TZ inertial gravity 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. 

 

Application:

Dry sand making production line

Features;
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.

Advantage:
1. Low cost of maintenance and operation
2. Reduce the moisture content, minimize the cost
3. Develop the market of granularity of **0 mu material.

Principle:
By the control of air flow, flow direction and gravity, the inertial gravity classifier can realize **4.*5mm material classification. The fed material and primary air enters into the classifier from the top, the direction of air flow changes **0°, and leaves the classifier with fine particles through the blades. The coarse particles falls down to the bottom of the classifier because of the gravity itself then can’t be flowed with the air, and discharges from a valve. 
Secondary air blowing from the bottom of the blades passes the curtain of falling particles mandatorily. These coarse particles nearing the classification point enters into the eddy in the heart-shaped cavity secondary air flow which changed its director. When enter the classifier, the captured fine particles and other particles pulled by the eddy all gather into the powder collector and will be recycled at last. 
The air throttle of secondary air can be adjusted simply by hand. It can change the particles granularity of classification. There is no moving part in material flow area, so the maintenance requirement of this machine is the lowest. For abrasive material, liners are used in some area in order to guarantee the long operating life of equipment.
