available in Dry Grinding and Wet Grinding to meet different process flow requirements.

4.Advantages

 Significant Energy Savings & Consumption Reduction

• Higher Efficiency: Total power consumption is reduced by over 20% compared to traditional ball mills, with motor power requirements decreased by 15%–25%, significantly optimizing unit product energy costs.

• Advanced Bearings: Large-scale rolling bearings replace sliding bearings, resulting in lower starting current and reduced frictional power loss, avoiding impact on the electrical grid.

• Eco-friendly Lubrication: Utilizes grease lubrication instead of oil, reducing lubricant consumption by 70% and cooling water by 90%, ensuring zero oil and heavy metal pollution.

 High-Adaptability Structural Design

• Spodumene-Optimized: To handle the high hardness of spodumene (Mohs 6.5–7), internal liners are available in ceramic, rubber, or manganese steel, increasing wear resistance by 3–5 times.

• Dual-Mode Grinding: Supports both dry and wet grinding. Discharge fineness can be precisely controlled between 0.02–0.075mm (200–700 mesh), meeting the specific requirements for mineral liberation in flotation processes.

• Customizable Configuration: Tailored grinding media ratios and Grate/Overflow discharge designs adapt to various processing flows (e.g., grinding after sulfuric acid roasting).

Extended Service Life & Low Maintenance Costs

• Durable Main Bearings: The main bearings are designed for a 10-year service life without replacement, drastically reducing downtime for overhauls.

• Modular Construction: Features a modular, quick-disassembly structure, making the replacement of liners and steel balls convenient and reducing maintenance man-hours by over 40%.

• Intelligent Monitoring: Equipped with automated lubrication and temperature monitoring systems, reducing the need for manual intervention and enhancing stability during continuous operations.
