Types of Pharmaceutical Vibro Sifter

The use of vibrating screen is generally inseparable from the production process of medicines, and the pharmaceutical vibro sifter is a special type of vibrating screen. Pharmaceutical vibro sifter is a vibrating screening equipment specially designed for the pharmaceutical production industry. It must meet the safety standards for pharmaceutical equipment in the "Pharmaceutical Production Quality Standards", and strictly ensure that the pharmaceutical production process will not be polluted.

There are the following types of medical vibrating screens:

The pharmaceutical vibro sifter can be divided into four types: pharmaceutical rotary vibrating screen, medical linear vibrating screen, medical ultrasonic vibrating screen, and pharmacopoeia sifter.

1. Circular pharmaceutical vibro sifter

The working principle is to use a vertical vibrating motor installed in the bottom cylinder to drive the sifter. The unbalanced weight of the vibrating motor generates three horizontal, vertical, and inclined steps. Yuan movement, so as to drive the material to achieve high-precision material screening and classification. The circular medical vibrating screen is the most widely used type of vibrating screen in the pharmaceutical production industry. Chinese medicinal liquid, medicinal powder, and granular medicine can be screened, but it can only meet the screening requirements within 400 mesh.

2. Pharmaceutical ultrasonic vibro sifter

 also called ultrasonic medical vibrating sieve, is a commonly used screening equipment when processing fine medicinal powder with more than 400 mesh. The medical ultrasonic vibrating screen is an extension of the rotary vibrating screen. It is designed and produced to solve the problem of easy blocking of high-precision powder materials during the screening process. When the material is put on the screen surface, while being subjected to the three-dimensional motion generated by the motor, the screen is simultaneously subjected to the high-frequency and low-amplitude ultrasonic vibration wave of the ultrasonic screening system, so that the material is suspended on the screen surface at low altitude, thereby solving the screening process Screening problems such as blocking nets, sticking nets, adsorption, theater troupes, static electricity, light specific gravity and so on.

3. Pharmaceutical linear vibrating screen

It is a commonly used pharmaceutical vibro sifter type for granules, tablets, pills and other drugs. It has the outstanding advantage of large screening output. It is a Dahan vibro sifter manufacturer for medicine. The special vibrating screening equipment tailored to the industry meets the requirements of pharmaceutical equipment. The production process will not cause pollution to medicines. It is the standard choice for material screening and classification in the pharmaceutical industry.

4. Pharmacopoeia sieve

It is also known as particle size inspection sieve, the biggest difference from the above 3 types is that the equipment is not used for production in pharmaceutical factories, but is mainly used for pharmaceutical research institutes, scientific research units, etc. to determine the particle size of drugs. Used for quality inspection, particle size analysis, etc. According to national standards, the pharmacopoeia sieve consists of 9 pharmacopoeia sieves with different meshes, one non-porous sieve and one sieve cover. The screen frame is made of SUS304 (0Cr18ni9) stainless steel stretched and polished, with a wall thickness of 0.6-0.7 mm. The surface is light and visible. The overall shape is sturdy and durable. There is no magnetism. The screen and the screen frame are fixed by soldering and will not slack. Can withstand high temperatures below 300 degrees. The mesh meets the GB6003.1-1997 standard, and is used after inspection by tool microscope, projector and other equipment, which can ensure the consistency and interchangeability of the same type of pharmacopoeia sieve produced at any time.
