求翻译：实验前物料总质量 ，粉碎再生后物料总质量 。经过多级筛分后的粒度质量分布：大于200目（250 ）范围内的物料质量分别为是什么意思？

Before the experiment materials the total mass of crushed recycled material total mass. Multi-level screening of the particle size mass distribution: greater than 200 mesh (<75), 160 to 200 mesh (75 96) 120 ~ 160 mesh (96 120), 80 to 120 mesh (120 to 180) 60 to 80 mesh (180 to 250), less than 60
