LIPU Coal Slime Dryer Machines are designed to reduce moisture in coal slime through rotary drying. The system configuration can be selected according to feed moisture, target moisture, throughput, heat source, and site conditions.
Delivery Time and Warranty: Confirmed for Each Order
Coal slime is a fine, moisture-rich by-product generated during coal washing and processing. Its high moisture content can make storage, handling, transport, and reuse more difficult.
A coal slime dryer uses a controlled drying process to reduce moisture before the material moves to storage or a downstream application. The suitable configuration depends on feed properties, required capacity, target moisture, heat source, and site conditions.
Dried coal slime may be used or further processed according to its quality and the requirements of the receiving process. Potential applications include:
The appropriate end use depends on coal slime composition, drying results, local regulations, and customer requirements. Confirm material suitability before selecting a downstream application.
Coal slime is fed into the rotary drum at a controlled rate. As the drum rotates, internal lifting flights raise and release the material so it contacts the drying gas. The material moves through the drum while moisture evaporates. Dried material exits at the discharge end, and exhaust gas is routed to dust collection or treatment equipment as required.
A typical process includes:
Drying results depend on feed moisture, particle size, throughput, heat source, and operating conditions. The process illustration shows a typical layout; final equipment and flow direction should be confirmed for the selected design.
A complete drying line may include a feed hopper, metering conveyor, rotary dryer, heat-source system, product conveyor, and exhaust-treatment equipment. The configuration is determined by material characteristics, required throughput, available utilities, emissions requirements, and plant layout.
A cyclone, bag filter, or other dust-control equipment may be included when required by the process and environmental conditions. Equipment selection should be confirmed for each project rather than assumed to be identical across installations.
The rotary dryer system may include the drum, internal lifting flights, support rollers, girth gear, drive system, feed and discharge sections, and auxiliary equipment. Component design and arrangement vary by model and project.
Regular inspection of the drive, support, sealing, and conveying components helps operators plan routine maintenance. Follow the equipment manual and site-specific maintenance procedures.
Actual capacity and drying performance depend on feed properties, moisture reduction required, heat source, and operating conditions.

When requesting a configuration, provide:
These details help determine the dryer size, heat-source arrangement, and supporting equipment. Material testing may be recommended when feed properties vary or the target moisture is critical.
Coal slime dryer systems can be integrated into existing or new processing lines. The layout may include feeding, rotary drying, material conveying, and exhaust handling equipment, configured to suit the plant’s capacity, heat source, and site conditions.
What information is needed to select a coal slime dryer?
Provide the feed rate, particle-size range, initial and target moisture, available heat source, and site conditions. These details help determine the dryer configuration and auxiliary equipment.
Can the dryer process sticky coal slime?
It may be possible, but suitability depends on the material’s moisture, stickiness, particle size, and handling behavior. Provide a representative sample or material data for evaluation.
Does the listed capacity apply to every coal slime?
No. Actual throughput depends on feed characteristics, required moisture reduction, heat source, and operating conditions. Confirm the capacity basis for the selected model.
What heat sources are available?
Heat-source options depend on the project design, fuel availability, local requirements, and material characteristics. Confirm suitable options with LIPU.
Is dust-collection equipment included?
Dust-control and exhaust-treatment equipment are selected according to project requirements. A cyclone, bag filter, or other equipment may be considered where appropriate.
