The effectiveness of a machine or system is called efficiency. The efficiency is dimensionless. This means there is no unity. It only states what the relationship between effort and benefit or incoming and outgoing energy is. The efficiency can have values between 0 and 1. To calculate, enter the input value P1 and the output value P2.

The reduction ratio is a critical factor in determining the efficiency of a jaw crusher, as it directly affects the size and capacity of the machine. In this article, we'll …

The capacity and efficiency of are usually inversely proportional. The usual target is a efficiency of 95%. An efficiency of 99% will equate to a significant loss of capacity. Efficiency is the ratio of undersize material in the feed that actually passes from the media to the undersize material that should pass from the media.

Jaw Crusher Reduction Ratio. Either an 8-to-1 or 6-to-1 ratio should be the target reduction ratio for maximum jaw crusher efficiency. This setting typically provides an ideal P80 factor—when 80% of crushed material produced by primary crushing will pass screening after processing.

When we apply the Bond Equation we found that CWi (Calculated) = 21,54 Kwh/t. And the CWi (lab test) = 27,4 Kwh/t. My question is: there is same correction factor that we must apply on Bond equation? For your information if you need it: RWi = 19,3 Kwh/t; BWi = 17 Kwh/t; F80 Rod = 10mm; Transfer size= 886µm; P80 final size = 75 µm; Thank you ...

The following set of equations represents the way to calculate the efficiency of the actual jaw crusher using the Rose and English model and selecting a specific …

Similarly, the way it uses fuel to transport determines its efficiency. Efficiency Formula. We can calculate the efficiency of anything by dividing the energy input and the energy output by . We use this equation generally to represent the energy in the form of heat or power. Therefore, the formula comes as:

Where C represents the impact crushing strength (1) in foot-pounds per inch of thickness and S is the specific gravity, the Work Index is found by Equation 3. Equation 3: Wi = 2.59 C/S. How to Find Impact Crushing …

Current Efficiency Formula: Current efficiency is a measure of how effectively an electrical system or process converts the input current into useful output. It is typically expressed as a percentage and is crucial for assessing the performance and efficiency of electrical devices, electrochemical processes, and energy storage systems.

Jul 26, 2015· E = screen efficiency, % r = % oversize in crusher product. To help understand this determination and the equation use, take the example of 200 tph original or new material to the crusher. Assume screen efficiency and 30% oversize in the crusher input. For the successive cycles of the circulating load:

The efficiency formula is applied to calculate the efficiency of any given input. It has no unit and expressed in percentage. Solved Examples. Example 1. If a cyclist puts 600 J of work on his bicycle and the bicycle gives out 140 J of useful work. Calculate the efficiency of a cyclist. Solution: Given: Work Input = 600 J, Work Output = 140 J

Sizing a crusher can be done reliably calculated thanks to the Impact/Crushing Work Index and the testwork research done by Fred Chester Bond and his 1952 paper. According to Bond's Third Theory of Comminution, the work/energy input is proportional to the new crack tip length created during particle breakage and equivalent …

You must use the efficiency formula, output divided by input, to calculate efficiency. It will give you a ratio to convert to a percentage by multiplying by 100. For example, if a machine produces 100 units per hour and requires 200 watts of power, the efficiency can be calculated as 100/200 = 0.5 or 50%. It means the machine converts …

The volume formula then becomes. W = 3.13 D³. In order to bring the formula for work as advanced by Gates into as close agreement with this formula as possible it is assumed that in the case cited by Eads rupture would have taken place with a very slightly greater deformation than he gives, say 0.0004 in. per inch. The formula …

To calculate the efficiency of a jaw crusher, you will need to consider a variety of factors, such as the size of the feed material, the size of the crushed material, and the speed of the jaw crusher.
