Chinese dryers market current situation as well as analysising the current demands of the United Stations, the common dryer machine of the domestic market as well as main dryer machine in the international market are mainly made in China, which suggests that the history where China exported dryer machine from abroad ended.
Roller dryer is used for drying materials with humidity or granularity in the industries of mineral dressing, building material, metallurgy and chemical. Rotary dryer can be used for drying many kinds of materials and with convenient and reliable operation. The rotary drying machine is mainly used in ore selecting, building materials, metallurgy and chemicals to dry the materials with certain moisture and size. The dryer machine has a strong adaptability which can dry many kinds of materials with a simple operation method and security trait, so it is widely used.
For different drum dryers, how to dry the flue gas quickly and uniformly is related to the flow rate of the hot air in the cylinder. In order to dry the materials uniformly, Henan Hongxing Mining Machinery Co., Ltd will conduct this drying process according to the following solutions:
1. By adding the contact area and contact time between materials and hot air in the cylinder to the unit length, by reforming feed plate to improve the dispersity of the materials in the cross section of cylinder, also can achieve this goal by adding the length of cylinder.
2. Improving the flow rate of the hot air, can directly improve the heat transfer coefficient and mass transfer coefficient, also improve the drying efficiency, besides, can exchange hot air timely, which is conducive to the diffusion process. However, improving the flow rat of hot air, can also reduce the staying time of hot air in the cylinder, which lead to less time for drying the gas desulfurization gypsum, affect the thermal efficiency, resulting in wasted heat.
