What Is Jaw Crusher Machine?

A main crusher used in mines, quarries, and other industrial settings is a jaw crusher equipment. But what is jaw crusher machine? It functions by crushing materials between two enormous, one stationary and the other moving, jaws utilizing compressive force. The moving jaw is supported by a pitman that oscillates, or “swings back and forth,” compressing the material against the stationary jaw in order to crush it. Depending on the machine’s capacity, the operation reduces the size of the material being crushed, which can be anything from tiny rocks to massive boulders. In the mining and aggregates industries, as well as in the construction and recycling industries, jaw crushers are frequently utilized.

Practical types of jaw crushers

Several types and sizes of jaw crushers are available to accommodate diverse crushing needs. Following are some useful jaw crusher machine types:

• 1. Portable Jaw Crusher: Portable jaw crushers may be moved simply between job sites since they are installed on trailers or chassis. On construction and demolition sites, it is frequently employed.
• 2. Stationary Jaw Crusher: The stationary jaw crusher is ideal for primary crushing in quarries and mines since it is put in a fixed location.
• 3. Mobile Jaw Crusher: Jaw crushers of this type can be moved easily between job sites because they are mounted on mobile chassis. It is frequently utilized in quarrying and mining activities as well as building and demolition sites.
• 4. Mini Jaw Crusher: This type of jaw crusher is suitable for use in laboratories or for small-scale crushing operations because of its compact size.
• 5. Industrial Jaw Crusher: This kind of jaw crusher is utilized in mining and quarrying for heavy-duty crushing applications.
• 6. Recycling Jaw Crusher: Concrete and asphalt materials can be crushed and recycled using a jaw crusher that is specifically made for that purpose.
• 7. Impact Jaw Crusher: Impact jaw crushers are used often in the construction and demolition sectors to crush materials using impact force.
• 8. Tracked Jaw Crusher: Jaw crusher that is mounted on a tracked chassis and is ideal for use in a variety of applications, including mining and construction, is known as a tracked jaw crusher.

Applicable materials for jaw crusher machines

Many different types of materials can be crushed using jaw crushers, including:

Materials like granite, basalt, and quartz are tough and abrasive.
Sandstone and limestone are examples of soft, less abrasive materials.
Waste from construction and demolition
Asphalt and concrete
Metals, both ferrous and non-ferrous
Coal, iron ore, gold ore, copper ore, and other ores and minerals

The hardness, abrasiveness, size, and shape of the material are all crucial factors to take into account when choosing materials for jaw crusher machines. Stronger and more resilient materials, like manganese steel or high chrome iron, will be needed for the jaw plates and liners for processing harder and more abrasive materials. Less wear-resistant materials, like cast iron or carbon steel, can be used in the processing of softer materials.

The material’s size and shape should also be taken into account because larger and more atypically formed materials may need larger feed holes and more powerful crushing pressures than smaller, more consistently sized ones. The choice of material for a jaw crusher will ultimately depend on the application in question as well as the required output size and shape.

The internal structure of the jaw crusher

A jaw crusher’s interior structure is made up of a number of components that work together to produce the appropriate crushing outcome. The primary parts are broken down as follows:

• 1. Frame: All other parts of the jaw crusher are supported by the frame, which is built of high-strength steel.
• 2. Eccentric Shaft: Eccentric Shaft: The eccentric shaft is a key rotational component that reciprocatesly moves the jaw plate back and forth.
• 3. Jaw Plate: The jaw plate, which is the jaw crusher’s major wear-resistant component, is fastened to the jaw bed by bolts and wedge-shaped iron blocks. It is constructed from high-manganese steel or another durable material.
• 4. Toggle Plate: The toggle plate is utilized to support the jaw plate’s bottom while also allowing it to slide back and forth. It is made of steel or cast iron.
• 5. Flywheel: During the crushing operation, the flywheel stores energy that is then released during the idle stroke. It is made of steel or cast iron.
• 6. Tension Rods: The tension rods are used to maintain the correct tension of the toggle plate and to modify the size of the discharge hole.
• 7. Bearings: The eccentric shaft is supported by bearings, which also serve to lower friction while in use. High-strength alloy steel is often used to make them.

Overall, a jaw crusher’s internal structure is built to deliver a dependable and effective crushing operation, with each component functioning in concert to produce the intended crushing outcome.

Wearing parts of jaw crusher machines

Important pieces of a jaw crusher machine that go through wear and tear when crushing are called wearing parts. The primary components of a jaw crusher machine that wear out include:

• 1. Jaw plates: The primary elements that smash the material put into the crusher are the jaw plates. Manganese steel, a high-strength material that can survive the crushing pressures produced by the machine, is commonly used to make jaw plates. To keep the machine operating efficiently, jaw plates must be replaced as they deteriorate over time.
• 2. Toggle plate: The toggle plate is a little part that joins the crusher’s moveable jaw to the rest of the machine. It makes sure that the jaw plates stay in the correct alignment and aids in transmitting the crushing forces produced by the machine. Toggle plates can deteriorate over time and need to be changed, just as the jaw plates.
• 3. Bearings: Two bearings are located at the back of the swing jaw of jaw crushers. During the crushing process, these bearings are subjected to tremendous loads and friction, which can cause them to wear out or fail. These bearings must be lubricated and maintained regularly to last a long time.
• 4. Eccentric shaft: This essential part is what propels the crusher’s swing jaw. Due to the enormous stresses it experiences while in use, the eccentric shaft may eventually acquire cracks or other flaws that will make it unable to function. These problems can be avoided with regular eccentric shaft maintenance and inspection.
• 5. Springs: To provide pressure on the material being crushed, jaw crushers use springs. These springs may break or lose tension over time, which could impair the machine’s functionality. The effective operation of the crusher can be ensured by routinely checking and replacing these springs.
