Common misunderstandings in the use of small laboratory shredders

As a basic laboratory equipment necessary for laboratory---the use frequency of small laboratory pulverizer is relatively high, the more used, the more problems caused by the corresponding use process will be more, various operating procedures, fault handling, attention Matters, maintenance and overhaul need to be taken seriously. In fact, the range of laboratory pulverizers is relatively large, and small ultra-fine pulverizers, high-speed universal pulverizers, airflow superfine pulverizers, etc. are all in the category of laboratory pulverizers, and they have a common feature that can satisfy the experiment. For the crusher's fineness and volume, as well as some specific functions, today we will take a few typical equipment to explain the common misunderstandings and avoidance methods used in laboratory grinders!

* We first say that the small high-speed pulverizer commonly used in the laboratory Zui, also known as the small steel mill is also called the high-speed universal pulverizer, Benchen BF-10 is a typical representative of this type of pulverizer, this smasher Zui big The characteristic is that the application range is wide, the pulverization process is closed without dust, and the fineness can be controlled by the pulverization time. Although an older model is a wide range of applications, many customers will encounter many problems in the process of using them. For example, the common one is that the fuse is blown, which causes several reasons for this failure: The amount of feed is too large, causing the machine to be overloaded. 2. The material volume is too large or irregular to cause the card cutter. 3. The voltage is unstable or the single pulverization time is too long. Speaking of the smashing time, we have to say a few words here. The small high-speed pulverizer BF series and Taiwan rong's RT series use ultra-high-speed motors, which can reach 25,000 rpm, so high speed can guarantee the pole. The pulverization of the material is achieved in a short period of time. Although the single pulverization time given in the specification is 1-3 minutes, the actual single pulverization for 3 minutes is extremely rare. When pulverizing brittle materials, we generally recommend the pulverization time in 1 minute. Within the time of pulverizing fibrous materials such as traditional Chinese medicine, the pulverization time is less than 2 minutes. When pulverizing low heat sensitivity or ore materials, we can smash for 3 minutes in order to pursue fineness. If the result of smashing still needs to be improved, we can Through multiple smashing to achieve the goal, remember to blindly smash for a long time in the selection of smashing time, which is actually a kind of damage to the machine itself.

The second laboratory pulverizer we are talking about is the current mainstream model - the small laboratory superfine pulverizer. At present, the small superfine pulverizer is mainly the FDV of Taiwan Youshao (Yosaki) brand, the desktop superfine pulverizer RT-UF26 of Taiwan Rongcong Company and the airflow type ultrafine pulverizer RT-25 of Taiwan Xinzhen Company. As the original Taiwanese products, these three machines have been very good in quality and reputation after more than ten years of testing. Whether it is the crushing of western medicine raw materials or the crushing of traditional Chinese medicine, the advantage of crushing fineness is still very much compared with domestically produced machines. Obviously, all three machines adopt the principle of air-selective discharge and high-speed impact shearing, and the discharge mode is continuous. Therefore, a very important operation in the pulverization process is to keep the feed speed stable, and the feeding speed is not only high. Intuitively reflected in the change of motor current, it has a relatively large impact on the product's discharge fineness and output. Here, the problem that Zui is prone to is that the feeding speed is not well controlled, and even many customers do not read the manual carefully, resulting in When feeding, the whole batch of materials is directly put into the machine, causing the instantaneous current of the machine to increase, the fuse is burnt and even the motor is burned, and the material is charged. The slowly reflected current can be observed through the ammeter. If the speed is not good, the current is always running at the specified upper limit, and the motor is always in an overload state. Then the big accident of burning the motor will easily occur, so the above several devices are in use. Must pay attention to the control of the feeding speed.

As a small equipment---the laboratory pulverizer is precise and efficient, so it can't be used in the process. The above are just two common misunderstandings of our example: the pulverization time is too long and the feeding speed is unstable. We hereby remind all users to read the relevant contents of the manual before use, to be familiar with the operation process, to keep in mind the operating specifications, and to understand the principle of failure. Only in this way can we achieve the purpose of crushing quickly and efficiently in our future use, and Extend the service life of the equipment to protect the safety of the users. The engineering staff of this time will continue to improve the contents of the manual according to your feedback, and concentrate on the services of the users. I also hope to further communicate with you!
