Disclosed is an induction device for an automatic feeding pulverizer. The induction device comprises a machine body (1) provided with a contact induction module (2), a monitoring module (3), an information receiving module (4) and a management module (5). During operation, the contact induction module (2) induces material conditions of a contact area of the contact induction module (2). The monitoring module (3) monitors whether impurity blending occurs to materials entering the monitoring module (3). Induced and monitored information is transmitted to the information receiving module (4) and processed by the management module (5) finally. The machine body (1) is provided with a setting module (6) setting the quantity of materials capable of entering the automatic feeding pulverizer once. The management module (5) is provided with a warning module (7) sending prompt information when material abnormity is induced. Damage to the automatic feeding pulverizer due to mixing-in of iron block hard objects during feeding of the automatic feeding pulverizer is prevented, so that the service life of the automatic feeding pulverizer is prolonged more effectively.
