rotary drum dryer drying system, working principle and details

rotary drum dryer drying system, working principle and details

Rotary dryer or rotary drum dryer is widely used to dry humidity granularity materials in the industries of mineral dressing, building material, metallurgy and chemical, coal mining, etc. Wide supply scope and simple operation are itsmain features, materials should be dried to 3-10% water content tomeet the demands forbriquetting.

The material is fed in the rotary drum dryer by the conveyor, and whenits coming through the cylinder, the hot air will flow from it and makes it dried,. The dried material will be collected at the output.

In this drying process, the material will move as the cylinder rotation. With the gravity, the material will fall from high-end to low-end. There are also copy boards in the dryer to raise the material, so that the material and hot airs contact surface area increases, which helps to increase the drying rate and let the material forward.

1. At the input area, the hot air is much higher than the raw material which leads a rapid heat exchange between the hot air and the raw material,moisture becomes easy to evaporate. This heat way is suitable for high moisture materials.

2. For the viscous materials, when it feeds into the dryer, as the rapid waterevaporates, the moisture down and helps to reduce the bonding rate, the easier-move material increase the drying efficiency.

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.

Since 1948 more than 500 dryers have been installed with the MPS (multi-pass-system) system. Traditionally the focus was on the agricultural area (as an example alfalfa (lucerne) is used as horse feed), but has been changed more to the alternative fuel area now.

In the alternative fuel market biomass (wood residue) is dried for the production of white pellets, brown pellets or black pellets. In each of these processes drum dryers can decrease the moisture to the desired level for downstream process steps. ANDRITZ Vandenbroek rotary drum dryers are available for evaporation capacities from 3-35 tons water per hour.

Waste is considered as valuable raw material for the production of energy. Municipal Solid Waste (MSW) can be divided in the organic fraction (wood waste, wood trimming, etc.) and Refused Derived Fuel (RDF, i.e. plastics, paper, etc.). This RDF fraction (normally moisture content of 35-40%) can be enhanced to Solid Recovered Fuel (SRF) by reducing the moisture content in the drum dryer.

rotary dryer design & working principle

rotary dryer design & working principle

For evaporating moisture from concentrates or other products from plant operations, Rotary Dryers are designed and constructed for high efficiency and economy in fuel consumption.Whenever possible to apply heat direct to the material to be dried, Rotary Dryers of the Direct Heating Design are used. If it is not possible to apply heat direct to the material to be dried, Rotary Dryers of the Indirect Heating Design can be furnished so that the heated gases will not come in direct contact with the material.

Rotary Dryer is a simple, inexpensive unit for reducing the moisture content of flotation concentrates, as well as chemical and industrial products. Frequently the saving of shipping weight so effected will pay for the dryer in a few months. Difficulties from freezing while in transit are also eliminated. Many industrial projects are now using Dryers for control and production purposes on many materials.

Three main types of Rotary Dryers can be supplied. The direct heat unit is used when it is permissible for the drying gases to come in direct contact with the material being dried. Partition plates increase the heating surface. Drying may be by hot air or exhaust gases from other operations. If this drying gas has a deleterious effect on the product, then an indirect type of dryer can be supplied. A further derivation is the Tedrow Steam Dryer.

Of the different types of dryers that there are the most common is the ROTARY DRUM DRYER/Kiln, This type of drier is common not only in the mining industry but you will find them in fertilizer plants, Cement plants, and peat hogs to name but a few.

The theories behind these machines are very simple, heat an air space up, and then tumble the material to be dried through this space until it is dried. All though it sounds simple there are problems that have to be solved before the required results are met. But first, so you know what we are talking about lets go through the design of a drier.

First is the KILN, this provides the heat, The BURNER is inside this portion. The fuel for the burner is usually diesel although heavy crude oil could be used in some cases. To be able to generate enough heat to dry the concentrate air must be added by way of a BLOWER. In front of the kiln is the point that the wet concentrate enters the drier. It is put into the revolving SHELL. The shell is on a slight incline. As the Concentrate is tumbled through the hot air mass of the drier it travels down this incline to the exit of the drier.

At this exit point the concentrate is either deposited straight into a storage area or taken to the storage area by a conveyor. It is also at this point that there is an EXHAUST HOOD. This provides a controlled escape passage for the fumes and water vapor that is generated by the concentrate drying. This is a very important function and the operator will have to be sure that it is open at all times. If it should become blocked the water vapor will not be able to escape. The concentrate will become wet and sticky which will result in the discharge plugging. The wet sticky concentrate will also lower efficiency level of the drier for an extended period of time. This happens because inside the drier shell are what are termed FLIGHTS these are flat pieces of metal that are bolted onto the shell.

They are there to lift the concentrate up to the top of the shells rotation and drop the concentrate through the hot air. If the water vapor isnt taken away, the concentrate becomes sticky from reabsorbing the water. This sticky concentrate will fill the spaces between the flights.

The concentrate will not be lifted and dropped through the hot air. This results in a long term condition of poor performance even after the initial problem has been cured. These flights will remain buried in concentrate. This removal of the water vapor is one of the functions of the blower. It assists the natural process of air movement as the hot air mass expands. To prevent the buildup of concentrate on the flights there are often CHAINS attached to them. As the drier revolves the chains slap the flights preventing concentrate from building up on dryers walls.

The drier shell is rotated separately from the stationary kiln section. To achieve the rotation a BULL GEAR is attached around the shell section. There are also two flat rings attached to the shell. These provide surfaces for support rollers to roll on. There is another problem that the inclined shell has, the incline causes the shell to want to slide in the direction of the incline. To prevent this additional rollers are attached to the last set of rollers.

Rotary dryers are widely used in food, feed, chemical, pharmaceutical, mining and other industries. The working process of the equipment is as follows: After the dewatered wet material is added to the dryer, the material is evenly dispersed in the dryer and fully contact with hot air under the rotation of the plate reader which is evenly distributed in the drum, accelerating the drying heat transfer and quality transfer. During the drying process, the material is discharged from the finished product in another section of the dryer by a star-shaped discharge valve, under the action of a slanting plate and hot air. This machine is suitable for drying all kinds of dregs with less than 85% water content, such as beer dregs, bean dregs, spray pulp corn husk, coal mud, fruit dregs, etc.

It has good effect for opening up feed resources, reducing feeding costs and environmental pollution for 10 years, the main export products of our drum dryer are vibration drying equipment, vacuum drying equipment, small and medium grain, food and agricultural, forestry and special products drying equipment, the annual export volume is more than a few hundred units, the main export areas are Southeast Asia and other developing countries, and has opened the door of the European and American markets.

The heat source for the rotary dryer comes from the combustion unit and uses a down-flow heating method. Therefore, the material that needs to be dried, from the feed box, feed slips into the cylinder, i.e., pushed back by the spiral plate. As the dryer is tilted, the material flows to the back end under the effect of gravity and rotation on the one hand, on the other hand, the material is repeatedly copied up, brought to the upper end and then continuously spread down, so that the material forms a uniform curtain in the tube, fully with the tube of the thermal airflow for heat exchange, due to the repeated spread of the material, the moisture contained in the drying, thus achieving the purpose of drying.

The operation opens the door and rotates the dewatered material evenly in the rotor, then closes and locks the door tightly. Depending on the type of material, select the appropriate time and adjust the timing device to the desired time. Press the start button to start the fan, and the direction of rotation of the rotor can be selected from unidirectional or bidirectional rotation according to the users needs. Simply rotate the computer board switch to one way or both ways and the machine will perform one way or both ways as required. (Forward 25 seconds, stop for 5 seconds, reverse 25 seconds) often watch the internal fabric turning from the observation window, if you find an unexpected situation should promptly cut off the power and check the fault. The machine will stop automatically when it reaches the specified time, and the operator must be asked to open the door to check the drying of the internal fabric.

The dryer is mainly used to dry materials of certain humidity or particle size in ore dressing, building materials, metallurgy, chemical and other departments. The dryer is widely used in tea, Chinese herbs, corn, vegetables, food, chicken manure, slag, towel quilt, sawdust, coal sludge, desulfurization gypsum, compound fertilizer, honeysuckle, straw briquetting fuel, charcoal machinery, wood chip pellet fuel, sawdust briquetting, agricultural engineering and other industries.

The main types of dryers are: rotary dryer, three-way dryer, three-tube dryer, intermittent dryer, direct heat dryer, clothes dump dryer, powder dryer, stone professional dryer, new dryer, second-hand dryer, industrial dryer, tea dryer, Chinese herb dryer, corn dryer, vegetable dehydration dryer, food dryer, chicken manure dryer, drum dryer, rotary dryer, stone dryer, rotary dryer, solder dryer, automatic dryer, oil dryer, electric heating dryer, energy-saving dryer, clothing dryer, towel quilt dryer, computer intelligent dryer, steam dryer, gas dryer, coal sludge dryer, slag dryer, sludge dryer, quartz sand dryer, sand dryer, fly ash dryer, desulfurization plaster dryer, sawdust dryer, tunnel dryer, dehydration dryer, compound fertilizer dryer, honeysuckle dryer, wine tank dryer.

The power generated by electric power, diesel power, wind power, flammable material power, etc. is heated by ambient air and transported to the perimeter of the pass-through, which then reaches the appropriate temperature for dehumidification treatment. The process is as follows: the wet material is fed to the hopper by a belt conveyor or bucket elevator, and then through the hoppers feeder into the feed end through the feed pipe. The slope of the feeding pipe should be greater than the natural inclination of the material so that the material flows smoothly into the dryer.

A dryer cylinder is a rotating cylinder that is slightly inclined to the horizontal line. The material is added from the higher end, and the heat carrier enters from the lower end, and contacts the material in a counterflow, there are also heat carriers and material together and flow into the cylinder. As the cylinder rotates the material runs by gravity to the lower end. In the process of moving forward in the cylinder, the wet material is directly or indirectly given heat by the heat carrier, so that the wet material can be dried, and then sent out at the discharge end through the belt machine or screw conveyor.

In the cylinder body wall is equipped with a copy plate, its role is to copy the material up and down, so that the material and airflow contact surface increases, in order to improve the drying rate and promote the material forward. Heat carriers are generally classified as hot air, flue gas, etc. After the heat carrier has passed through the dryer, a cyclone dust collector is usually required to trap the material in the gas. To further reduce the amount of dust in the exhaust gas, it should also be released after a bag filter or wet filter

The drying strength is high, and due to the high dispersion of the material in the airflow, the entire surface of the particles is actively the effective area for drying. Short drying time. The airflow dryer is simple in construction, has a small footprint and is easy to build and maintain. High handling capacity and high thermal efficiency. When drying non-bonded water, the thermal efficiency is up to 60%. The dryer achieves zero horizontal thrust, which greatly reduces the wear of the retaining wheel, and the barrel runs smoothly and reliably; the dryer adopts spherical pallet device, which makes the fit of the pallet and the roller always in linear contact, thus greatly reducing the wear and power loss.

When it comes to drying solid bulk materials, Baker-Rullman direct heat rotary drum dryer machines have been chosen for their rugged build, ultimate reliability and excellent ROI. Our direct heat rotary drum dryer machines rely on contact between the material and process gas to dehydrate a very broad variety of materials. The unique triple-pass dryer design is recognized for its efficiency, and ability to produce a consistent product output over extended operational periods. In the rotary drum dryer process, combusted gases mix with clean, heated air. The wet bulk material is propelled through the system via a hot gas air stream. The material is continuously lifted by the cylinder flights and showered through the concurrent stream of hot gases. The three full-length interlocked concentric cylinders rotate together to create the highest velocity possible in the inner-pass. As lighter particles quickly lose 60% of their moisture and move out of the cylinder, heavier/denser particles are retained until they also lose 60% of their moisture.

Rotary drum drying machine is widely used in organic fertilizer making plants. Its main function is drying different kinds of fertilizer raw materials or final pellets into appropriate moisture content. The rotating drum dryer equipment is a kind of necessary equipment for all kind of organic fertilizer and compound fertilizer producing factories. Using it, the post management of fertilizer products can be much easier and efficient.

Our rotary drum drying machine consists of a rotary drum, lifting plates, transmission, support device and sealing ring. The dryer mainly is a slightly sloping drum. The fertilizer materials are added from the higher end, the hot flue gas and the material flow into the drum at the same time. With the rotating of the drum, the organic fertilizer materials will move to the lower end of the rotary drum.

There are many lifting plates on the inner wall of the drum, which can pick up and sprinkle the fertilizer materials down, so that the contact area between the materials and the airflow is enlarged to improve the drying efficiency. At last, the dried product flows from the bottom outlet to the next procedure.

1. High degree of mechanization brings it larger working capacity. Meanwhile, it consumes lower fuel and when working, it doesnt need people to operate. That can greatly reduce your cost on hiring operators. 2. Our rotary drum drying machine has good characteristics of high temperature resistance, that ensures the high temperature hot air can dry fertilizer materials quickly. And this kind of drying machine is much more efficient than the traditional dryers.

3. The distribution and angle design of the lifting plates are very reasonable, making the performance of the machine more reliable and the operation more stable.

In wet granulation method fertilizer making line, the drying machine is very helpful to dry fertilizer granules. As we know, the raw materials granulated by wet granulation equipment always have high moisture. Before granulating, the materials always need to be dehydrated with about 30% moisture content by the solid-liquid separator machine. But this value is not suitable to the final granules. To bring granules more compact structure and improve their hardness, the drying machine is needed. After drying, its much easier to transport and store the fertilizer granules.

Fresh chicken manure always has high moisture content. Before making them into fertilizer, its very necessary to reduce the moisture content.
