Three-cylinder Dryer 

Three drum dryer in the wet material drying equipment products, the three-cylinder rotary dryer in monocular rotary dryer based on the improvement of energy-efficient products. By a number of companies, a number of industry applications, and achieved good results. Rotary three drum dryer to improve the internal structure of the original single cylinder dryer, increased pre-baked before the wet material into the dryer and the wet material to extend the drying time in the machine, sealing, insulation and reasonable supporting measures plus make dryer production capacity compared to the original single cylinder dryer improved 50-80%, unit volume of evaporation intensity of up to 120-180kg / m3, standard coal consumption of only 6-8kg / t. Its advanced technology, reasonable operational parameters, the operation is simple and feasible, it is widely used in various sectors of the slag, clay, coal, iron, ore and other mixed materials, construction of dry mortar, yellow sand, etc. as well as chemical, foundry and other industries of raw materials drying.

Three drum dryer performance advantages:

1, Dryer scientific and rational, energy efficient. Material of the inner cylinder and hot air to radiation, convection, conduction, heat exchange form, the outer cylinder of heat exchange by conduction, convection and with the form. Dryer high thermal efficiency, energy saving effect is remarkable. After testing, the thermal efficiency is much higher than conventional dryer 50% level. After the device is put into use, the economizer effect is remarkable.
2, the machine uses hot air downstream drying materials and technology, a wide range. It can adapt to drying clay, coal, slag, iron and other raw materials, also suitable for drying a variety of bulk materials metallurgical and chemical sectors. Compact structure. Machine level layout, the use of roller bearings, gear size canceled, replaced by roller drive, to make installation easier, more simple, more reliable, higher operating rate.
3, the external surface area of ​​the aircraft than the single cylinder rotary dryer to reduce more than 30%, and the outer tube inner cylinder has a thermal insulation effect, the outer cylinder surface temperature is low, less heat loss in energy efficient at the same time, greatly improved the working environment and working conditions.
4, a variety of lifting plate design, angular lifting plate lifting plate with the words organic combination of the material and the hot flue gas exchange more fully, reducing the dryer cylinder body "tunnel" generation mechanism.
5, the use of frequency control, adjust the cylinder speed, according to the water into the machine, production requirements, appropriate speed, to ensure that meet the needs of the next step. Automatic temperature control system, make the operation more convenient.

Folding works

Material from the feeding device into the inner rotary drum and achieve downstream drying, the material in the inner constantly took a copy board, scattered spiral traveling type heat exchange, material movement to the other end of the inner layer into the middle, countercurrent drying, the material is repeated constantly in the middle Yang Jin, was a step back and two steps forward travel mode, both fully absorb the material in the middle inner cylinder the heat, and the middle cylinder to absorb heat, while extending the drying time, the best material in this dry state. Material line to the middle the other end fall into the outer, the material in the outer drum rectangular multi-loop approach road, to reach the drying effect of the material in the hot action fast marching discharge roller, did not reach the drying effect of the wet material and not due to weight fast travel, the material within this rectangle copy board is fully dried, thereby completing the drying purposes.

Folding Key Features:

1, equipment investment is required for imported products 1/6.
2, materials final moisture to ensure 0.5% or less, dry-mixed mortar and slag powder production line product of choice.
3, cylinder self-insulation thermal efficiency up to 70% (traditional monocular dryer thermal efficiency of only 35%), to improve the thermal efficiency of 35%.
4, the fuel can be adapted to coal, oil and gas. You can bake 20mm below the block material, pellets and powder materials.
5, than monocular dryer covers an area of ​​about 50% reduction, reduce construction investment is about 50%, power consumption reduced by 60%.
6, according to user requirements easily control the desired final moisture indicators.
7, the outlet temperature is low, dust removal equipment long time.
8, no gear size, the use of wheel drive.
Three drum dryer has a compact, simple structure, reasonable layout, improve the material and heat exchange rate of thermal energy, so that the material drying effect is good; less investment basis, only one-half of the same production single cylinder drying machine reduce the time investment; reliable operation, low energy consumption, high thermal efficiency; at the same time, easy to implement automatic control, reduce operating personnel, labor-saving resources.
Three drum dryer is mainly used for drying certain humidity and particle size range of materials. Such as sand, sand, slag, cinder, small
Three drum dryer
Size clay, and other small particles of material is not afraid of high temperature and dust soiled. After drying the moisture content of materials can reach 1-0.5% or less.
