(1) The storage site for carbon raw materials must be a cement floor, and the mixing of external impurities should be minimized when storing raw materials.

(2) During the storage of raw materials, it is strictly prohibited to mix dust, sediment, and other impurities. It is best to store low ash materials in storage, and urgently needed raw materials should be kept in stock. For spare raw materials, if there is no warehouse for storage, they can also be stored outdoors, but management must be strengthened and appropriate measures must be taken.

(3) During the storage period, carbon raw materials should be prevented from mixing with each other, especially to prevent more ash raw materials from mixing with less ash raw materials. If the raw materials are mixed, they should be downgraded for use. For the same type of raw materials, if the quality inspection results differ significantly, they should be stacked separately.

(4) To prevent rain and snow from soaking in raw materials, it is necessary to prevent them from increasing their moisture due to rainwater or snow infiltration, which can affect the degree of heat treatment during the calcination or drying process and increase fuel consumption.

(5) Pay attention to the turnover and use of stored new and old raw materials, and some raw materials should not be stored for too long.

(6) We need to strengthen the quality inspection of stored raw materials in order to timely grasp the changes in the quality of stored raw materials. If the quality of stored raw materials changes beyond the requirements, they should be stopped from use.
