Crushing and grinding of electrodeposited manganese dioxide
Electrolytic manganese dioxide, for use as an efficient depolarizer in dry cells, is produced by the electrolysis of a solution of manganese sulphate and sulphuric acid at a temperature of 95°C. As the electrolysis proceeds, manganese dioxide is deposited in thick adherent form on the anodes. The anodes are taken out when the deposited manganese dioxide attains a thickness of 15-25 mm in about 10-15 days on continuous operation. The thickness of the EMD deposited on the anode depends on the current density and the duration of electrolysis. The anodes after taking out of the electrolytic cells are washed thoroughly with water to remove the carried over electrolyte and hot air dried. The sudden fluctuation in temperature, on lifting the anodes from the hot electrolytic cell and washing, cracks the EMD deposit. After drying, the deposits are easily stripped from the anodes by mild striking.
The stripped manganese dioxide deposits are in flake form. This has to be crushed and ground to —200 mesh/-325 mesh according to the requirements of the customers without contamination of iron, alumina, silica or any other impurities since these will bring down the Mn02 content of the product to lower levels and the activity of the EMD for dry cell applications will fail down. Thus the crushing and grinding of electrodeposited manganese dioxide is one of the most important process steps in the production of EMI).
Manganese grinding mill
For additional manganese ore grinding, there is manganese grinding mill, like ball mill, manganese mill, etc. MTM medium speed T rubs with the standard vertical grinding machine compares to have the incomparable superiority, applies many national newest grinding machine patented technologies, the contemporary design and structure are reasonable, the area is small, electrical energy consumes, the service life lowly lengthy, and vulnerable construction price is low, performance-to-price ratio greater characteristic.
