What is the maximum feed size and separation size for the CSR series?

The CSR series roller screening machine can accept a maximum feed size of 1200mm and achieve a maximum separation size of 160mm. This makes it suitable for primary and secondary screening of coal, lignite, and limestone. The actual separation size can be adjusted by changing the roller spacing or screen apertures, but the maximum specified is 160mm. For finer separation, additional screening stages may be required.

How does the CSR series handle wet and sticky materials without clogging?

The CSR series uses a roller-based screening mechanism that does not rely on vibration. Instead, the rollers rotate and convey material across the screen surface, preventing adhesion and clogging. This design is particularly effective for materials with high moisture content, such as wet coal or lignite. The self-cleaning action of the rollers ensures continuous operation, reducing downtime and maintenance compared to vibrating screens.

What are the drive power and weight specifications for different models?

Drive power ranges from 2×7.5kW for the SR1234 and SR1534 models to 6×7.5kW for the SR2464 and SR2474 models. Equipment weight varies from 5.2t for the SR1234 to 23.2t for the SR2474. Intermediate models like the SR2144 have 4×7.5kW and weigh 11.9t, while the SR2454 has 5×7.5kW and weighs 16.7t. These specifications allow selection based on capacity and structural requirements.

Can the CSR series be used for materials other than coal and lignite?

Yes, the CSR series is also suitable for similar non-abrasive, soft materials such as limestone. However, it is not recommended for hard, abrasive materials like granite or ores with high silica content, as these may cause excessive wear on the rollers. For such applications, a different type of screen, such as a heavy-duty vibrating screen, would be more appropriate. Always consult the manufacturer for material-specific recommendations.

How Does the CSR Series Roller Screen Handle Wet and Sticky Materials?

The Cruston CSR series roller screening Machine is a specialized screening solution designed for coal, lignite, and similar non-abrasive, soft materials such as limestone. Unlike conventional vibrating screens, the CSR series employs a roller-based mechanism that operates without vibration, making it exceptionally effective for wet and sticky feed. The machine is available in multiple models, with screen widths ranging from 1.2m to 2.4m and screen lengths from 2.5m to 7.0m. Drive power configurations vary from 2×7.5kW to 6×7.5kW, and equipment weights range from 5.2t to 23.2t. The maximum feed size is 1200mm, and the maximum separation size is 160mm. This range allows operators to select a model that precisely matches their throughput and space requirements, ensuring optimal performance without over-specifying.

Typical applications for the CSR series include coal preparation plants, lignite processing facilities, and limestone handling operations. In these industries, wet and sticky materials often cause traditional vibrating screens to clog, leading to reduced efficiency and increased downtime. The CSR series addresses this pain point directly: its roller design prevents material from adhering to the screening surface, maintaining consistent throughput even with high-moisture content. Additionally, the absence of vibration transmission to the support structure means that the foundation can be lighter and less costly, while also reducing noise and structural fatigue. This makes the CSR series particularly suitable for installations where space is limited or where environmental regulations require minimal dust and noise emissions.

Compared to other models in the CSR series, each configuration offers distinct advantages. For example, the SR1234 and SR1534 are compact units with 2×7.5kW drives, ideal for smaller operations or mobile plants. The SR2144 and SR2454 step up to 4×7.5kW and 5×7.5kW drives, respectively, providing higher capacity for medium-scale processing. The SR2464 and SR2474 feature 6×7.5kW drives and longer screens, making them suitable for high-volume applications. The SR2045 and SR2065 offer alternative width and length combinations to fit specific layout constraints. All models share the core benefits of no vibration, clog-free operation, easy encapsulation, and high efficiency.
