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.
研磨介质氧化锆的材料密度所代表的意义为材料的致密性. 致密性高, 一般氧化锆陶瓷的密度≥6.0g/cm3,材料的特性才能有较好的发挥. 致密性低, 意味孔洞多, 或纯度不良, 介质耐磨性便不佳, 研磨的污染率就相对提高。填充密度的定义为每立方体积的介质重量 除了用来计算研磨机中介质的填充量之外, 介质的材料密度 : 如上所述, 材料密度不良, 耐磨性差, 充填密度相对低。以下为某国产锆珠60小时和日本YTZ进口锆珠同等条件下水磨后的图片(左边为国产锆球、右边为日本锆球)
