棕剛玉球磨整形砂是通過球磨機生產線加工處理而成，堆積密度比巴馬克砂低，棕剛玉球磨整形砂的特點是純度高，自銳性強，
韌性好，磁性物含且特低，用其制成的磨具磨削鋒利，發熱率低，磨削比高，且使用時沾附少;制成的燒結磨具具有燒成后顏色深
藍、不起網狀裂紋、無銹斑的特點，水洗后.粉塵特低。適用于制造陶瓷、樹脂高固結磨具以及研磨、拋光等。
BFA with medium bulk density(can be washed as your requirement)
The abrasive grains of this kind of product is crashed切ball mill machine. The bulk density is lower than the Baramc grains.
It is characterized by its high purity， strong self-sharpening, good toughness, ultra-low content of the magnetic materials. It can be made into grinding
tools that is characterized切sha幣grinding, low heat generation ratio, high grinding rate and few coating in the using course, and the sintering grinding
tools that is characterized by deep blue color after firing, without resillage, without rust and so on. After water washing, with very low dust.Brown Fused
Alumina with medium bulk density is applicable to make ceramic and resinoid high bonded abrasive tools, grinding abrasive and polishing materials.
