石膏粉是怎么做的呢？今天來給大家普及這方面的知識，今天講的也是建筑工業用石膏粉。當然還有別的石膏粉，比如化工類石膏粉、模具類石膏粉以及食品類石膏粉。

How is gypsum powder made? Today, let's popularize this knowledge for everyone. Today, we will also talk about gypsum powder used in the construction industry. Of course, there are other types of gypsum powder, such as chemical gypsum powder, mold gypsum powder, and food gypsum powder.

　　建筑工業用石膏粉的制造，首先需要原料：天然石膏礦石、脫硫石膏、磷石膏。對于一般的項目流程生產可分四步：

The manufacturing of gypsum powder for the construction industry first requires raw materials such as natural gypsum ore, desulfurization gypsum, and phosphogypsum. For general project processes, production can be divided into four steps:

　　1、破碎環節

1. Crushing process

　　對石膏塊進行統一破碎處理，這里要注意輸料量和均勻輸送等要點。將破碎后的物料輸送到振動篩過篩，不能過篩的物料返回到破碎環節，直到全部過篩。

Unified crushing treatment should be carried out on gypsum blocks, and attention should be paid to key points such as material conveying volume and uniform conveying. Transport the crushed materials to the vibrating screen for screening, and return the materials that cannot pass the screen to the crushing process until they are all screened.

　　2、預粉磨環節

2. Pre grinding process

　　篩好的物料將分別進入干燥系統進行預烘干，烘干好的磷石膏經上料管和斗式提升機分別送到煅燒爐中。

The screened materials will be separately fed into the drying system for pre drying, and the dried phosphogypsum will be sent to the calcination furnace through feeding pipes and bucket elevators.

　　3、煅燒環節

3. Calcination process

　　進入煅燒爐中的烘干石膏粉，利用加熱裝置對其進行傳熱，將石膏粉內的水離子和部分結晶水脫除。然后，石膏粉在沸騰床的作用下成流化狀態，以自然溢出的方式，從各室流出，進行溫度化煅燒。最后得到優質建筑石膏粉。

The dried gypsum powder entering the calcination furnace is subjected to heat transfer using a heating device to remove water ions and some crystalline water from the gypsum powder. Then, the gypsum powder becomes fluidized under the action of a fluidized bed and flows out of each chamber in a natural overflow manner for temperature controlled calcination. Finally, high-quality building gypsum powder is obtained.

　　4、儲料輸送環節

4. Storage and transportation process

　　將制造好的石膏粉進行包裝運輸。
