For lead-zinc ore crushing requirements, a combined configuration of a jaw crusher and an impact crusher is recommended to efficiently process medium-hard ore and meet a daily processing capacity of 500 tons. The jaw crusher, as the core equipment in the coarse crushing stage, has a simple structure, low maintenance costs, and can effectively crush large pieces of lead-zinc ore, providing uniform feed for subsequent operations. The impact crusher is suitable for medium and fine crushing, achieving selective crushing through impact principles to ensure cubic particle shapes, reduce needle-like and flaky content, and improve mineral separation efficiency. This combination not only simplifies the production process but also reduces energy consumption, aligning with the uneven particle size distribution characteristic of lead-zinc ore.

When selecting specific models, it is recommended to prioritize models with rolling bearing designs, as they have low starting current and long service life, making them suitable for high-load conditions. If the ore has a high mud content, a hydrocyclone can be added for classification to optimize the crushing effect. The actual configuration should be based on ore hardness test results to ensure long-term stable operation of the equipment and provide high-quality raw materials for subsequent flotation operations.
