Crushing equipment is a key component in the mining, construction, and industrial processing industries, capable of crushing various materials into specific particle sizes. Based on the force applied, it can be categorized as either extrusion or impact crushers. Extrusion crushers, such as jaw, gyratory, cone, and roller crushers, crush materials by squeezing them between fixed and moving surfaces. They are suitable for hard materials like granite, producing less dust but more flake-like particles. Impact crushers, such as hammer and impact crushers, use high-speed rotating components to impact the material, causing high-frequency collision and shearing to pulverize the particles. They are commonly used for low- to medium-hardness materials, achieving high crushing ratios and fine particle shape.
Based on the operation stage, crushing equipment can be categorized as coarse, medium, fine, and sand-making and shaping equipment. Jaw or gyratory crushers are commonly used for coarse crushing, offering large feed openings and high processing capacity. Cone and impact crushers are used for medium and fine crushing. The former is suitable for hard rock, while the latter is used for low- to medium-hardness materials and produces fine particle shape. Vertical shaft impact crushers are often used for sand-making and shaping, offering high efficiency and controllable gradation. These equipments are matched with feeding, screening and conveying equipment to form a complete production line to meet the material processing needs of different industries.
