No cold forming binder that is pulverized coal without binder, and rely on external forces shaping. Many countries have widely adopted this approach to manufacturing peat, lignite coal, as domestic fuel and industrial fuel. For bituminous coal and anthracite, due to their high degree of coalification, the more difficult it pulverized binder-free molding. Currently, the industry has not been widely used binder-free molding process, but research work around the world neither interrupted squeeze the ball machine, water wet coal rods of ammonia for industrial use (wet coal strip) also belong to this case. Pf binderless molding without adding a binder, not only save a lot of raw materials, and accordingly to maintain the carbon content of coal, and to simplify the molding process and so on, it is pulverized coal molding; an important development direction. Tumble dryers is a batch, continuous production of drying equipment, the main heating electric heating, steam heating, hot air heating. The main principle is uniformly tiled material on the belt, mesh belt use 12-60 purpose steel mesh belt, drag reciprocated by the actuator pressure pressure ball machine in the dryer, hot air flow through the material in between and over water vapor is discharged from the humidity and pore pressure ball machine equipment, so as to achieve the purpose of drying, box length is determined by a combination of standard segment pressure ball machine, in order to save space, can be dried into a multi-layered mechanism, a common Two-Room three, five two-compartment, length 6-40m, effective width of 0.6-3.0m.
