Granular Material Flyash Industrial Drying Machinery , Easy To Install

High Thermal Efficiency Granular Material Industrial Drying Equipment For Flyash

Material Description :

Granular material generally refers to the material with good fluidity, not easy to be bonded and without

much initial water content, such as, yellow sand in the dry powder mortar industry, all kinds of specific

dimensioned sand used in the foundry industry, blast furnace slag used in the building materials cement

industry, small size clay, small particles of dust material, limestone, quartz sand, slag, iron ore, sulfuric

acid slag, iron ore powder, bentonite, fly ash, quartz sand, the sand of the sea and pomegranate sand,

etc. used in the chemical industry, which are anti chemical changes and anti-high temperature.

Process Flow :

The sand will be fed into the hopper by the wheel loader after a period of time natural dehydration, and

fed to the conveying device by the feeder at the bottom of the hopper, and then transported to the

feeding head end of the dryer. When material enters the dryer, the special feeder is adopted to do the

sealing in order to minimize the entry of the cool air.

The heat exchange happens with the hot air introduced from the heat passing through pipe while the

material is entering the dryer. The material is lifted up and moved forward with the rotation of the dryer,

enter the middle cylinder from the inner cylinder and return, and then move to the discharging end after

entering the outer cylinder. The special unloader is still adopted while the material is discharged from

the dryer to prevent the cool air and maximize the reduction of the entry of cool air, to increase the

efficiency of the dryer and reduce the pressure load of the induced draft fan and the burden of later stage

dust collecting.

According to the needs, the material can be transported to the finished products’ bin by the conveying

device or packed after discharging from the dryer. The air temperature at the discharging end will be

reduced to 80-120℃ with increased humidity, After the heat exchange, the air temperature in the

discharging end is reduced to 80-120℃ with the increased humidity, under the function of the induced

draft fan, it will be discharged into the atmosphere after the primary and secondary dust remover

processing.

System Advantages :

1. High thermal efficiency

Heat preservation material with high heat resistance, combined with feature of the heat utilization of

three cylinder dryer, the energy saving effect is obvious.

2. Low equipment investment

The material temperature is <50℃, which can be directly entered into the material warehouse, and

cooling device is not required; tail gas temperature is low, the dust removal equipment is with longer

service life.

3. Small ground space, easy to install

Its covered area is 50% less than that of the single cylinder dryer, construction investment reduced by

50% and the electricity consumption is reduced by 60%, the layout of high thermal efficiency granular

material industrial drying equipment is compact with simple process flow.

4. High thermal efficiency

Advanced internal structure strengths heat exchange, that is to say, increasing thermal efficiency.
