At present, there are 91 kinds of non-metallic minerals, The main minerals can be divided into gypsum mining area, refractory raw materials, fluorite mineral, wollastonite, sulfur ore good source, diatomite, etc, the mineral resources of medium salt are also quite abundant. These non-metallic mineral raw materials can be used with higher value after being processed and milled by a professional grinder, and the equipment technology of the grinder is also quite mature.
Non metallic ore equipment processing and grinding process flow:
1. Open circuit grinding process: after the material passes through the mill, it becomes a finished product. The process is relatively simple, the number of equipment is small, and the customer needs to invest less, but it is easy to produce excessive grinding in the process.
2. Closed circuit grinding process flow: after the non-metallic ore raw materials are grinded, the products need to be sorted out by the sorter system, and the coarse raw materials that do not meet the grain size requirements are returned to the mill for regrinding. This process reduces excessive grinding, increases output and reduces power consumption. The fineness of the product is easy to control. The disadvantage of this process is that it is difficult to operate and maintain due to large equipment investment. However, SMMVIK Machinery provides you with better solutions, which can be safely used.
In terms of several types of grinding machines of SMMVIK Machinery, LM vertical grinding machine is a relatively automatic control slag grinding process for processing non-metallic mineral raw materials, such as slag powder production line. The fineness of the manufactured powder is relatively stable, generally in the range of 400-650mm. The particle distribution is reasonable and the quality stability is good. The mixing process and ton packaging process, SMMVIK Machinery vertical mill has a large capacity, leaving enough space for the grinding of internal materials. The grinding efficiency and grinding speed are greatly improved compared with the general mill. With the continuous maturity of vertical grinding technology, the mineral processing equipment for non-metallic ores will be left to vertical mills.
