The invention relates to an efficient bone powder preparing system which comprises a bearing base, bearing vertical columns, a high-pressure prefabricated bin, a low-temperature crushing bin and a conveying pipe. The bearing vertical columns are vertically connected with the upper surface of the bearing base, and the high-pressure prefabricated bin and the low-temperature crushing bin are slidablyconnected with the side surfaces of the bearing vertical columns through driving sliding rails. The high-pressure prefabricated bin mutually communicates with the low-temperature crushing bin throughthe conveying pipe. The high-pressure prefabricated bin comprises a tank body, a stirring device, an ultrasonic vibration mechanism, an irradiation heating device and high-temperature and high-pressure water vapor connecting end openings. The low-temperature crushing bin comprises a smashing cabin, crushing rollers, a bone powder grinding mechanism, an ultrasonic crushing mechanism, an ultrasonicvibration mechanism and a refrigerating unit. A using method of the efficient bone powder preparing system comprises three steps of bone material pretreatment, material conveying and low-temperaturepowder preparing. The production efficiency and quality of bone powder products can be effectively improved, and standardization of the bone powder preparing process can further be effectively improved.
