Sometimes, it may occur that material combustion in coal rotary dryer during the operation of coal rotary dryer. Material combustion in coal rotary dryer not only will cause panic of the customers, but also cause serious economic losses. So what are the causes of material combustion in coal rotary dryer when it running?

First, the volume of coal rotary dryer is too small

If the volume of coal rotary dryer is too small, but must be a lot of drying material, then ratio of exudative water of the material will not meet the standard. Internal heat source device of dryer equipment is not sufficient to completely dry the material moisture, and the customer can only choose forced to increase the temperature of the heat source device, to dry the material. If you want to increase production, and increase the heat source, the result is dry shell  internal combustion. Therefore, if you really need drying a lot of materials, choose large models of drying equipment for processing materials.

Second, the seal of coal rotary dryer is not good

If the seal of coal rotary dryer is not good, there will be burning. Drying equipment is usually sealed to dry material, if the seal may be drying shell interior design problems, and there may be excessive ventilation. Dryer equipment with ventilation system, if the ventilation is too large, drying equipment, internal fire will be upwind and up, the fire will be too much material inside the drum combustion phenomenon, resulting in a large number of materials were burned. Therefore, the newly purchased drying equipment test machine, it is necessary to check the seal and the installation is in line with national standards, after checking to determine the quality of equipment.

Third, drying materials can not be sent away in time

If the coal rotary dryer inside the material can not be sent away in time, it will result in drying material burning phenomenon in the dryer internal heat source reaches a certain temperature, the material contained in the water will be pumped. The material will continue to absorb heat, and its own temperature will be higher and higher, until the material absorbs a certain heat source to reach the point of combustion, the material will be on fire phenomenon, it is possible that the water content of the material can not be sent out, Will lead to a big fire. Therefore, in the drying of materials, it also regularly check inside of the coal rotary dryer to whether the normal flow of materials, if the flow rate is too slow to reduce the supply of materials, until normal flow of materials can continue to feed.
