Introduction

QLH air mixer is used for mixing large batches of dry bulk materials. The material mixing of air mixer is basёd on the principle of high kinetic energy when the pressure of compressed air is rapidly released to normal pressure. Compressed air is pulsed into the material in an upward circular pattern. There is no need for mixing paddle or blade to participate in the mixing process. The smooth inner silo surfaces can also pre­vent buildup during mixing process. The mixing process can be controlled by the duration and frequency of air pulses, and by the pressure and volume of air.

Working Principle

■ Feeding cycle
The lower discharge cone valve is closed, the feed valve and exhaust valve are opened, and the material enters the mixer by gravity. During the feeding process, the material dust carried by the replaced air will be collected by collecting bags when passing through the filter, and will fall back into the mixer by gravity.
■ Mixing period
When the feed valve is closed, the compressed air flows through the mixing head from bottom to top to form a spiral pulse air flow, which lifts, moves and turns the material to achieve uniform mixing. The compressed air entering the mixer is discharged through the exhaust valve, and the attached materials or dust are effec­tively blocked when passing through the dust filter, and fall back into the mixer under the action of pneumatic pulse back blowing.
■ Discharge period
The vent valve is closed, the discharge cone valve is lifted, and the material is discharged by gravity or by pneumatic pressure.
