FIGURE 4: BOND CRUSHING WORK INDEX v. UNCONFINED COMPRESSIVE STRENGTH (highlighting three rock types) Figure 4 displays Wi C and UCS values separated by the major rock types from a single African mine. The three rock types do show a mild correlation between crushing Work Index and UCS (R² values between 0.1 and 0.4).

Typical hard-rock crushers like jaw, gyratory and cones break rock by nipping the ore between a fixed/stationary and a moveable wear-resistant surface/liner. ... The Bond' Crushing Work Index is common to calculate the power needed to crush rocks from a given F80 size to a resulted P80 product size.
The idea is that. Only dupe a and b are allowed inside the rock crusher room but not inside the igneous rock storage so they can't supply though they are able to supply other buildings. Dupes c to z are allowed inside the igneous rock storage but not inside rock crusher room so they can fill the storage but not supply.

Rock Crusher is a station that destroys stone-like blocks (like Cobblestone, Limestone, Meteorite Rock, etc.) and returns any useful materials that were hiding inside these rocks.Most blocks cost 0 pixels, and the materials within them can be very valuable, so this is very beneficial to do. Rock Crusher processes 1 block every 0.25 seconds.

The kilowatt-hours per tone (kWh/t) will work out your work index. The number of kittowatts consumed in a hour divided by the tonnes of rock gives you your work index. Remember, the higher the Work Index the more work required to crush the rock. This will impact the equipment chosen for your project.
