Rugged Impact Crusher PF-1210 Aggregate Stone Crushing Machine for Mining

The Rugged Impact Crusher PF-1210 applies high-speed impact energy to reduce medium-hard and soft rocks into well-shaped cubical aggregate. A heavy-duty rotor fitted with chrome-molybdenum blow bars strikes the feed against adjustable impact plates, producing a high reduction ratio in a single pass. This makes the PF series an economical choice for secondary and tertiary crushing where product shape and gradation matter. Its large feed opening accepts substantial lumps, while the hydraulic opening device gives quick access to the rotor and liners for maintenance.

• High Reduction Ratio: A large rotor diameter and optimized blow bar geometry reduce material in a single stage, cutting the number of crushing steps in many aggregate circuits.
• Excellent Product Shape: Impact action along natural fracture lines yields cubical particles with low flakiness, improving the quality of concrete and asphalt aggregate.
• Chrome Molybdenum Blow Bars: Rotor blow bars are cast from wear-resistant chrome-molybdenum alloy, providing long service life and consistent impact performance on abrasive rock.
• Adjustable Impact Plates: The gap between blow bars and impact plates is easily adjusted to control top size without dismantling the machine, giving fine control of gradation.
• Hydraulic Frame Opening: A hydraulic opening mechanism exposes the rotor and impact plates so worn parts can be replaced quickly, reducing maintenance downtime.
• Heavy-Duty Rotor: The stress-relieved rotor is dynamically balanced and mounted on heavy spherical roller bearings for smooth operation at high speed.

The PF impact crusher excels in secondary crushing of limestone, dolomite, shale, gypsum, coal gangue and medium-hard ores. It is a core machine in aggregate production lines, concrete batching plants, dry mortar lines and mineral processing flowsheets. Contractors also deploy it for construction and demolition waste recycling, where its tolerance of rebar-contaminated feed and its ability to produce specification aggregate are decisive advantages.

Machines are delivered in reinforced export cases or steel frames with the rotor locked and fragile components cushioned. Blow bars and impact plates are packed separately and labeled. Each shipment includes wear-part drawings, an operation manual and a spare set of fasteners. Every crusher is trial-run under load before shipping, and we provide a twelve-month warranty together with prompt global spare-part service to keep your line productive.
