The Cruston CMF series banana screening machine is a heavy-duty solution engineered for continuous operation in mineral processing. It excels when feed material contains a high proportion of undersize particles, making it ideal for metallic and non-metallic ore screening.
The Cruston CMF series banana screening machine is specifically engineered for bulk materials with a high undersize content. Unlike conventional screens, its banana-shaped profile allows a thinner bed depth and higher material velocity, which significantly reduces adhesion and blinding. This design is particularly effective in mineral processing plants where feed streams often contain a large percentage of fines. The CMF series is available in 16 models, with widths from 1.8 m to 3.6 m and lengths from 6.1 m to 8.5 m. Screening areas range from 11.0 m² to 30.6 m², and production capacities span 1900 to 3700 tph. Power requirements vary from 30 kW to 90 kW depending on the model and number of decks.
The CMF series excels in metallic and non-metallic ore processing, including iron ore, copper ore, gold ore, and industrial minerals. Its ability to handle high volumes with a high proportion of undersize material makes it a preferred choice for primary and secondary screening stages. The variable tilt angle configuration allows operators to optimize screening efficiency for specific material characteristics, such as moisture content and particle shape. This adaptability ensures maximum operating returns and reduces the need for multiple equipment types. Additionally, the high-speed material movement minimizes adhesion, which is a common issue when screening sticky or wet ores.
Compared to other models in the Cruston lineup, the CMF series stands out for its heavy-duty construction and round-the-clock reliability. The simple and reliable design, combined with readily available spare and wear parts, ensures continuous operation with minimal downtime. While some screens may require frequent maintenance in high-undersize applications, the CMF series is built to withstand the most demanding settings. Its modular design allows for easy adjustment of tilt angles, and the double-deck configurations (e.g., CMF 1861-2, CMF 2461-2) provide increased screening area without a proportional increase in footprint. This makes the CMF series a cost-effective solution for high-capacity operations.
