A special agitator shaft with symmetrically arranged agitator pegs and sleeves of tungsten carbide for wear protection devel- Vertical, batch operation mill for the preparation of tungsten Ideal flow behaviour due to a special agitator peg arrange-ment and the hemispherically shaped chamber floor integrated screen plate for grinding media separationIntensive cooling through a double-wall grinding tank and cooled circulation pipeline
Product inlet via rotor / immersion tube system prevents back flow of grinding media into the feed line.
Generally, there are two ways to obtain nano-powders. A bottom-up manufacturing method (bottom up) for chemical methods, such as chemical precipitation, sol-gel process (sol-gel),... Another method is physical method, which changes the powder particles from big to small (top down), such as mechanical ball milling,... And so on.
The Development In 1963, the first vertical agitator was developed internationally, the first horizontal agitator was developed in 1975, the first horizontal agitator bead mill with eccentric disks was introduced to the public and the horizontal disc grinder was introduced, in 2004, which became the industry standard. In the following years, the grinding media separation systems, the geometry of the grinding disks and the various grinding chamber materials were further developed.
The grinding system pin nanomill shows the evolutionary develop- ment of system with the rotor-slotted pipe separating system. The enclosed horizontal agitator mill is designed for highest product throughput rates and possesses a pin grinding system for highest grinding intensity.
In 2011, we developed the first zirconia comminution chamber technology in China. It has no metal ion pollution and is used in batteries, pharmaceuticals, glazes, ink and food.
磷酸鐵鋰電池的全名是磷酸鐵鋰鋰離子電池,這名字太長,簡稱為磷酸鐵鋰電池。由于它的性能特別適于作動力方面的應用,則在名稱中加入“動力”兩字,即磷酸鐵鋰動力電池。也有人把它稱為“鋰鐵(LiFe)動力電池”。
結構與工作原理。LiFePO4作為電池的正極,由鋁箔與電池正極連接,中間是聚合物的隔膜,它把正極與負極隔開,但鋰離子Li可以通過而電子e-不能通過,右邊是由碳(石墨)組成的電池負極,由銅箔與電池的負極連接。
電池的上下端之間是電池的電解質,電池由金屬外殼密閉封裝。LiFePO4電池在充電時,正極中的鋰離子Li通過聚合物隔膜向負極遷移;在放電過程中,負極中的鋰離子Li通過隔膜向正極遷移。鋰離子電池就是因鋰離子在充放電時來回遷移而命名的。
