3 Static separators: Introduction: The static separator is like the cyclone a simple mechanical device commonly used in the grinding circuits to remove relatively large particles from gas streams. Static separators are relatively inexpensive since they have no moving parts and they are easy to operate.

The basic job of a separator is to separate onspec material from oversize. You do not want this oversize material entering the product stream; it needs to be recirculated through the grinding process. But you also do not want to recirculate onspec material. That wastes energy and raises costs. Getting this balance is key to separator efficiency.
