1.Description of coal ash dryer:
The new professional drying equipment is mainly consists of rotor, shed plate, transmission device, support device, seal ring, and other spare parts.
The coal ash dryer has the advantagesofreasonable structure, excellent manufacture, high output, lowenergyconsumption, convenient operation and so on.
The coal ash dryer is applicable forparticlematerials, and is also applicable for paste and viscousmaterials whichare mingled with particle materials, or materials whosewater content ishigh.
The coal ash dryer has the advantages oflargeproduction volume, wide application range, small flow resistance,largeadjustable range, and convenient operation, etc.
2.Working principle of coal ash dryer
1\Coal ash entered the inner layer of three-layer rollerthroughfeeding device to be fair current dried. Coal ash iscontinuouslyshoveled up by shoveling plate. And it falls down in aspiral scatter torealize its heat exchange.
2\Materials move to the other end of inner layer and enter intothemiddle layer to have counter-current drying. Materials is beingmovedon in a two steps forward and one step backward way.
3\The middle layer materials both absorb the heat from innerlayerand middle layer. At the same time,thus it extending the dryingtime andreach the best drying state.
4\Then materials move to the other side of middle layer andenterinto outer layer. Materials move in a rectangular multi-loop way.Welldried materials will be quickly discharges by hot air. Not welldriedmaterials will back to rectangular multi-loop and again to bedrieduntil it is well dried.
3. Advantages of coal ash dryer:
1). Reasonable structure,
2). High efficiency,
3). Low energy consumption
4). Convenient for transportation.
5). The investment required is 1/6 of the imported products
6). It will ensure you the final material a moisture below 0.5% which is the first product of ash and slag product line
7).Cylinder self-insulation thermal efficiency ashighas 80% (traditionalmonocular dryer thermal efficiency was only 35%)toimprove thermalefficiency of 45%
8). Fuel, kerosene vapor applicable, 20mm below the block to dry powder material feed pellets
9).Dryer than the monocular area of about 50% reduction, 50% reduction incivil engineering, power consumption decreased to 60%.
10). Use and manufacture than ordinary steel, alloy steel wear plate 4 times
11). Can be customized easily control the required final moisture indicator
12). Outlet temperature is low, dust removal device a long time
13). The size of gears without using the tugs turn
