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.
目前國內的氧化鋯珠品質參差不齊,諾研臥式砂磨機屬于高能量輸入、高剪切研磨設備,線速度可達10m-20m/s,國產普通的研磨介質一般都會被磨碎,建議用日本、新加坡或法國進口氧化鋯珠。

→研磨珠質量越大,提供研磨剪切力越大;
|
→單個研磨珠尺寸越大,提供研磨剪切力越大;
|
→單位體積研磨珠數量越多,碰撞點越多,研磨效率越高;
|
→對于一個研磨體系,我們必須考慮合適的研磨珠比重、粒徑,并且要考慮到設備的配套性。

→是否有可控穩定的物理指標
→是否有可控的晶相含量;
→是否有完善的的晶?刂
→是否有完美的內部結構
