Firstly, the mechanism of the preparation of superfine quartz powder with ball mill is studied in this article, based on nature of quartz material, Griffiths strength theory and the crush theory of planetary ball mill. The problem of granulation during the process of the preparation of superfine quartz powder is studied minutely. And proposed increasing dispersant and disperser medium to restrain granulation, and dispersing use ultrasonic after milled.

首先，本文结合石英材料的基本物性，以格里菲斯强度理论和行星式球磨机的粉碎原理为基础，研究了球磨法制备超细石英粉体的机理，同时对粉石英制备过程中的团聚问题及其控制作了细致的研究，提出粉磨过程中增加分散剂和分散介质来抑制团聚，粉磨后采用超声法进行分散，并确定了最佳分散剂、分散介质的用量和最佳超声分散时间。

By seeing about, we chose the vertical technology and determined the quality indexes and process parameters after comparing the grinding efficiency, energy consumption and final cost of vibromill, ball mill, rolling press and vertical mill.

经考察了解，并分析振动磨、球磨机、辊压机及立磨系统工艺粉磨效率、能耗、成本等优缺点的基础上，选用了立磨系统工艺，确定了质量控制指标及生产工艺参数，投产后生产线生产运行状况良好，S95级矿渣粉产品质量稳定，实现了当年投产当年达效的目标。

The biomechanical tests showed that two kinds of artificial bones had not significant difference on compressive strength and Young\'s modulus(P＞0.05),while the flexural strength of nano-nacre artificial bone was less than the control group(P＜0.05).3.The results of CCK-8 showed that the difference were not significant in each group,the proliferation of osteoblast reached the peak at the 5th day;7 days after being co-cultured,the total protein content of study group was higher than control group and blank group(P＜0.05),while the difference between control group and blank group was not significantP＞0.05The difference of alkaline phosphatase activities among three groups was not significant(P＞0.05The SEM view showed that osteoblast attached and grew well in two kinds of artificial bone.4.X-ray photography showed that two kinds of powder started to degrade in 2 weeks;this phenomenon became more appear in 4 weeks,nano-nacre powder degraded faster than micron-nacre powder,while the hole shadow was easy to be found;in 8 weeks,all the femoral holes recovered and returned to normal bone mineral density in all groups.Analysis of tetracycline fluorescent double marks in the hard tissue grinding slices indicated that new bone grew fastest around the bone defect area in study group,while most slowly in blank groupP＜0.05 SEM(scanning electron microscope observation showed that nano-nacre powder degraded more quickly.The same result can be found through the demineralized sections morphometric analysis,and both of the composite artificial bones made from those two kinds of nacre powder had the good connection with the adjacent tissue in rats body without apparent inflammatory response.5.X-ray photography showed that rabbit\'s bone defects healed faster in study group since NNAB implanted than in control group since MNAB implanted.At 24 weeks after operation,bone density in radial defects had nearly accessed to the normal area,while lower in control group,and turned up nonunion in blank group;The checking of BMD showed that results in study group were higher than those in control group at 8,16 and 24 week(P＜0.05), and the difference between the BMD values in study group at 24 week and those in blank group was not significant(P＞0.05).The gross specimens showed satisfactory histocompatibility both in study group and in control group,with bone tissue growing from two sides into the center of implanted materials; Normal slices in HE stain and hard tissue grinding slices in Stevenel\'s blue/Van Geison\'s picro-fuchsin stain showed that the bone growth tendency was better in study group than that in control group,and the medullary cavity had been penetrated to the implanted materials in study group at 24 week;Analysis of tetracycline fluorescent double marks in the hard tissue grinding slices indicated that new bone in both groups grew fastest 8 weeks after surgery,while slow down at 16 week.
