What are the uses of magnesite? In fact, magnesite is both an important source of industrial magnesium and a common raw material for alkaline refractories. It's all about magnesium. Here we will introduce you to the specific uses of magnesite and how it is processed.

More than 85% of China's magnesite reserves are located in Liaoning, followed by Shandong, which is mainly located in the Dashiqiao - Haicheng area, and thus there are more refractory production enterprises in the region. Magnesite is a magnesium carbonate mineral, gray or off-white in color, with a hardness of 3.5 to 4.5 and a specific gravity of 2.9 to 3.1.What are the uses of magnesite, as mentioned before, it is the most important mineral source for industrial refining of magnesium. As industry continues to develop, the demand for magnesium metal and magnesium compounds continues to grow, making it increasingly important to fulfill its value. Magnesia sand is also used as a basic basic refractory material for the production of magnesium bricks, chrome magnesium bricks, magnesia sand and magnesium crucibles. Lightly burnt magnesium produced from magnesite sand can also be used in cement construction, ceramics, pharmaceuticals, rubber, man-made fibers, paper making and other industries.

However, with the depth of magnesite mining, high-grade magnesite is less and less, which requires the purification of low-grade magnesite. Usually use flotation, light burning, thermal separation, re-election, chemical method. Today we mainly talk about the method of light burning. It is 20-100 mm magnesite in 750-1100 ℃ forging, after forging magnesite in the magnesium oxide content can be doubled, greatly improving the ore grade. Re-election and hot selection should be lightly burned. Lightly burned magnesium powder can be obtained by grinding and second forging.

According to the different downstream products, the fineness of the light-fired magnesium powder has some differences, the common ones are 80 mesh, 100 mesh, 120 mesh, 180 mesh, 250 mesh, 325 mesh and so on. Magnesium sand grinding machine is mainly used for light burnt magnesium grinding machine. LIMING HEAVY INDUSTRY LM Vertical Mill, which can process light burnt magnesium alloy with high efficiency and environmental friendly. It can be adjusted to different grain size by adjusting the speed and velocity of the granulator, which is easy to operate. The whole system operates under negative pressure with good sealing performance, and the discharged gas is dust-free, which meets the requirement of environmental protection.
