Product Overview
Industrial Single Cylinder Dryer is a common rotary drying equipment for bulk industrial materials. It also widely named single drum rotary dryer and direct heated single cylinder dryer in global industrial markets.
This machine use a single rotating cylinder as the main working body. Hot air flows inside the cylinder to remove moisture from raw materials.
It support continuous large-scale drying production. The whole structure is simple and stable. It fit most mineral, agricultural and industrial waste material processing.
Different from multi-cylinder dryers, single cylinder drying equipment have lower failure rates. It cost less for daily operation and routine maintenance.
Technical Parameter Comparison
Different equipment sizes bring obvious differences in processing capacity and energy consumption. The table below shows verified standard parameters of mainstream Industrial Single Cylinder Dryer models.
All test data comes from official industrial equipment test reports and factory standard operating parameters.
Model Size (Diameter × Length) | Processing Capacity (t/h) | Main Motor Power (kW) | Cylinder Rotation Speed (r/min) | Max Inlet Temperature (°C) |
Φ1.5m × 12m | 5.0 - 10.0 | 11.0 | 1.5 - 6.0 | 700 |
Φ1.8m × 18m | 10.0 - 18.0 | 18.5 | 2.0 - 6.0 | 750 |
Φ2.6m × 24m | 27.2 - 34.0 | 75.0 | 1.5 - 5.0 | 800 |
Small-sized single cylinder dryers suit small-batch production lines. It save space and initial investment cost.
Large models provide high hourly output. It meet mass production demands for large industrial plants.
All standard models can reduce raw material moisture from 25% to below 12% after one-time drying process.
Core Structural and Working Features
Stable Rotary Drying Structure
The single cylinder design has fewer wearing parts. The whole machine run smoothly with low vibration.
Internal lifting plates flip materials continuously. It make full contact with hot air for even drying effect.
High Heat Utilization Efficiency
Most Industrial Single Cylinder Dryer adopt direct heating mode. Hot air and materials move in counter flow inside the cylinder.
This working method reduce heat waste. The heat utilization rate can reach 80% in standard working conditions.
Wide Material Adaptability
The equipment can process various bulk materials. It handle sawdust, sand, sludge, coal slime and mineral slag well.
It no strict requirement on material particle size. It support mixed material drying in actual production.
Common Industrial Application Scenarios
Mining and Mineral Processing
Single drum rotary dryer process wet mineral slag and ore particles. It remove excess moisture for further grinding and processing.
Stable drying quality improve finished mineral product qualification rate.
Biomass and Wood Processing
Sawdust, wood chips and biomass raw materials need this dryer for dehydration. Dry biomass materials suit fuel pressing and reuse.
Building Materials Production
Construction sand and industrial sludge are common processing objects. Dried sand can be used for concrete and mortar production directly.
Basic Operation and Maintenance Tips
Check cylinder rotation and bearing status before startup. Abnormal noise means part wear or loose connection.
Control feeding speed steadily. Fast feeding cause uneven drying. Slow feeding waste heat energy.
Clean internal dust and residual materials regularly. Long-term accumulation affect drying efficiency.
Add lubricating oil for rotating bearings every one month. It extend equipment service life.
Industry FAQs
Q1: What materials can industrial single cylinder dryer process?
It mainly process bulk granular materials, including mineral slag, coal slime, construction sand, sawdust, biomass particles and industrial sludge. It adapt most non-viscous industrial raw materials.
Q2: What moisture adjustment range does this dryer support?
Standard models can dry raw materials with 20%–30% initial moisture. The final moisture can be stably controlled below 12% after drying.
Q3: What is the main advantage of single cylinder dryer vs multi-cylinder dryer?
Single cylinder structure is simpler. It have lower failure rate, easier maintenance and lower operating cost. Multi-cylinder models have higher efficiency but need more investment and daily upkeep.
Q4: What is the normal service life of industrial single cylinder dryer?
With regular maintenance, the main cylinder body can work more than 10 years. Wearing parts like bearings and lifting plates need periodic replacement every 1–2 years.
