CH870i Cone crusher
Sandvik CH870i is a technologically advanced, high-capacity cone crusher designed for crushing applications in mines or large sized quarries. Each crusher has a hydraulically supported main shaft which is supported at both ends. With a robust design, adjustable eccentric throw, a constant intake opening, high performance can be achieved by proper selection of a Sandvik OEM crushing chamber.
It brings you a revolution in intelligent crushing. Connected via the My Sandvik portal, it offers 24/7 access to data generated by your connected Sandvik crusher fleet. Now you can make decisions based on facts, and clearly see areas where you can improve uptime and productivity. My Sandvik gives you access to manuals and an e-commerce platform for easily and efficiently buying and reordering wear and spare parts. It lets you track and trace parts online to make maintenance planning simpler.
The main shaft is now 65% stronger and both the top and bottom shells have been strengthened and cast-optimized by up to 50% for maximum reliability and higher availability. Bolted rather than welded arm and body liners reduce maintenance time by up to 90% making the process faster and safer. The improved over-pressure system with dedicated air channel inlets helps protect your crusher from dust to improve reliability.
When used in secondary crushing applications, the Sandvik CH870i delivers high capacity thanks to its 600 kW motor delivering higher power and more crushing force at maximum throw. The Sandvik CH870i is also suitable for high reduction tertiary/pebble applications. The increased crushing force facilitates higher size reduction, resulting in a finer product size and less circulating load in closed circuits.
The automation system optimizes the performance of the crusher without overloading it, allowing you to get the most out of your crusher. It can also automatically adjust your crusher settings to compensate for crushing chamber wear – ensuring consistent product size.
- Hydroset™ system provides safety and setting-adjustment functions
- ASRi™ automatically adapts crusher to feed conditions
- Unibody mainframe ensures optimal strength and less maintenance
- Lifting from above minimizes risks and allows for safer maintenance
- The electric dump valve system protects your crusher against unwanted pressure peaks greatly improving its performance and reliability
