Rotary dryer introduction
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.
Structure of Rotary dryer
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.
Professional Maintenance Tip: The transmission system is the heart of a ball mill. To ensure long-term stable operation and reduce noise, we provide high-precision Girth Gear and Pinion sets specifically designed for heavy-duty grinding. Replacing worn gears with our matched 42CrMo sets can significantly extend your mill’s service life.

Rotary Dryer Technical FAQ
Q1: What materials can be processed by your rotary dryer?
A: Our rotary dryers are versatile and can handle a wide range of materials, including river sand, mineral ore, coal slime, industrial waste, and various chemical raw materials. We provide customized internal lifting flight designs based on the specific moisture and flowability of your material.
Q2: How to calculate the fuel consumption of a rotary dryer?
A: Fuel consumption depends on the initial and final moisture content of the material, as well as the heat source type (coal, gas, or biomass). Generally, evaporating 1 ton of water requires approximately 650,000 to 750,000 kcal of heat. We can provide a detailed energy consumption report based on your specific requirements.
Q3: What are the main components that ensure a long service life of the dryer?
A: We use high-strength Q235B or alloy steel for the drum, and the supporting rollers and tires are made of forged steel with heat treatment. Additionally, our heavy-duty girth gear and precision-engineered drive system ensure stable operation under high temperatures.
