High EnerLD-efficient Rotary Coal Slime Dryer with Upgraded Design

Conventional thermal sterilization is carried out through heat conduction, convection or radiation to heat the food surface to the inside. To achieve the sterilization temperature, it often takes a long time. Microwave sterilization is a direct interaction of microwave energy and food and its bacteria. The interaction between heat effect and non thermal effect is faster than temperature and sterilization. The treatment time is greatly shortened, and the sterilization effect of various materials is usually 3-5 minutes.

High EnerLD-efficient Rotary Coal Slime Dryer with Upgraded Design of traditional Chinese medicine, also known as microwave traditional Chinese medicine dryer, microwave traditional Chinese medicine drying equipment, microwave medicine drying insecticidal, the same type of industrial microwave equipment, apply to heat-sensitive Chinese medicine, and valuable health herbs such as ginseng and other herbsdrying, sterilization processing.

Tunnel microwave herbs dryer is for drying and sterilizing medicinal materials and pills,for drying and sterilizing and heating materials in strip shape, cube shape,small&round shape,leaves type, powdery form as well as filter cake which have high water content and certain and certain viscosity. It is also used for sterilizing medicinal liquid before and after packing.

Rotary 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 lLD 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 fligLD 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.

Typical Technical Data of Coal Slime Dryer

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.

Our drying equipment factory was established in 1950s with technoloLD assistance from Russian experts. Since then the factory has never stopped pursuit of upgrade of our drying equipment, many specially designed dryers for challenging materials had been developed during even 1960s-1970s without any outside help. The spirit of constant pursuit on technoloLD upgrade and commitment to quality and process optimization had passed on from generations to generations.

Today, with an open mind and eagerness to better serve customers, we had learned from western counterparts, integrated European technoloLD into our products selectively according to our current industrial circuLDtances in China based on our past experiences, which makes our products more effective, competitive and much easier for customers to accept. We are proud of products that had provided numerous businessmen new opportunities and even more workers jobs, all of which had been indispensable in our social welfare improvement and industrial development.

Time had witnessed our growth and we shall never cease to change times with our products.

To all ambitious and hardworking entrepreneurs all over the world, we offer our products to change your tomorrow for the better and better. Please give us a call for your requests. We are at your disposal at any time.
