Industrial Grinding & Crushing Series

Potassium Feldspar Specialized Hydraulic Double Roller Crusher

Heavy-Duty 2PGY Series | High-Purity Iron-Free Crushing | Optimized Ball Mill Pre-treatment

The 2PGY Series High-Pressure Hydraulic Double Roller Crusher is specifically engineered to handle highly abrasive and brittle silicate minerals like Potassium Feldspar (K-Feldspar). By utilizing dual counter-rotating high-alloy rollers paired with responsive hydraulic positioning systems, it delivers massive static compression force to break down minerals right along their natural crystal cleavage boundaries—instantly upgrading your finished product grade.

Key Product Advantages

1. Strict Whiteness Protection (Zero Iron Contamination)

Traditional high-speed impact mills chip away iron particles into the feldspar, causing ugly dark defects after furnace firing. Our low-RPM rollers gently compress materials with minimum friction. Combined with manganese-free high-alloy roller surfaces, it protects the pure white color required for high-grade ceramic glazes and precision glass manufacturing.

2. Anti-Overcrushing Mechanics (Fewer Fines, Higher Yield)

Feldspar structures fracture easily. Our single-pass hydraulic extrusion breaks the material precisely at your desired gap setting without recycling it through internal impacts. This method saves valuable ore by reducing useless ultra-fine dust and waste sludge by 15% to 25%.

3. Boosts Downstream Ball Mill Capacity by 30%-40%

By pre-crushing raw feldspar into fine, uniform 2mm-8mm cubic particles with high micro-cracks, it relieves the stress on your subsequent ball mills. This simple step saves plant power and expands your fine powder production capacity considerably.

4. Instant Tramp Iron & Quartz Automatic Reset

When encountering uncrushable impurities like hard quartz veins or metal teeth, the intelligent hydraulic accumulators pull back the movable roller instantly to let the object pass safely, resetting back to the normal workspace in seconds without stopping production.
