Performance parameters and applications of the 1830 overflow ball mill

The 1830 overflow ball mill, a core piece of equipment in the mineral processing and building materials industries, demonstrates significant advantages in fine grinding due to its structural design and process adaptability. Its performance parameters are centered on high-efficiency processing capacity: the combination of a 1830 mm diameter and 4500 mm length provides an effective volume of approximately 12.5 cubic meters, supporting continuous large-scale production; the ball loading is typically 17.5 tons, combined with an optimized rotation speed of 24.5 rpm, ensuring thorough grinding of the ore within the mill; driven by a 130 kW motor, a single unit can process up to 28 tons per day, with a stable output particle size in the 0.074-0.4 mm range, meeting high fineness requirements. This equipment employs an overflow discharge design, extending material residence time through natural slurry flow, significantly improving grinding uniformity while simplifying the structure and reducing maintenance difficulty.

Its applications cover three major industries: in metal beneficiation, it is used for the fine crushing and classification of materials such as iron ore and copper ore, providing raw materials with qualified particle sizes for subsequent flotation processes; in building materials production, it grinds raw materials in the cement and ceramics industries to ensure consistent product fineness; and in chemical raw material processing, it processes fertilizers, non-metallic mineral powders, etc., to meet the demand for high-purity fine powder. Its versatility makes it particularly suitable for the second stage of a two-stage grinding process. By adjusting the ball loading and rotation speed parameters, it can flexibly adapt to different ore hardness and process requirements, becoming a key piece of equipment for improving efficiency in large and medium-sized beneficiation plants.
