基于PREP技术可以制备出高纯净度粉末，PREP技术每根电极棒重量9.8kg，全部雾化完毕需要5分钟，去掉设备抽真空以及换电极棒的时间，一台设备每天实际可雾化10根电极棒，按粉末收得率90%计算，一台设备每天可制粉88kg，按现场3台设备、每年300天的工作时间测算，其实际制粉能力达到79吨/年。专家组通过对现场单位时间实际制粉量并结合设备数量进行综合测算，一致认为其粉体的年制备能力为79吨/年，达到并超过了50吨/年的课题预期目标。

Based on PREP technology, high-purity powder can be prepared. The weight of each electrode rod in PREP technology is 9.8kg, and it takes 5 minutes to complete the atomization. The time for removing the equipment vacuum and changing the electrode rod is removed. One equipment can actually atomize 10 electrode rods per day. According to the 90% powder recovery rate, one equipment can produce 88kg powder per day. According to the working time of three equipment on site and 300 days per year, its actual pulverizing capacity reaches 79 tons/year. Through the comprehensive calculation of the actual powder production per unit time on site and the number of equipment, the expert group agreed that the annual powder production capacity was 79 tons/year, which reached and exceeded the expected goal of 50 tons/year.
