rotary dryers

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.

contact drum dryer

contact drum dryer

The ANDRITZ Gouda drum dryer with its continuous indirect drying method, allows short heat retention times while evaporating all the liquid within a single rotation of the drum. It not only virtually eliminates the risk of damaging the product but also enables the product to keep its unique properties like taste, smell, texture, etc.

The drum body of the drum dryer is heated on the inside by steam. A special composition of cast iron gives the drier a combination of favourable properties: accurate shape retention even at high steam pressure and temperature, and excellent "scraping properties" for the scraping knife.

Steam heating gives a uniform temperature distribution over the drum surface and this results in a consistent product quality. The steam condenses on the inside of the drying drum. The condensate is continuously removed from the drum, so that the largest possible surface area remains available on the inside of the drum for condensation of the steam. The steam system is a closed system, which means that the product cannot come into contact with the steam or condensate.

Depending on the design of the drum dryer, the product is applied continuously as a thin film on the underside or top of the main drum. As the drum rotates and is heated on the inside, the product dries on the outside of the drum surface. The short exposure to a high temperature reduces the risk of damage to the product. The water or solvent evaporates and leaves the process at the top. If necessary, the vapour can also be sucked off locally around the drum. The dried product film finally reaches the knife and is scraped off.

In a double drum dryer the product is fed into the sump between the two main drums (which always rotate in opposite directions). The small gap between the drums can be set accurately to obtain a desired film layer.

For the easy, hygienic drying of everything from baby / infant food to toxic chemicals, ANDRITZ Gouda is with you every step of the process. Product treatment before and after drying receives our equal attention. From kitchen preparation through to mill sifting and pneumatic transport, ANDRITZ Gouda offers you practical solutions as well as access to a wealth of informed research.

The well-thought-out construction of the knife holder guarantees an even pressure over the total length of the drum. The use of specific materials prevents vibrations as a result of scraping and guarantees uniform product removal. The pressure of the knife can be controlled simply and this is done outside the process area.

In the design, a clear distinction is made between the process section of the dryer and the mechanical parts. This, for instance, prevents the risk of contamination by lubricants (or contamination of the lubricants due to leakage of the product). It also improves the accessibility of parts for adjustment, inspection and maintenance.

asphalt dryer drum for sale in aimix machinery - longer service life

asphalt dryer drum for sale in aimix machinery - longer service life

Asphalt dryer drum is one of the most important component of asphalt plant drying and heating system. The main purpose is to remove the moisture from the cold aggregate and heat them, which can ensure bonding with the asphalt. As we all know, the moisture of cold aggregate should be controlled accurately. Otherwise, it may influence the finished product asphalt mixture. Therefore, it is essential to choose a best asphalt drum to improve working efficiency in the beginning of the whole process. Here is an elaborate introduction about asphalt drum dryer for sale. Hope it can help you a lot.

The structure of the asphalt drum mixer for drum mix plant is composed of a cylinder body, a feeding blade, a rolling ring, a supporting roller assembly, a thrust roller assembly, a driving device, an inlet and outlet cigarette box and a frame. The inner guide plate of the bitumen drum is divided into three sections according to the arrangement: the feeding section, the convection section (the curtain area) and the combustion section.

5. It has strong anti-overload capability and high reliability. Thus, the portable asphalt drum mixer runs smoothly with low vibration. Moreover, axial turbulence of the cylinder during operation is not more than 3mm.

6. The support roller and raceway are well matched, which can greatly reduce the wear and power consumption. Rollers service life is not less than 5000h and rolling rings life span is no less than 10000h.

The driving device rotates the inclined asphalt dryer drum. And the blades of different sections and different shapes in the inner side of drum scrape the aggregate and form a curtain. Then they fall and go forward at different positions so that the aggregate and the hot air flow are fully heat exchanged. In this way can the aggregate heat evenly.

After heating, the aggregate passes through the curtain area and enters the radiation area. The specially designed lifting board is attached to the inner side of the drum and rotates with the drum to avoid the disordered flow affecting the shape of the flame. At the same time, the radiant energy is used to maintain the aggregate temperature. In this way, the loss of incomplete combustion caused by the sticking of the fuel by the aggregate can be reduced.

In order to dry the cold aggregate and heat it to the required temperature (10~20 C higher than the asphalt heating temperature, generally 150~180 C, the asphalt type and label are different, so as heating temperature). In order to achieve this, a multi-stage lifting blade (lifting plate) is designed on the inner side of the asphalt dryer drum.

1. Clean the internal debris such as drying drum, furnace and pulverized coal machine. Check whether the inside lifting blades of the drying drum is fastened, and tear off the outer packaging of the drying drum;

5. Remove the universal joints; debug the motor one by one, arrange four people to observe the four motors separately; test the reverse rotation of the single machine; observe whether the positive and negative reversals are correct; whether the current is normal, and then install the universal joints after each motor is debugged normally.
