Gastric Medicine Specialized Grinder

Working Principle:

The ZJ series utilizes high-speed airflow to accelerate materials to supersonic speeds, causing them to collide with each other at the intersection of nozzles. The fluidized bed jet mill employs multiple oppositely arranged nozzles to generate high-speed airflow, achieving ultra-fine grinding. The crushed materials are carried by the rising airflow into the classifier chamber of the classifier. Due to the high-speed rotation of the classifier rotor, particles are subjected to both the centrifugal force generated by the classifier rotor and the centripetal force produced by the viscous effect of the airflow. When the centrifugal force on the particles exceeds the centripetal force, i.e., coarse particles above the classification particle size return to the grinding chamber for further impact crushing, while fine particles are carried by the airflow into the cyclone separator and collector for collection, with the gas being discharged by the induced draft fan.

The ZJ Series Fluidized Bed Jet Mill is an upgraded product replacing traditional fluidized bed jet mills, opposed jet mills, horizontal jet mills, and other types of jet mills. The equipment mainly consists of a crushing main unit, a high-precision vortex classifier, a cyclone collector, a bag filter, and an air compressor. The **key feature** of this machine is the full utilization of jet energy.

Equipment Features ：

1. **Eco-friendly**: Low-temperature, medium-free crushing ensures high purity and physical properties of the product. The equipment operates under negative pressure, resulting in no dust pollution.

2. High Efficiency: Full utilization of jet energy improves crushing efficiency by 30% compared to traditional jet mills, with higher classification accuracy.

3. Minimal Equipment Wear: The "fluidized bed + vertical classifier" structure enables the processing of ultra-fine powders with high purity and extremely narrow particle size distribution, effectively avoiding wear on the classification components commonly seen in "fluidized bed + horizontal classifier" systems. Under the same material conditions, the service life of wear-prone parts is 20 times longer than that of similar international products. With minimal wear, it is especially suitable for ultra-fine grinding of high-purity, high-hardness materials.

4. High Yield: When producing products with a narrow particle size distribution, the yield rate is more than double that of traditional opposed-jet and fluidized-bed jet mills.

5. Multi-purpose: One machine serves multiple functions, capable of being used as both a grinder and a classifier. It offers a wide range of crushing particle sizes, with the product particle diameter adjustable arbitrarily within the range of 1-74 μm.

6. Intelligent: The equipment can achieve full automatic control, with simple operation, stable operation, and an excellent production environment.

7. Reasonable Design: The equipment has a compact structure, with no material accumulation or dead corners inside the main crushing unit. It is easy to disassemble, clean, sterilize, and convenient for switching between different types of crushed materials.

8. The entire system adopts automated control, enabling one-key start and stop. It is simple and convenient to operate and can be connected to the central control system for remote control.
