Gentle Screening Solution for Microcrystalline Cellulose
We received an inquiry from a U.S. pharmaceutical raw material supplier seeking a cellulose tumbler screen solution for its microcrystalline cellulose production line. The customer required a high-efficiency, low-noise screening system that would not damage the material while increasing hourly production capacity and improving the working environment.

Customer Requirements for Cellulose Tumbler Screen
Following detailed communication, the customer specified several key requirements:
- Material: Microcrystalline cellulose (fragile and easily damaged during processing)
- Screen Mesh Size: 1.6 mm to ensure particle consistency
- Capacity Requirement: 2 tons/hour
- Operating Requirement: Low equipment noise to minimize impact on the workshop environment
- Voltage Standard: 415V to match the existing power system
The customer emphasized that their previous screening equipment frequently caused material breakage and generated excessive noise. They were looking for a solution that could provide efficient screening performance while protecting material quality.
Cellulose Tumbler Screen Solution
After thoroughly understanding the material characteristics and production requirements, our engineering team recommended a 1200 mm Tumbler Screen.
The tumbler screen simulates manual screening movement, with vertical acceleration approximately 4–5 times lower than that of a conventional vibrating screen. This significantly reduces the impact force on the material and effectively prevents damage during the screening process.
To meet the customer’s production requirements, we optimized the equipment parameters to ensure a stable output of 2 tons per hour while maintaining high screening precision.

Cellulose Tumbler Screen Features
Higher Processing Capacity
Compared with traditional screening equipment, the tumbler screen can achieve up to five times higher processing capacity per unit area.
Gentle Screening Movement
The tumbler screen effectively simulates manual screening action and creates a gradually expanding spiral movement path on the screen surface. This minimizes material breakage and maintains the integrity of microcrystalline cellulose particles. The material also travels a longer screening path within the same screening area, achieving a screening accuracy of 90–95%.
Easy Maintenance and Flexible Configuration
The equipment adopts a compact, modular circular design that allows quick screen replacement and convenient cleaning and maintenance. The discharge outlet can be adjusted freely within a 360° range, making the process layout more flexible.
Low Noise and Stable Operation
The advanced vibration isolation design significantly reduces operating noise compared with traditional vibrating screens. The equipment is designed for 415V power systems and ensures long-term stable operation.
Fully Enclosed Dust-Proof Structure
The fully enclosed structure provides excellent sealing performance and dust control, virtually eliminating material leakage. This improves environmental performance and creates a safer operating environment for workers.


Customer Feedback
After installation and commissioning, the customer expressed high satisfaction with the screening performance:
“The Tumbler Screen operates very smoothly. The microcrystalline cellulose particles remain intact, the production capacity meets expectations, and the noise level is well controlled. The overall working environment in the workshop has become much more comfortable.”
The customer also specifically mentioned that they were impressed by our professional recommendations and effective communication during the solution design stage, making the entire purchasing process smooth and efficient.
Conclusion
If your production process faces similar screening challenges and you need to improve efficiency while maintaining material integrity and production capacity, please contact our team. We can provide customized screening solutions based on your material properties and production requirements to help make your production process more efficient and stable.
Furthermore, the equipment employs a low-frequency, gentle screening method, which effectively minimizes the generation of fine particles and material loss. This makes it particularly well-suited for industries—such as pharmaceuticals and food processing—that place high demands on particle integrity, thereby helping clients further enhance product quality and production stability.
