Feldspar Hydraulic Double Roller Crusher: Heavy-Duty 2PGY Series

Iron-Free Purity Protection | Sharp Over-Crushing Control | For Ceramic & Glass Grade Minerals

1. Absolute Zero Iron Contamination (Secures Premium Whiteness)

In the ceramics and optical glass industries, even 0.1% of tramp iron dust will stain the fired matrix yellow or black. Because our system relies on low-speed (60-80 RPM) hydraulic squeezing instead of high-speed hammer fracturing, abrasive wear-shedding is eliminated. This ensures an iron-free processing chain that keeps feldspar iron oxide levels at their absolute minimum.

2. Sharp Over-Crushing Control (Minimizes Tailing Slimes)

Brittle silicate rocks like feldspar turn into useless powder slime under 0.5mm when hit by traditional VSI or hammer mills, leading to over 20% material loss at the washing stage. The 2PGY series passes material once through an automated, locked laminar gap. Particles break cleanly along natural crystal boundaries, keeping fine powder waste below 8%.

3. Micro-Fracture Genesis (Slashes Ball Mill Power Bills by 25%)

Our high-pressure squeezing does not just reduce particle size; it infuses the cubic feldspar grains with invisible internal micro-cracks. When these pre-stressed particles enter downstream silica-lined ball mills, they grind in significantly less time—expanding milling output capacity by 30% to 40% and dropping total plant power costs.

4. Intelligent Gas-Hydraulic Tramp Material Bypass

Feldspar veins frequently conceal highly abrasive vein quartz blocks or uncrushable metal excavator teeth. Our smart PLC hydraulic accumulator system instantly backs away the movable roller to discharge the uncrushable piece safely, resetting to its precise preset gap within seconds without halting the active production line.
