The Right Investment for Your Paper Mill-Internally Fed Rotary Drum Screen
Project Overview
Our client is an Algerian paper mill requiring a reliable solid-liquid separation solution:
- Front-end process: The thickener produces a mixture of paper and water with a consistency of up to 0.3 g/L.
- Back-end process: Paper fibers are recovered in solid form and returned to the pulper, while the water is recovered and sent to the dissolved air flotation (DAF) unit.
Customer Requirements
The client requires an Internally Fed Rotary Drum Screen with the following specifications:
| Parameter | Requirement |
| --------- | ----------- |
| Treatment capacity | 165 m³/h |
| Screen mesh size | 60 mesh |
| Inlet design | Open inlet to allow easy connection to the feed pipe |
| Required accessories | Collection trough for white water, control panel, motor and gearbox, backwashing device (sprayers, water pump, wire brush, etc.) |
Recommended Model
JXN-1500×4000 (Stainless Steel 304)
Why Choose Our Equipment – Value Over Price
We understand that our pricing is higher than some other suppliers. However, we would like to emphasize that this investment is well justified by the superior quality and long-term cost savings offered by our equipment.
Key advantages of our internally fed rotary drum screen:
| Component | Advantage | Expected Service Life |
| --------- | --------- | --------------------- |
| Drive system | Center bearing + gear drive + bottom support rollers ensure excellent concentricity and smooth operation | 15+ years (with regular lubrication) |
| Filter screen | Wedge-wire screen structure with external support – highly durable and wear-resistant | 15+ years (no replacement needed) |
| Bottom support rollers | High-quality material for long-lasting performance | 3+ years |
We have also provided references from real projects where our equipment has been successfully delivered, demonstrating its reliability and performance over the years.
Alternative Options Offered (For Budget Consideration)
To give the customer more flexibility, we also proposed two alternative solutions with lower initial investment:
Option 1 – Rotary Drum Screen with Woven Wire Mesh
- Lower upfront cost
- However, the woven mesh needs to be replaced approximately every 1 year
- Suitable if the client has a tighter budget
Option 2 – Three (3) Units of DSM Screen (Static Sieve)
- Lower initial capital expenditure
- However, filtration efficiency and service life are comparatively lower than the rotary drum screen
Final Decision
After thorough negotiation and comparison with multiple suppliers, the client has finally decided to proceed with the purchase of:
- One (1) Internally Fed Rotary Drum Screen (Model JXN-1500×4000)
- One (1) Vertical Multistage Pump with integrated control system
The inlet opening and the bottom structure of the drum screen have also been customized according to the client's specific requirements to ensure seamless integration with their existing piping and foundation.
Conclusion
We are confident that our equipment will deliver long-term value, operational stability, and minimal maintenance costs, making it the most cost-effective choice over the equipment's full lifecycle. We look forward to a successful cooperation and a long-term partnership.
