Rotary dryer manufacturing has grown and many people are now aware of it. Getting a rotary dryer may not be an easy task. The dryer's purpose is to ensure that materials are able to dry inside the cylinder. This is done in a way that the materials are able to form a curtain hence increasing the area and heat which in return dry the materials. The good thing about a rotary dryer is that the process is usually continuous. The dryer is cylindrical and has two ends through which damp materials enter and dry materials come out on the other end. They can also be used to dry a wide array of materials which include building materials like sand. It is also easy to operate so the users are able to adjust pretty quickly and the end result is the same. Below are the things you need to consider when choosing a rotary dryer.
First, you need to consider if you want direct heat or indirect heat. Direct heat dryers have a co-current flow of heat whereby there is dry air being passed through that drum. This may not be ideal for consumer products since it may come to contact with mixed gases that are not healthy. The indirect heat does not allow for these gases to come in any contact with the products which can affect them. Therefore, you have to look at the uses of the dryer and ensure that there will be no harm to the materials.
Secondly, you could choose a customized one. This is designed to suit a specific material so as to be able to dry it in the best way. Not all material requires the same drying and this may affect the success rate of drying other products. There are some things that get impact the decision like the moisture content and the bulk density. This will affect the design of the rotary dryer since at the end of the day it has to suit your product. It should be in a position to perform well since it is designed to serve a specific purpose and material.
Lastly, you need to check on the operational surroundings. The region that you are in plays a huge role in the performance of the dryer. The atmosphere, humidity may have a very huge impact on how the dryer performs. It is crucial that you take this into consideration when choosing one. An increase in the elevation will decrease the oxygen and this means that the air becomes less dense. If there is a higher elevation, then the size of the fan needs to be slightly bigger so as to compensate. This affects the overall performance and if you are looking forward to being efficient you have to ensure that you get the right dryer for your materials. You should take all these aspects into consideration so as to get the best dryer. These are the factors that you need to consider when choosing a rotary dryer.
