An aggregate jaw crusher works by using a compressive force to break down larger rocks into smaller pieces. Here’s a general overview of how it operates:
1. Feed material: The raw material to be crushed is fed into the jaw crusher’s chamber from the top through a vibrating grizzly feeder or a conveyor. Typically the raw material will be virgin quarried stone or waste from construction and demolition waste or utility highway arisings.
2. Crushing chamber: Inside the chamber, there are two jaws – a fixed jaw and a movable jaw. The movable jaw is attached to a swinging mechanism that moves back and forth, exerting pressure on the material such as stone, bricks, concrete and asphalt.
3. Crushing action: As the movable jaw moves towards the fixed jaw, the material is crushed between the two jaws. This process generates a compressive force that breaks the material into smaller pieces. A robust magnet is also conveniently located after the crushing jaws before the discharge conveyor to collect any metal such as reinforced bars also known as rebar. This metal is then discharged into a skip and further processed and recycled.
4. Discharge: Once the material reaches the desired size, it exits the crushing chamber through the bottom opening. The size of the final product is determined by the gap between the jaws, which can be adjusted to control the size of the output. Currently our 6F5 recycled aggregate at Mayo Stone is also known as ‘crush’ is 75mm down to dust or 0-75mm.
5. Eccentric shaft: The movement of the movable jaw is driven by an eccentric shaft that is powered by a motor. This eccentric motion enables the jaw crusher to exert the necessary force for crushing the material effectively.
6. Safety features: Most modern jaw crushers are equipped with safety features such as overload protection and a toggle plate that protects the crusher in case of uncrushable material entering the chamber.
Overall, the aggregate jaw crusher is a robust machine designed to efficiently crush hard and abrasive materials in various aggregate processing applications, such as mining, quarrying, and recycling.
