A horizontal type ball mill operation medium bolt coordination auxiliary device comprises a machine body (1) which is provided with a pressure sensing module (2), a fastening test module (3), a remotecommunication module (4) and a management module (5). During operation, the pressure sensing module (2) is arranged on a grinding medium; the fastening test module (3) is arranged on a bolt; the remote communication module (4) transmits sensed information to the management module (5) to be processed; the pressure sensing module (2) is provided with a material feeding module (6), and when it is sensed that the medium pressure is not enough, materials are fed in time; the fastening test module (3) is provided with an amplitude adjusting module (7); and a prompt module (8) is arranged on the management module (5). By feeding the materials in time and ensuring the tightness of the bolt, operation is smooth, and the service life of the components is prolonged.
