Comparison between granular magnesium oxide and powdered magnesium oxide

Granular magnesium oxide and powdery magnesium oxide look just different in appearance and shape. They are both made of magnesium oxide as raw material. However, due to the different advantages and disadvantages of these two kinds of magnesium oxide, their application sites are also different.


In the process of tablet pressing, the material is not granulated, but directly compressed by magnesium oxide powder, which has many outstanding advantages, such as time-saving and energy saving, simple process, reduced process, and applicable to unstable drugs under hot and humid conditions. However, the direct compression of magnesium oxide powder has some weaknesses, such as poor powder fluidity, large difference in sheet weight and easy to cause cracks, which limits the application of this process.

In the process of storage and transportation, due to the different bulk density of various powder raw materials, classification will occur. Granular magnesium oxide does not produce dust, and the environmental pollution rate is reduced to a low level. During production, it is not easy to produce dust, which can protect the respiratory system of production personnel. In terms of volume, powdered magnesium oxide will produce some dust, which will adhere to the four walls of the transport container. Granular magnesium oxide is free of dust, adhesion and economy. Granular magnesium oxide can also have special granulators or molds for different industries, such as 20 mesh – 80 mesh, 60 mesh – 100 mesh, etc.

Hebei Messi Biology Co., Ltd. said that granular magnesium oxide and powdered magnesium oxide have their own advantages and disadvantages. The specific form of powder or particle, as well as the particle size of crushing, depends on the customer\’s production process equipment and production costs.
