During their practical applications, because the structure is more complicated, multi-cylinder dryers are difficult to maintain. Also, its materials are easily clogged when the moisture is high. Therefore, single-cylinder dryers are the most popular type in the market.

And according to the heat transfer mode between the drying medium and the wet material, the rotary dryer can be also divided into two different types: direct-heat rotary drum dryer and indirect-heat rotary drum dryer.

The heating medium of the indirect-heat rotary drum dryer is not contacted with the material directly. All the heat required is transferred to the material through the heat transfer wall. While the material directly contacts with the internal heating medium, and mainly dried by convective heat transfer. Thus, the latter is used more widely.

The material granularity is generally not larger than 50 mm. And with the strong adaptability to materials, it can process varieties of materials. Besides, because of its simple and reliable structure, the rotary dryer is the most popular equipment for drying.

It can not only dry magnetic, heavy and floating concentrates of metal and non-metallic ore, but also dry clay in the cement industry and slime in the coal industry. Besides, it can be used for drying powder and granular with special requirements, such as various crystals, light calcium carbonate, activated clay, magnetic powder, graphite, etc.

2. In the middle of the drum, there are lifting plates welded. By changing the angle of the lifting plate, the height of the lifting material can be reduced to avoid the deformation of the material.

The material is sent to the hopper by the belt conveyor or bucket elevator and then enters the drum through the feeding pipe of the hopper. Because of the inclination angle of 5 to the horizontal, the material can naturally flow into the drum.

To achieve the perfect drying effect and reduce investment costs, besides paying attention to equipment installation and operation, selecting a high-quality equipment manufacturer at the very beginning is a top priority.

Being a mining machinery manufacturer with more than 37 years of experience, Fote Heavy Machinery has been persisting in exploring and designing higher-quality mining equipment with more advanced technology.

FTM rotary dryer designed under the aim of customers' benefits is not only in high-mechanized, strong-capacity, but also runs smoothly and continuously. And its failure rate is lower than any others.

Simple operation with new internal structure, FTM rotary dryer strengthens the cleaning and heat conduction of the dispersed materials and solves the problem of the sticking phenomenon on the inner wall. So, it has stronger adaptability to the moisture and viscosity of the materials

Maximize the use of hot air: Choosing the LX multi-combination lifting plate to make the material enter the drying drum like rain curtain, which increases the contact surface between the material and the hot air.

Increase contact surface with hot air: The hot air in high velocity makes the material well dispersed in the drum. The entire surface of the material can be used as an effective area for drying, which can improve the drying efficiency largely.

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.

The Materials to be dried enter into the dry zone of special combination plates are thrown by drying plate for vertical movement because of angle difference and rotational motion of the drying plate. After making heat exchange with the materials, the high-temperature furnace gas discharged into the cylinder evaporates water and drys the material, it can prevent the material from sticking on the inside of the cylinder. It is a part of the pellet mill plant.

Wet feed material is made to shower continuously in a cascade manner in a stream of hot air, when moisture gets transferred to the air, rendering the product progressively dry as it travels the length of the dryers cylinder provided with suitable lifters. The humid air is exhausted via a dust collection system to trap any fines escaping with the exhaust air.

Hot air at desired temperature and flow rate is made to flow through the tumbling bed of wet feed. The wet material gets progressively dried to the final level of desired moisture and exits at the discharge end. The humid air carrying moisture transferred from the drying material is exhausted via a dust separator.

Widely used equipment for granular and free flowing material. Rotation of dryer promotes intimate mixing and fresh surfaces are constantly exposed to the incoming hot gases resulting in uniform drying. Dimension : 1433 x 852 x 1347mm Max Temperature : 1000-2000 Degree Celcius Surface treatment : Polished

The wet feed which has free flowing form is made to work over the rotating bundle of heated tubes. Due to radiation and conduction effects, the moisture is evaporated and the product becomes progressively dry as it travels across the dryer and reaches final moisture level at the discharge point. Due to effective turbulence the solids are dried uniformly. Diameter : 0.3-5 m Operating temperatures : 600 degree Capacity : 100kg/hr to Surface Treatment : Polished
