Key Features

• Advanced Moving Jaw Assembly: The PV912 features a durable moving jaw assembly made from high-quality cast steel, contributing to its durability and reliability.
• Integral Cast Steel Bearing Housing: The monolithic cast steel bearing housing ensures a precise fit with the frame, improving radial strength and reducing maintenance expenses.
• Larger Bearings with Higher Load Capacity: Fitted with larger, more durable bearings compared to standard models, the PV912 provides enhanced load capacity and extended bearing lifespan through its efficient labyrinth seal design.
• Symmetrical “V” Shaped Crushing Chamber: Designed with a symmetrical form, significant toggle angle, and optimal stroke, this model enables larger feed sizes, higher throughput, and more consistent particle size while decreasing wear on the jaw plates.
• Hydraulic Wedge Adjustment System: Incorporating a hydraulic wedge adjustment system for the discharge opening, it streamlines the adjustment procedure and boosts automation during maintenance checks. This system also aids in rapid clearance cleaning in case of power failures or blockages.
• Optimized Kinematic Parameters: The PV912 has been designed with larger centrifugal force, steeper toggle angle, and proper speed and flywheel inertia, delivering superior crushing performance.
• Toothed Liners: Outfitted with new toothed liners, the PV912 boosts production and prolongs the service interval of wear parts.
• Rational Structural Design: Employing a modular design for easy disassembly and transport, the raised moving jaw liner effectively shields the moving jaw and bearing chamber, ensuring smooth material flow and preventing jamming, thus achieving optimal continuous crushing performance.
