Product Description

Premium Coal Drum Dryer Equipment

Product Description

 

Zhengzhou Jiutian Technology Machinery Co., Ltd. stands as the pinnacle of expertise and authority in China's coal drying equipment sector. Renowned for our innovative research and development, Jiutian is the only enterprise in the coal slime drying industry in China that seamlessly integrates design, production, and sales under one roof. Over nearly two decades of rapid growth, we have established ourselves as the leading brand in China's drying equipment industry. Specializing in high-moisture content lignite and washed coal, we have meticulously developed the state-of-the-art coal rotary drying drum system. With 20 years of experience and relentless improvements, our products boast advanced technology, superior efficiency, low energy consumption, stable operation, user-friendly maintenance, and robust security and environmental standards. Preferred by users worldwide, over 100 sets of our coal drying equipment are operational across China and globally.
 

Our High Quality Single Cylinder Peat Coal Rotary Dryer Machine is engineered with a sophisticated dispersing device that disintegrates bonded slime, enhancing its exposure to hot air and significantly boosting heat utilization. This cutting-edge design ensures moisture content is reduced to less than 12% in one drying cycle, transforming the dried coal slime into a valuable, combustible resource.
 

Versatility defines our equipment, suitable for drying an extensive range of coal types including lignite, anthracite, lean coal, coking coal, fat coal, air fertilizer coal, gas coal, weakly caking coal, non-sticky coal, long flame coal, and more. Whether for coal washing, screening, raw coal, bituminous coal, tail coal, or middling coal, our customizable solutions are tailored to meet diverse customer requirements.

 

Working Principle

 

The Coal Drum Dryer system is an ingeniously designed mechanism, comprising a hot blast stove, belt feeding machine, drum dryer, belt discharging machine, induced draft fan, cyclone dust collector, bag filter (or wet dust collector), and an operation control system. Utilizing a downstream drying process, its operational principle unfolds as follows: Upon entering the drying drum, the wet material undergoes a meticulously orchestrated sequence of stages:

1. **Feeding Area:** In this initial stage, the coal enters and swiftly interacts with high-temperature hot air, causing rapid moisture evaporation. The material is then lifted by a guide plate at a steep angle and directed towards the next workspace.

2. **Copy Plate Area:** Here, the coal is lifted and cascaded by the copy board to form a material curtain. This ensures maximum contact with the hot air, leading to the rapid evaporation of moisture, which is then removed by the induced draft fan. In this area, the coal moisture content is reduced to below 15%, achieving the desired dryness level before proceeding to the final stage.

3. **Discharging Area:** No copy plates are present in this section. The material moves smoothly towards the discharge port, thus completing the drying cycle.

 

Product Features

 

<sup>Innovative Technical Structural Characteristics of Coal Drum Dryer
1. The advanced coal fixed-speed quantitative feeder revolutionizes coal feeding by ensuring uniformity in travel throughout the dryer. This innovation eradicates previous challenges such as intermittent feeding, material blockage, and fluctuating material volumes, thus enhancing evaporation intensity.
(1) A uniquely designed buffer silo and feeding mechanism effectively eliminate issues of intermittent feeding and abrupt material changes, ensuring consistent material supply.
(2) A high-inclination, unpowered screw propeller at the drum's feed end distributes wet coal slime evenly into the drying section. It also slices and breaks large chunks of wet coal slime for more efficient drying.
2. The dryer's internal structure is meticulously optimized to amplify the heat exchange area between the material and hot air, significantly boosting evaporation intensity.
(1) Continuous refinement of the drum's internal layout and lifting plates has culminated in our unique internal lifting plate structure and functional mixing section layout. This ensures uniform handling of coal without dead zones or gaps, maximizing heat exchange and accelerating the evaporation of moisture from the coal.
(2) Our patented layered drying technology for rotary drum dryers leverages the varying speeds at which different-sized granular materials are heated and travel inside the drum. This multi-component layered drying device ensures small granules do not over-dry and large granules receive even heating, guaranteeing uniform drying.
3. Our hot blast furnace selection and optimized internal design reduce air leakage, maintain oxygen content in hot air below 5%, and allow precise temperature adjustments between 700-1100°C. This provides a stable and uniform heat source, ensuring reliable high-intensity operation of the coal dryer.
4. Our advanced measurement and control technology system employs a computer operating platform and frequency conversion PLC control. This system interlocks and jointly controls process parameters like temperature, pressure, oxygen concentration, and equipment speed, enabling automatic detection and control with centralized and local switching functions for stable, optimal, and safe operation.
5. We have enhanced our dust collection system with a three-stage configuration: gravity sedimentation, cyclone dust collector, and wet/bag dust collector. This ensures that dust concentration is below 30mg/Nm3, meeting all exhaust emission standards.
6. Our pioneering modular design simplifies manufacturing, transportation, installation, and service, offering customers optimized design and convenience alongside maximum benefits.
7. Our innovative solution prevents water vapor from returning to the material as system temperature decreases during co-directional movement, enhancing drying efficiency and achieving deep dehydration.
8. The dryer features a fish scale or labyrinth sealing mode with expandable graphite filler type mechanical seal for double sealing. This ensures an airtight, oxygen-free operation, guaranteeing safety.</sup>
