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.
→更换珠子主要是由于珠子磨损,造成其体积质量的减少,对产品的质量造成很大的影响
→珠子大小的选用是于定子和转子分离环间的间隙决定的。而当珠子直径与间隙接近到一定程度时就应更换,如norwa盘式砂磨机,选用的珠子为1.8mm,而分离环间隙为0.5mm,当最小的珠子小于1.2mm时就因更换所有的珠子
→当我们在出料口发现了有珠子的碎片时,也应全部更换
→当珠子的直径仍在容许范围时,可以使用或直接添加新珠
