The capacity of a drum flaker machine is not a fixed number; it depends entirely on the size of the machine and the physical properties of the material being processed.
However, to give you a general idea, capacities typically range from 50 kg/h (110 lbs/h) for small laboratory units up to 10,000 kg/h (22,000 lbs/h) for large industrial plants.
Here is a breakdown of how capacity is calculated and what factors influence it:
Standard Capacity Ranges
Drum flakers are categorized by the dimensions of the drum (Diameter x Length). Larger drums provide more surface area for cooling and solidifying the material.
| Machine Type | Drum Dimensions (approx.) | Typical Capacity Range | Common Use |
| Laboratory / Pilot | 0.4m x 0.4m (16" x 16") | 50 – 200 kg/h | R&D, testing new products, small batch production. |
| Small Industrial | 0.8m x 1.0m (31" x 39") | 200 – 1,000 kg/h | Small chemical plants, specialty food processing. |
| Medium Industrial | 1.0m x 2.0m (39" x 79") | 1,000 – 3,000 kg/h | Standard production lines for soaps, resins, and waxes. |
| Large Industrial | 1.5m x 3.0m (59" x 118") | 3,000 – 10,000 kg/h | High-volume production (e.g., bulk caustic soda, large chemical refineries). |
The Formula: How is Capacity Calculated?
Manufacturers use a specific formula to estimate the capacity based on the drum's surface area and the material's density.
Capacity(kg/h)=Drum Surface Area(㎡)×Film Thickness(m)×Material Density(kg/m³)×Drum Speed(rpm)×60 minutes
Example:
Drum Area: 3㎡
Thickness: 0.001 m (1 mm)
Density: 1,200kg/m³
Speed: 5 rpm
Result:3×0.001×1,200×5×60=10,800 kg/h
Key Factors That Change the Capacity
While the drum size is fixed, the actual output can vary significantly based on these factors:
1. Material Viscosity (Thickness):
* High Viscosity (Thick): Materials like resins or heavy pastes stick to the drum better and form a thicker film. This results in higher capacity.
* Low Viscosity (Watery): Thin liquids run off the drum easily and form a very thin film. This results in lower capacity.
2. Cooling Requirements:
* If a material requires a very low temperature to solidify (e.g., -20°C), the drum speed must be slowed down to allow enough time for cooling. Slower speed = Lower capacity.
3. Melting Point:
* Materials with a high melting point take longer to cool down on the drum surface, requiring slower rotation.
4. Flake Thickness Setting:
* If the operator adjusts the machine to make thicker flakes, the capacity goes up. If they need thin flakes (for fast dissolving), the capacity goes down.
When asking for a drum flaker's capacity, you usually need to specify the material you are processing. A machine rated for 5,000 kg/h of soap flakes might only produce 2,000 kg/h of a thin, low-density chemical solution.
