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.
混用大小不同的氧化锆球,能否提供研磨效率?
答案是否定的,因为大小差异大的氧化锆球在高速运转的过程中 , 会产生以下问题:
(1) 由于重量不同 , 大球与小球容易产生分离现象 , 小磨珠容易被推挤到出料口处分离器出 , 造成严重研磨腔的局部液压上升 , 也会因推挤压力导致球与球之间产生的滚动不顺畅之现象。反而降了研磨效率,此现象将造成锆球的不正常损耗 , 更近一步因锆球的损耗变形 , 导致转子加速器销棒或盘片与内壁的不均匀磨耗。
(2) 大球重量大 , 冲撞力强 , 易导致小球的损坏、破裂与变形。
(3) 大、小球之间的切线间隙不同 , 在研磨过程中 , 根据液体流向定律,浆料的流动会倾向流往压力较低 , 剪切力较小的大球间隙而逃过被研磨。其结果是反而研磨浆料的粒径分布变得宽。
