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.
工作原理
物料隨著進(jìn)料泵由頂端進(jìn)入研磨腔,隨著轉(zhuǎn)子的旋轉(zhuǎn)而均勻分布,在轉(zhuǎn)子和定子縫隙內(nèi)渦流離心力的作用下對(duì)物料進(jìn)行了徹底的預(yù)分散處理。在接下來強(qiáng)烈的研磨中,轉(zhuǎn)子棒銷和定子對(duì)研磨介質(zhì)連續(xù)發(fā)生劇烈的撞擊變化,研磨介質(zhì)再作用于物料,物料得以研磨,研磨后的物料在研磨腔停留時(shí)間特別短,從而得到一個(gè)極窄的產(chǎn)品粒度分布帶,在進(jìn)料泵壓力和離心力作用下,由于密度的不同,研磨介質(zhì)返回研磨腔,物料卻沿著離心力相反的方向經(jīng)動(dòng)態(tài)分離器過濾分離,循環(huán)往復(fù)。
結(jié)構(gòu)設(shè)計(jì):核心設(shè)計(jì)轉(zhuǎn)子上安裝有進(jìn)口耐磨鋼棒銷,數(shù)量和體積、安裝位置按渦流體力學(xué)設(shè)計(jì),達(dá)到合適研磨比研磨能量,提高物料研磨效率,使物料研磨細(xì)度達(dá)到納米級(jí),經(jīng)第三方馬爾文激光粒度測(cè)試儀測(cè)定,細(xì)度可達(dá)≤50nm。
