The air classifier is a new type of classifier developed by Tarzan according to customers'reaction and requirement. It is always used together with a duster and without motors. It heavily reduced the investment cost and operation cost, and is mostly used for the separation of excessive powder in dry sand making line. TZ inertial gravity classifier is a new type of classifier developed by Tarzan according to customers'reaction and requirement. Advantages of air classifier 1.Easy to adjust, 4 parts for adjustment as: material falls control, first ventilation control, secondary ventilation control, finished volume control. It can control the air flow and powder content very conveniently. 2.Power saving, previous solution is classifier+duster, but at this moment no motor in this kind of equipment, the main power is focus on duster. Thus it saves the electricity input. 3.Simple structure, few material contract parts, little abrasion, low cost of maintenance. 4.Low cost ...
