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.
NORVA尊龙凯时官网NHE系列Disk盘式砂磨生产用途非常广泛。转子采用偏心盘设计,安装在搅拌轴上,搅拌轴可以带动整个研磨筒里的研磨介质旋转,动态高效离器系统可很好地分离产品和研磨介质。带有强冷却的双面机械密封,运行可靠,这确保了机器对于高粘性产品的良好运作。研磨细度可达2μm,根据物料的具体要求,研磨腔可按照不同的材料进行设计(如不锈钢,聚氨酯,陶瓷,冷冻铸造,硬质合金耐磨钢)。
工作原理:
偏心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,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,得到最终产品。
