The manufacturing method
of magnesium powder
Magnesium powder is an important raw material for chemical production, which is widely used in plastics, rubber, ceramics, glass and other industries. This article will introduce the manufacturing method of magnesium powder, including raw material preparation, mixing, calcination, crushing, screening and other steps.

1. Raw Materials Preparation
The main raw materials for
strong magnesium powder are magnesium oxide and magnesium hydroxide. In order to ensure product quality, it is necessary to select raw materials with high purity and good activity. At the same time, quality inspection and control of raw materials are also required to ensure product stability and reliability.

2. mixing

mixing magnesium oxide and magnesium hydroxide in a certain proportion, and can be mixed by using a ball mill, a mixer and other equipment. During the mixing process, attention should be paid to controlling the mixing time and mixing uniformity to ensure the quality and stability of the product.

3. Calcination

The mixed material needs to be calcined to generate strong magnesium powder. Calcination temperature and time need to be determined according to the nature of the material and equipment. Generally speaking, the calcination temperature needs to be between 800-1000 ℃, and the calcination time needs to be determined according to the particle size of the material and the calcination equipment. During the calcination process, attention should be paid to the control of temperature and atmosphere to avoid defective products and environmental pollution.

4. Crushing

The calcined material needs to be crushed to obtain the desired particle size distribution. The pulverization can be carried out by using equipment such as a Raymont mill and an airflow mill. During the crushing process, attention should be paid to controlling the crushing particle size and output to avoid the problems of excessive crushing and insufficient production capacity.

5. sieving

The crushed material needs to be sieved to separate products of different particle sizes. Can use vibrating screen, rotary screen and other equipment for screening. During the screening process, attention should be paid to controlling the screen aperture and screening efficiency to ensure the particle size distribution and output of the product.

6. Packaging and Storage

The screened product needs to be packaged and stored to avoid moisture absorption and contamination. You can use plastic bags, paper bags and other packaging materials for packaging, storage needs to be placed in a dry, cool, ventilated place, avoid direct sunlight and high temperature environment.

In short, the manufacturing method of magnesium powder needs to go through multiple steps, including raw material preparation, mixing, calcination, crushing, sieving, etc. Each step requires strict control of process parameters and operating procedures to ensure product quality and stability. At the same time, it is also necessary to pay attention to environmental protection and safe production, abide by relevant laws, regulations and standards, and contribute to social development.
