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.
二氧化硅材料来源广泛,SI-O-SI健的特性决定了他的化学性质稳定,价格低廉、耐腐蚀、耐高温、绝缘性好等特点。纳米二氧化硅颗粒是采用纯物理法,砂磨机研磨得到的一种无毒、无味、无污染的小尺寸、大比表面积的无机非金属材料,在扫描电镜显示下呈现絮状或网状准颗粒结构,广泛应用于如下领域:
陶瓷领域:添加进陶瓷材料里,可以大大降低陶瓷制品的脆性,增加其韧性。
涂料领域:二氧化硅具有抗紫外辐射,添加到涂料中可以提高涂料的稳定性、耐候性和防触变能力,大大增加涂料涂磨与介质的结合能力。
催化领域:可以作为非均相催化剂使用,提高催化剂载体表面的性质和结构。
环境保护:因纳米二氧化硅具有较大的比表面积,特殊的官能团经过表面修饰后可以吸附有害物质。
生物医药:纳米二氧化硅具有生物相容性和低毒性,在药剂中适量添加可以提高药物的吸收性,改善分散性,可作为基因载体、生物传感使用。
其他:也可作为造纸行业的增强白度、强度,作为消光剂,可以应用在彩色喷墨打印,提高打印质量,缩小墨点面积等
