1200×6000 ball mill technical parameters and industrial applications

The 1200 x 6000 ball mill, a medium-sized grinding machine with a cylinder diameter of 1.2 meters and a length of 6 meters, balances processing efficiency and energy consumption, making it suitable for processing minerals with a Mohs hardness of 7 or less. This model features a wet overflow structure, an effective volume of approximately 4.5 cubic meters, a ball loading capacity of 3.8 tons, and a 55kW motor (21 rpm), achieving an hourly production capacity of 7-10 tons. The feed particle size is controlled within 20 mm, and the output particle size can be adjusted to a fineness range of 0.074-0.4 mm (200-325 mesh) by adjusting the steel ball ratio. The equipment weighs approximately 12.3 tons and utilizes rolling bearings and rubber liners, reducing operating noise to below 85 decibels and achieving 15% energy savings compared to traditional sliding bearing models.

Core Application Scenarios

Non-metallic Mineral Processing: This equipment grinds materials such as kaolin and calcite to a fineness of d97 ≤ 20μm, meeting the filler whiteness (≥ 90%) and dispersibility requirements of the paper and coatings industries.

Metal Ore Pretreatment: Coarsely grinds low-grade ores such as copper, lead, and zinc, providing a slurry with a -200 mesh content of ≥ 70% for the flotation process, improving recovery by 8%-12%.

Building Material Preparation: In cement raw material grinding, this equipment, combined with a classifier, forms a closed-circuit system, achieving a specific surface area of 350m²/kg and increasing clinker strength by 5MPa.

Selection Recommendations: For high-hardness materials (such as quartz sand), it is recommended to replace the grinding wheel with chromium alloy steel balls (Ø 60-80mm) and reduce the rotational speed to 18 rpm, which can extend the liner life by 30%. For processing ores with a mud content greater than 15%, a pre-washing step in the spiral classifier is required to prevent "muddy grinding" in the mill.
