The invention discloses an accelerating separation device, a leveling device and a roller kiln. The accelerating separation device comprises a plurality of roller bars which are sequentially arranged at intervals to form a conveying line, the conveying line is provided with a low-speed section and a high-speed section which are sequentially connected in the conveying direction, and the low-speed section and the high-speed section are each provided with the more than two roller bars; at least one roller bar, closest to the high-speed section, in the high-speed section is a composite roller, each composite roller comprises more than one annular rotating piece used for supporting materials and a mandrel driven by a second driving device to rotate, and the annular rotating pieces are installed on the mandrels in a sleeving mode in the mode that the annular rotating pieces can rotate on the mandrels and generate resistance during rotation to hinder rotation of the annular rotating pieces. The leveling device comprises the accelerating separation device and a material blocking and leveling mechanism. The roller kiln comprises a furnace body with a hearth and a roller bar type conveying line, and the roller bar type conveying line is provided with the accelerating separation device or the leveling device. The accelerating separation device, the leveling device and the roller kiln have the advantages of being simple in structure, low in cost, easy to manufacture and implement, capable of reducing the possibility of material disorder and jamming and the like.
