Jaw crushers are important equipment in mining, construction, and aggregate industries. These machines are responsible for producing large minerals into smaller particles. Their durability in constant high pressure is a testament to the quality of their every component.
Many elements make up these versatile tools that’s why understanding them is pivotal in ensuring each part operates smoothly. It also helps you to further grasp the capabilities and potential of the equipment.
In this article, we dive into the parts of a jaw crusher machine. Whether you are in material processing or equipment maintenance, this is your basic guide to its essential components.
Crusher Body
The crusher body is the overall encasement designed to resist high pressures from the process of crushing hard materials. It is often constructed with durable materials to ensure smooth operations. The body can be made from steel, cast iron, carbon steel, manganese steel, or Hardox or AR steel.
This part may also be produced from composite materials like various alloys. Wear-resistant coatings are applied to enhance its longevity.
Rocker
The rocker supports the upper and lower parts of the equipment. With this connection, it is responsible for the essential function of the jaw. This means that it impacts the movement of this tool.
This part connects the flywheel and eccentric shaft of the upper body to the lower parts. The lower parts are the toggle plates, toggle seats, and tension rods. As the main moving part of the crusher, it enables the smooth movement of the jaw sides.
Jaw Plate
The jaw plate is made out of manganese. It is the inward-facing side of a rocker. This component covers the previous part with hard metal.
Also known as jaw dies, it is made up of moveable and fixed jaws. These are called swing or stationary plates. This part often determines the capability of the equipment. To ensure the safety of operations, it is important to maintain its quality.
Eccentric Shaft
The eccentric shaft extends the entire length of the rocker. One end of the shaft is connected to the pulley, while the other end is attached to the flywheel. This shaft is crucial to the rocker’s operation, as it generates oscillating eccentricity.
Due to the high forces exerted on this component, particularly bending torque, it is typically constructed from high-carbon steel to ensure durability and performance.
Flywheel
Two critical roles are essential in the operation of a jaw crusher, both of which are performed by the flywheel located at either end of the shaft.
The first role of the flywheel is to balance the weight of the grooved wheels, thereby supporting the function of the multiple V-belt grooves. The second role is integral to the overall crusher operation. The flywheel stores rotational energy, which is then transferred to the crusher material once sufficient energy has been accumulated.
Jaw Crusher Bearings
The bearings can be seen on each side of the jaw frame. There are two on each side, supporting the shaft and the ends of the rocker. They are rollers developed with various lubrications for ease of function.
Proper lubrication or oiling for these components is essential. It is a maintenance routine that strengthens its performance in high temperatures. The practice will help reduce the risk of major bearing failure or damage.
Toggle Plates
At the bottom of the rocker, there is a curved piece of metal that props the component up. This is the toggle plate. It is adjustable, allowing the rocker to move up or down. The support for movement is essential due to the constant motion of the eccentric shaft.
One of the functions of this part is to protect the equipment from damage. It is a fuse that will bend and break to prevent issues.
Cheek Plates
The crusher’s body is covered with cheek plates. Located on the sides of the general body, it is the liner plate between the fixed and moveable jaw plates. The main function of this part is to protect the crusher frame.
The cheek plates are made from high-strength steel material. Manganese is often the top choice, enhancing the wear resistance of the part.
