Detailed Introduction:

I. Working Principle:

During operation, the material is first fed into the material bin, where a uniform feeder sends it into the pulverizing chamber. Compressed air undergoes rapid expansion and acceleration through nozzles, creating supersonic jets that form a centripetal counter-jet flow field at the bottom of the pulverizing chamber. The material in the chamber is fluidized under the action of pressure differences. The accelerated material converges at the intersection of multiple nozzles, resulting in intense impacts, collisions, and shearing, thereby achieving pulverization. The pulverized material then rises with the airflow to the classification zone. In the flow field generated by the high-speed turbine, coarse particles are thrown towards the wall under centrifugal force and fall back into the pulverizing chamber along with the decelerated coarse powder for re-pulverization. Meanwhile, the fine powder meeting the fineness requirements passes through the classifier vane channel and is conveyed through the exhaust pipe to the cyclone separator for collection as the final product. A small amount of fine powder undergoes further gas-solid separation in the bag filter, and the purified air is exhausted by the induced draft fan.

II. Technical Parameters:

Model	Feed Particle Size (mm)	Pulverizing Fineness (µm)	Production Capacity (kg/h)	Air Consumption (m³/min)	Air Pressure (MPa)	Installed Power (kw)
SCWN-10-2	≤3	5-15	50-300	10	0.7-1	74
SCWN-20-2	≤5	5-15	200-1200	20	0.7-1	160
SCWN-40-2	≤5	5-15	400-3000	40	0.7-1	310

III. Features:

Our innovative SCWN series featuring "fluidized bed + vortex classifier" efficiently processes superior toner powder for copiers, printers, and other applications. Key features of the equipment include:

Efficient Heat Dissipation: The fluidized pulverization state created by the supersonic adiabatic expansion of airflow absorbs a significant amount of heat generated during pulverization, enabling processing at room temperature or even lower.
Maximized Jet Energy Utilization: Efficient utilization of jet energy significantly enhances pulverizing efficiency.
Precise Classification: The high-efficiency and high-precision classifier establishes a complete and stable flow field, strictly controlling the generation of large particles and achieving excellent particle size distribution with a narrow range.
Excellent Particle Shape and High Yield: The fully fluidized state results in superior spherical particle shapes. Qualified fine powder is immediately separated, avoiding over-pulverization and achieving a yield rate of over 70%.
Uniform Particle Size Distribution: The steep and uniformly distributed particle sizes ensure better downstream usability of the product.
