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.
目前国内的氧化锆珠品质参差不齐,德赢vwin卧式砂磨机属于高能量输入、高剪切研磨设备,线速度可达10m-20m/s,国产普通的研磨介质一般都会被磨碎,建议用日本、新加坡或法国进口氧化锆珠。

→研磨珠质量越大,提供研磨剪切力越大;
|
→单个研磨珠尺寸越大,提供研磨剪切力越大;
|
→单位体积研磨珠数量越多,碰撞点越多,研磨效率越高;
|
→对于一个研磨体系,我们必须考虑合适的研磨珠比重、粒径,并且要考虑到设备的配套性。
