회전식 건조기 개요
A rotary dryer machine is a continuous drying device widely used in industry. Its main body is a horizontally installed rotating cylinder. As materials enter the dryer, the internal lifting plates continuously lift and scatter them while the cylinder rotates. The materials then make full contact with the hot air flowing through the cylinder to complete heat exchange and evaporate moisture.
The rotary drum dryer handles many kinds of wet materials, including wood chips, slag, coal slime, clay, compound fertilizer, feed and distiller’s grains.
Various Rotary Dryer Machine Models and Specifications
RICHI rotary dryer machines come in a variety of models, from single-barrel rotating dryer to triple pass rotary drum dryer, to meet different customer budgets and drying needs. In addition, we also offer customized services. A rotary dryer price ranges from tens of thousands to hundreds of thousands of US dollars.

Technical Features of RICHI Rotary Dryer Machine
RICHI rotary dryer machine has three key technologies: a negative pressure airflow system that improves efficiency, a three-cylinder embedding + lift board design that improves energy efficiency, and an efficient environmental protection system that ensures environmental protection.
√
Negative Pressure Airflow System
- The core air components include a blower and an induced draft fan. The blower blows air into the drum, while the induced draft fan draws air at the end. Strong negative pressure drives the materials to move toward the discharge outlet.
- Through-air circulation transfers heat rapidly and cuts down energy consumption.
- The drum dryer machine comes with zoned hot air chambers to control material temperatures accurately at different drying stages.
√
Triple‑Cylinder & Lifting Flight Design
- The outer cylinder can insulate the inner cylinder with less heat loss, and its external heat dissipation area is about 60% less than that of a single-cylinder drum rotary dryer.
- When the cylinder rotates, the lifting plates scoop up and throw out the materials, allowing full contact between materials and hot air flow and increasing the contact area by more than 50%.
- Materials flow alternately upstream and downstream in three-layer cylinders, stay for long periods, and have much higher thermal efficiency than traditional single-cylinder dryers.
- High-temperature flue gas passes through the inner, middle, and outer cylinders in sequence, making full use of heat and avoiding energy waste.
√
Efficient environmental systems
- RICHI rotary dryer for sale seals the material inlet and outlet to prevent negative pressure failure and dust leakage.
- Users can configure a two-stage dust removal system. The dusty moist air drawn from the cylinder end first enters the cyclone for primary dust removal, then passes through the bag filter for secondary filtration, ensuring exhaust emissions meet environmental standards.
회전식 건조기의 보조 장비
In the industrial field, a complete drying system, in addition to the core rotary dryer machine, also requires a reasonable combination of complementary equipment such as thermal vents and dust removal systems to achieve efficient, environmentally friendly, and intelligent production goals.
열원 선정
Common thermal stoves mainly include biomass thermal stoves and fuel/gas thermal stoves. Biomass thermal stoves use waste materials such as wood, straw, and rice husks as fuel, greatly reducing operating costs. Fuel/gas thermal stoves are commonly used in some areas with extremely strict environmental requirements
환경 보호 설정
The exhaust components produced during the drying process are complex, including large amounts of water vapor and small amounts of dust. The exhaust must be purified with professional environmental equipment. Cyclone and pulse dust remover are key equipment for exhaust purification, ensuring that the dust content in the exhaust meets the emissions standards requirements for green production.
지능형 제어
RICHI industrial rotary dryer comes with an advanced PLC frequency change control system. This system can monitor changes in the intake amount and moisture content of raw materials in real time, and automatically adjust key parameters such as intake speed, thermal wind temperature, and roller rotation speed.
