Cruston's CVF series feeders are vibrating bar feeders specifically designed for primary crushing applications. Built upon years of engineering experience, this series is designed for heavy-duty applications and is widely used in mines, quarries, gravel pits, and crushing and screening contracting operations to process rocks, gravel, slag, recycled materials, and industrial materials.

The CVF series feeder is a heavy-duty vibrating bar feeder engineered for primary crushing circuits. It utilizes a strong linear vibration motion generated by modular exciters (MV2, MV3, or 2×MV3) to move materials forward efficiently. The large eccentricity and long stroke capability ensure superior pre-screening of coarse particles, particularly when the feed contains a high proportion of flaky material. This design reduces the load on downstream crushers by allowing fine powder and qualified particles to pass through the bar gaps before crushing. With models ranging from the CVF452-2V (450 tph, 700 mm max feed) to the CVF866-2V (1800 tph, 1500 mm max feed), the series covers a wide range of primary crushing requirements.
The CVF series is widely applied in mines, quarries, gravel pits, and crushing and screening contracting operations. It processes rocks, gravel, slag, recycled materials, and industrial materials, handling both soft and abrasive rock. The feeder's compatibility with Cruston CJ series jaw crushers and CNP series impact crushers, as well as other brands, makes it a versatile choice for mobile, portable, and stationary plants, including open-pit and underground operations. The bar structure pre-screens fine materials, reducing crusher wear and operating costs while maximizing output.
Compared to other feeders in the series, each CVF model is optimized for specific crusher compatibility and capacity. For instance, the CVF452-2V and CVF461-1V are ideal for C100, C110, and NP1313 crushers, while the CVF866-2V pairs with larger C160, C200, NP1620, and NP2023 crushers. The modular exciter design ensures faster spare parts supply and simplified maintenance, reducing downtime. The CVF series stands out for its robust construction, efficient pre-screening, and seamless integration with a wide range of crushing equipment.
