Huangjing ultrafine grinder

working principle

Da Micro Mechanical Ultra fine Grinding Equipment belongs to the new fourth generation vibration mill. It adopts fully enclosed pure physical grinding technology 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 grinding 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 grinding and precision mixing (blending) as the main purposeHuangjing ultrafine grinderThe homework for the target.

The device adopts the working principle of vibration crushing, filling the grinding medium such as hard material balls, rods or columns in the grinding cylinder (crushing chamber). The grinding cylinder produces circular vibration in the clockwise and counterclockwise directions as shown in Figure 1 under the action of external excitation force. 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 crusher adopts the following technologies

1. Fully enclosed non graded technology: The fully enclosed multi grinding non screening technology used to preserve the active ingredients effectively avoids phenomena such as segregation and loss of active ingredients, and environmental pollution caused by dust spillage.

2. Compression micro crushing technology: In order to improve the crushing efficiency and effectiveness, high-speed impact force and shear force are used to subject the material to the squeezing, kneading, and tearing effects of the medium in the grinding cylinder, shorten the crushing time, and improve the crushing efficiency; At the same time, due to the fluidized state of the material and the same stress state of each particle, its own viscous effect can form uniformly dispersed and precisely composite particle clusters in the finished product, increase density and improve bioavailability, and enhance micro crushing efficiency and technology.

3. Dynamic optimization technology: a technology that optimizes and adapts according to the different characteristics of materials while ensuring the improvement of micro crushing efficiency and effectiveness.

4. Mechatronics technology: a technology that achieves high performance and level of equipment, reduces manual labor, ensures stable and controllable product quality, and avoids quality instability and pollution caused by excessive manual intervention.

5. Comprehensive automation technology: equipped with single machine multifunctional automation (FMC flexibility), making small-scale drug production as simple as large-scale assembly line production.

6. Purification technology: The Dawei ultrafine grinder series is designed and manufactured strictly in accordance with GMP standards, which can meet the special requirements of pharmaceutical powder equipment.

The Dawei ultrafine grinding series equipment has the following characteristics

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).
