A horizontal hammermill shredder is to process 8 tons/hour of MSW to a characteristic size (x0) of 0.7 in. What grate spacing and horsepower would be required to accomplish this?

To determine

Grate spacing and horsepower required by the shredder

Explanation of Solution

Given information:

  Shredder process=8tonshr

  x0=0.7in

Concept used:

From the graph: 4.19, by plotting the characteristic particle size we can find the grate spacing and specific energy. Then the required horsepower of the shredder is calculated.

  hp=E×P

  ESpecific energyPShredder processinghpHorsepower required by shredder

Calculation:

From the figure: 4
