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.

氧化鋯球作為砂磨機(jī)使用中不可分割的一部分,在砂磨機(jī)研磨細(xì)化過程中起著關(guān)鍵作用,氧化鋯球的主要成份:其中氧化鋯約占比95%,氧化釔占比約5%,所以市場又通俗稱為“95鋯”
氧化鋯球或氧化鋯珠更換周期主要由以下因素決定的:
1、氧化鋯球的品質(zhì),主要由磨耗、球形度、原料晶體結(jié)構(gòu)等決定;
2、氧化鋯球的尺寸,一般尺寸越大相對(duì)使用壽命越長,但特殊的小尺寸的鋯球如0.1mm、0.2mm使用壽命也很長,這與其研磨中主要起分散作用有關(guān)。
3、原料粒度、硬度;
4、分離器過濾精度;
5、碎珠產(chǎn)生,當(dāng)有一定比例的碎球或橢圓形產(chǎn)生時(shí),需要考慮更換或補(bǔ)充鋯球;
6、研磨效率,當(dāng)發(fā)現(xiàn)研磨效率發(fā)生下降時(shí),可以考慮更換氧化鋯球;
如發(fā)現(xiàn)研磨機(jī)的研磨效率降低,是添加珠子的可能信號(hào)。用戶可依本身的工藝條件,掌握珠子的實(shí)際的損耗率,而作定期的篩珠和添加,一般經(jīng)驗(yàn)指數(shù)當(dāng)球徑磨損約40%時(shí)需要更換或補(bǔ)充。
