A sludge drying apparatus is provided to pulverize dried sludge, to recycle metal member and to have high energy efficiency by using mass difference between metal and sludge or magnetic force of magnet and collecting metal member. A mixing unit(30) mixes sludge(10) and metal member(20). An electronic induction heating apparatus(50) generates an inducing current in the metal member mixed with the sludge. A metal member division unit separates the inserted metal member from the sludge dried through the electronic induction heating apparatus. |
