　　What are the highlights of Dawei Machinery's ultrafine pulverizer?

In recent years, with the rapid development of industries such as pharmaceuticals, chemicals, and food, the market demand for ultrafine grinding equipment has been continuously expanding. However, at the same time, industry competition is also intensifying. So, what are the characteristics and advantages of Dawei Machinery's ultrafine pulverizer that make it stand out?

It is reported that the Dawei Mechanical Ultra fine Grinding Equipment belongs to the new fourth generation vibration mill. Based on the different characteristics of the material, it adopts multiple technologies such as fully enclosed non grading technology, compressed micro grinding technology, dynamic optimization technology, and mechatronics integration technology. It also uses high-speed impact force and shear force to subject the material to high acceleration impact, friction, compression, cutting and other effects in the grinding cylinder, which 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 operations with the goal of crushing and grinding or precision mixing (blending) as the main objective.

The device adopts the working principle of vibration crushing, in which a grinding medium (such as hard material balls, rods or columns) is filled in the grinding cylinder (crushing chamber), and the grinding cylinder produces circular vibration under the action of external excitation force; The strong vibration of the grinding cylinder causes the medium inside the grinding cylinder to undergo 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 produces 3-5 cycles of low-frequency rotation opposite to the circular vibration; The medium disperses and collides with each other at times, generating positive impact force and lateral shear force on the material; The material is finely ground, broken and crushed under the action of impact, compression and shear.

In terms of features, this equipment has the characteristics of material safety, cleanliness and hygiene, low noise, easy disassembly (assembly), easy cleaning, easy material replacement, easy operation, convenient maintenance, high crushing efficiency, strong broad-spectrum adaptability, temperature control (room temperature, low temperature, ultra-low temperature), fully enclosed operation, no dust or loss, thorough crushing, and no residue residue left.

Compared with traditional crushers, vibrating ultrafine crushers have five major advantages. Firstly, through cell level micro pulverization, the active ingredients are fully released, resulting in high bioavailability; Under the premise of ensuring, the dosage can be reduced; The quality of the finished product is stable and controllable. Secondly, through cell level micro pulverization, combined with application technologies such as surface modification, particle design, composite or precision coating, effective means have been provided for the development of traditional Chinese medicine dosage form reform towards miniaturization and diversification. Thirdly, through cell level micro pulverization, drug efficacy can be improved (reducing dosage), production processes can be simplified (reducing labor and equipment investment), and production costs can be reduced. Fourthly, due to the stable and controllable quality of the finished product, which is clearly precise, compact and high-end, with a large profit margin and market competitiveness, sales will increase. Fifthly, by improving the quality of finished products, reducing costs, and increasing sales, the finished products have market competitiveness and high added value, effectively reducing investment risks in technology, processes, and equipment, and greatly shortening the investment payback period.

　　Further support innovation in traditional Chinese medicine pharmaceutical technology

In recent years, with the intensification of population aging and the support of a series of favorable policies, the traditional Chinese medicine industry is accelerating its development and growth, and the field of traditional Chinese medicine grinding has also received great attention.

The ultrafine grinding of traditional Chinese medicine currently mainly refers to cell level micro grinding. The main active ingredients of animal and plant medicines are usually distributed within cells and intercellular matrix, with intracellular dominance. When the cell breaks through the wall, the active ingredients inside the cell are exposed, so the efficacy is greatly improved and the onset speed is fast.

At present, there are technologies and equipment such as ball mills, planetary mills, rotor crushers, airflow crushers, and vibration crushers in China, but they all have certain defects. The high-quality development of the traditional Chinese medicine crushing industry urgently requires innovative crushing equipment and processes.

The process application centered on micro mechanical cell level micro grinding technology provides a broad operational space for innovation in traditional Chinese medicine pharmaceutical technology. On the one hand, this device solves various problems in traditional Chinese medicine crushing operations, including strong fibrous properties (such as Ganoderma lucidum, licorice, etc.), high sugar and high viscosity (such as wolfberry, Ophiopogon japonicus, etc.), and can adapt to various traditional Chinese medicines; On the other hand, it is also beneficial for the reform of traditional Chinese medicine dosage forms, the reduction of drug dosage, and the improvement of micro powder technology level.

In addition to being applied in the traditional Chinese medicine industry, Dawei ultrafine grinding equipment is also widely used in various industries related to powder application, such as biopharmaceuticals, food, cosmetics, building materials (preparation of water slag, fly ash, etc.), chemical industry, metallurgy, environmental protection (brick making from garbage micro powder, etc.), electronics (slurry, graphite emulsion, etc.), etc.

According to the data, Da Micro Machinery is a high-tech enterprise specializing in micro (nano) Rice noodles technology, process, equipment R&D and manufacturing and related technical services.

Since its establishment, the company has been committed to the research and development, design, updating and improvement of ultrafine grinding equipment and cell wall breaking equipment.
