Introduction
Since its invention by Eli Whitney Blake in 1858, the jaw crusher has become a core piece of equipment in the global mining, quarrying, and construction waste recycling industries. SUHMAN, inheriting the tradition of Chinese military manufacturing and combining it with advanced Austrian technology, provides efficient and reliable mobile crushing solutions for modern mines.
This guide will provide an in-depth analysis of the working principles, selection methods, and technical parameters of jaw crushers, helping you make informed equipment purchasing decisions.
I. History and Development of Crushing Technology
1.1 From Manual Crushing to Mechanization
The earliest method of crushing was to repeatedly hammer large stones onto rocks placed on an anvil, with the product transported by manpower or livestock. This labor-intensive operation continued until the mid-19th century.
The Industrial Revolution brought about significant changes:
- 1858: Eli Whitney Blake invented the first jaw crusher
- 1906: McLanahan introduced the first modern eccentric jaw crusher
- Late 20th Century: Tracked mobile crushers were invented
- 21st Century: Intelligent and hydraulic systems became mainstream
1.2 Why is Crushing Necessary?
Crushing is the process of reducing mined ore to a suitable particle size for processing. This process is crucial to modern mining:
| Reasons | Explanation |
|——|——|
| Transportation Efficiency | Loose materials can be transported efficiently via conveyors, while large rocks cannot be transported directly.
| Mineral Separation | Crushed minerals are easier to separate from gangue (residue).
| Subsequent Processing | Grinding, flotation, and other processes require feed with specific particle sizes.
| Resource Recovery | Crushed construction waste can be reused as recycled aggregate.
II. Working Principle of Jaw Crusher
2.1 Core Working Principle
The jaw crusher utilizes compression force to crush materials. Mechanical pressure is achieved through two jaw plates—one fixed and one movable.
2.2 Motion Modes
The movable jaw plate performs two types of motion:
- Oscillating Motion: Oscillates towards the fixed jaw plate (driven by the toggle plate)
- Vertical Motion: Up-and-down motion generated by the rotation of the eccentric shaft
The combination of these two motions produces compression and pushing effects, discharging material from the crushing chamber.
2.3 Core Components
| Component | Function | Material |
|——|——|——|
| Fixed Jaw | Static Crushing Surface | High Manganese Steel |
| Moving Jaw | Oscillating Crushing Surface | High Manganese Steel |
| Jaw Liners | Replaceable Wear-Resistant Parts | High Manganese Steel/Alloy Steel |
| Main Shaft | Drives the Moving Jaw | Alloy Structural Steel |
| Flywheel | Stores Inertia, Ensuring Continuous Crushing | Cast Steel |
| Toggle Plate | Transmits Power + Overload Protection | Cast Steel |
| Frame | Supports the Overall Structure | Welded Steel Structure |
III. Classification of Jaw Crusher
3.1 Classification by Jaw Plate Suspension Method
| Type | Suspension Position | Features | Applications |
|——|———-|——|——|
| Blake Crusher | Fixed bottom | Fixed feed inlet, adjustable discharge outlet | Most commonly used, suitable for primary/secondary crushing |
| Dodge Crusher | Fixed top | Uniform product particle size, lower capacity | Laboratory, fine crushing |
| Universal Crusher | Mid-position | Combines features of both | Special applications |
3.2 Classification by Mobility
| Type | Advantages | Applicable Scenarios |
|——|——|———|
| Tracked Mobile Jaw Crusher | Flexible relocation, adaptable to complex terrain, no infrastructure required | Mining, on-site construction waste processing, multi-site operations |
| Fixed/Modular Jaw Crusher | Low cost, high capacity, easy maintenance | Quarries, large mines, long-term fixed operations |
3.3 Classification by Crushing Stage

4.1 Model Comparison Table
| Model | Type | Capacity (TPH) | Maximum Feed | Discharge Adjustment | Drive Method |
|——|——|———–|———|———|———|
| SE-650D | Small Mobile Jaw Crusher | 50-130 | 500mm | Adjustable | Diesel/Electric |
| SE-1060 | Medium Mobile Jaw Crusher | 200-250 | 700mm | Adjustable | Diesel/Electric |
| SE-1160 | Large Mobile Jaw Crusher | 230-280 | 700mm | Adjustable | Diesel/Electric |
| TZ6510 | Dual-Core Jaw Crusher | 80-300 | 650×1000mm | Adjustable | Diesel/Electric |
| SE-J1060 | Modular Jaw Crusher | 200-250 | 700mm | Adjustable | Electric |
| SE-J650D | Small Modular Jaw Crusher | 50-130 | 500mm | Adjustable | Electric |
4.2 Product Dimension Specifications
Jaw crusher model names are usually based on the feed opening size. For example:
- SE-1060: 10 represents a feed inlet width of approximately 1000mm, and 60 represents a length of approximately 600mm.
- 32×54 inches: US standard, indicating a feed inlet width of 32 inches and a length of 54 inches.
4.3 Technical Parameter Details
F80 Rule (Feed Size Calculation)
F80 refers to the maximum size through which 80% of the feed material can pass:
F80 = Inlet width × 0.8
Example: SE-1060 inlet 700mm, F80 = 700mm × 0.8 = 560mm
That is, 80% of the feed width should be less than 560mm.
Crushing Ratio Calculation
Crushing ratio = Maximum feed size / Minimum discharge size
Typical jaw crusher crushing ratio: 6:1 to 8:1
Example: Feed 600mm → Discharge 100mm = 6:1 crushing ratio
