Ultrasonic vibration screen or air flow screen for pharmaceutical fillers?

The function of pharmaceutical fillers can increase the weight or volume of tablets, and can also be used as flavoring agent, which is conducive to molding and dosage division Commonly used fillers include starch, sugar, cellulose and inorganic salts, which are in the form of granules or powders There are many fillers in the form of powders, which can be directly pressed into tablets Pharmaceutical grade excipients should meet the pharmacopoeia standard of 2015 version They can be used only when there are relevant standards for particle size and solubility Is ultrasonic vibrating screen or air flow screen used for pharmaceutical filler? Only when the mesh number of pharmaceutical filler is more than 300 and reaches a certain fineness, can it be integrated into the drug In order to facilitate the accurate mesh number, pharmaceutical filling extrusion manufacturers will choose vibrating screen It is realized in the sub machine Because the mesh number is smaller, some are lighter Some users ask if they can use Jinhe mechanical ultrasonic vibration screen and air flow screen These two types have rich screening experience for fine powder above 300 mesh What's the difference between these two types? Introduction to medical ultrasonic vibration screen: ultrasonic vibration screen As an upgrade on the three-dimensional rotary vibrating screen, a set of ultrasonic system is added, which can effectively screen all kinds of screening problems, such as strong adsorption, easy agglomeration, high static electricity, high precision, high density, light specific gravity, etc., so that the screening of ultrafine powder is no longer difficult, especially suitable for users of high-quality and fine powder The screening mesh number can reach 300-800 mesh In order to meet GMP standards, the pharmaceutical industry Yes, the equipment will be made of 304 or 316 all stainless steel Introduction to medical air flow screen: air flow screen It is a good continuous screening of powder materials with fineness range of 80-500 mesh for light powder As an accurate screening equipment based on aerodynamics theory, Jinhe mechanical air flow screen abandons the traditional principle of gravity potential energy operation and opens up a new way of screening work with kinetic energy of fluid It uses high-speed air flow as carrier in closed state, The fully diffused powder particles are ejected into the screen with enough kinetic energy to achieve the purpose of rapid classification According to the above two introductions, the screening accuracy of ultrasonic vibrating screen is higher than that of air flow screen, and the working principles of the two types are quite different Pharmaceutical fillers are not so light It is better to choose ultrasonic vibrating screen for pharmaceutical fillers Zui
