High Speed Centrifuge Spray Dryer Sodium Silicate Spray Drying process:




1.Outdoor air through effectively filter enter into heater, heating until its temperature reach the request of inlet gas temperature, through hot air pipeline reach to the hot air distributor which is at the top of drying tower, under the function of hot air distributor, air come into drying tower uniformly.




Material liquid (already after treatment) through screw pump sucked into high speed centrifugal atomizer which is at the top of drying tower. According to spray drying particle request, adjust the rotating speed of atomizer, let material liquid atomize into fog droplets, and contact with hot air, then from top to bottom drying into ideal products in drying tower.




Most products after drying through exhaust pipe which is at the bottom of drying tower to cyclone distrituber to collect the powder.

2.Material selection: spray dryer parts which are contact with hot air and material, stair railing and support are made of carbon steel; skeleton and frame are made of carbon steel.

3.Equipment processing: use argon welding, weld joint rub down smooth and polishing, no dead angle.

4.Drying tower straight cylinder install a door which has an observe hole, through this hole could observe the atomization situation on drying tower, open the door could clean and washing drying tower.

5.Electric control: electric cabinet use carbon steel material which has good heat dissipation performance. Inlet air temp. automatic control, it could be adjust automatic after set the inlet gas temperature degree, exhaust air temperature should be controlled manual.

According to products situation, adjust the flow rate of material feed pump, and control exhaust gas temperature. On the electric cabinet has inlet air temperature and exhaust air temperature display, and all operation buttons which are used to control equipment.
