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.

There are many different reasons for why a company might get rid of industrial machinery. Usually it is during an expansion or shrinking phase, where some of their machines can become unnecessary, long before they are actually technically obsolete.

There are generally other types of requirements for machines used in industry than those used for private businesses. It is always guaranteed that machines used in industry have a permanent level of high quality and robustness, are easy to maintain and have a reliable supply of spare parts. This means that even used industrial equipment for start-ups are a useful investment to ensure that the required productivity is met.

Wood is an extraordinary material, that provides a wealth of technical characteristics that no other material can. It is light, stable, affordable and available in various forms. This natural material is ideal for many different uses. There are a number of different woodworking machines available for efficiently processing wood.

Metal is the most used material when manufacturing industrial machinery and devices. Metalworking can take place in a variety of different ways. Casting machines and technology is used to form and shape metals. They are either poured into a pre-product or directly formed into the end shape, directly out of the mould. Extruder and die casting machines are used for this process.

After the metal is formed, it can be further processed. Rolling machines, metal-presses and welding machines are most commonly used for this. Metal is prepared for industrial machinery using separation processes by being rolled into sheets and then wrapped onto reels. Punching machines and machine tools are used to separate sheet metal. Cutting machines are used to process individual sheet metal. These are available in the form of flame cutters, laser cutters or water cutters.

All these machines are available used, in a variety of different levels of automation. This means that it is easy to find used industrial equipment that is best suited for the desired operation or task. Training facilities and small manufacturers usually prefer compact industrial machines that are primarily manually operated. Large machines with high output rates are best for producers of series components. The used market provides a variety of used industrial equipment ranging from completely manual to those that are fully automatic.

These machines are also supplemented by a number of different auxiliary materials, conveyor belts, turning stations, packaging machines or industrial robots to help increase the productivity of a facility. Even these machines are available in large numbers and in great condition on the used machinery market.

There are two types of coulometric reagents: the anolyte (generating solution),which is placed in the anode chamber of the electrolysis cell, and the catholyte (counter electrolyte), which is placed in the cathode chamber. There are also special anolyte for use with ketones, lower carboxylic acids and silicone oils. AQUAMICRON can be used in coulometric moisture measurement systems sold by various companies, and it has a worldwide reputation for excellent performance.
