Types of stone crusher are various, which are widely used in different material treatment scenarios in all sorts of industrial areas. Stone crushers can be categorized into several various types according to different standards. Such as:
- Stationary crusher and mobile crusher, according to the movability
- Jaw crusher and cone crusher, according to the shapes
- Extrusion crusher and impact crusher, according to the working principle.
These crushers with their special advantages are playing crucial roles in varieties of industrial fields, such as mining, building materials production, consturciton waste treatment, road construction and metallurgial smelting, etc.
It is not only a “rock crusher” in the physical sense, but also a “green engine” that promotes recycle and enhances engineering efficiency.
Stone crusher integates multiple functions of feeding, crushing, sieving and conveying. It crushes large rocks, ores, constructin waste and other materials to the special particle sizes through mechanical force, providing raw materials to the subsequent processes such as mineral processing, building materials production and road filling, etc.
Stationary Crusher And Mobile Crusher
Firstly, according to the fixation and movability of the crusher machine and their foundations, crushing machines can be classified into four types: mobile type, semi-mobile type, semi-fixed type and fixed type. These four types of crushers are respectively adapted to different production scenarios. The table gives a clear showing their characteristics as following.
| Product | Mobile Crusher Plant |
| Production | 50-100 T/H |
| Feeding Particle Size | ā¤400mm |
| Types | Characteristics | Advantages | Application Scenarios |
| Mobile Crushing Plant | The track or tire chassis combined by modular design enables autonomous walking. | Flexible relocation, deployment finished within 24 hours, no infrastructure investiment required. | Construction waste treatment, large-scale mining, etc. |
| Semi-mobile Crushing Equipment | The crushing main unit is placed on a suitable working platform, moved as a whole (or in parts) by a crawler transport vehicle or other traction equipment. | The civil construction cost is reduced by 40%, and the production capacity covers 100-800 tons per hour. | Medium-sized mining, sand and gravel aggregate production lines, etc. |
| Semi-fixed Crusher Machine | The crusher is fixed on the concrete foundation and the conveying system is mobile. | Balancing stability and flexibility, the maintenance cost is reduced by 25%. | Coarse crushing of large metal mines, production of aggregates for hydropower station dam bodies, and preparation of chemical raw materials. |
| Fixed Crushing Plant | Permanent concrete foundation, whose position cannot be moved, is generally set up outside the mining site | Stable and mature, with long service life. Initial investment in civil construction is large, construction period is long. High requirements for site selection. | Large-scale open-pit mining |
Crushing Plant Types According To Principles
Secondly, crushing equipment can mainly be sorted into three kinds according to different crushing principles, such as extrusion type, impact type and shearing/grinding type.
Extrusion Crusher Equipment
Jaw Crusher Plant
Principle
The material is extrudued through the reciprocating motion of the movable jaw and the fixed jaw. It is suitable for coarse crushing and medium crushing, with a simple structure and strong adaptability.
Application Scenarios
The core equipment of the coarse process. As the “first process” of the crushing production line, the jaw plant crushes large pieces of materials to less than 100mm, providing the appropriate particle size for subsequent equipment such as cone crushers and impact crushers, and improving overall efficiency.
| Jaw Crusher | PE600Ć900 (mm) |
| Maximum Particle Size | 500mm |
| Adjustable Range of Outlet | 65-160 mm |
| Capacity | 60-160 T/H |
| Motor Power | 75kW |
Cone Crusher Plant
Principle
The materials is squeezed by the relative motion of the inner cone and the outer cone, which is suitable for medium crushing and fine crushing, with high crushing efficiency and low energy consumption.
Application Scenarios
It is used for the secondary and tertiary crushing of metal mines such as iron ore, copper ore and gold ore, further finely crushing the materials after jaw crusher pretreatment to meet the particle size requiements of the mineral procession process.
| Cone Crusher | CS110 |
| Diameter of the Cone (large end) | 1200mm |
| Adjustable Range of Ore Discharge Outlet | 15-50mm |
| Maximum Feeding Size | 180mm |
| Capacity | 100-250 T/H |
| Motor Power | 110kW |
Impact Crushing Equipment
Reaction Stone Crusher
Priciple
The materials are repeatedly impacted and crushed between the rotor and the impact plate, which is suitable for medium crushing and fine crushing, and the product particle shape is nice.
Application Scenarios
This kind of stone crusher machine is widely used in the preparation of high-quality aggregates required for projects such as expressways, railways, and airport runways. It products have a continuous gradation and excellent particle shape, whick can meet the standards of sand and gravel for concrete below C60. They are particularly suitable for the production of 12, 13 gravels (10-20mm) and 05 gravel (5-10mm).
| Product | Impact Crusher |
| Feed Size | ā¤250mm ā¤350mm |
| Discharge Size | 3-60mm |
| Production Capacity | 60-700t/h |
Shearing/Grinding Crushing Equipment
Double-roller Crusher Machine
Principle
The double rollers rotate towards each other to form a shear force field, whihc is particularly suitable for medium and fine crushing of viscous materials (such as coke), with an over-crushing rate of less than 5%.
Application
It is applicable to the preliminary or secondary crushing of medium and low hardness ores such as iron ore and copper ore, providing raw materials of appropriate particle size for the mineral procession process. Its compact structure and simple operation make it particularly suitable for small and medium-sized mining operations.
| Product | Double-roller Crusher Machine |
| Roller Diameter | 400mm-900mm |
| Roller Length | 250mm-1200mm |
| Feeding Size | 32mm-800mm |
| Discharge Size | 2-8mm~75-150mm |
| Production Capacity | 2-5t/h ~ 125-180t/h |
Types Of Stone Crusher According To Stages
| Stages | Feeded Particle Size (mm) | Finished Particle Size (mm) | Crusher Equipment |
| Coarse Crushing | 1500-500 | 350-100 | jaw crusher, gyratory crusher |
