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.
工作原理:
NORVA诺研高效亚微米卧式砂磨机采用先进的三偏心凸轮盘按照一定顺序安装在搅拌轴上,物料在进料泵的作用下进入研磨腔,入口的设计是在驱动连接法兰的一端,物料的流向与机械轴承向反底端一方,大大减轻了机械密封的承受压力,延长其使用寿命,在搅拌轴偏心盘高速运转中,物料和研磨介质的混合物发生高效相对运动,能量传递稳定无死角,其结果,物料固体颗粒被有效分散、研磨,经一组转子缝隙分离过滤器后,得到一个较窄正态粒度分布优质产品。 |
