How Pneumatic Blender Works? Blender is charged with powders to be blended in the blender either by pneumatic conveying or otherwise. Air is blown into powder bed through fluidizing cone After the powder in the vessel is completely fluidized, Agitating air pulses are introduced through bottom nozzle. Contd..

How Pneumatic Blender Works? Agitating pulse duration is about 300 to 500 milli seconds. Interval between pulse is around 20-35 seconds. After about 30 to 40 minutes pulsing is stopped and material is discharged through bottom nozzle While discharging fluidizing air is still blown in the material to avoid segregation of material.

Data Required For Designing Pneumatic Blender We need to know following properties of material. Particle Size (Maximum and Minimum) Standard deviation between particle sizes Fluidizing Property of Material/ Powder All above properties can be checked at our works.

Comparison between mechanical & Pneumatic Blending Mechanical Blenders Pneumatic Blenders For 5 T powder Blending Required time is about 3-4 Hrs Temperature rise of blend is about 20o to 30o C For 5 T blender about 30Kw is required for 4 hrs.= 120Kwhr Some Pigments are sensitive to temperature rise thus causing loss of quality For 5 T blending time is about 40 minutes. No Significant Temperature rise. Total Power consumption of 5kW for ½ Hr.= 2.5 kwhr. No temperature rise hence no loss of Quality
