对偏磷酸铝进行球磨的方法
摘要：
制备偏磷酸铝(ALMP)微粒产品的方法包括：球磨机的研磨室装料研磨介质，以及将ALMP进料装载到研磨室中。以0.25-0.5的颗粒降低指数，用研磨介质将ALMP进料研磨成ALMP颗粒。在进行研磨时间段期间的多个时间阶段，从研磨室去除ALMP颗粒的细部分，同时使得ALMP颗粒的粗部分仍然留在研磨室内进行额外研磨。从由研磨室取出的ALMP颗粒制备具有中值粒度为100-700μm的粒度分布的ALMP微粒产品。
摘要（英）：

A method of preparing an aluminum metaphosphate (ALMP) particulate product includes charging a milling chamber of a ball mill with grinding media and loading an ALMP feedstock into the milling chamber. The ALMP feedstock is milled with the grinding media into ALMP particles at a particle reduction index in a range from 0.25 to 0.5. At a plurality of time steps during a period in which the milling is carried out, a fine fraction of the ALMP particles is removed from the milling chamber while a coarse fraction of the ALMP particles remains in the milling chamber for additional milling. An ALMP particulate product with a particle size distribution having a median particle size in a range from 100 [mu]m to 700 [mu]m is prepared from the ALMP particles removed from the milling chamber.
