Fluid Bed Jet Mill For Pharmaceuticals/ Pesticides

Short Description:

DCF series jet mill is a fluid bed jet mill which features opposed grinding nozzles and a dynamic classifier. Air or inert gas at elevated pressure is injected through specially designed nozzles directly into the grinding chamber of the mill, creating a sonic or supersonic grinding stream. Raw feed is automatically introduced to the mill chamber by an interlocked feed control system.

  1. Brief Introduction:

The agitation provided by the grinding chamber and nozzle design cause particles to become entrained in the air or inert gas stream. Particle size reduction is accomplished by high velocity collisions between particles. Small particles are then swept towards the classifier which rotates at high speed above the grinding. The speed of the classifier is preset for the proper sized product and is electronically controlled. Material which is fluidized fine enough to overcome the inertial force generated by the classifier escapes the jet mill and is collected as product. Oversized particles are recycled by the classifier back into the grinding chamber for further reduction.

With the advanced design of the integrated, dynamic classifier, particle size distribution can be more easily controlled. Efficient use of compressed air and total system automation ensure manufactured product is of the highest quality. Capable of grinding dry powders to 0.5~45 micron averages with specific top size and/or bottom size requirements.
