Rotary drum fruits and tea dross dryer/ sediment dryer / sands dryer

Introduction of China high quality hot sale rotary sand dryer/drying machine for drying sand:

 Three cylinder dryer is  Huadong machinery plant adopt the three cylinder drying principle developed a new generation of efficient, energy-saving drying machinery and equipment  with compact structure, simple structure, reasonable layout, according to the principle of work, the inner cylinder with different angles and spacing of the lifting plate and guide plate to ensure material drying under the action of gravity along the guide plate of the running track running, in the tube has sufficient residence time and good dispersity, resulting in material in the barrel and hot gas flow to fully exchange heat, increase the heat exchange area, enhancement per unit volume of evaporation amount, to complete the high efficiency and energy saving drying .

Scope of application :

Three cylinder drying machine apply to three cylinder structure it will make the heating time of raw material longer, reduce the heat source loss, increase the heat source and heating surface, reduce the equipment occupation, it is a highly efficient energy-saving drying equipment, suitable for drying a certain humidity, granular materials such as lime sand, viscosity sand, sand, sand, sand, river sand, artificial sand, mineral sand,  slag, blast furnace slag, cinder, slag, ore, metal powder, clay, kaolin, diatomite, perlite, granite, bauxite, gypsum, fly ash, coal, coke, coal, crystallization, drying light calcium carbonate and other dry materials, according to the different industries have the different aquirement for final material`s moisture , the  final drying moisture content can reach 1 - 0.5%

 The consist of China high quality hot sale rotary sand dryer/drying machine for drying sand:

This machine mainly consist by lifting machine, drying drum ,transmission device, pipeline, induced draft fan, hot blast furnace, dust collector and discharger .

Working principle of China high quality hot sale rotary sand dryer/drying machine for drying sand:

The material through conveying device into the inner drying  cylinder, the lifting board and stock guide what  fixed on inner cylinder to continue move like roll,rise, break up, it can form a transient heat insulation space ,during the material contact with heat exchange  and heat flow downstream planes through the inner cylinder to the tail, the material will be naturally drawn to the middle of the drying cylinder, countercurrent circulation operation, drying cylinder heat exchange area of material to the rear to enter the outer drying barrel downstream circulation drying operation again,under the  third drying low temperature exchange it can make full use of waste heat to increase the heat exchange area, greatly improved the water evaporation efficiency of the material, after three cylinder drying operations materials in a variety of action of long time contact with different levels of heat source. The drying purpose of high efficiency and energy saving is completed.

 Characteristic:

 1: The machine  increases into the wet material pre drying and prolonged wet material drying time, and sealing, thermal insulation and reasonable measures, the drying machine production capacity compared with the orginal drum drying machine  improved the 48-70%, unit volumetric evaporation intensity is up to 120-180kg/m3, standard coal consumption only for 6-8kg/t;

 2, The machine adopt three layer inner drying cylinder model to achieve high efficient drying structure, cylinder self thermal insulation efficiency up to 70% (the thermal efficiency of the traditional single cylinder drying machine is only 35%), the thermal efficiency is improved by 35%, the outer cylinder body temperature is no more than 60 degrees, exhaust gas temperatures < 120 degrees, the use of bag dust removal equipment up to more than 2 times, material initial moisture content of 15%, and the final water content under 0.5-1% . The machine is the priority of slag powder in cement plant, dry mortar production line and other various drying engineering .

 3: The drying principle, material in the barrel of the lifting plate and scraping plate and downstream countercurrent motion continue to achieve  radiation, convection and  heat exchange, drying machine has the advantages of high thermal efficiency, energy-saving effect is remarkable, after testing, thermal efficiency greatly exceed the level of conventional drying machine about 50% ;

 4: Internal lifting board and stock guide  with a variety of form binding. The effective combination of the angle form lifting board and gammadion lifting board make the material and hot flue gas exchange more sufficient, high thermal efficiency, drying quality is high;

 5: This machine adopts the internal sleeve tube design is better than t single cylinder drying machine reduce covers an area of about 50%, construction investment is reduced about 50%, the electricity consumption is reduced by 60%;

 6: The machine apply to  frequency conversion to adjust  the cylinder speed, according to the content water of the material into the machine, production requirements adjust appropriate speed, automatic temperature monitoring system, make the operation more convenient.

 7: According to customers need to adjust the hot blast stove, coal, oil, gas, anthracite, bituminous coal, coal gangue all as a source of fuel, to solve the problem of each area customers for heat source fuel.
