The Haarslev Rotary Drum Dryer for Sludge is a directly fired, single pass, rotary drum drying system with advanced sizing screening and granulation techniques producing a dust free granule suitable for reuse in agriculture and as fuel.
The drying system is offered as a complete system including the latest in safety enhancements in full compliance with NFPS/ATEX regulations and includes a sophisticated process control system for both safety compliance and the possibility of unattended operations at night.
The hot air stream is provided by a direct-fired gas burner normally operating with natural- and bio-gas. This generates high inlet temperatures for rapid surface heating and immediate pathogen destruction. The process maintains a safe low oxygen atmosphere inside the dryer loop. Recirculation of hot gas reduces thermal energy consumption.
A range of fuels including natural gas, synthesis gas, methane, LPG, oil, coal or bio-gas can be used. It can also be supplied with indirect heating systems utilising waste heat from e.g. turbine exhaust gases.
Downtime is the worst for all companies. You just have to avoid it at all costs. Our systems have been designed to ensure maximum uptime. Haarslev Global Services department helps keep your plant running reliably, efficiently and profitably every day of the year.
Highly trained experts are available to give you the best advice when it comes to mastering your processes and by implementing the right procedures for maintenance and spare parts stock, you will be able to:
One of the more common variations between dryers is the heat source. Does the dryer use waste heat, or is it direct fired, or is it indirect fired? What sort of fuel is used to generate the heat? Is it biomass, coal, natural gas, or a bi-product of the plants main process? All of these factors are important to consider when choosing a dryer.
Flash Dryers A Flash Dryer uses ductwork, which acts as a container for the uniform transfer of thermal energy from a hot gas stream to a moisture laden product, for the purpose of moisture reduction in the product. For proper drying the particle size must be uniform and relatively small. Wet product is introduced in the gas stream where the moisture is flashed off, and then the dried product is removed from the gas stream.
Fluid Bed Dryer A Fluid Bed Dryer uses a container equipped with vertical jets of hot gases for the uniform transfer of thermal energy from a hot gas stream to a moisture laden product, for the purpose of moisture reduction in the product. For proper drying the particle must have near spherical shape as well as uniform small size and moisture content. The wet product must be uniformly introduced into the drying gas stream where the moisture is flashed off. The dried product is removed from the exiting gas stream.
Rotary Dryers A Rotary Dryer uses a rotating cylindrical drum, which acts as a container for the uniform transfer of thermal energy from a hot gas stream to a moisture laden product, for the purpose of moisture reduction in the product. Wet product is introduced into the inlet of the drum where it is dried as it is conveyed to the drums outlet. The drum is equipped with flighting to disperse the product into the drying gas stream as the drum rotates. The product can either be conveyed pneumatically or it can be conveyed by gravity if the drum is on a slope. There are several different types of rotary dryers and they can be used in many different applications.
Steam Tube Dryer A Steam Tube Dryer is a constant temperature drying process. The drying process always takes place at the steams saturation temperature for the steams pressure. Steam Tube Dryers use a rotary drum for the drying vessel and product is handled in a Steam Tube Dryer similar to a Rotary Dryer. Product can be conveyed with gravity, screw flighting, or pneumatics.
Weve built a reputation on building the best rotary dryers in the industry. All of our dryers are custom designed to suit the unique processing needs of your material. Whether you require low or high inlet temperatures, short or long residence times, counter current or co-current flow, FEECOs design team can design a rotary drum dryer for your application.
Rotary dryers are a highly efficient industrial drying option for bulk solids. They are often chosen for their robust processing capabilities and their ability to produce uniform results despite variance in feedstock.
The drum is positioned at a slight horizontal slope to allow gravity to assist in moving material through the drum. As the drum rotates, lifting flights pick up the material and drop it through the air stream in order to maximize heat transfer efficiency. When working with agglomerates, the tumbling action imparted by the dryer offers the added benefit of further rounding and polishing the granules.
All FEECO equipment and process systems can be outfitted with the latest in automation controls from Rockwell Automation. The unique combination of proprietary Rockwell Automation controls and software, combined with our extensive experience in process design and enhancements with hundreds of materials provides an unparalleled experience for customers seeking innovative process solutions and equipment.
Rotary dryers are known as the workhorse of industrial dryers. They are able to process a wide variety of materials, and can lend a hand in nearly any industry requiring industrial drying solutions. Some of the most common industries and materials in which rotary dryers are employed include:
Unlike direct dryers, indirect dryers do not rely on direct contact between the material and process gas to dry the material. Instead, the rotating drum is enclosed in a furnace, which is externally heated. Contact with the heated drum shell is what dries the material.

Low grade heat (T<55C) recovered to enhance efficiency of textile dryer.Energy recovery methods investigated: recirculation (EGR) and recuperation.Demonstrated energy savings of 9% (EGR) and 15% (recuperation) over baseline.Reduction in drying time by 164s (EGR) and 216s (recuperation).Model predictions are in good agreement (AAD<7%) with experiments.
Thermal drying is energy intensive due to the unavoidable thermodynamic constraint of supplying sufficient energy to evaporate the water (hfg>2000kJkg1). Textile dryers only use about half (55%) of the total input energy for drying. To reduce the wasted energy, exhaust gas recirculation and waste heat recovery using a recuperative heat exchanger are investigated numerically and experimentally. The two methods aim to recover energy from the exhaust stream typically at T<55C for most of the drying period. Experiments are conducted on a commercial gas-fired tumble dryer. A theoretical model is developed to simulate and optimize the drying process. Recirculating the hot humid exhaust gases improves heat and mass transfer in the drum; however, the high humidity ratio of the recirculated air is not amenable to enhancing evaporation. An optimal recirculation ratio of 51% is found to reduce the specific moisture extraction ratio and drying time by 9% and 164s, respectively. To avoid the rise in humidity associated with recirculation, a compact plate-fin heat exchanger is used to recuperatively preheat the air entering the combustor. Energy savings of 15% and reduction in drying time by 216s over the baseline case are estimated. The predicted data demonstrate good agreement with experiments.
