This crusher features a double movable jaw with an upper and lower rotationally symmetrical "V"-shaped structure. Most jaw crushers on the market today are compound swing jaw crushers. The main disadvantage of this type is that as the material moves toward the discharge port, it receives progressively less crushing force. Near the discharge port, the material is almost impossible to crush effectively.
Crushing efficiency depends on the displacement distance in the direction of force. According to the physical formula "W = F × L," work (W) is equal to force (F) multiplied by distance (L). This jaw crusher addresses the issue of insufficient crushing force at the discharge end by optimizing its structure. The inverted movable jaw provides a full crushing stroke at the discharge end, resulting in a significantly larger crushing ratio. While common compound swing jaw crushers have a crushing ratio of 3 to 5 times, the dual-core jaw crusher can achieve a crushing ratio of up to 15 times. This enables the machine to handle the entire process from raw material to aggregate in a single step. For example, it can crush raw materials from 500mm down to 40mm, achieving a production capacity of nearly 100 tons per hour.
