Fixed Jaw C 400.2207, Swing Jaw C 400.1101 and Cheek Plate Suit 400.00639 are a matched set of critical wear and protective parts for Sandvik CJ211/QJ331 Crusher. They weigh 1082kg, 1105kg and 223kg respectively. The set includes 3 fixed jaws, 3 swing jaws and 4 cheek plate suits. These components work synergistically to drive the entire crushing process. They are widely applied in mining, quarrying, aggregate processing and construction waste recycling industries. They perform stably under high-load, high-vibration working conditions. Their quality directly affects the crusher’s production capacity, particle size uniformity and overall operational efficiency. They are indispensable for enterprises pursuing low-cost and high-productivity operations.
All three parts are crafted from premium MN22CR2 high-manganese steel. The material undergoes a specialized quenching and tempering heat treatment process. This process boosts surface hardness to HRC 60-62 while maintaining internal toughness. The fixed jaw forms a solid, immovable base for the crushing chamber. It prevents material slipping during operation. The swing jaw delivers powerful, reciprocating impact force. It squeezes materials against the fixed jaw for efficient fragmentation. The cheek plate suit protects the crusher’s main frame from flying debris and abrasive wear. It extends the service life of the equipment’s structural components. Together, this set improves crushing efficiency by 20% compared to ordinary parts.
The jaw plates and cheek plate suit are manufactured with advanced 5-axis CNC machining technology. They comply with strict OEM standards for Sandvik CJ211/QJ331 Crusher. Every production step is monitored by professional quality control teams. Dimensional tolerance is controlled within ±0.3mm. This ensures perfect compatibility with the original equipment. No on-site welding, cutting or drilling is required during installation. The products come with pre-drilled mounting holes and precise alignment marks. This feature saves significant maintenance time and labor costs. It also minimizes equipment downtime for replacement. The products are packed in high-strength wooden cases with shock-absorbing padding to prevent damage during transportation.
