How Does a Double Toggle Jaw Crusher Operate? (With Animation)

A double toggle jaw crusher operates using a mechanism with two toggle plates that help to control the movement of the jaw, allowing it to crush materials effectively. Here’s a detailed breakdown of its operation, along with an explanation of how an animation would depict it:
1. Main Components:
- Fixed Jaw: The stationary surface against which the material is crushed.
- Swing Jaw: The movable jaw that exerts force on the material to break it.
- Toggle Plates: Two toggle plates connect the swing jaw to the rest of the crusher frame. These plates apply force and amplify the motion of the swing jaw.
- Pitman: The component that drives the movement of the swing jaw, connected to the eccentric shaft.
- Eccentric Shaft: A shaft with an offset center that rotates to cause an oscillating motion.
2. Arbetsprincip:
- In a double toggle jaw crusher, the eccentric shaft causes the swing jaw to move in a reciprocating motion.
- The toggle plates alternately compress the swing jaw against the fixed jaw, creating a crushing action.
- When the swing jaw moves forward, it crushes the material; when it retracts, the crushed material moves downward, allowing for continuous crushing and discharge through the bottom of the machine.
- The movement is more complex compared to a single-toggle jaw crusher, resulting in a more precise crushing action and higher load distribution.
3. Animation Explanation:
- In an animation, you would see the eccentric shaft rotating, which sets the pitman in motion.
- This motion is transferred to the swing jaw via the toggle plates, causing it to move back and forth against the fixed jaw.
- The material between the jaws is compressed during the forward motion of the swing jaw and released as it moves back.
- Broken material drops through the bottom opening during the backward motion.
- You’d also notice how the toggle plates act as a safety mechanism; they break if the load exceeds the crusher’s capacity, preventing damage to other parts of the machine.
4. Key Advantages of Double Toggle Jaw Crusher:
- Efficient crushing with higher capacity due to its more robust crushing action.
- Better durability since the motion is evenly distributed across toggle plates, minimizing wear.
- Safety feature: The toggle plates act as built-in safeguards against overloading.
By pairing the visual animation of moving components with the above explanation, the operation of a double toggle jaw crusher can be well understood. Animations typically highlight the motion paths of the swing jaw, the interaction of toggle plates, and the material flow for better clarity.
