Example air classifier mill system Figure 3 shows a vertical air classifier mill installed in a closed-loop system. The system uses an inert gas, nitro-gen, rather than air to safely handle a potentially explosive material, and its closed-loop design allows the expensive inert gas to be recycled through the mill. (The closed-loop

Techno liquid nitrogen Plastic Cryogenic Pulverizer is mainly used to grind materials which cannot be ground at room temperature. The machinery adopts the heat exchange between liquid nitrogen and materials. When the crushed materials achieve at the brittle fractured state, it goes into mechanical pulverizing chamber and repeatedly impacts, collides, shears, mills, eventually becomes fine powder.

Coal is reduced in size by crushing and pulverizing. Pre-crushed coal can be economical for smaller units, especially those which are stoker fired. In a coal handling system, crushing is limited to a top size of 6 or 4mm. The devices most commonly used for crushing are the rotary breaker, the roll crusher and the hammer mill.
