目前世界选矿业对球磨操作研究最多的是衬板材质和形状,介质材质和形状。介质材质和形状直接涉及到磨矿效率、金属回收率及金属材料的消耗,因此,引起了人们足够的重视。迄今为止,从磨矿介质形状上看,国内外普遍应用的仍然是磨球与磨棒,崭露头角的有圆柱和圆台。我们设计了一类新型磨矿介质(包括两种),这类新型介质从外形上看,它们是两端呈球面,中间为柱形(或梯形)的棒球体(分别称为A、B型棒球)见图1所示。
At present, the world’s mineral processing industry on the ball mill operation is the most liner material and shape, medium material and shape. Medium material and shape directly related to grinding efficiency, metal recovery and consumption of metal materials, therefore, attracted enough attention. So far, from the point of view of the shape of the grinding media, there are still commonly used grinding balls and grinding rods at home and abroad, with columns and round tables emerging. We have designed a new class of grinding media (both included) that are spherical in shape at the ends and cylindrical (or trapezoidal) baseballs in the middle (called Type A, B Baseball) See Figure 1 below.
