How Does a Micro Pulverizer Work for Chemical Processing?
The micro pulverizer operates on advanced principles of size reduction, ensuring precision and efficiency. Let’s break down its mechanism:
- Material Feeding: Raw materials are introduced through a hopper, which regulates the flow to ensure uniform processing.
- Impact Grinding: Inside the pulverizer, high-speed rotating components like hammers, blades, or pins strike the material with great force. This impact breaks down larger particles.
- Shear Forces: As the material passes through the grinding chamber, it is further reduced by shear forces generated between fixed and moving surfaces.
- Integrated Classifier: An inbuilt classifier segregates particles based on size. Finer particles pass through a screen or outlet, while larger particles are redirected for additional grinding.
- Collection System: The processed fine powder is collected through a discharge outlet, ready for further applications like mixing or packaging.
This system ensures efficiency, uniformity, and minimal material wastage, which is crucial in chemical processing.
