Input Capacity 60 Tons Per Hour Sand Drying Machine

Rotary Dryer is special designed Inner 7 Chamber. and it is Concurrent Dryer.

02. Compact Structure, less space occupation.

03. Special 7 chambers inner design, when working, each part's weight of the dryer is balance. Less motor power needed.

04. The material will be flipped 7 times inside the dryer, and the flipping times is 2.3 times of the traditional drum dr Thus the material can be dispersed more sufficiently, and to be heated and dried by the hot air more sufficiently. As a result, the heat exchanging efficiency is higher, and its Riel consumption is lower.

05. The material falling height inside the dryer is reduced much, thus the material abrasion to the lifting plates and dryer drum is less.

06. Higher heat efficiency.

07. The material output moisture content can be controlled by adjusting tlie exhaust air temperature and the drying tin in the dryer.

08. In actual operation, its water evaporation intensity is more than 2 times of the traditional dryer, thus it has higher heat efficiency, and tlie operation cost is lower

10. It adopts Gear Drive with better stability .

Note: For Gear Drive type, can add lubrication oil between the roller and ring to reduce the friction, reduce the abrasion of roller and Ring.

For Roller Drive Type, it is use tlie friction between the Roller and Ring to transfer the power and make the dryer drum rotates, and it is not suitable to add lubrication oil between the Roller and Ring. Tlius the abrasion of the Roller and Ring is much more, and its lifetime is shorter.

10. The dryer totally has 4 sets of Roller ASSY, and each set of Roller ASSY consists of 2 rollers. It means that totally there are 8 supporting point for the dryer macliine. and the loading weight on each roller is only half of the loading weiglit on each roller of the traditional Triple Drum Dryer, thus it increases tlie nurning stability of the dryer machine.

Air drying system in compressor system Drying equipment

Drying equipment is also called dryers and dryers. A device used for drying operations in which the wet component (generally water or other volatile liquid components) of a material is vaporized and escapes by heating to obtain a solid material with a specified moisture content. The purpose of drying is for material use or further processing needs. If wood is IN the drying before making wood model, wood can prevent product deformation, ceramic billet before calcination can prevent finished product cracking. In addition, the dried material is also easy to transport and storage, such as drying the harvested grain to a certain wet content below, to prevent mildew. Because natural drying is far from meeting the needs of production development, various mechanized dryers are more and more widely used.

air drying system in compressor system How it works:

The drying process needs to consume a lot of heat energy. In order to save energy, some materials with high wet content, suspensions or solutions containing solid substances are generally first dehydrated by machinery or heated to evaporate, and then dried in the dryer to get dry solids.

In the drying process, it is necessary to complete the transfer of heat and mass (wet fraction) at the same time, to ensure that the wet fraction steam partial pressure (concentration) on the material surface is higher than the wet fraction steam partial pressure in the external space, and to ensure that the heat source temperature is higher than the material temperature.

Heat is transferred from high temperature heat source to wet material in various ways, so that the material surface wet vaporization and escape to the external space, so that the difference in wet content between the material surface and the interior. The internal wet component diffuses to the surface and vaporizes, so that the wet content of the material is constantly reduced and the overall drying of the material is gradually completed.

The drying rate of the material depends on the surface vaporization rate and the diffusion rate of the internal wet fraction. Generally, the drying rate in the early drying stage is controlled by the surface vaporization rate. Then, as long as the external conditions of drying are unchanged, the drying rate and surface temperature of the material remain stable, this stage is called constant speed drying stage; When the wet content of the material decreases to a certain degree, the diffusion rate of the internal wet component to the surface decreases, and is less than the surface vaporization rate, the drying rate is mainly determined by the internal diffusion rate, and decreases with the decrease of the wet content. This stage is called the drying stage of decreasing speed. In addition, technological advances will also reverse the current export of domestic drying equipment. China's drying equipment has not formed an export scale, the export volume is less than 5% of the total, and mainly sold to Southeast Asia. However, according to the authoritative prediction, with the development of technology, the proportion of China's export drying equipment in the total production will increase from 5% to 10% in the next few years, and the export market will also expand from Southeast Asia to Europe and the United States. The large domestic drying equipment manufacturing and the international level there is a large gap between the situation is expected to improve.

air drying system in compressor system Equipment Classification:

Equipment used to perform drying operations. There are many types. According to the operating pressure, it can be divided into normal pressure and decompression (decompression dryer is also known as vacuum dryer). According to the operation method, it can be divided into intermittent and continuous. According to the drying medium can be divided into air, flue gas or other drying media. According to the mode of movement (material movement and dry medium flow), it can be divided into parallel flow, countercurrent and cross-flow.

By operating pressure:

According to the operating pressure, the dryer can be divided into two categories, atmospheric dryer and vacuum dryer, the operation can reduce the moisture of the space in the vacuum steam partial pressure and speed up drying process, and can reduce moisture boiling point and material drying temperature, steam is not easy to leak, so the vacuum dryer is suitable for drying heat sensitive, easy oxidation, explosive and toxic materials, and moisture vapor recovery.
