The daily maintenance of stone mill flour mill includes the detection of dust, temperature, noise and humidity. Pay close attention to daily changes and strictly control to reduce the error to a small extent. The specific maintenance and operation points of stone flour mill are as follows:

日常維護及校驗維修中對影響檢驗結果的因素，如粉塵、溫度、濕度、振動、噪音、腐蝕等因素要密切注意，嚴加控制，減小誤差。要保證所有儀器工作臺面固定、平整，符合使用要求。

During routine maintenance and calibration maintenance, pay close attention to the factors affecting the inspection results, such as dust, temperature, humidity, vibration, noise, corrosion and other factors, and strictly control them to reduce the error. Ensure that all instrument worktops are fixed, flat and meet the use requirements.

所有面粉機儀器使用后應及時清理和還原，以保證下次實驗的順利進行。用電設備應安裝與額定功率相符的獨立電源開關，并有良好的接地線，個別石磨面粉機設備應根據說明書的要求配備穩壓電源。

All flour mill instruments shall be cleaned and restored in time after use to ensure the smooth progress of the next experiment. The electrical equipment shall be equipped with an independent power switch consistent with the rated power and have a good grounding wire. Individual stone mill flour mill equipment shall be equipped with regulated power supply according to the requirements of the manual.

使用儀器的相關人員應學習相應法律、法規及管理制度，所有操作人員應獲得資格證或經培訓合格才能進行儀器操作。對于玻璃儀器管理，應保持潔凈干燥，分類存放。

Relevant personnel using the instrument shall learn relevant laws, regulations and management systems, and all operators shall obtain qualification certificates or be trained to operate the instrument. Glassware management shall be kept clean and dry and stored by category.

玻璃儀器的洗滌很重要，一般應保證清洗潔凈透亮不掛水珠。一般應避免玻璃儀器直接加熱，確須加熱時，應使用石棉網緩慢均勻加熱，以免損壞器具，發生爆 炸，造成事故。在滴定管旋塞部位應涂抹凡士林，且要用橡皮筋系于漏斗頸上，避免滑出。這些都可以避免石磨面粉機器的磨損，有利于延長機械的壽命。

The washing of glassware is very important. Generally, it should be clean and bright without water droplets. Generally, direct heating of glass instruments shall be avoided. When heating is really necessary, asbestos mesh shall be used to heat slowly and evenly, so as to avoid damaging appliances, explosion and accidents. Vaseline shall be applied to the burette cock and tied to the funnel neck with a rubber band to avoid slipping out. These can avoid the wear of the stone flour machine and prolong the service life of the machine.
