The crushed stone output from a 47- by 34-in. crusher, with a closed opening of 3 in., is passed over a single horizontal vibrating screen with 2-in. openings. If the permissible screen efficiency is 85%, use the information in the book to determine the minimum-size screen, expressed in square feet, required to handle the output of the crusher.
