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.

二氧化硅材料來源廣泛,SI-O-SI健的特性決定了他的化學(xué)性質(zhì)穩(wěn)定,價(jià)格低廉、耐腐蝕、耐高溫、絕緣性好等特點(diǎn)。納米二氧化硅顆粒是采用純物理法,砂磨機(jī)研磨得到的一種無毒、無味、無污染的小尺寸、大比表面積的無機(jī)非金屬材料,在掃描電鏡顯示下呈現(xiàn)絮狀或網(wǎng)狀準(zhǔn)顆粒結(jié)構(gòu),廣泛應(yīng)用于如下領(lǐng)域:
陶瓷領(lǐng)域:添加進(jìn)陶瓷材料里,可以大大降低陶瓷制品的脆性,增加其韌性。
涂料領(lǐng)域:二氧化硅具有抗紫外輻射,添加到涂料中可以提高涂料的穩(wěn)定性、耐候性和防觸變能力,大大增加涂料涂磨與介質(zhì)的結(jié)合能力。
催化領(lǐng)域:可以作為非均相催化劑使用,提高催化劑載體表面的性質(zhì)和結(jié)構(gòu)。
環(huán)境保護(hù):因納米二氧化硅具有較大的比表面積,特殊的官能團(tuán)經(jīng)過表面修飾后可以吸附有害物質(zhì)。
生物醫(yī)藥:納米二氧化硅具有生物相容性和低毒性,在藥劑中適量添加可以提高藥物的吸收性,改善分散性,可作為基因載體、生物傳感使用。
其他:也可作為造紙行業(yè)的增強(qiáng)白度、強(qiáng)度,作為消光劑,可以應(yīng)用在彩色噴墨打印,提高打印質(zhì)量,縮小墨點(diǎn)面積等
