The construction of the green mine has become a national action. If the allocation scheme of the sandstone production line is unreasonable, it is easy to produce a large amount of dust in the production process, which pollutes the environment and is not conducive to the development of green environmental protection. In the sandstone processing system, the artificial sand production capacity is about 460 t / h, and the materials treatment capacity is about 1000 t / h. The powder separator widely used in cement production is applied to the sand and stone system production by using the full dry sand processing technology, and the adjustment is made according to the actual working conditions to meet the needs of aggregate processing quality and environmental protection. What should be done to prevent dust in the sand aggregate production line? Taking the processing technology of lithium mine as an example.
Lithium Ore Processing Equipment
Lithium ore is a kind of metal ore formed by a chemical reaction in sedimentary rocks for a long time. The comprehensive utilization value of this mine is very high, and it is used as a high-end metal in the chemical industry, metallurgy, aerospace and other fields, which plays a vital role in the development of modern science and technology.
For the processing of lithium ore, in addition to using separate equipment for processing operations, but also can use lithium ore processing technology for production and manufacturing. However, facts fully prove that lithium ore produced by lithium ore processing technology is easier to meet the actual needs of users. The lithium ore processing process requires a lot of equipment；systematically speaking, it has three types of equipment: crushing equipment, grinding equipment, flotation equipment. On this basis, some auxiliary devices are also added.
Dust Prevention Measures of Lithium Mine Processing Technology
1. Dust reduction and dust control in material yard mining
The blasting parameters are optimized, and the dust removal rig or dust cover is used to meet the production demand of the system. According to different blasting tests, the blasting parameters are determined. While controlling the wool particle size, it is also necessary to analyze the powder formation rate of the wool after the change of each blasting parameter in order to control the stone powder content of the original sand.
2. In order to achieve the effect of material matching and crushing, the problem of poor gradation of sand and great fluctuation of fineness modulus can be solved to a certain extent by consciously mixing material with fillers in different areas.
Dust Reduction Measures of the Sandstone Processing System
1. The first kind of equipment needed for lithium mine processing is crushing equipment. According to the characteristics and processing technology of lithium mine, jaw crusher and cone crusher are selected for primary and secondary crushing of lithium mine. When the content of the stone powder reaches more than 40% after the crushing of the crusher, the strong vibration and the high drop will cause the dust to rise and affect the working environment. Therefore, the invention has various improvement measures on the dustproof of the system and has achieved certain results, so that the discharge diameter of the lithium ore can be smoothly entered the ball mill, thereby ensuring the smooth operation of the whole process.
2. Humidification and high altitude atomization of the system production line, the dust formed by material impact can be reduced by humidifying and atomizing the material at high altitude when the water content permits.
