Hongxing rotary dyer has the most advanced design

During ore beneficiation, a dryer machine should always be available. Rotary dryer, also called drum dryer, is such a machine which is in need. It is a kind of device for heating and drying the material. During ore beneficiation, a dryer machine should always be available. The rotary dryer, manufactured by our company, is hot sale. The rotary dryer, mainly used in mine beneficiation, building material, metallurgy, chemical industry and other sectors, is drys material with a certain humidity and size.

In rotary dryer, the pneumatic valve fitted on the burner makes use of fluid mechanical property of specially designed intake vent, which forms physical barrier to combustion products backflowing to the feed port. The main advantage of pneumatic structure is that it omits the valve and moving parts. Consequently, mechanical failure and invalidation are eliminated. This is of vital importance to heavy pulse burner.

Although rotary dryer is widely used in almost all industrial sectors, it still needs innovation in technology. As is known to us all, many factors propel the innovation of rotary dryer, such as energy consumption, product quality, environmental impact, the overall cost for thermal dehydration, etc. Experts in drying equipment will give you a detailed introduction to perfection measures and performance display of pneumatic valve.

The most common design concept is to produce low resistance to inflowing materials and high resistance to outflowing materials. The inlet structure is commonly known as fluid diode. Certainly, the fluid diode in rotary dryer can”t be compared with mechanical check valve in performance due to the reason that it cannot restrain backflow.

When the material gets high enough to roll back off the fins, it falls back down to the bottom of the dryer, passing through the hot gas stream as it falls. This gas stream can either be moving toward the discharge end from the feed end (known as co-current flow), or toward the feed end from the discharge end (known as counter-current flow). The gas stream can be made up of a mixture of air and combustion gases from a burner, in which case the dryer is called a direct heated dryer. Alternatively, the gas stream may consist of air or another (sometimes inert) gas that is preheated. When the gas stream is preheated by some means where burner combustion gases do not enter the dryer, the dryer is known as an indirect-heated type. Often, indirect heat drier is used
