[0002] In the process of processing metallurgical materials by using a drying tower, a blanking device is required to add the metallurgical materials into the drying tower for drying treatment. The existing blanking devices for drying towers, although they can meet the basic requirements for blanking the metallurgical materials, can only perform simple agitation and dispersion treatment on the materials, and cannot remove the moisture on the surface of the metallurgical materials by means of pre-drying treatment of the metallurgical materials, so as to effectively avoid the bonding of metallurgical material particles together. Therefore, there are problems of low dispersion efficiency and poor dispersion effect on the metallurgical materials, which is not conducive to the smooth entry of the metallurgical materials into the drying tower in a non-clumping and non-bonding manner, and will cause the metallurgical materials entering the drying cylinder to easily adhere and bond together or adhere to the inner wall of the drying cylinder, which is not conducive to the user to quickly and efficiently dry the metallurgical materials.
