在使用超微粉碎机粉碎前应该准备哪些工作?

首先应明白粉碎目的,理解粉碎机原理,依据被粉碎物料的特性选择好粉碎机,如锤击式粉碎机,其原理是物料借撞击及锤击作用而粉碎,粉碎后的粉末较细;另一种是万能粉碎机,其原理是物料以撞击伴撕裂研磨而粉碎,改换不向规格的筛板网。能得到粗细不同的粉末,且相对平均,适用于粉碎强黏性的浸膏、结晶性物料等,如蜂蜡、阿胶、冰片。然后依据应用目的和欲制备的药物剂型控制恰当的粉碎度。
First of all, we should understand the purpose of comminution, understand the principle of comminuter, and choose a good comminuter according to the characteristics of the crushed material, such as hammer mill, whose principle is that the material is crushed by impact and hammering, and the powder after comminution is finer; the other is universal comminuter, whose principle is that the material is crushed by impact and tear grinding, and the sieve mesh of non-directional specifications is changed. It is suitable for crushing highly viscous extracts, crystalline materials, such as beeswax, donkey-hide gum and borneol. Then the appropriate grinding degree is controlled according to the purpose of application and the dosage form to be prepared.
为了进步粉碎效率。维护粉碎机械,降低能耗。在粉碎操作前成留意对粉碎物料停止前处置:如按有关规则,停止净选加工;药材必需先经枯燥至—定水平,控制水分等。并应在粉碎机的进剧口设置磁石,吸附参加药料中的铁屑和铁丝,严防金属物混入机内。以免发作事故,粉碎机启动必需无负荷,待机器全面启动、并正常运转后。再进药。停机时,应待机内物料全部出后,约2—3分钟,再断电源。

In order to improve the crushing efficiency. Maintain crushing machinery and reduce energy consumption. Before crushing operation, pay attention to the disposal of crushed materials before stopping: if according to the relevant rules, stop net processing; medicinal materials must first be dry to a certain level, control moisture, etc. Magnets should be installed at the entrance of the crusher to absorb the iron scraps and wires in the powder, so as to prevent metal from mixing into the crusher. In order to avoid accidents, the mill must start without load until the machine is fully started and running normally. Take the medicine again. When the machine stops, all the materials in the standby machine should be discharged for about 2 - 3 minutes before the power supply is cut off.
粉碎前和粉碎过程中,应留意及时过筛,以免局部药物过度粉碎。并可进步工效;在粉碎过程中应留意减少细粉飞扬,并避免异物掺入。特别在粉碎毒药或刺激性强的药物时,应留意防护,做到操作平安;植物药材必需全部粉碎应用,较难粉碎局部(叶脉、纤维等)不应随意丢掉,以免损失药物的有效成分,使药物的含量相对减少或增高。
Before comminution and in the process of comminution, we should pay attention to timely screening in order to avoid excessive comminution of local drugs. It can also improve work efficiency; in the crushing process, attention should be paid to reducing the flying of fine powder and avoiding foreign body incorporation. Especially when crushing poisons or irritating drugs, we should pay attention to protection and safe operation; plant medicines must be crushed and applied completely, and parts (veins, fibers, etc.) which are more difficult to crush should not be thrown away at will, so as to avoid the loss of effective ingredients of drugs, so that the content of drugs is relatively reduced or increased.
