What Crusher Should You Choose for Primary Crushing?
What is a primary crusher?
Types of primary crushers
The most common types of primary crushers:
-
Gyratory crusher
- Jaw crusher
- Hammer crusher
1. Gyratory crusher
They are good at handling dry to slightly wet materials, but not very suitable for sticky materials.
allows continuous operation and supports full feed without pre-screening or removing fines.
-
High capacity: A processing capacity of 2000–10000 TPH.
- Low energy consumption: Large and medium-sized gyratory crushers consume less energy than the same types of jaw crushers.
- Low maintenance: Even wear distribution reduces liner replacements and maintenance costs.
- Environmental performance: Fully enclosed design with excellent sealing ensures superior environmental protection.
have a higher initial investment cost due to their complex structure and large size of the outer shell.
2. Jaw crusher
These compression crushers perform better with high moisture and high viscosity materials like clay, with a reduction ratio of 6:1. They operate intermittently and require even feeding from Crusher.
-
Mining: Primary crushing of iron ore, copper ore, gold ore, and other metal ores.
- Construction: Preprocessing of limestone, Crusher, and other construction materials.
- Chemical and building materials: Initial crushing of gypsum, coal, ceramic raw materials, etc.
-
Simple operation: Jaw crushers are easy to operate, even for beginners.
- Lower cost: Compared to gyratory crushers, they require less investment, saving money.
- Easy maintenance: Liners are easy to replace, with minimal downtime and a small footprint.
3. Hammer crusher
Crusher are widely used as primary crushers in the aggregate and industrial markets, suitable for materials such as Crusher, limestone, concrete aggregates, bauxite, construction waste, cement clinker, slag, and coke.
-
Wide application: Suitable for both dry and wet crushing, for materials with up to 15% moisture.
- One-time forming: Eliminates the need for primary and secondary crushing, reducing costs by approximately 40%.
- Large feed opening: Handles feed sizes up to 1000 mm, making it ideal for coarse crushing.
- Non-clogging: Designed to ensure smooth flow of high moisture and clay materials, preventing buildup.
