Double jaw crushers are heavy-duty machines that are designed to crush large-sized materials into smaller pieces. These crushers consist of two jaws, one fixed and the other movable, mounted on an eccentric shaft. The jaws are positioned in a V-shape, with the top opening wider than the bottom. As the material passes through the crushing chamber, it is crushed between the two jaws and released at the bottom.

The double jaw crusher parts are made up of several components that work together to ensure smooth and efficient operation. Some of the main components of the double jaw crusher include:

1. Fixed Jaw Plate: The fixed jaw plate is a stationary plate that is mounted on the front frame of the crusher. It acts as a platform for the material to be crushed against and provides support for the movable jaw plates. The fixed jaw plate is made from high-quality steel and is designed to last for a long time.

2. Movable Jaw Plate: The movable jaw plate is the plate that moves back and forth to crush the materials against the fixed jaw plate. The plate is mounted on an eccentric shaft, which is driven by a motor. The movement of the plate is controlled by the motor, which ensures that the material is crushed evenly.

3. Flywheel: The flywheel is a heavy wheel that is mounted on the rear end of the eccentric shaft. It helps to balance the inertia of the eccentric shaft and provides a smooth operation of the crusher. The flywheel is made from high-quality steel and is designed to absorb shock and provide stability during operation.

4. Bearings: The bearings of the double jaw crusher are located on both ends of the eccentric shaft. They help to support the shaft and the movable jaw plates, reducing friction and wear. The bearings are made from high-quality steel and are designed to last for a long time.

5. Wedge Plate: The wedge plate is a small plate that is located on the top of the movable jaw plate. It helps to adjust the gap between the fixed and movable jaw plates. The gap can be adjusted to ensure that the material is crushed to the desired size.

6. Tension Rod: The tension rod is a component that holds the movable jaw plate in place. It is attached to the rear end of the frame and helps to adjust the position of the movable jaw plate.

To summarize, the double jaw crusher is a heavy-duty machine that is used to crush large-sized materials into smaller pieces. The machine consists of several components that work together to ensure smooth and efficient operation. The main components of the crusher include the fixed and movable jaw plates, flywheel, bearings, wedge plate, and tension rod. All these parts are made from high-quality steel and are designed to last for a long time. Proper maintenance and lubrication are essential to ensure the longevity of the crusher.
