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.
高純度氧化鋯陶瓷粉主要應用于醫院領域牙科材料,醫院常用的烤瓷牙就是采用高純度氧化鋯粉燒結而成,避免帶人金屬離子而導致病人炎癥的產生,要得到高純度氧化鋯粉需要采用以下濕法研磨措施:
1.D99細度要小于1微米,避免大顆粒導致澆模和燒結時產生裂紋;
2.納米砂磨機研磨后的氧化鋯粉的純度要達到99.999%,俗稱5個9.
3.研磨腔接觸物料部分必須采用氧化鋯陶瓷轉子、內襯、端蓋,甚至機械密封也要改成氧化鋯陶瓷的;
4.輸送管道必須采用PTFE或聚氨酯材質,避免金屬離子的帶入;
5.輸送泵需要采用美國進口英格索蘭的聚四氟塑料泵;
6.車間需要達到食品級標準。
7.出料后必須除磁除鐵等金屬離子工藝。
