Jaw Crusher

What is a jaw crusher?

A jaw crusher is a primary crushing machine used to reduce large rocks, ores and construction materials into smaller pieces.

It is widely used in mining, quarrying, aggregate production and recycling because it can handle hard, abrasive and bulky feed material.

As the first machine in a crushing line, its main purpose is to achieve high reduction ratios and prepare materials for further processing.

Materials commonly processed by jaw crushers include:

• Hard rocks: Granite, basalt, quartz and sandstone.
• Ores and minerals: Iron ore, gold ore, copper ore, limestone and river gravel.
• Construction waste: Concrete, reinforced concrete, asphalt and brick.

They are especially effective when the feed material is large, hard or irregular in shape.

How does a jaw crusher work?

A jaw crusher works by compressing material between two jaw plates:

Raw material enters the crushing chamber from the top, where the movable jaw moves toward the fixed jaw to compress and crush the material into smaller pieces. As the movable jaw moves away, the crushed material drops lower in the chamber.

The process repeats until the material is small enough to exit through the discharge opening. The size of the final product is controlled mainly by the closed side setting (CSS), which is the smallest gap between the two jaw plates.

Popular types of jaw crushers

Since the first jaw crusher was invented by Eli Whitney Blake in 1858, the design has continued to evolve for different crushing applications.

Based on decades of engineering experience, FTM Machinery offers five proven jaw crusher series, each built for a specific production requirement—from small quarries to high-capacity mining operations.

Main parts of the jaw crusher

A jaw crusher consists of several main parts that work together to provide crushing functionality.

The basic structure of a jaw crusher includes the fixed jaw plate, movable jaw plate, toggle plate, eccentric shaft, flywheel, etc.

Jaw plates, including one fixed plate and one movable plate, are the main wear parts of a jaw crusher. Regular inspection and timely replacement help maintain crushing efficiency and extend service life. Learn How to Choose the Right Jaw Plate.

Other part names and functions of the jaw crusher:

• Frame: Keep the machine in place and protect it to reduce abrasion.
• Bearing: Support the rotating components of the jaw crusher, such as the eccentric shaft and flywheel.
• Tension rod: Control the movement of the movable jaw and prevent it impact the front main frame in any situation.
• Adjusting set: Change the discharging opening size of the crusher to satisfy different customers' requirements.
