Types of Jaw Crusher
Blake jaw crusher
This type of jaw crusher is the most commonly used in primary crushing applications. It employs a movable jaw to exert pressure on the rock or ore material, forcing it to break down into smaller pieces. The Blake jaw crusher has a fixed feed area and a variable discharge area.
Dodge jaw crusher
Similar to the Blake jaw crusher, the Dodge jaw crusher utilizes a movable jaw that is hinged at the bottom, allowing it to move back and forth in a swinging motion. It is also used for primary crushing and is known for its simplicity and reliability.
Universal jaw crusher
This type of jaw crusher combines the capabilities of both the Blake and Dodge crushers. It features a fixed jaw and a movable one that is driven by an eccentric shaft. The universal jaw crusher design allows for a higher crushing capacity and reduction ratio.
Single toggle jaw crusher
In this type of jaw crusher, the swing jaw is suspended on the eccentric shaft, which leads to a much more compact design than that of the double toggle jaw crusher. The single toggle jaw crusher is well-suited for applications where the primary objective is to reduce raw feed material to a manageable size.
Double toggle jaw crusher
This type of jaw crusher has two swinging jaws pivoted at the top and bottom of the moving jaw. The motion is generated by an eccentric arrangement, causing the moving jaw to move back and forth. Double toggle jaw crushers are often used for crushing hard and abrasive materials.
Overhead eccentric jaw crusher
In this design, the eccentric is mounted above the swinging jaw, which helps provide a more aggressive crushing action. This type of crusher is suitable for applications requiring high capacity and durability.
Mobile jaw crusher
These crushers are designed to be moved around and used in multiple locations as needed. They are commonly used in construction and mining sites for on-site crushing of materials.
Tracked jaw crusher
This is a type of mobile jaw crusher equipped with a track system for easy movement. It allows operators to navigate different terrains and access remote locations.
Hydraulic jaw crusher
These crushers use hydraulic systems to assist in adjusting the crusher settings and opening the crusher's chamber. This can help achieve desired product sizes and improve overall efficiency.
The working principle of a jaw crusher is that when the jaw rises, the angle between the fixed jaw and the moving jaw becomes larger, and the materials can be crushed. All jaw crushers feature two jaws: one of which is fixed while the other moves. The working principle of jaw crushers is based on the reciprocating movement of the movable jaw that compresses and crushes the rock or ore between itself and the fixed jaw, as the material enters the zone between the jaws.
The crushing process takes place when the feed material between the two jaws is compressed and crushed by the moving jaw. As the moving jaw moves away from the fixed jaw, the crushed material is discharged from the crusher at the bottom, with the size of the discharged material determined by the gap between the jaws.
The crushing action of a jaw crusher is caused by the motion of its swing jaw. The swing jaw moves back and forth by a cam or pitman mechanism, acting like a nutcracker or a class II lever. The volume or cavity between the two jaws is called the crushing chamber. The movement of the swing jaw can be quite small, since complete crushing is not performed in one stroke. The inertia required to crush the material is provided by a weighted flywheel that moves a shaft creating an eccentric motion that causes the closing of the gap.
Application of Jaw Crusher
Mining industry
One of the most common applications of jaw crushers is in the mining industry to crush large rocks into smaller pieces. They are used to crush ores such as iron, copper, gold, and silver. These machines are used to reduce the size of ore in preparation for further processing and refining. The crushing process helps to separate valuable minerals from the waste rock, making it easier to extract and process the valuable materials. Jaw crushers are also used in the coal industry, where they are used to crush coal before it is processed and transported to power plants or other end users.
Quarrying industry
Jaw crushers are used in the quarrying industry to crush large rocks into smaller pieces. They are used to crush stone, concrete, and asphalt for use in construction projects.
Construction industry
Jaw crushers are also commonly used in the construction industry, where they are used to crush materials such as concrete and asphalt for use in road construction and building projects. These machines are particularly useful for recycling materials, as they can break down old concrete and asphalt into smaller pieces that can be reused in new construction projects.
Recycling industry
Another application field for jaw crushers is in the recycling industry to crush concrete, asphalt, and other construction materials. These machines are used to crush a wide range of materials, including glass, plastic, metal, and paper, for use in the production of new products. Jaw crushers are particularly effective at breaking down materials that are difficult to recycle, such as electronic waste and construction waste.
Crusher body
The design of the crusher body ensures that it's capable of withstanding bending and fracturing stress even when crushing the hardest of materials.
Pitman
This refers to the swinging jaw and achieves the reciprocating movement through the eccentric motion of the main flywheel hhaft which creates an enormous force in each stroke.
Fixed jaw
Directly opposite the swinging jaw which is attached to pitman, both swinging and fixed jaw and normally made of manganese which is a very hard metal. Both jaws when worn can be flipped to extend their life span.
Flywheel
The flywheel is the heart of the rotational energy needed to feed into the eccentric shaft to maintain rotational inertia as the jaw crushes material.
Jaw crusher bearings
Normally there are four bearings on the eccentric shaft, two on each side of the crusher body supporting the main shaft and two at the end of the pitman. The bearings are normally tapered roller bearings.
Toggle plate
The bottom of pitman is supported by the toggle plate, which allows the bottom of the pitman to move up and down with the motion of the eccentric shaft, also serves as a safety failsafe for the whole jaw to prevent further damage should any uncrushable material enter the crushing jaws, designed to bend or even break if necessary.
Toggle rams, spring & screw rod
Without these the bottom of the pitman would just flop around, these ensure the pitman is firmly fixed to the toggle plate. The toggle seats are fixed points where the toggle plate contacts the pitman.
CSS, (closed side settings)
Crushed material size is achieved by adjusting the opening at the bottom of the jaws, different jaw crusher models can have shim plates, and others have wedges moved by hydraulic rams.
Cheek plates
These are wear plates that protect the inside of the crusher body during the material being crushed.
Power source
Crushers are powered by either a diesel engine, diesel hybrid, or fully electric depending on model.
