After we designed the best dryer available, we also made sure that it was safe (OSHA approved); efficient (open end design for easy loading); economical (low horsepower, low CFM requirements); dependable (laser aligned to minimize wear).

You see, the DIDION Rotary Dryer is totally reliable technology for drying a full range (and sizes) of materials. Uniquely designed to provide optimum product exposure to incoming heated air, it also maintains temperature uniformity with a variable Jet burner.

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.

Hills Clotheslines began in 1945 when Lancelot (Lance) Leonard Hill returned home from the Second World War. He found his wife Sherry struggling to hang the laundry between the overgrown trees in their back yard, so he took some old pipe, a welder and an innovative idea and created what was to become a world famous Australian Icon. The Hills Hoist was born. Word of Lance's invention quickly spread until one day, on a tram on his way to work, Lance overheard two women talking about wanting a rotary clothes hoist they had seen in a friend's yard. Lance got off the tram at the next stop, walked home and told Sherry that he was going into business to make the Hoist. Hills Industries was born. Since 1946, Hills Clotheslines have been known throughout the world for quality, durability and sustainability.

We discontinued selling Hill's Clotheslines in 2017 shortly after they were acquired as everything they were well known for significantly declined when they outsourced manufacturing to China in the mid-2000's throwing sustainability and durability out the window in hopes of profitability while chasing their new high-tech ventures. As an Australian publicly traded company, the stock has long traded for pennies, so it was not long after they sought cheap Chinese labor that they were desperate to rid themselves of the Hill's Clotheslines products, less than 10 years. After a failed partnership with Woolworths in 2014, they eventually sold the iconic Australian Hills Clotheslines to a publicly traded US company.

To learn more, visit our Clothesline History blog post. Buyer beware, don't let companies selling Hill's Clotheslines fool you into thinking the products have anything to do with Australia as most hide the fact the products are made by slaves in China, using toxic materials. One of the reasons we discontinued selling Hill's Clotheslines is because of the many negative reviews we were receiving from customers that have been using the products for decades and noticed a major decline in quality. As one customer told us, the 10-Year Warranty is a complete joke as you'll be lucky if the products last a couple years, at most. As their craftsmanship, or lack thereof, spiraled downhill, I don't think they reviewed their product warranties to reflect the quality of the products since they are cheaply made in China.

We are happy to be partnered with Austral Clotheslines, two letters short of Australia, as their products are reminiscent of the original Hill's Clotheslines range, made in Australia to the highest quality standards ensuring strong and sturdy products. Austral is the ONLY clothesline company still manufacturing a full range of clotheslines in Australia and their products are backed by a 10-Year warranty.
