Jet mill is one of the most important superfine crushing equipment, and the fineness of the product is generally up to 1-45μm.

working principle:

The high-speed flow field is formed by high-pressure air, inert gas or superheated steam expansion and cooling, and the animal particles are collided, rubbed and sheared in the jet flow field to realize material refinement. Common types include flat type, fluidized bed reverse jet type, circulating tube type, counter-injection type, target type and other models, and dozens of specifications.

Flat airflow mill
Fluidized bed jet mill
Circulating tube type jet mill
Performance characteristics:

Advantages: the product has the characteristics of fine particle size, narrow particle size distribution, smooth particle surface, regular particle shape, high purity, high activity, good dispersibility and low pulverization temperature.

Disadvantages: high equipment manufacturing cost, large one-time investment, high energy consumption, and high processing cost of powder.
