Product Description

Coal slime dryer

Coal slime from post-flotation concentrate, coal washing process or coal mining processes are of great recycling value and also environmentally necessary for recycling. Coal slime drying may adopt several different types of dryers like rotary dryer, fluid-bed dryer,etc. according to the state of coal slime and drying requirement; of which rotary dryers are most commonly installed in practice due to its effectiveness in manufacturing and operation cost.

Our factory has a long history in design and build of specialized rotary dryers for processing coal slimes in coal preparation plants.

The slime drying system mainly consist of rotary shell, combustion system, seating rollers, special designed internal breaking &cleaning devices, shell sealing and transmission devices, etc.. Fuel is adjustable to match each individual installation condition. The unparalleled advantage of this system is that it has a unique internal structure that can effectively break up big lumps of sticky coal and clean sticky materials off the lifters, thus increase heat transfer efficiency and achieve designed requirements on moisture content and granule sizes.

Considering the nature of coal slime, this dryer is divided into four drying zones: the first zone is buffer zone where wet slime enters into the dryer and contact with the hot air evaporating at high rate; wet feed are moved to the second zone with big angle lifters before sticking. The second zone is self-cleaning zone where wet slime move in cascade motion and is prone to stick to the shell while falling down from lifters. Specially designed self-cleaning device is installed to remove the shell sticking, meanwhile big lumps of sticky material is also scattered by the cleaning devices, this further increase heat transfer. The third zone is tilt lifter zone where the coal slime is in loose state with low moisture content, which is not sticky anymore. The forth zone is output zone where material slide to the output along with rolling shell. There are no lifters in this zone.

Main features:

1. Designed with high torque, high overloading capacity, low operation cost.

2. Concurrent drying to avoid possibility of ignition, higher evaporation rate due to hot combustion air and wet coal lime entering from the same side, lower exhaust air temperature and higher heat efficiency.

3. Operating parameters are adjustable to varied state of coal slime to ensure constant and stable cascade motion of material and increase heat transfer.

4. Upgraded feeding and discharging system to avoid possibility of feed clogging, interruptions, non-uniformity or reverting, and thus load of dust removing system is less.

5. Specially designed flight and breaking system further enhances its self-cleaning and heat transfer capability and outcome shell sticking problem, thus could handle varied materials with varied moisture content and viscosity (highly adaptable to ….)

6. Output sizes and moisture is controllable according to each individual customer’s demand. Dried coal slime moisture can be less than 8% and size below 8mm.

The moisture content is very important in determining the usability of coal for further technological processing. In coal, the moisture may be present in the form of surface or hygroscopic moisture. Surface moisture is not dependent on the coal type because it depends on the classification and washing processes performed in the coal mine and on the soaking process during transport and storage. The evaporation of surface moisture takes place in the first drying period at a constant drying rate. Hygroscopic moisture depends on the rank of coal; it decreases with the age of coal. The evaporation of hygroscopic moisture takes place in the second drying period at a falling drying rate.

The microwave frequency thawing equipment with microwave frequency of 915MHz and output power of 20kw-200kw is above. For food processing enterprises such as chain fast food industry in China, food thawing is provided, and the improvement of food thawing technology in China is also renewed. The benefit is not only "farsightedness", but also at the foot of the eyes. According to experts, the traditional food thawing are based on heat conduction method, material surface temperature is higher than the internal temperature in the thawing process, inevitably there will be drop loss, which will increase the business loss. If merchants use microwave dryer, Single microwave Shell Rotary Drum Dryer for Coal Slime Drying Turnkey Service! power, material temperature and transmission speed can be used to achieve adjustable linkage, and the overall heating process control advantages can greatly reduce material consumption and improve food utilization.

microwave dryer advantages of equipment

1, microwave dryer, short, fast

Conventional thermal sterilization is used to transmit heat from the surface of the food to the interior through heat conduction, convection, or radiation. It often takes a long time to get the germicidal temperature. The Single microwave Shell Rotary Drum Dryer for Coal Slime Drying Turnkey Service! is the direct interaction between microwave energy and microorganisms such as food and bacteria. The interaction between heat effect and non thermal effect can achieve fast warming and bactericidal action, and the processing time is greatly reduced. The sterilization effect of various materials is usually 3-5 minutes.

2, Single microwave Shell Rotary Drum Dryer for Coal Slime Drying Turnkey Service! low temperature sterilization keep the nutrition and traditional flavor The Single microwave Shell Rotary Drum Dryer for Coal Slime Drying Turnkey Service! is through special heat and non thermal effect sterilization, compared with conventional thermal sterilization, it can get the desired disinfection effect at relatively low temperature and short time. Practice shows that the general sterilization temperature can reach the effect at 75-80 degrees centigrade. In addition, microwave dryer processed foods can retain more nutrients and color, aroma, taste, shape and other flavors, and have puffing effect. For example, the vitamin C retained in vegetables treated by conventional heat treatment is 46-50%, while that in microwave treatment is 60-90%, while that in conventional heating is 58%, while that in microwave heating is 84%.
