Ball Mill

Ball mill is a cylindrical grinding equipment widely used in the field of ore milling, also known as ball mill grinding machine or ball grinder. As the drum rotates, the steel balls inside ‌cascade and roll‌, subjecting the material to impact and grinding. Ball mill machines are key equipment for crushing materials after they have been crushed.

As an industrial ball mill manufacturer, LDHB supply a wide range of wet ball mills and dry grinding ball mills, which are widely used in cement plants, gold processing plants, coal washing plants.

Ball Mill Working Principle

A ball mill grinds materials through the movement of grinding media (including steel balls, steel rods, pebbles, gravel, ceramic balls, etc.) inside its rotating drum.

As the ball mill equipment rotates, the grinding media adhere to the drum’s inner lining under the combined effects of centrifugal force and friction. The media are carried upward with the drum until they reach a certain height, after which they fall freely. During the descent, the grinding media impact the material at the bottom like projectiles, breaking it apart.

Grinding media balls also slide and roll within the ball grinder drum, further grinding the material into fine powder. Since new material is continuously fed into the ball mill machine, a material level difference exists between the feed and discharge ends, which forces the material to flow. Additionally, the axial thrust generated by the falling grinding media further drives the material flow.

LDHB Ball Mill Features

1. High-efficiency Grinding Performance

The ball mill machine achieves rapid fine grinding of materials such as ore, cement, and construction waste through the continuous rotation and friction of grinding media (steel balls, steel forgings, ceramic balls, etc.) within its drum. This process significantly enhances chemical reaction rates, boosting production efficiency by over 30% compared to traditional methods, making it particularly suitable for industrial scenarios with high-capacity demands.

2. Robust and Durable Structure

Utilizing high-chromium alloy steel balls and precision casting technology, the core components exhibit a 50% increase in wear resistance. The grinding machine’s design eliminates the need for complex auxiliary systems, supporting 24/7 continuous operation. With a failure rate below industry averages, maintenance costs are reduced by 40% compared to similar grinding mill equipment.

3. Easy Operation

The ball mill is simple to operate, low maintenance and management costs, making it suitable for mining enterprises of varying scales.

4. Full Environmental Adaptability

Certified to ISO9001 standards, it operates stably within temperature ranges from -30°C to 50°C and at altitudes up to 5000 meters. For high-humidity environments, an anti-rust coating is applied, ensuring over 98% ball milling availability even in extreme climates like tropical rainforests and deserts.

5. Precise Particle Size Control

LDHB ball mill machines support stepless adjustment within a particle size range of 0.074mm to 0.5mm. By adjusting parameters such as steel ball ratio (Φ20mm-Φ120mm) and filling rate (30%-45%), particle size tolerance can be controlled to ±0.02mm, meeting stringent standards in industries like cement and metal ore processing.
