The construction of rotary dryers features a vessel (drum) that rotates and tumbles materials inside whilst the air flows through causing evaporation of the moisture. Additionally, vessels are equipped with lifters linked to the shell of the vessel. These lifters constantly shuffle and tumble the material allowing for better drying.

Depending on the properties of your product, it is possible to set the duration of drying (retention of energy) and optimal temperature. This will allow you to obtain the material to required condition. The majority of standard models can handle multiple varieties of drying processes. However, we also manufacture rotary evaporator which will match your purposes even better than standard equipment. You will find a plethora of things that we consider when making a custom rotary dryer.

Construction of Rotary Dryers.

Shell – The efficiency and longevity of the rotary dryer greatly depends on the material from the shell. It could be made from a rich selection of alloys with the most common choices being stainless-steel, Inconel, and carbon steel. Depending on the requirements of the production process, the size and shape in the shell could be altered. Shell thickness can also be adjusted in accordance with desired amounts of heat retention. Additionally, shell may have an alternative of sealing that enables to contain heat better. Remember that the shell is one of the most important areas of the development and deficient excellence of the shell will negatively affect both efficiency and longevity of your equipment.

Combustion chamber – This part of the construction accounts for generating hot gases through combustion of fuel. Chamber also sets the direction of air-flow which is often co-current or counter current. Depending on the requirements of your own production cycle, co-current or counter current dryers may be better. Chambers prevent materials from contacting with flame. There is plenty of options and modifications that can be placed on the combustion chamber. Another important feature is that combustion chambers may be used together with a multitude of burners. A combustion chamber defines the efficiency of both energy consumption and heat transferring. Because of this a subnormal part will decrease the efficiency of the equipment.

Burner – Burner generates heat by, since the name suggests, burning fuel. The standard of the burner will change the efficiency of fuel usage. You are able to modify a burner to work alongside a number of fuels like propane, gas, solid fuels, etc. Burner should be chosen depending on the requirements of your production process.

Material Feed – The part of the construction where the material enters the vessel. It is almost always called feed chute. This portion of the construction needs to be made of robust materials in order to prevent wearing. At the same time, accretion risks also need to be considered.

Air Seal – The environment seal prevents material from falling right out of the vessel from the breech in between the drum and combustion chamber. You need to pick the right kind of the seal based on the type of the material that you work with.

Drive Assembly – To be able to work, rotary dryers need engines. Drive assembly is actually a mechanism that combines various parts of the energy block. The setup could be different according to your specific requirements. Amongst available options: pin and gear, chain drives, friction, and direct drive. Different setups serve different purposes. For instance, chain/sprocket system is perfect for small application where 75 horsepower is ample. On the contrary, gear/pinion method is more suitable for heavy-duty purposes that you need more power. In order to control power output, your drive assembly can be designed with a reducer. Small drums could be also powered with a friction drive system that works over a shaft mounter engine and reducer. The direct option is usually selected for bigger applications, but rarely for those that require a lot more than 70 horsepower. Direct option, because the name suggests, is probably the best setups with both an engine and reducer connected right to the shaft.

Riding Ring – This is a very important part for your shell. A little pressure-consuming add-on drastically reduces mechanical wear of the equipment.

Thrust Rollers – Supportive mechanisms for your riding ring that allow you to move it or fixate its position.

Trunnion Wheels – This part of the construction takes off of the shell a lot of pressure. Trunnion wheels ensure that the rotating motion is smooth and this the drum never skews its rotation axis. This part is normally build cheap as it is hard to prevent mechanical wear. Trunnion wheels are really easy to replace.

Lifters/Flights – Depending on the kind of the fabric that you simply will work with, lifters might or might not be necessary. However, flights are generally utilized to raise the efficiency in the industrial drying process. Flights get the fabric and drop it down so the hot air goes right through the curtain formed by the falling material. Lifters can be tjihbx depending on the type of the content.

Discharger – The rotary evaporator will be the area of the construction that serves as the outlet in the dryer. This part is generally linked to the cooler that lowers the temperature of the material for more processing.

Discharge Breech – To ensure the merchandise and off-gases to leave the drum and proceed, they need to browse through the discharge breech. This part of the construction allows worked gases to become released as well as the product to leave the drum and be moved to next production stages. Undesired components of exhaust gases are easy to remove after in order to prevent environmental damage.
