PROBLEM TO BE SOLVED: To provide a facility and method for recovering metal in slag, capable of high accurately separating/recovering metal in slag (i.e., iron particles in ironmaking slag) in a short time.SOLUTION: A facility 10 for recovering metal in slag includes a slag charging chute 1 for charging slag 8 (metal particles 8b and slag 8a having a silica compound as a main constituent are fixed with each other), a rotary crushing device (a pin setting base 2 and a crushing pin 3) for crushing the slag 8 by making a rotor collide with the charged slag 8, a fixed sieve 5 for performing separation into a material smaller in size than the sieve mesh and a material larger in size than the sieve mesh with the rotary crushing device, a metal particle recovering device (a shutter 6, a recovery duct 7) for recovering the material scattered in the rotary direction of the crushing pin 3 as metal particles 8b, a crushing chamber 4, and a base part 9.
