In the case of a certain amount of ore, the size of the flushing at the discharge port and the size of the ore directly affect the fineness of the grinding. In many domestic mines, the grinding automation is not realized, and the amount of water is directly carried out by the ball miller. Manual adjustment, because the water flow in these two places is large, it is difficult to see the increase and decrease, so careful observation and fine adjustment must be required. First of all, we understand that the ball mill water supply increases, the grinding concentration becomes thinner, and the grinding fineness becomes coarser. On the contrary, the ball mill water supply decreases, the grinding concentration becomes larger, and the grinding fineness becomes finer. The flushing water at the discharge port of the ball mill becomes larger, the overflow becomes thinner, and the overflow fineness becomes finer. On the contrary, the flushing water at the discharge port of the ball mill becomes smaller, the overflow becomes thicker, and the overflow fineness becomes thicker. Therefore, in other conditions, including the same amount of minerals, to improve the fineness of grinding, the ball mill water supply can be reduced, and the flushing water at the ball mill discharge port is increased. It is best to adjust these two conditions at the same time to ensure The fluctuation of the flotation is caused by the change in the amount of the ore caused by the adjustment of the fineness of the grinding. In many processing plant because workers milling operations, the amount of ore oar cause larger changes, resulting in an unstable liquid flotation, flotation work if not treated, it causes a variation in metal recovery and grade. The opposite is true if the fineness of the grinding is coarsened. Under the premise of grinding fineness guarantee, the amount of ore given by the ball mill can be increased. The size of the ore is given to meet the grinding fineness requirements, while the ball mill does not swell. The entire process must be carried out in detail in all aspects. 110-91-8,N-Methyl Morpholine,C4H9NO,Diethylenimide Oxide Identifiers,O(CH2CH2)2NH,1-Oxa-4-azacyclohexane,Tetrahydro-1,4-oxazine,Drewamine,Diethylene imidoxide Jinan Forever Chemical Co., Ltd. , https://www.jinanforever.com
Uses
Industrial applications
Morpholine is a common additive, in ppm concentrations, for pH adjustment in both fossil fuel and nuclear power plant steam systems. Morpholine is used because its volatility is about the same as water, so once it is added to the water, its concentration becomes distributed rather evenly in both the water and steam phases. Its pH adjusting qualities then become distributed throughout the steam plant to providecorrosion protection. Morpholine is often used in conjunction with low concentrations of hydrazine orammonia to provide a comprehensive all-volatile treatment chemistry for corrosion protection for the steam systems of such plants. Morpholine decomposes reasonably slowly in the absence of oxygen even at the high temperatures and pressures in these steam systems.
Organic synthesis
Morpholine undergoes most chemical reactions typical for other secondary amines, though the presence of the ether oxygen withdraws electron density from the nitrogen, rendering it less nucleophilic (and less basic) than structurally similar secondary amines such as piperidine. For this reason, it forms a stable chloramine (CAS#23328-69-0).
It is commonly used to generate enamines.
Morpholine is widely used in organic synthesis. For example, it is a building block in the preparation of the antibiotic linezolid and the anticancer agent gefitinib
Morpholine is used as a chemical emulsifier in the process of waxing fruit. Fruits make waxes naturally to protect against insects and fungal contamination, but this can be lost by means of the food processing companies when they clean the fruit. As a result, an extremely small amount of new wax is applied and morpholine is then added and used as an emulsifier to evenly coat a fruit with the wax.
In research and in industry, the low cost and polarity of morpholine lead to its common use as a solvent for chemical reactions.
As a component in fungicides
Morpholine derivatives used as agricultural fungicides in cereals are known as Ergosterol Biosynthesis Inhibitors.
