Each batch of purchased raw and auxiliary materials is inspected according to the raw and auxiliary materials acceptance standards. Optical detection is used for color sorting of raw and auxiliary materials that do not meet the quality standards. After the screening is completed, a metal detector is used for detection to control the content of each component: Fe≤1.2mm, SUS≤2.5mm, Non-Fe≤2.0mm. The raw and auxiliary materials that meet the standards are sent to the industrial microwave energy equipment; In the above step 2, the industrial microwave energy equipment is used to mature the equipment after testing, the power of the industrial microwave energy equipment is controlled to 66Kw, the temperature of the heating zone is set to 100°C, the temperature of the high temperature zone is set to 120°C, and the temperature range of the material during the ninth contact is 130-190°C; the material treated by the industrial microwave energy equipment is transported to the hot air circulation oven for heating, the temperature is controlled to be 0-150°C, the heating pipe (53) heats the air to increase the temperature inside the hot air circulation oven, the output end of the seventh motor (42) drives the left blower (43) to blow air, and the heat is transported to every corner, and the hot air passes through the material and returns to the left blower (43) from the left air inlet duct (44). , completing a closed loop, using the ninth motor (58) to drive the right blower (56) and the eighth motor (48) to drive the top blower (47) in turn, heating the material evenly through hot air in different directions, ensuring that the moisture content after curing is ≤5.0%, and realizing that the hot air circulation of the hot air circulation oven can be carried out from multiple directions, and for special items, the temperature can be guaranteed to be uniform; after the heating is completed, the output end of the sixth motor (41) drives the third transmission shaft (52) to rotate, driving the cylindrical gear (51) to rotate, and then driving the movable plate (37) with the tooth groove to move outward, and finally the heated material is automatically moved out of the hot air circulation oven for natural cooling without human contact, thereby eliminating safety hazards; In the above step 3, the cooled material is put into the grinding machine for simple pulverization, and the simply pulverized material is put into the ball mill for ultrafine pulverization.
