Jaw crusher mainly crushes ores with large size or medium and high hardness. It has the characteristics of simple structure, high crushing efficiency and easy maintenance. It has two jaws, fixed and movable. Large pieces of material are compressed between the two jaws to become crushed stone or easy-to-handle size.
Types of Jaw Crushers / Jaw Crusher Types
There are many types of jaw crushers, each designed to meet specific crushing requirements. The main types of jaw crushers include:
Single Toggle Jaw Crusher
Single toggle jaw crusheris a type of crusher commonly used in the mining and aggregate industries. It consists of a single moving jaw that operates in an elliptical motion to crush the material between itself and the fixed jaw. This type of jaw crusher is commonly used in the primary crushing stage of various materials, such as rocks, bijih, and construction aggregates.

Lower speeds
Advantages and disadvantages comparison
Keuntungan
Detailed description
High reduction ratio
Double toggle jaw crushers have a higher reduction ratio, crushing tougher materials and reducing larger feed sizes more efficiently
Daya tahan
Because the load is distributed over more parts, this type of crusher tends to be more durable and requires less frequent maintenance
It is more efficient at handling hard and abrasive materials
Disadvantages
Detailed description
Higher initial cost
The double toggle mechanism makes this type of crusher more complex, with more moving parts and a higher initial cost
Lower throughput
The crusher operates at a lower speed compared to a single toggle jaw crusher, resulting in lower throughput
Higher maintenance costs
Due to the higher number of components and complex design, maintenance costs can be higher compared to a single toggle jaw

Industrial applications
Compound jaw crusher
The compound jaw crusher is a versatile, efficient machine that combines the best features of single and double toggle crushers. It is particularly suitable for handling tough materials with strong crushing capacity. Daya tahannya, efficiency, and ability to handle a wide range of materials make it a valuable choice in the mining, construction, and aggregate production industries. Namun, the more complex design and higher initial cost may be factors to consider when choosing this type of crusher.

Functional description
Fixed Jaw
The fixed jaw that remains in place while the moving jaw crushes the material
Swinging Jaw
The moving jaw crushes the material against the fixed jaw. In a compound jaw crusher, the movement of the movable jaw can be more complex than a standard single toggle design
Toggle Plates
They connect the movable jaw to the connecting rod and allow for bidirectional movement
Connecting Rod
The shaft that transmits the mechanical force to move the movable jaw
Flywheel
A large wheel that stores and releases energy to assist the movement of the jaws
Frame
The external structure that holds all components in place and supports the crusher
Main Features
Combination of single and double toggle mechanism

High Crushing Capacity
Wider Material Handling Capability
Advantages and disadvantages comparison
Keuntungan
Detailed description
Efficient
The compound jaw crusher combines the advantages of single and double toggle mechanisms, making it more efficient in crushing hard materials
Keserbagunaan
It can handle both hard and soft materials and is capable of handling larger feed sizes, making it ideal for primary crushing in various industries
Durable and long-lasting
The design ensures a longer service life, which reduces maintenance costs
Better material distribution
The design reduces stress on individual components, resulting in more even material distribution and more uniform product output
Disadvantages
Detailed description
Complex design and more expensive to manufacture
The combined mechanism of the compound jaw crusher makes the machine more complex and more expensive to manufacture than the simpler single toggle crusher
More maintenance requirements
While it can reduce wear on some components, the increased number of components can lead to more maintenance requirements
Higher initial cost
Due to the more complex design, the initial investment of a compound jaw crusher can be higher than that of a simpler jaw crusher

Blake Jaw Crusher
Blake jaw crusheris a jaw crusher with the movable jaw hinged at the top. It was invented by Eli Whitney Blake in 1858 and has become one of the most widely used jaw crushers for crushing a variety of materials, especially in the primary crushing stage.
Types
Single Toggle Plate Blake Jaw Crusher: The active jaw is driven by a single toggle plate, which reduces friction and wear.
Double Toggle Plate Blake Jaw Crusher: This type uses two toggle plates, which provides greater crushing force, making it suitable for more severe applications.
Advantages and disadvantages comparison
Keuntungan
Disadvantages
High output and large feed volume
Large size and weight compared to other types of jaw crushers
Simple design and easy maintenance
Moving parts are prone to wear and require regular maintenance
High reduction ratio, suitable for large-scale crushing
Aplikasi
It is commonly used in the mining, quarrying and recycling industries to crush hard, abrasive materials such as ore, rock and concrete.
