Features
The three-return dryer is composed of an inner cylinder, a middle cylinder and an outer cylinder to form a self-insulation circulation structure, so this new type of dryer is also called a three-cylinder dryer. The combined three-cylinder dryer has the characteristics of compact structure, small footprint, low energy consumption, high thermal efficiency, good material drying effect and easy to achieve automatic control. It is mainly used for drying granular materials within a certain humidity range, such as yellow sand used in dry mortar industry and various specifications sand used in casting industry. Blast furnace slag used in building materials and cement industry. According to the moisture requirements of materials after drying in different industries, the moisture content of materials after drying can reach 1-0.5% or less, which is the ideal choice for various drying projects.
Working Rrinciple:
The materials to be dried by the dryer slip into the cylinder from the feed box and feed, and are then pushed to the back end by the spiral sheet. Due to the inclined placement of the dryer, the material on the one hand in the gravity and rotation of the downward end, on the other hand, the material is repeatedly copied by the sheet, brought to the top and then continuously lifted down, so that the material in the cylinder formed a uniform curtain, fully with the hot gas flow in the cylinder heat exchange, due to the repeated lifting of the material, the moisture contained in the gradually dried, so as to achieve the purpose of drying.Main structure: The main frame part, eccentric shaft rotation part, crushing chamber working part, safety device, discharge port adjustment device and other parts.
Product Advantages:
1. Small footprint, low installation cost
The equipment has a compact structure and small footprint, which is one half of the footprint of the same output single cylinder dryer, and the civil construction investment is reduced by about 60%, and the installation is convenient.
2.Good wear resistance, strong and durable
The whole machine is made of wear-resistant steel plate, which is 3-4 times wear-resistant than ordinary steel plate, low maintenance rate and long service life.
3. Reduce production processes and save costs
The discharge temperature is basically lower than 60 degrees, and it can be directly fed into the warehouse without entering the cooling shed for cooling, saving the production process and production costs.
4. Advanced technology, energy saving and environmental protection
The use of new energy-saving technology - Mosaic structure, and special thermal design concept, eliminate wind tunnel heat loss, increase heat exchange area and unit volume evaporation intensity, energy saving effect is good, is to replace the traditional drying equipment of environmental protection and energy saving products.
