In round numbers, the VSI would cost $130,000, while the cone would come in at $350,000. With these numbers, it is not quite the 3:1 rule of thumb, but it comes close. For the gravel application, consider a 200-hp cone crusher at a price of $300,000 versus a smaller VSI at a price of $90,000. Again, it is close to that 3:1 ratio.
