Common problems and daily maintenance of coal slime dryer

一. How to solve the blockage

During the operation of the coal slime dryer, various mechanical failures will always be encountered, which are usually called common failures. The most common problem is the blockage of the dryer. The dryer is severely blocked by high-humidity and high-viscosity materials, which will directly affect the drying efficiency of the materials and seriously affect the economic benefits of the users. How can the problem of blockage in the coal slime dryer be solved? The following is a summary of the solution to the blockage failure of the coal slime drying equipment by Hongtong technicians:

1. Pre-drying treatment to reduce the humidity and viscosity of the material. Before drying the coal slime and sludge, it can be placed in the sun for one or two days to appropriately reduce the humidity of the material, thereby reducing the viscosity. Then, when the material enters the coal slime dryer for drying, the blockage will be reduced.
2. Turn on the dispersing device. When drying materials with high viscosity, a dispersing device needs to be installed and turned on in front of the cylinder of 

the coal slime dryer to disperse the coal slime to avoid sticking together and affecting the flow and drying of the material. There is also a cleaning device for the equipment, which can clean the inner cylinder wall in time to prevent the material from sticking to the wall.
3. Appropriately increase the heat and speed. In order to avoid blockage caused by material adhesion and accumulation, the staff can appropriately increase the speed of the cylinder to facilitate the flow of materials such as coal slime, and increase the internal heat to ensure sufficient drying operation.

二. Improve the drying effect of the coal slime dryer

The users of the coal slime dryer are more concerned about the drying effect of the dryer, which is mainly related to the production efficiency of the user's friends. Everyone knows that heat and temperature are indispensable when drying materials, so the drying effect of the peat dryer is directly related to its temperature control. If you want the moisture content of the wet coal slime to be dried to meet the requirements of later use, you need to control the temperature in the dryer barrel during the drying process. So, how to control the internal temperature of the coal slime dryer equipment?

This requires everyone to do the following:

1. To ensure the stability and moderation of the internal temperature of the coal slime dryer, the staff needs to operate the equipment and its accessories reasonably, and the two need to cooperate closely.

2. For example, the heat transfer and feeding amount of the hot air furnace should be coordinated well. The amount of heat is related to the amount of material in the barrel. If the feeding is increased, in order to ensure the drying effect, more heat is needed to evaporate the water; if there is less material in the barrel of the coal slime dryer, the heat transfer can be reduced to avoid excessive temperature in the barrel and damage the equipment. In addition, the dust collector should also cooperate well to discharge the internal exhaust gas in time to avoid moisture return, reduce the drying effect, and waste energy.

3. In addition, the internal air volume should be appropriate to maintain heat balance, and the speed of the coal slime dryer cylinder should be adjusted according to the situation, so as to make the equipment achieve the best drying effect.

三. Maintenance of coal slime dryer

No matter what kind of mechanical equipment is operated, it is necessary to pay attention to its daily maintenance work, so as to effectively reduce the incidence of mechanical failures and ensure the stability of equipment production efficiency. The same is true for coal slime dryers in industrial applications, and daily maintenance work must be done well. Many users do not understand the maintenance scope of coal slime drying equipment, so they cannot maintain the drying equipment well, which only causes frequent mechanical failures and directly affects the progress of drying production. Today, Hongtong Drying Experts will analyze and summarize the three main points of daily maintenance of coal slime dryer equipment for everyone:

1. Oiling of bearings
The best time for bearing oiling is once a day. Because the coal slime dryer carries too much, its internal bearing parts are prone to wear, and timely oiling can greatly reduce the wear of the bearings, so we must pay attention to this aspect.
2. Timely dust removal
Since the production environment of coal slime dryers is mostly outdoor work, it is easy to encounter some dust entering the drying equipment during production, which will affect the quality of our finished products. Therefore, we need to remove the internal dust in time to avoid trouble for our production.
3. Material particle size
I believe everyone knows that the particle size of the material has a great relationship with the drying speed of the coal slime dryer. Once the particle size of the material is too large, it will easily lead to a slow drying speed. If the particle size of the material is too small, it will cause a series of problems such as being blown away by the wind. Therefore, when we add materials to the coal slime dryer, we must pay attention to the particle size of the material. It should not be too large or too small. It is better to maintain the uniformity of the particle size of the material, so that the coal slime dryer can run stably.
