Core features of cone crusher
1. Efficient crushing: Conical rotor and multi-layer wear-resistant lining design are used to achieve fine crushing of materials through impact, extrusion and other methods; suitable for crushing various hard rocks such as granite, basalt, limestone, iron ore, etc.
2. Structural optimization: Split hydraulic adjustment device can quickly adjust the shape of the crushing chamber and the particle size of the discharge; high rigidity frame and self-lubricating bearing technology reduce maintenance costs.
3. Energy efficiency and environmental protection: Low energy consumption when running at full load, dust control is better than traditional equipment; some models are equipped with intelligent monitoring systems (such as vibration sensors) to warn of faults in real time.
4. Typical application scenarios
Mining: Secondary crushing (further processing after coarse crushing).
Sand and gravel aggregate: Final crushing of sand and gravel aggregate for construction.
Metallurgical industry: Crushing industrial waste such as coke and slag.
Highway construction: Preparation of asphalt mixture aggregate.

Application scenarios of cone crusher
1. Mining (core application area)
Coarse and medium crushing
Used for secondary crushing of metal ores such as iron ore, copper ore, gold ore, etc. (medium crushing after coarse crushing), crushing large pieces of raw ore to a moderate particle size for subsequent grinding or screening.
Tailing treatment
Treat large particles of impurities in mine tailings to improve resource recovery rate.
2. Sand and gravel aggregate production line
Final crushing link
Crush granite, basalt, limestone and other rocks into sand and gravel aggregate for construction (such as 5-25mm fine aggregate) to meet the needs of concrete, asphalt pavement, etc.
High hardness material crushing
Applicable to rocks with high quartz content to avoid the "stone hitting stone" wear problem that is prone to occur in impact crushers.
Key factors for selecting cone crushers
1. Material characteristics: hardness (Mohs hardness>5 requires heavy-duty models), humidity (high moisture content requires anti-blocking design).
2. Crushing requirements: coarse crushing (large feed opening, low speed), medium crushing (medium feed, medium speed), fine crushing (small feed, high speed).
3. Site restrictions: When the space is narrow, vertical cone crusher can be selected, which occupies a small area; mobile crushing stations are preferred for open-air operations.
Typical application cases
An iron mine in Africa: PYC-1200 cone crusher is used for secondary crushing of iron ore, with a daily processing capacity of 3,000 tons.
China Southern Sand and Gravel Plant: PEW-1600 hydraulic cone crusher with vibrating screen produces 5-15mm grade sand and gravel aggregates.
European Construction Waste Treatment Center: Mobile cone crusher + jaw crusher combination, crushing waste concrete and screening out recycled aggregates.
Purchase suggestions for cone crushers
Clear requirements: Select models based on material hardness, output requirements and site conditions.
Brand comparison: Pay attention to the wear resistance of the equipment (such as high chromium cast iron lining) and after-sales service network.
Energy consumption verification: Require manufacturers to provide energy efficiency test data under actual working conditions.
