Rotary Drum Dryer is designed to dry the material which contains high moisture up to 50%. The dried material can be used for making Briquettes and Pellets or for other heating purposes.
Input Raw material: It has the ability to taken the majority of raw materials because it is less sensitive to size of the material. It can dry: sawdust, press mud, paddy straw, bagasse, veneer waste, MSW, Sugarcane straw etc.
FAQs
A rotary drum dryer is a type of industrial dryer that is used to reduce or remove the moisture content from various materials. It is commonly used in the food, mining, chemical, and pharmaceutical industries, as well as in agriculture for drying crops and animal feed. The dryer consists of a rotating drum that is heated by gas or electricity, and the material to be dried is fed into the drum at one end and discharged at the other.
The rotary drum dryer operates on a principle of direct contact between the material and the drying medium. The hot gas or air passes through the drum and comes into direct contact with the material, which causes the moisture to evaporate. The evaporated moisture is then carried away by the gas or air, leaving the material dry.
The dryer can be designed to operate in either a co-current or counter-current mode, depending on the material being dried and the desired moisture content. In co-current mode, the material and drying medium move in the same direction, which results in a faster drying time. In counter-current mode, the material and drying medium move in opposite directions, which results in a slower drying time but a more uniform moisture content.
Overall, the rotary drum dryer is a versatile and efficient machine that is used to dry a wide range of materials in various industries. Its ability to operate in either co-current or counter-current mode, along with its high heat transfer efficiency, make it an ideal choice for many drying applications.
Rotary drum dryers offer several benefits over other types of industrial dryers. Here are some of the key benefits:
High capacity: Rotary drum dryers can handle large quantities of material, making them ideal for industrial applications.
Versatility: These dryers can be used to dry a wide range of materials, including biomass, minerals, chemicals, and food products.
Efficiency: Rotary drum dryers are highly efficient and can reduce moisture content in materials to as low as 10%.
Customization: Rotary drum dryers can be customized to meet specific drying requirements, including material composition, moisture content, and desired end-product characteristics.
Energy savings: Rotary drum dryers are designed to be energy-efficient, and can be equipped with heat recovery systems to reduce energy consumption.
Low maintenance: These dryers are simple to operate and require minimal maintenance, making them a cost-effective option for many industries.
Environmentally friendly: By reducing moisture content in materials, rotary drum dryers can help reduce greenhouse gas emissions and promote sustainable manufacturing practices.
Overall, rotary drum dryers are a reliable and efficient solution for drying a wide range of materials in various industries. Their high capacity, versatility, and energy efficiency make them a popular choice for many manufacturers.
The primary purpose of a rotary drum dryer is to reduce the moisture content of a material or product. The process involves feeding the material into a rotating drum and exposing it to hot gas or air, which circulates through the drum and removes moisture from the material. The dried material is then discharged from the drum.
Rotary drum dryers are used in a variety of industries and applications where drying is necessary, including:
Biomass: Rotary drum dryers are commonly used to dry biomass, such as wood chips, sawdust, and agricultural residues, for use as fuel or feedstock.
Mining: These dryers are used to dry minerals, such as iron ore, copper concentrate, and nickel ore.
Chemicals: Rotary drum dryers are used to dry chemicals, such as fertilizers, pesticides, and other specialty chemicals.
Food: These dryers are used to dry food products, such as grains, nuts, and fruits.
Agriculture: Rotary drum dryers are used to dry agricultural products, such as crops, animal feed, and fertilizer.
In addition to reducing the moisture content of materials, rotary drum dryers can also be used to achieve other objectives, such as:
Improving product quality: Drying can improve the quality of certain materials by removing impurities, contaminants, and odors.
Increasing shelf life: By reducing moisture content, rotary drum dryers can help extend the shelf life of certain products, such as food.
Reducing transportation costs: By reducing the moisture content of certain materials, the weight and volume of the material is reduced, which can lower transportation costs.
Overall, the purpose of a rotary drum dryer is to remove moisture from a material or product to achieve specific objectives, such as improving product quality, increasing shelf life, or reducing transportation costs.
There are several types of rotary drum dryers available in the market. Here are some of the common types:
Single pass rotary dryer: This type of dryer is the simplest and most commonly used. It consists of a single rotating drum through which the material to be dried is fed and discharged. The hot gas or air flows in the same direction as the material, and the drying time is relatively short.
Triple pass rotary dryer: This is a more efficient type of dryer that consists of three rotating drums arranged in a series. The material to be dried passes through each drum in turn, and the hot gas or air flows in the opposite direction. This results in a longer drying time but a more uniform moisture content and higher thermal efficiency.
Direct heat rotary dryer: This type of dryer uses hot gases or air that come into direct contact with the material to be dried. The material is fed into the dryer and discharged from the same end, and the hot gas or air flows in the opposite direction. This type of dryer is suitable for materials that are heat-sensitive or have a low ignition point.
Indirect heat rotary dryer: This type of dryer uses hot gases or air that are heated externally and then passed through a heat exchanger to transfer heat to the material to be dried. The material is fed into the dryer and discharged from the same end, and the hot gas or air flows in the opposite direction. This type of dryer is suitable for materials that require gentle drying at low temperatures.
Overall, the type of rotary drum dryer to use depends on the specific needs and requirements of the user, such as the type of material being dried, the desired moisture content, and the available resources for heating the dryer.
Rotary drum dryers are also known by other names, depending on the specific application and industry. Here are some common names for rotary drum dryers:
