Density is an inherent property of matter, which plays a very important role in production and life. There are many and relatively simple methods to measure the density of large particulate matter. But the density measurement of fine-grained solid materials is difficult because of the volume measurement. Existing methods require expensive and complex equipment. In order to measure the density of fine solids in a simple, convenient, accurate and rapid manner, This paper uses water to fill the gap between the particles of materials, and then through the conversion of water mass and volume, so as to calculate the volume of materials, so as to calculate the density of fine-grained materials. This paper takes fine-grained phosphate ore as an example to demonstrate the application method of this study. The density of phosphate ore measured by this method is 2.84g/cm³ cubed, which is consistent with the theory. Steel ball and copper chip are also used for verification, and the calculated density is close to the theoretical density, which verifies the accuracy and reliability of this method. Through research and demonstration, this method can make it easy, fast and accurate to measure the density of fine solids, save time and investment, and improve efficiency and efficiency.
