Portable Mobile Crusher Quarry Rock Jaw Crusher Breaker Machine

Working Principle:
The working principle of TONTEN Machinery jaw crusher machine is very straightforward, with its core being extrusion and crushing.
Motor Drive: The electric motor drives the pulley via a V-belt.
Eccentric Shaft Rotation: The pulley rotates the eccentric shaft (or main shaft).
Moving Jaw: The rotation of the eccentric shaft causes the connected movable jaw to oscillate in a complex motion. This motion traces a similar elliptical path: When the movable jaw approaches the fixed jaw plate, it squeezes and rubs the material between the two jaw plates, crushing it. When the movable jaw leaves the fixed jaw plate, the crushed material is discharged from the discharge port under its own weight.
Reciprocating Cycle: The motor continuously runs, causing the movable jaw to perform a continuous reciprocating motion, achieving continuous feeding, crushing, and discharge operations.

Structural Features:
1. Frame: The framework of the jaw crusher, requiring extremely high strength and rigidity. It is typically welded from high-quality steel plates or cast steel.
2. Moving and Fixed Jaw: The moving jaw is the movable crushing component, while the fixed jaw is stationary. They are mounted with jaw plates (also called tooth plates). These are the components that come into direct contact with the material and are subject to wear. They are typically made of wear-resistant materials such as high-manganese steel.
3. Eccentric Shaft: The core transmission component. The eccentric portion of the jaw crusher drives the moving jaw. It is the part that bears the greatest stress and demands the highest process standards in the entire equipment.
4. Jaw Plates: These are divided into moving and fixed jaw plates. Their surfaces are typically serrated to enhance crushing efficiency. The degree of wear on the jaw plates determines the equipment's maintenance cycle.
5. Toggle Plate: Also known as the thrust plate, it serves two important functions: transmitting force and acting as a safety device. When uncrushable material (such as iron) enters the crushing chamber, the toggle plate will break first due to exceeding the designed stress, thus protecting core components such as the eccentric shaft and frame from damage.

6. Adjustment Device: Used to adjust the size of the jaw crusher's discharge opening to control the discharge particle size. Wedge or shim adjustment is typically used.
7. Flywheel: Installed at both ends of the eccentric shaft. The flywheel stores energy during the idle stroke (when the movable jaw moves away from the fixed jaw) and releases that energy during the working stroke (when squeezing material), ensuring smoother machine operation.
8. Lubrication System: Mainly provides lubrication for key friction pairs, such as the eccentric shaft and bearings. Common methods include manual grease lubrication and centralized automatic lubrication.
