Project Background
In August 2024, Jiarui Machinery provided a powder screening solution for a plastic material processing company in Pakistan. The customer specializes in amino molding compound plastic powder production. During their production process, the existing screening equipment had become a bottleneck. The original machine could not keep up with the required throughput, and frequent screen blockage caused unstable fine powder content in the finished product, creating issues for the downstream production process.
When the customer contacted Jiarui, the requirements were clear: the equipment needed to achieve 60 mesh screening with a capacity of 1200 kg/h, and the screening process could not slow down the production line.
Jiarui’s Plastic Powder Separator Solution
Based on the customer’s material characteristics, Jiarui focused on three key factors: 60 mesh screening accuracy, 1200 kg/h processing capacity, and the powder’s tendency to block the screen during operation. After evaluating the working conditions, Jiarui recommended the JR1500-1S rotary vibrating screen as the core equipment for this Plastic Powder Separator application.
The equipment uses a 1500 mm diameter screening surface, providing a larger effective screening area to meet the customer’s single-deck screening requirements. Since the customer only needed single-stage 60 mesh powder separation, a multi-layer structure was not selected. This design makes future screen replacement and equipment maintenance more convenient.
The material contact parts are manufactured from 304 stainless steel, which is suitable for plastic powder screening applications and helps reduce the risk of material contamination during conveying and screening.

Why Jiarui Recommended the Rotary Vibrating Screen JR1500-1S
The customer’s requirement of 60 mesh belongs to medium-fine powder screening. The JR1500 model provides a sufficiently large screening surface diameter, allowing the material to stay on the screen surface for enough time to achieve proper separation and efficient passing through the mesh.
In addition, considering that the material had a tendency to block the screen openings, Jiarui equipped the 1S model with a rubber bouncing ball cleaning system. During operation, the vibration movement drives the rubber balls to continuously impact the bottom of the screen mesh, helping keep the openings clear and maintaining stable screening efficiency.
The 2.2KW vibrating motor provides sufficient adjustment capacity for a 1.5-meter diameter machine. It can meet the required 1200 kg/h throughput while avoiding excessive vibration that could affect equipment durability.
The JR1500-1S rotary vibrating screen works as an effective Plastic Powder Screening Machine for applications requiring stable particle separation and continuous operation.
Before and After Comparison
| Comparison Item | Before Upgrade (Original Equipment) | After Upgrade (JR1500-1S) |
| Processing Capacity | Approximately 800 kg/h (production bottleneck) | Stable operation at 1200 kg/h |
| Screen Blocking Frequency | Manual cleaning required every 2 hours | Continuous operation for 8 hours without cleaning |
| Finished Product Quality | Excess fine powder carried over, requiring reprocessing | One-pass screening meets downstream requirements |
| Equipment Footprint | Large footprint with loose structure | Compact structure, saving workshop space |
| Maintenance Cost | Fast seal wear and serious powder leakage | Improved sealing structure with no powder leakage |
Project Results
The equipment was installed, commissioned, and put into production in August 2024.
According to the customer’s feedback, the production target was achieved successfully. The equipment can easily maintain the required 1200 kg/h capacity, while the screen cleaning interval has been significantly extended. The previous major issue of frequent screen blockage has been largely resolved.
Because the material contact parts are made of 304 stainless steel, there were no issues with material discoloration or rust contamination during operation. The overall operating noise and vibration remained within an acceptable range.
The customer recognized the performance of this Plastic Powder Separator application and indicated that they would consider continuing with larger models from the same series for future production expansion.
Sonuç
This project represents a typical powder production capacity upgrade case. For amino molding compound plastic powder screening, the main challenge was balancing production capacity improvement with the prevention of screen blockage caused by powder adhesion.
The JR1500-1S achieved improved production efficiency and screening stability through proper screen diameter selection and anti-blocking design, without significantly increasing the customer’s equipment investment.
For manufacturers requiring similar material handling conditions, mesh sizes, or powder separation performance, this project can provide a practical reference for equipment selection.
The Jiarui JR1500-1S can also serve as a reliable Plastic Powder Sieving Machine for industrial powder separation applications.
