                              Dolomite and glass production

                              2018-10-16

                              Dolomite is one of the main magnesium minerals. The exploitation of dolomite can be divided into two types: blasting and shovel. In addition, it is also a natural soil conditioner. Dolomite is an important element in chemical fertilizers. Dolomite can change the soil from acidic to alkaline and give soil nutrients, which is conducive to the cultivation of crops.
                              Dolomite is one of the raw materials for glass production. High quality dolomite is one of the prerequisites for producing high quality glass. The granularity of dolomite has great influence on glass production. We should pay attention to several points in the production process. First, eliminate large dolomite particles. The reason for the emergence of large particles is that there are holes in the bottom of the sieve and cause particles to splash. This large particle will seriously affect the quality of glass. Therefore, the granularity of dolomite must be strictly checked in the process of dolomite treatment. Second, strict control of water. This can, to some extent, avoid the problem of screen hole blockage and improve screening efficiency. Third, prevent iron from mixing and strengthen iron removal during dolomite treatment. Machine wear will lead to an increase in iron content in dolomite materials, so it is necessary to reduce the amount of mechanical iron in dolomite products.
                              The reasonable particle size composition of dolomite is also necessary. Reasonable composition is beneficial not only to the mixing of the mixture, but also to the melting efficiency. Dolomite with large granularity hinders the decomposition of carbonate and the formation of carbonate compound salts. However, if the dolomite granularity is too small, it will reduce the reaction rate of silicate. Small particles produce many bubbles at the initial stage of melting, which makes it difficult for thermal radiation to enter the molten glass.
                              As you can see, dolomite has wide application in various industrious fields. In order to guarantee its usage, dolomite grinding machine must play a role. In general, there are two main types of dolomite powder processing machines in the market. One is Dolomite Raymond mill, the other is dolomite ultra-fine powder grinding machine. Raymond mill usually performs well in its steady operation. Dolomite ultra-fine grinding mill has adopted the advanced intelligent speed control device. Dolomite ultra-fine machine also called HGM micro powder machine in our company. The specification of this mill can be seen in the following table.
