The main methods for selective extraction of limestone, oil shale and phosphate rock have been selective blasting, bulldozer and excavator ripping and cutting by surface miners. Selective crushing has been achieved by axle crusher and separation by jigging. All methods have shown promising results for changing the waste rock balance in the product.

It is assumed that power is charged to the plant at the rate of 0.75d. per kilowatt-hour in the case of the smallest plant, decreasing as the capacity increases to a minimum of 0.5d. per kw.-hr. for the largest. The power consumption of a machine or installation is usually expressed in kw.-hours per ton as being the most convenient method.

Select the appropriate jaw crusher model: Choosing the right jaw crusher model is essential for achieving the desired reduction ratio. The selection of the crusher model should be based on the material type, feed size, and required product size. Adjust the feed size: The feed size is one of the critical factors that affect the reduction ratio.

Uptime – the percent of time a crusher is working vs. down for maintenance or repair. Productivity – the in spec tons per hour/day/week that the crusher delivers when running. Need more proof? Here's the math. Let's take a mid-sized crushing operation and try to quantify these costs. Assume: • 250 tons per hour production
