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.
采用通過式研磨的主要原理：部分物料對粒度分布比較敏感，只需達到所需細度及體積比，因此采用此種研磨方式，只需控制研磨能量的輸入和物料在研磨腔停留時間，并可得到所需的粒度分布要求
主要方式：固態顆粒在分散釜內攪拌或分散一定時間后，經過充分潤濕通過進料泵投入到研磨腔中，為達到理想的粒度要求，特別是對顆粒度的細度或比表面積要求特別細的條件，經過多次的往復循環剪切，達到所需的產品性能..
主要面對的固態顆粒物料：如大批次、對D90、D50等粒度分布數據有要求，因現有的技術條件還無法滿足在線粒度檢測，需要研磨后立即進行檢測，在檢測的同時需要停機，此時研磨采用間歇式研磨比較合適。 
為在現較好的產品分布的一致性和產品線性擴大生產，在符合研磨工藝可達到所需要去的前提下，可串聯一臺、兩臺、三臺等，改研磨方式可以保證所生產的產品高度的粒度分布一致性，從而保證了產品的性能。
