Rotary dryer(Drying Machine) is used for drying materials with a certain humidity or granularity in milling of ores, building materials, metallurgy and chemical industry. Gyro drying machinery has a strong adaptability of materials and it can dry various materials. The operation is very simple and liable. For this reason, it is used widely.
Rotary Dryer Working principle
Materials are sent to hopper of rotary dryer by belt conveyor or bucket elevator.The barrel is installed with slope to horizontal line. Materials enter the barrel from the higher side, and hot air enters the barrel from the lower side, materials and hot air mix together. Materials go to the lower side by gravity when the barrel rotates. Lifters on the inner side of barrel lift materials up and down to make materials and hot air mix completely. So drying efficiency is improved.
Type of Rotary Dryer
Fodamon specializes in the production of large dryers, industrial dryers, etc., which are also called drum dryers, rotary dryers, etc. According to the different drying materials, they are also called cement dryers, slime dryers, sludge dryers, animal dung, bean dregs, palm dregs, desulfurization gypsum dryers, sand dryers, fly ash dryers, lignite dryers, etc. Dry mortar dryer and so on.
According to the different processing materials, it can be divided into talc dryer, kaolin dryer, lignite dryer, sludge dryer, sand dryer, river sand dryer, slag dryer, slime dryer, fly ash dryer, clay dryer, gypsum dryer, concentrate dryer, desulfurization dryer, etc.
