PROBLEM TO BE SOLVED: To provide an apparatus for removing large lumps with a diameter of D mm or above from granulated dust mostly small in particle size and extremely partially containing large lumps with a diameter of D (wherein D is an arbitrary numerical value of 30-100) mm or above, specifically, from granulated dust 99 or above mass% of which has a particle size of below D mm and which contains below 1% of large lumps with a particle size of D mm or above without using an expensive vibration sieve or classifier. SOLUTION: This net basket 2 for removing the large lumps from the granulated dust is constituted so that the under surface 2b thereof is formed of a net 3 having meshes with a diameter of D (wherein D is an arbitrary numerical value of 30-100) mm matched with the size of the large lumps wanted to be removed and the side surface 2a thereof is formed of the net 3 with a mesh size of D mm or below or a mesh free plate, a part or the whole of the meshes of the under surface formed of the net having the meshes with the diameter D (wherein D is the arbitrary numerical value of 30-100) is inclined and a large lamp removing door 2d is formed to at least one place of the under surface 2b or side surface 2a.
