Jet Mills
Jet Mill
Jet mill technology is a widely used grinding method, especially in applications where very fine particles of hard materials with high purity must be obtained.
* Controlled grain size obtaining d50 1 -50 mic.
* Environmentally friendly with its closed system, dust-free and low noise level
* Ease of commissioning and operation thanks to automation
* High and low pressure operation
* Grinding and separation are done simultaneously thanks to its compact structure. Occupy less area
* Protection against wear with steel, stainless and ceramic materials
* Suitable for hard and abrasive materials
* Possibility of grinding without heat
After the high pressure air or gases (nitrogen or steam) compressed in the compressor are filtered and dried, they are sprayed into the grinding chamber with the nozzles in the jet mill. Grinding occurs when the air flow intersects with multiple nozzles and the materials collide with each other. The ground materials are carried to the separator by the suction of the fan. The coarse and fine materials are separated by the strong centrifugal force created by the separator rotating at high speed. The desired grain size is obtained precisely depending on the rotation speed of the separator. Fine grained products are separated with the help of a cyclone and filter and used as a product. Coarse grains cannot pass through the separator and go to the grinding area to be ground again. In this way, a product with a constant capacity is obtained depending on the mill size.

Test Center
Tests are carried out in the test unit with the customers' own materials, and performance
tests such as capacity and energy are determined, and the appropriate machine is selected for the customer.
