1.crusher area theory von rittinger p r proposed the area theory in 1867. it is believed that the work done when an external force breaks an object will be converted into surface energy on the new surface area. therefore, the energy consumption for crushing is proportional to the new surface area during crushing.

It is not true that a one-half ball charge consumes proportionately more power than a one-third ball charge. The difference in weight between the tow charges is about 50% but the center of gravity of the larger is nearer the center of rotation of the Mill. Consequently, the power required to turn the larger charge only runs between 15 and 20% more.

A crusher is a machine designed to reduce large rocks into smaller rocks, gravel, sand or rock dust.. Crushers may be used to reduce the size, or change the form, of waste materials so they can be more easily disposed of or recycled, or to reduce the size of a solid mix of raw materials (as in rock ore), so that pieces of different composition can be differentiated.

In 3 hours, that is 1.5 kWh. To get the dollar amount, we need to multiply electric consumption by the cost of electricity. If we presume $0.1319 per kWh electricity cost, one wash will cost us: Electricity Cost = 1.5 kWh * $0.1319/kWh = $0.20. Example 2: Air Conditioner Power Consumption Per Month (3,000W AC Unit) Summers can be hot.
