200 T/H River Pebble Manufactured Sand Production Line

Heavy-Duty 2PGY1500×1200 Crushing Circuit | High-Hardness Aggregate Processing

1. The Customer’s Challenge

The client operates a major commercial aggregate plant supplying high-specification concrete sand for regional highway and bridge structures. Their primary raw material is local river pebble (cobblestone)—a highly abrasive material with an exceptionally high quartz content and a Mohs hardness rating of 7-8.

Previously, the plant utilized vertical shaft impact (VSI) crushers for secondary and fine crushing. Due to the severe abrasiveness of the pebbles, the VSI rotor tips and wear parts degraded every 3 to 5 days, resulting in skyrocketing maintenance costs and frequent production downtime. Furthermore, the massive power grid draw and excessive fine dust generated did not comply with local green industrial regulations.

2. Engineered Technology Blueprint

To address severe component wear and stabilize the production curve, APEX engineers deployed the 2PGY1500×1200 Large Hydraulic Double Roller Crusher. Operating on a static pressure extrusion framework, this design completely eliminates high-velocity impact friction:
