METHOD AND APPARATUS FOR MANUFACTURING CRUSHED SAND

摘要

PROBLEM TO BE SOLVED: To solve a problem that conventional methods and apparatus for manufacturing crushed sand cannot manufacture the crushed sand by controlling the fine particle quantity as desired.SOLUTION: A apparatus for manufacturing crushed sand 1 manufactures continuously crushed sand C with any fine particle quantity by supplying a predetermined fine particle quantity of crushed sand A and a larger fine particle quantity of crushed sand B than the predetermined fine particle quantity of the crushed sand A at a first feeding amount control part 22 and a second feeding amount control part 24 so that a mass ratio becomes a predetermined ratio set by controlling by a control part 26, and mixing continuously in a mixing part 25.
