High Speed Mechanical Impact Pulverizer
The high-speed mechanical impact pulverizer is a piece of ultra-fine grinding equipment that utilizes a high-speed rotating rotor and impact elements to pulverize materials through impact, collision, and shearing. It is primarily used in industries such as chemicals, minerals, metallurgy, construction materials, food processing, and pharmaceuticals. It is suitable for pulverizing non-sticky materials of medium hardness—specifically those with a Mohs hardness of less than 5 and a moisture content below 10%.
Impact Pulverizer Working Principle
- Feeding: Material is drawn into the main unit’s grinding chamber by a vacuum feeding system.
- Grinding: High-speed rotating hammers strike the material within the chamber; simultaneously, particles undergo mutual impact, friction, shearing, and compression, ultimately achieving ultrafine autogenous grinding.
- Classification: Ground material is carried by the rising airflow into the upper turbine classifier, where centrifugal force, gravity, and negative pressure separate coarse particles from fine ones.
- Fine Powder Discharge: Fine powder meeting specifications passes through the impeller’s airflow field and is conveyed to downstream equipment for further precision classification or collection.
- Coarse Powder Recirculation: Coarse particles that do not meet specifications are flung against the chamber wall and fall back into the grinding zone for regrinding.
Exhaust Treatment: Exhaust gas containing trace amounts of dust is filtered and purified by a dust collection system before being discharged by an induced draft fan, ensuring a clean, pollution-free output.
Our Advantages
Under the same power, the efficiency is increased by 40%, and the energy consumption is reduced by 70%.
The grinding roller and liner are made of wear-resistant materials and have a long service life.
The PLC automatic control method is adopted to accurately control the grinding pressure.
The fineness of the final products can be adjusted arbitrarily between 325 mesh and 2500 mesh.
Equipped with a double limit device to protect the equipment from impact and vibration.
The roller sleeve and liner are specially designed, which is easier to form a material layer than ordinary vertical mills.
High Grinding Precision, Controllable Particle Size
Leveraging an optimized jet structure and classification flow field design, the high-speed mechanical impact pulverizer achieves enhanced efficiency in both grinding and classification. The finished product features a concentrated, narrow particle size distribution free from large-particle impurities. Particle size is freely adjustable within the 3μm–74μm range, ensuring stable and reliable grinding precision.
Smart and Cost-Efficient
The impact pulverizer integrates the pulverizing and classifying processes into a single unit. This simplifies the production workflow while reducing equipment investment and O&M costs. Equipped with a PLC-based automated control system, it offers simple, convenient operation and fully automated processing, significantly boosting production efficiency.
Capable of Processing Flammable and Explosive Materials
The high-speed mechanical impact pulverizer supports an inert-gas closed-loop grinding process, enabling the processing of flammable, explosive, and easily oxidizable materials. It is suitable for precision production operations involving specialized, high-risk materials.
Applications of Impact Pulverizer
1. Ultrafine processing of Chinese herbal medicine powders: various rhizomes and roots such as Notoginseng (Sanqi), Gastrodia (Tianma), Hawthorn, Astragalus, Danshen (Salvia miltiorrhiza), and Poria.
2. Ultrafine processing of non-metallic minerals: barite, talc, bentonite, heavy calcium carbonate, etc.
3. New materials: mobile phone casing powder, printer toner, graphite powder, etc.
4. Dry ultrafine grinding and deep processing of materials with a Mohs hardness of 4 or less.
