How Does the CVG Series Bar Pre-screening Machine Enhance Crushing Efficiency?
The Cruston CVG series bar pre-screening Machine is a heavy-duty pre-screening solution designed to optimize the performance of primary crushers in aggregate, mining, and recycling applications. Available in six models, from the CVG527-2V with a 1.3 × 2.7 m screening area and 15 kW power, up to the CVG860-4V with a 2.0 × 6.0 m area and 55 kW power, the CVG series offers production capacities ranging from 500 to 1,500 tph and can handle maximum feed particle sizes from 900 mm to 1,500 mm. Each model is equipped with an MV exciter (MV2, MV3, MV4, or dual MV3) that generates high excitation force, and the eccentricity is adjustable to fine-tune screening efficiency. The pre-screening bars are inclined at 5° to reduce material stickiness, particularly with viscous feeds or those containing fine powder, thereby increasing output and reducing crusher wear.
The CVG series is engineered for the most demanding working conditions, including abrasive materials and high-throughput operations. It can be integrated into both stationary and mobile crushing systems, and it accepts feed from various feeder types such as push feeders, plate feeders, or vibrating trough feeders. The speed and amplitude can be easily adjusted to ensure an optimal feed rate for the downstream coarse crusher. With a large eccentricity, the machine can generate up to 5.5G of excitation force, ensuring efficient separation even under heavy loads. The vibrator beam is weld-free and entirely connected with Hooke bolts, providing a robust structure that withstands vibration and impact. The MV vibrator and universal joint design are safer and more reliable than direct belt drive, reducing maintenance and downtime.
Compared to other pre-screening equipment, the CVG series stands out for its compatibility with a wide range of crushers, including C100, C110, C125, C3054, NP1315M, NP1415M, NP1313, NP1415, C140, NP1418, C160, NP1620, C200, and NP2023. This makes it a versatile choice for operations that may change crushers or require flexibility. The ability to equip various types of bars ensures broad sorting applicability, allowing adaptation to different material characteristics. Additionally, the weld-free vibrator beam and Hooke bolt connections simplify maintenance and extend service life. With models covering capacities from 500 to 1,500 tph, the CVG series can match the needs of small to large operations, providing a reliable pre-screening solution that maximizes crusher efficiency and minimizes operating costs.
