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.

多數(shù)有機(jī)分子材料,對(duì)熱敏感,所有很多干法粉碎時(shí)動(dòng)需要通過(guò)低氮的引入對(duì)分子材料進(jìn)行降溫,防止其熱降解;同時(shí)濕法也適用于一些高分子材料的分散,如本身材料一次粒徑在納米級(jí),因本身帶電粒子的原因而團(tuán)聚,濕法研磨就是很好的解聚分散的方法之一。具體注意的細(xì)節(jié)如下:
1、控溫;
2、選擇合適的剪切力;
3、優(yōu)化設(shè)備和選項(xiàng),如納米棒銷式砂磨機(jī),選用較小鋯球適用于團(tuán)聚體的分散;
4、避免污染,在分散過(guò)程中盡量避免引入雜質(zhì),避免影響其性能。
5、控制粒度,可在分散過(guò)程中,加如在線粒度分析,可以很好的檢驗(yàn)細(xì)度和配方的優(yōu)劣。
6、后期干燥工藝的考慮。
