Applications

Primary use: Fixed (bowl liners) and moving (cone liners) components in hydrocone crushers for secondary crushing
Industries / Locations:
- Mining: limestone and granite operations in Kenya
- Cement production: Nairobi & Mombasa
- Construction: concrete and asphalt aggregate production
Types:
- Concave (Fixed / Bowl Liner)
- Mantle (Movable / Cone Liner)

Extended wear life: 18–28% longer lifespan (700–1800 tons) compared to standard liners due to 0.5% Mo content
Consistent output: Controlled CSS producing 4–48 mm uniform aggregates
Market compatibility: Fits modern, Delta, and Sandvik hydrocone models commonly used in Kenya
Cost-effective: Approximately 200 million IRR vs. OEM 400+ million IRR
Easy installation: Press-fit design allows setup in ~1 hour
High-temperature resistance: Suitable for warm and humid climates up to 145°C

Installation: Mount on shell/shaft; adjust CSS; ensure leveling ±0.05 mm (~1 hour)
Maintenance: Lubricate every 200 hours; replace if wear >5 mm; monitor temperature (<145°C)
Transport & Handling: Maximum 675 kg per trailer set; 10-ton crane recommended
