In modern industry, main use of dolomite includes: building stones, refractory bricks for furnace linings, ornamental stone, ore of metallic magnesium. Besides, dolomite is chosen for many construction and building applications due to its increasing hardness and density. Dolomite also finds use in a number of applications as a source of magnesium such as glass and ceramics manufacture, as well as a sintering agent in iron ore pelletization and as a flux agent in steel making. Farmers use dolomite for agricultural pH control. Due to its wide applications, many sectors have a great demand for dolomite. Accordingly, the price of dolomite powder is ever rising. Many investors decide to get profits in the dolomite industry. And they purchase sets of dolomite processing machine and line around the world. In the next year, the price of domolite products will remain growing. Therefore, it is a wise choice for investing in the dolomite industry.
Overview of Dolomite Processing Flowchart
As for processing dolomite, it mainly consists of two important mining stage, that is crushing and grinding. The hardness of dolomite ranges from 3.5 to 4.5 Mohs. To get a good crushing efficiency, it needs two crushing stages, including the primary crushing and secondary crushing stage. Typically, jaw crusher is used during the primary crushing stage, and the impact crusher is used during the secondary crushing stage. After the two stages,large dolomite rock whose diameter is approximately 1.5 meters has changed into dolomite particle, and the size of dolomite particles can achieve to 25mm or less. To produce dolomite powder, the grinding mill is a necessary machine. Types of grinding mill are varied, including the ball mill, Raymond mill, vertical mill, trapezium mill, coarse powder mill, and ultrafine mill, etc.
Dolomite Processing Machine and Line
Dolomite processing machines can be divided into dolomite crsuhing machine and grinding machine. As for the selection of dolomite crushing machines, specialists from Zenith suggest using the PE series jaw crusher and PFW series impact crusher, which features high efficiency, high capacity, reliable performance and low operation cost. As for the selection of dolomite grinding mill, specialists from Zenith suggest the LM Series vertical mill is the best choice. It is equipped with an automatic control device, which can ensure the remote control, making the operation easier than traditional vertical mill. Besides, the LM Series vertical mill is sealed, when the whole system is working under the negative pressure, there is no powder overflow.
