With the development of mining machinery industry, there are many kinds of mining machines in the market, such as crushers, cone crusher, jaw crusher and so on. Oh, saying the jaw crushers, do you know what surprise can the rotery dryer bring back? If you have not ever heard of it, today our expert of HXJQ will talk something about it. I think you can read this article with your a little time.
Rotary dryer can also be referred to as rotary drum cooler, handling by taking it into direct contact with a heated gas. The dryer is created from a large, rotating cylindrical tube. and then we will see the working principle of the rotary dryer. They are as following:
Materials being dried enters the dryer, and as the dryer rotates, the fabric is lifted up by way of a group of internal fins lining the inner wall with the dryer. In the event the material gets high sufficient to roll keep your distance the fins, it falls down again on the bottom from the dryer, passing by means of the recent gas stream as it falls. This gas stream may either be on your journey to the discharge end in the feed end (known as co-current flow), or toward the feed end in the discharge end (identified as counter-current flow). The gas stream could be produced from a mixture of air and combustion gases from the burner, in that case the dryer is referred to as a primary heated dryer. Alternatively, the gas stream might incorporate air or yet another (at times inert) gas which is preheated. In the event the gas stream is preheated by some means where burner combustion
