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.

砂磨機在研磨過程中,會產生大量的熱量,對漿料的性質和設備本身會產生較大的影響,主要通過以下手段去降低發(fā)熱量:
首先砂磨機容易發(fā)熱的部位有:機械密封、研磨腔定子夾套、出料口、驅動軸承等。機械密封需如果過熱,密封中的O型密封圈會變形失效,合金環(huán)壽命會降低,會導致整體密封效果不好泄漏,特別是加入溶劑冷卻液時,會直接污染研磨腔內的漿料,嚴重導致漿料報廢,所以需要再冷卻罐內增加換熱器同時降低冷媒溫度,同時加大流量。
研磨腔夾套冷卻:研磨腔定子熱是由研磨介質和漿料的摩擦產生的,該位置的冷卻可以大大降低漿料的溫度,使?jié){料研磨時在合理有效的溫控范圍內被物理細化,可以通過加冷媒大循環(huán)流量和溫度來降低漿料的溫度,同時也可以考慮在不影響材料純度的前提下,更換導熱系數(shù)更好的材料。
出料口溫度過高,可以通過向出料口內置換熱管來實現(xiàn)降溫。
軸承溫度過高,可以調整軸承的品牌、更換合適的潤滑脂、加大軸承箱的導熱面積來解決。
