The 1500 x 5700 ball mill, a medium-sized grinding machine, demonstrates wide applicability in the mineral processing industry. Its unique design of a 1.5-meter cylinder diameter and 5.7-meter length, combined with a reasonable rotational speed of 28 rpm, allows it to effectively process a variety of medium-hard ores. This wet overflow ball mill, supported by rolling bearings and driven by a 130 kW motor, is particularly suitable for mineral processing applications requiring fine grinding and continuous production. Its 12-ton steel ball loading capacity and 3.5-6 tons/hour processing capacity ensure grinding efficiency while also enabling adjustable discharge particle size (0.074-0.4 mm) to meet the fineness requirements of different ores. This structural design allows the equipment to withstand the impact of medium-hard ores while achieving a more uniform final particle size by extending the grinding time. This ball mill demonstrates excellent grinding performance for a variety of common ores:

Gold Ore: When wet grinding, efficient disaggregation can be achieved by adjusting the steel ball ratio (e.g., φ120mm:φ80mm:φ60mm = 3:4:3). This mill is particularly suitable for use with a spiral classifier to ensure sufficient recovery of gold particles.

Copper Ore: Chromium alloy steel balls (HRC58-62 hardness) effectively resist the abrasive effects of sulfide ores. The three-stage ball milling method provides both coarse and fine crushing, achieving a controlled particle size of 0.074-0.2mm for flotation processing.

Phosphorus Limestone: For medium-hardness materials, the equipment can extend the grinding time by reducing the drum speed (to 25 rpm), producing a more uniform fine powder product, meeting the chemical industry's requirements for ultrafine powders.

Iron Ore: The combined design of a stepped and corrugated liner enhances the impact crushing capability of magnetite. The centralized lubrication system (oil pressure 0.2-0.5 MPa) ensures stable operation under heavy loads.

Quartz: Wet grinding reduces powder flyaway. Adjusting the slurry concentration and counter-spiral blade settings effectively prevents overgrinding and improves the whiteness of the finished product.

This equipment also excels at grinding non-metallic ores such as limestone and calcite. Its 8.9 m³ effective volume and 15-ton pellet capacity balance throughput and energy consumption, making it particularly suitable for the continuous production needs of the building materials industry.
