棕剛玉對輥砂是通過對輥機生產(chǎn)線加工處理而成，堆積密度比球磨整形砂低，但純度高，自銳性強，韌性好，磁性物含量特低，用
其制成的磨具磨削鋒利，發(fā)熱率低，磨削比高，且使用時沾附少;制成的燒結(jié)磨具具有燒成后顏色深藍、不起網(wǎng)狀裂紋、無銹斑的
特點，適用于制造陶瓷、樹脂高固結(jié)磨具以及研磨、拋光等。
BFA with low Bulk Density (can be washed as your requirement)
The abrasive grains of this products crashed by rolling machine.
The bulk density is lower than the ball mill 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 by sharp 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 low bulk density is applicable to make ceramic and resinoid high bonded abrasive
tools, grinding abrasive and polishing materials.
