几年前,我们在粮食机械厂购买了一套MF-25型磨粉机的机架、方筛和传动部分部件,经过改装组成了药粉筛,用于蜜丸药粉筛选,用费九百元。长期使用以来没出现任何毛病,效果很好。这种筛的投料口、方筛、出料口都有封闭装置从而大大减少了药粉飞扬,改善了生产环境,提高了出粉率。此筛振幅小、频率高,一般药粉筛选量为100～120kg/h。整机占地面积不足1m~2,结构紧 A few years ago, we purchased a frame, square screen, and transmission parts of an MF-25 mill at the Grain Machinery Plant. After being modified to form a powder sieve, it was used for the screening of honey pill powder, which cost RMB 900. . No problems have occurred since long-term use, and the effect is very good. The feeding port, square sieve and discharge port of this sieve have closed devices, which greatly reduces the flying of the powder, improves the production environment, and improves the extraction rate. The screen has small amplitude and high frequency, and the general powder screening amount is 100-120kg/h. The whole machine covers an area of ​​less than 1m~2 and the structure is tight
