(4)粗粉碎：开启振磨机，开启送料器将预烧好的颗粒送入振磨机，送料速度控制在10-12kg/min；
(5)二次配料细磨：将粗粉碎后的粉料送入砂磨机中加入纯水，料水比为1：0.62，加入氧化铜和氧化钙，砂磨时间60-90min，粉料转变为料浆状态粉体粒径控制在1.0-1.25μm；将细磨后料浆注入料浆池，然后分别加入PVA胶水、分散剂、消泡剂，搅拌10-15min后备用；
(6)喷雾造粒：开启压力泵将二次配料细磨后的料浆以1.9-2.0mPa的压力沿喷枪管道进入旋流室，在旋流室内，料浆在涡旋片内高速旋转，形成近似自由涡流，通过喷枪喷嘴喷出料浆，在干燥塔内雾化，料浆遇到热空气，大部分水分蒸发，转变为颗粒；
(7)三次配料、检测包装：将喷雾造粒后的颗粒料加入硬脂酸锌，送入混料机混合3-5min，检测包装。
作为优选，所述粗粉碎后粉粒的粒径控制在1.0-2.5μm。
作为优选，所述二次配料细磨中的料浆池内溶质质重设定为4500kg，然后分别加入10％PVA胶水450kg、分散剂1500ml、消泡剂1000ml。
