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
物料随着进料泵由顶端进入研磨腔,随着转子的旋转而均匀分布,在转子和定子缝隙内涡流离心力的作用下对物料进行了彻底的预分散处理。在接下来强烈的研磨中,转子棒销和定子对研磨介质连续发生剧烈的撞击变化,研磨介质再作用于物料,物料得以研磨,研磨后的物料在研磨腔停留时间特别短,从而得到一个极窄的产品粒度分布带,在进料泵压力和离心力作用下,由于密度的不同,研磨介质返回研磨腔,物料却沿着离心力相反的方向经动态分离器过滤分离,循环往复。
结构设计:核心设计转子上安装有进口耐磨钢棒销,数量和体积、安装位置按涡流体力学设计,达到合适研磨比研磨能量,提高物料研磨效率,使物料研磨细度达到纳米级,经第三方马尔文激光粒度测试仪测定,细度可达≤30nm。
