Jaw crusher, cone crusher and roll crusher are three common types of crushing equipment, and there are some differences in their working principles, structural characteristics and application areas. Each type of crusher has its specific application scenarios and advantages, and choosing the right crusher needs to be decided according to specific material characteristics, production requirements and process flow. Below are the differences between these three types of crushers and their respective advantages and disadvantages:
I. Jaw Crusher
Difference: Jaw crusher crushes materials by periodically pressing the movable jaw plate to the fixed jaw plate, simulating the movement of two jaws of animals.
Advantages:
1. Simple structure, easy to manufacture, reliable work.
2. Crushing large materials, uniform product size.
3. Low operation cost, simple maintenance.
4. Deep crushing cavity and no dead zone, improve feeding capacity and output.
5. Wide range of discharge opening adjustment to meet different user requirements.
Disadvantages:
1. Relatively low productivity and high power consumption.
2. It is easy to be blocked for ores with high moisture and viscosity.
3. Jaw plate wear faster, need to be replaced regularly.
4. Low noise and high dust.
II. cone crusher
Difference: Cone crusher realises material crushing through the relative movement of two cones inside and outside, suitable for medium or fine crushing operation.
Advantages:
1. Crushing large materials with high production efficiency.
2. Low consumption of wearing parts, low operating cost.
3. The hydraulic system ensures the safe operation of the equipment and automatically adjusts the size of the discharge opening.
4. Various crushing cavity design, strong adaptability.
5. Good sealing performance, effectively protect the equipment from dust.
6. Suitable for crushing hard rocks and ores.
7. Low noise, less dust, improve the working environment.
Disadvantages:
1. Relatively complex structure, high maintenance difficulty and cost.
2. Poor crushing effect for high humidity and sticky materials.
3. The weight of the machine is large, increasing the investment and construction costs.
III. Roll Crusher
Difference: Roll crusher crushes the materials in the gap by squeezing or splitting the materials through two round rolls rotating in the opposite direction.
Advantages:
1. It is suitable for coarse crushing and medium crushing, especially suitable for coal, limestone and other materials below medium hardness.
2. Discharge size can be adjusted, the product size is uniform.
3. The roll surface can be designed with teeth to increase the splitting effect.
4. It can crush materials with compressive strength≤160MPa.
Disadvantages:
1. Sticky materials are easy to block the crushing space.
2. Non-crushed materials falling into the double rolls will damage the crusher, resulting in a shutdown accident.
3. When the material to be processed is large, the large pieces of ore are easily squeezed out from the crushing space.
4. The wear and tear of the roll surface is greater after the roller crusher has been running for a longer period of time.
