Reliable Spring Cone Crusher PYB1200 Mining Stone Machine for Ore Secondary Crushing

The Reliable Spring Cone Crusher PYB1200 is a proven secondary and tertiary machine for hard and medium-hard ores and rocks. Its robust gyrating cone is driven by a horizontal shaft and bevel gear, and a circumferential spring system acts as a safety device: should unbreakable material enter the chamber, the springs compress and the cone retracts, letting the tramp metal pass without damage. Hydraulic or manual adjustments set the discharge opening precisely, giving close control of product size. With a large reduction ratio, high capacity and low wear cost, the spring cone crusher remains a mainstay in mining and aggregate circuits worldwide.

• Spring Overload Protection: The spring-loaded frame releases the cone when uncrushable material enters, preventing severe damage and costly downtime.
• Large Reduction Ratio: A long crushing stroke and laminated fracture give a high reduction ratio and a well-shaped, evenly graded product.
• Easy Discharge Adjustment: The discharge opening is set by hydraulic or manual means, so product size can be changed quickly to meet market demand.
• Stable Laminated Crushing: A deep chamber and controlled stroke crush material by inter-particle pressure, reducing flakiness and improving product shape.
• Durable Wear Liners: Manganese cone and bowl liners can be rotated and replaced, keeping wear cost low over a long service life.
• Reliable Gear Drive: Ground spiral bevel gearing and heavy bearings transmit power smoothly for quiet, efficient, long-term operation.

Spring cone crushers are used for secondary and tertiary crushing in metal and non-metal mines, cement plants, construction aggregate plants and metallurgical operations. They handle iron ore, copper ore, gold ore, granite, basalt and river gravel, and are frequently paired with a primary jaw crusher and a final screen to complete a closed crushing circuit.

Machines are shipped with the eccentric assembly and bowl protected and the drive components boxed. A spare set of liners and a full tool kit are available. Each crusher is assembled and test-run at the factory. We provide a twelve-month warranty, and our wear-part service helps you plan liner changes ahead of time to avoid production interruptions.
