棕刚玉球磨整形砂是通过球磨机生产线加工处理而成，堆积密度比巴马克砂低，棕刚玉球磨整形砂的特点是纯度高，自锐性强，
韧性好，磁性物含且特低，用其制成的磨具磨削锋利，发热率低，磨削比高，且使用时沾附少;制成的烧结磨具具有烧成后颜色深
蓝、不起网状裂纹、无锈斑的特点，水洗后.粉尘特低。适用于制造陶瓷、树脂高固结磨具以及研磨、抛光等。
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币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.
