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.
在各国碳中和目标之下,光伏产业迎来新一轮倍速发展,这吸引了众多掘金者跨界涌入光伏制造业,过去十年,光伏是度电成本下降最快的能源品种。由中国企业主导的技术创新下,光伏发电度电成本十年间累计下降近90%,中国光伏行业持续保持产业规模全球第一、生产制造全球第一、技术水平全球第一的领跑地位。截至2020年,在光伏制造端,中国企业在多晶硅、硅片、电池片、组件四个主要环节的产量占全球产量的比例均超过2/3。
单晶是未来度电成本最低的技术路线,ATO薄膜组成元素地壳储量丰富、价格便宜且无毒环保,是目前备受关注的ITO薄膜替代材料之一,采用磁控溅射法制备ATO薄膜,研究各个工艺参数比例与可见光透过率、电阻率之间的相互作用机理,优化其光、电学性能,并实现ATO薄膜电极在CZTS和Sb2Se3薄膜太阳能器件中的应用。
