The main innovation in the following aspects: First, the use of the principles and methods of drying and efficient vertical dryer, as well as the use of mass balance and heat balance principle, retain simplified static external insulation, internal heat exchanger design and installation to be able to to adapt to the different nature of the material yield efficient heat exchange means were used cloth device attempts to prevent vibration dynamic vertical dryer, vibrating flow regulating device, rotary crushing device materials, inside and outside the annular inlet devices, completely solve the congestion problems; Second, the secondary hot air technology and structure; the third is adjustable structure, cement industry kiln dry process production lines produce large amounts of waste heat temperatures below 350 ℃ smoke, which utilize waste heat of the exhaust gas to reduce energy consumption, lower production costs have to shut important role. In the past, due to the rotary dryer itself is not defective in this part of the effective use of waste heat, and the dynamic and efficient vertical dryer adjustable structure passing through the preheating zone, drying with enlarged diameter, wind speed reduces evaporation larger space, while the residence time through different forms basin grate grate cone control of materials, maximize the efficiency of waste heat utilization; the fourth is in the drying zone detection system through preheating, drying with dry material with three regional water and air temperature line detection, automatic heating capacity of the material balance control system, wind, coal, and the system, the wind volume, distribution and secondary hot air heating capacity, material flow and cut system parameters such as residence time line adjusted to achieve Dynamic optimization of process parameters balance system, improve the utilization of thermal energy systems. Through the above innovations, new drying equipment will certainly be more responsive to the actual needs of the majority of enterprises. Such as gypsum dryer: building gypsum processing in different ways according to the heat transfer can be divided into two kinds of direct and indirect methods: 1, the indirect method (drying and calcining two step) drying and calcining the second step is based on the energy situation and the plant environmental requirements, the more easily prolapse prolapse free water and hard water crystals in both devices were set to make it more reasonable, but also facilitate the adjustment of product structure and quality control. The device can produce dry gypsum (cement retarder use), ultra-high-class product β gypsum. 2. Direct method (drying and calcining step) is to use a one-step drying and calcining gypsum calcination process unit high heat and mass transfer efficiency of the three drum drying technology research and development design. The process units can produce dry gypsum (cement retarder use), you can produce half water gypsum, gypsum production of dry air temperature only 120 ℃, can take advantage of low-temperature thermal power plant flue gas. Gypsum dryer technology, rotary drum dryer principle, mining dryer, industrial dryer.
