Wood chip dryer

Wood chip dryer is called sawdust dryer is the most effective processing equipment for recycling high-humid materials such as sawdust, sawdust, chips, veneer, distiller's grains, pomace, wood chip dryer professional design process concept, excellent practice drying Technology, fast drying speed, large amount of processing, and remarkable energy saving effect are favored by customers at home and abroad and have always been in the leading position in the industry.

In the process of using the wood chip dryer, in general, the wood chips enter the drum of the wood chip dryer from the feed port, and the blow pipe and the rotary cylinder work together to boil and fluidize in the cylinder, and the hot air is in full contact with the material. Drying operation, air-flow wood-drying machine, so-called air-drying refers to the use of powdery wet sawdust, which is continuously added to the drying pipe by a screw conveyor. During the conveyance and dispersion of high-speed hot air flow, the wood chip dryer makes wet materials. The evaporation of moisture in the process to obtain a powdery or granular dry product, complete the drying.

In the process of drying, air has a certain influence on the floatability of minerals in the wood chip dryer. In addition to oxygen, nitrogen, and inert gas in the air, there is carbonic acid gas and water, in which the role of oxygen is The initial hydrophobicity of the sulphide ore is advantageous, but if the effect is too long, it will cause the mineral surface of the dryer to become hydrophilic, but when the gas adsorption conditions are appropriate, it will cause the hydrophobicity of the mineral surface of the dryer. Even without flotation agent can float.

When the sawdust dryer breaks up and exposes the fresh surface, it will be hydrophilized when it encounters water. This is manifested as hydrophilic. However, when the gas adsorbs to the mineral surface, the effect of hydration can be weakened, resulting in the initial hydrophobicity of the new surface. The interaction between gas and mineral surface is selective. Oxygen is the most important component of the mineral surface. However, it should be stated that the main role of air in the flotation process is to cause a large number of tiny bubbles to carry the floated material up. The above shows that the air has a certain influence on the materials dried by the dryer.
