It brings you a revolution in intelligent crushing. SAM by Sandvik gives you complete 24/7 access to data generated by your connected Sandvik crusher fleet. Make decisions based on facts, and clearly see areas where you can improve uptime and productivity. Get access to manuals and an e-commerce platform to easily and efficiently buy and reorder wear and spare parts. SAM by Sandvik lets you track & trace parts online to make maintenance planning simpler. No other crushers are better connected.

The CS840i comes with the new generation Automation and Connectivity System (ACS) as standard. The system continuously monitors and optimizes crusher performance and controls the complete lubrication system, increasing uptime and reliability. It can automatically adjust crusher settings to compensate for crushing chamber wear– ensuring consistent product size.

Bolted rather than welded top and bottom shell liners reduce maintenance time and are much safer. It’s 90% faster to change liners compared to welding. The improved over-pressure system with dedicated air channel inlets keeps dust out to increase reliability. The standard off-line filter unit keeps the lubrication oil cleaner with 24/7 fine filtration, reducing wear on your internal crusher components and extending oil life by up to 5 times.


  • Automation & Connectivity System (ACS) Automatically adapts the crusher to varying feed conditions ensuring maximum 24/7 performance
  • Hydroset™ system provides safety and setting-adjustment automatically adapts crusher to feed conditions
  • Unibody mainframe ensures optimal strength and less maintenance
  • Lifting from above minimizes risks and allows for safer maintenance
