石膏粉是怎么做的呢？今天来给大家普及这方面的知识，今天讲的也是建筑工业用石膏粉。当然还有别的石膏粉，比如化工类石膏粉、模具类石膏粉以及食品类石膏粉。

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.

　　建筑工业用石膏粉的制造，首先需要原料：天然石膏矿石、脱硫石膏、磷石膏。对于一般的项目流程生产可分四步：

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、破碎环节

1. Crushing process

　　对石膏块进行统一破碎处理，这里要注意输料量和均匀输送等要点。将破碎后的物料输送到振动筛过筛，不能过筛的物料返回到破碎环节，直到全部过筛。

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、预粉磨环节

2. Pre grinding process

　　筛好的物料将分别进入干燥系统进行预烘干，烘干好的磷石膏经上料管和斗式提升机分别送到煅烧炉中。

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、煅烧环节

3. Calcination process

　　进入煅烧炉中的烘干石膏粉，利用加热装置对其进行传热，将石膏粉内的水离子和部分结晶水脱除。然后，石膏粉在沸腾床的作用下成流化状态，以自然溢出的方式，从各室流出，进行温度化煅烧。最后得到优质建筑石膏粉。

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、储料输送环节

4. Storage and transportation process

　　将制造好的石膏粉进行包装运输。

Package and transport the manufactured gypsum powder.
