Clinic ultrafine grinder

Jinan Dawei Machinery Co., Ltd. combines ultrafine powder technology with traditional Chinese medicine and has conducted research on the characteristics and particle size properties of over 2000 types of Chinese medicinal materials. After tens of thousands of ultrafine grinding and cell wall breaking (membrane) experiments, the concept of "Chinese medicine cell level ultrafine grinding, full component drug delivery, micronized Chinese medicine, and Chinese medicine cell wall breaking decoction pieces" has been proposed both domestically and internationally. We have accumulated a wealth of successful practical experience in achieving traditional Chinese medicine cell level ultrafine grinding operations with the main goal of cell wall breaking.

This device belongs to the fourth generation vibration mill, which has high crushing efficiency, high wall breaking rate, low crushing temperature (temperature controllable), and high efficiencyCrushing, no residue left, fully enclosed operation, materialsnoneCharacteristics such as wear and tear. The particle size of the powder can reach 1-0.1 μ m, and the cell wall (membrane) breaking rate is over 98%. Nowadays, Dawei ultrafine grinding and cell wall breaking technology have been widely used in industries related to powder applications, such as medicine (including veterinary drugs and pesticides), food (food), cosmetics, chemical building materials, metallurgical energy, electronic environmental protection, and resources, and have gained a large number of users' recognitionrecognizeandGood reputation.

working principle

DaweiClinic ultrafine grinderIt belongs to the new fourth generation vibration mill, which adopts multiple advanced technologies and applies high-speed impact force and shear force according to the different characteristics of the material, so that the material is subjected to high acceleration impact, friction, compression, cutting and other effects of the medium in the grinding cylinder, and can achieve ideal powder crushing effect in a short time. The material becomes fluidized during the crushing process, so that each particle has the same stress state, achieving precise mixing (dispersion) effect while crushing. By adjusting parameters such as acceleration, it is possible to achieve operations with the goal of crushing and grinding or precision mixing (blending) as the main objective.

Clinic ultrafine grinderThe working principle of vibration crushing is adopted, and grinding media such as hard material balls, rods or columns are filled in the grinding cylinder (crushing chamber). Under the action of external excitation force, the grinding cylinder produces circular vibration in the clockwise and counterclockwise directions as shown in Figure 1. The strong vibration of the grinding cylinder causes the medium inside the grinding cylinder to undergo a throwing motion. Under the action of this throwing motion, each medium produces a rotation in the same direction as the circular vibration. At the same time, the medium group also produces 3-5 low-frequency rotations opposite to the circular vibration. So the medium sometimes disperses and sometimes collides with each other, producing a positive impact force p and a lateral shear force L on the material as shown in Figure 2. The material is finely ground, broken, and crushed under the impact, compression, and shear forces of P and L.

The Dawei ultrafine grinding series equipment has the following characteristics

1. The parts in contact with the material are all polished stainless steel, which is a universal material for medical and food machinery (can also be changed to other metal materials according to user requirements), to avoid the mixing of heavy metals such as arsenic, cadmium, mercury, lead, copper, etc.

2. Cleanliness and hygiene: Smooth inner and outer surfaces, versatile use of one machine, reduced pollution, and reduced cleaning workload; The crushing process is fully enclosed without dust spillage, fully improving the working environment, and effective ingredients are not lost.

3. Adopting a composite (transparent) soundproof cover greatly reduces noise.

4. Easy to disassemble (assemble), easy to clean, and easy to change materials. Can be cleaned and disinfected with water, compressed air, alcohol, steam, etc.

5. Easy to operate: Capacity adaptation, ensuring material discharge, easy operation and material replacement.

6. Easy maintenance: compact structure, small footprint, and convenient maintenance.

7. Improving the environment: Fully enclosed operations with dust spillage, no loss of active ingredients, and no generation of drug residues can improve the working environment.

8. Efficiency: Crushing, no residue left. The bidirectional effect of high-speed impact force and shear force shortens the crushing time and improves the crushing efficiency.

9. Broad spectrum adaptation: Suitable for any fibrous, high toughness, high hardness, or moisture content material. Materials that require breaking of cell walls, such as pollen and other spore materials, have a breaking rate of over 98%. Adapt to both dry and wet crushing simultaneously. Water, alcohol, or other liquids can be added during wet crushing.

10. Temperature controllable: Through configuration, micro crushing can be carried out at high temperature, room temperature, and low temperature, which can maintain the original physicochemical properties and active ingredients of the material. Inject cold water into the jacket on the outer wall of the grinding cylinder. The crushing temperature can be controlled by adjusting the temperature and flow rate of the cooling water. Low temperature crushing, the freezing system can reach a low temperature of minus 35 ℃ (low-temperature configuration).
