1. Magnesite
The magnesium content of the raw magnesite ore mined by our factory reaches more than 46%. Advanced crushing equipment is used to crush the raw ore into a uniform size block and enter the reflection cellar, which reduces the over-burning rate and under-burning rate of the product and ensures that the The processed magnesium oxide content of the finished product is above 85%. The magnesite is manually screened to separate the ore containing other impurities. Haicheng magnesium oxide enhances the safety and stability of the product.
2. Fuel
Select high-quality coal and sign long-term purchase and sales contracts with state-owned coal manufacturers, which not only ensures the quality of the fuel, but also stabilizes the price of the fuel.
