CS840i Cone crusher

Sandvik CS840i is a high capacity cone crusher for secondary stage crushing. With up to 50% higher capacity, 25% increased reduction ratio and a reduced recirculation by up to 50%, with the same amount of high-value end product compared to similar crushers in its class, it is a true super producer. The wide range when it comes to Closed Side Settings, (CSS), together with more and bigger throws, gives you extreme flexibility as the CS840i can be set to fit a huge variety of capacity needs.

The CS840i brings you a revolution in intelligent crushing. Connected via the My Sandvik portal, it offer 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 also 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 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.
