Deduster can be many, and many duster parallels are used together.
Powder material of the present invention and liquid material mixing apparatus are work like this: close blow-off valve and charging valve, open intake valve, start blower fan, and mobile at effect downstream high-speed circulating in circulation canal of blower fan; Open charging valve and add powder, powder under the effect of high velocity air, form fluidisation state and in circulating line high-speed circulating flow; Start atomizer and add liquid material, be dispersed into the liquid material of particulate and the powder Quick uniform of fluidisation state mixes, between the compound of high degree of dispersion in air-flow and gas, carry out rapidly heat and exchange of moisture, moisture in compound is vaporized, the air-flow of separating with deduster is discharged through deduster exhaust outlet, and compound is dried; After being dried, open blow-off valve, compound is along with air-flow is discharged through blow-off valve.
In order to increase heating load, can in circulation line II, heater be installed.
Powder material of the present invention and liquid material mixing apparatus form circulation canal by blower fan, circulation line I, deduster, control valve, air inlet threeway, circulation line II, by charging valve, add powder material, by atomizer, add liquid material, under the airflow function producing at blower fan, powder material completes and mixes and be dried with liquid material in circulation canal, the air-flow that moisture is separated with deduster is discharged, and device structure is simple, easy to operate, rate of drying is fast.
