Bottom up & Top down
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.

Horizontal Disk Grinding Machines
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.

Ceramic comminution chamber technology
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.
采用通过式研磨的主要原理：部分物料对粒度分布比较敏感，只需达到所需细度及体积比，因此采用此种研磨方式，只需控制研磨能量的输入和物料在研磨腔停留时间，并可得到所需的粒度分布要求
主要方式：固态颗粒在分散釜内搅拌或分散一定时间后，经过充分润湿通过进料泵投入到研磨腔中，为达到理想的粒度要求，特别是对颗粒度的细度或比表面积要求特别细的条件，经过多次的往复循环剪切，达到所需的产品性能..
主要面对的固态颗粒物料：如大批次、对D90、D50等粒度分布数据有要求，因现有的技术条件还无法满足在线粒度检测，需要研磨后立即进行检测，在检测的同时需要停机，此时研磨采用间歇式研磨比较合适。 
为在现较好的产品分布的一致性和产品线性扩大生产，在符合研磨工艺可达到所需要去的前提下，可串联一台、两台、三台等，改研磨方式可以保证所生产的产品高度的粒度分布一致性，从而保证了产品的性能。
