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諾研NHE系列Disk盤式砂磨生產用途非常廣泛。轉子采用偏心盤設計,安裝在攪拌軸上,攪拌軸可以帶動整個研磨筒里的研磨介質旋轉,動態高效離器系統可很好地分離產品和研磨介質。帶有強冷卻的雙面機械密封,運行可靠,這確保了機器對于高粘性產品的良好運作。研磨細度可達2μm,根據物料的具體要求,研磨腔可按照不同的材料進行設計(如不銹鋼,聚氨酯,陶瓷,冷凍鑄造,硬質合金耐磨鋼)。
工作原理:
偏心盤按照一定順序安裝在攪拌軸上,物料在進料泵的作用下進入研磨腔,入口的設計是在驅動連接法蘭的一端,物料的流向與機械軸承向反底端一方,大大減輕了機械密封的承受壓力,延長其使用壽命,在攪拌軸偏心盤高速運轉中,物料和研磨介質的混合物發生高效相對運動,其結果,物料固體顆粒被有效分散、研磨,經一組轉子縫隙分離過濾器后,得到最終產品。
