Crushing Efficiency Solution

STEP 0: Pre-Calculation Summary
Formula Used
Crushing Efficiency = (Surface Energy Per Unit Area*(Area of Product-Area of Feed))/Energy Absorbed By Material
ηc = (es*(Ab-Aa))/Wh
This formula uses 4 Variables
Variables Used
Surface Energy Per Unit Area - Surface energy per unit area is the excess energy at the surface of a material compared to its volume. (Measured in Newton per Meter)
Area of Product - Area Of Product is the area per unit mass of the milled material. (Measured in Meter^2/Kilogram)
Area of Feed - Area of Feed is the area per unit mass of the feed. (Measured in Meter^2/Kilogram)
Energy Absorbed By Material - Energy Absorbed By Material is the energy that the material particles acquires while the material is being crushed . (Measured in Joule per Kilogram)
STEP 1: Convert Input(s) to Base Unit
Surface Energy Per Unit Area: 1 Newton per Meter --> 1 Newton per Meter No Conversion Required
Area of Product: 8 Meter^2/Kilogram --> 8 Meter^2/Kilogram No Conversion Required
Area of Feed: 7 Meter^2/Kilogram --> 7 Meter^2/Kilogram No Conversion Required
Energy Absorbed By Material: 20 Joule per Kilogram --> 20 Joule per Kilogram No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
ηc = (es*(Ab-Aa))/Wh --> (1*(8-7))/20
Evaluating ... ...
ηc = 0.05
STEP 3: Convert Result to Output's Unit
0.05 --> No Conversion Required
FINAL ANSWER
0.05 <-- Crushing Efficiency
(Calculation completed in 00.000 seconds)

Crushing Efficiency
Crushing Efficiency = (Surface Energy Per Unit Area*(Area of Product-Area of Feed))/Energy Absorbed By Material Go
Energy Absorbed by Material While Crushing
Energy Absorbed By Material = Surface Energy Per Unit Area*(Area of Product-Area of Feed)/Crushing Efficiency Go
Reduction Ratio
Reduction Ratio = Feed Diameter/Product Diameter Go

Crushing Efficiency Formula

Crushing Efficiency = (Surface Energy Per Unit Area*(Area of Product-Area of Feed))/Energy Absorbed By Material
ηc = (es*(Ab-Aa))/Wh

What is Size Reduction in mechanical operations?

Size reduction refers to an operation wherein particles of solids are cut or broken into smaller pieces. Size reduction is a mechanical process of breakdown of solids into smaller size particles without altering the state of aggregation of solids. It is also called comminution.

How to Calculate Crushing Efficiency?

Crushing Efficiency calculator uses Crushing Efficiency = (Surface Energy Per Unit Area*(Area of Product-Area of Feed))/Energy Absorbed By Material to calculate the Crushing Efficiency, Crushing Efficiency is defined as the ratio of surface energy created by crushing to the energy absorbed by the solid. Crushing Efficiency is denoted by ηc symbol.
