During grinding, the balls themselves wear and are continuously replaced by new ones so that mill contains balls of various ages. Ball mill produces 1 to 50 ton/hr of powder and energy requirement of the ball mill is about 16 kwh/ton.
WhatsApp: +86 18838072829Ball milling: Pieces of lead are put into a rotary mechanical mill, forming fine lead flakes, which are then oxidised in air and removed. This also gives 75 80% lead oxide. Red lead (Pb 3O 4) can also be added to the PbO formed by these methods, as it is more conductive. This is produced from PbO by roasting in a flow of air.

The torque increases slowly until the peak is attained around N=80%.As the amount of cataracting increases, the balance of the charge improves and the torque required to maintain the asymmetric charge position declines steadily.
WhatsApp: +86 18838072829The present invention relates to a method for preparing nitride of litium metal by a ball milling method; a lithium battery is used as a negative electrode material. The present invention is characterized in that lithium nitride powder and metal powder are proportionally and uniformly mixed under the condition of inert gas according to a general formula of Li<3X>M
At present, the battery industry makes leady oxide by either the ballmill or the Bartonpot process. It is difficult to conclude which of the two methods gives the best leady oxide. Each...
