The utility model relates to a device for drying raw ores in a storage yard by using tail gas waste heat of a ball mill. The device comprises the ball mill (3), a grader (4), a cyclone collector (5), a bag-type dust collector (6), an air compressor (7), an induced draft fan (8), a valve (9) and a perforated air pipe (10). Exhaust gas of the bag-type dust collector is connected with an opening air pipe (10) around the storage yard through a conveying pipeline, an induced draft fan and a valve, and the raw ore (1) of the storage yard (2) is dried through hot air. The device utilizes the tail gas waste heat of the ball mill to dry raw ores in a storage yard, can realize high-valued utilization of the waste heat of the dry-method ball mill, improves the energy utilization rate, simultaneously can reduce the moisture of the raw ores in the storage yard, and avoids the problem of subsequent deep processing caused by high moisture. 一种利用球磨机尾气废热烘干堆场原矿装置，包括球磨机（3）、分级机（4）、旋风收集器（5）、布袋除尘器（6）、空压机（7）、引风机（8）、阀门（9）、开孔风管（10）。布袋
