CTK Series Feeders and Prescreens

The CTK series feeders and prescreens are engineered to continuously, uniformly, and quantitatively feed crushers in primary crushing stages. With models like the CTK8-27-2V and CTK16-27, these units handle capacities from 250 to 500 tph and feed sizes up to 700 mm. The bar feeder variants, such as CTK11-42-2V, use a heavy-duty welded steel body with replaceable wear liners to withstand direct impacts from loaders and dump trucks. The excitation system, powered by unbalanced motors or optional hydraulic vibrators (V150 or V175), ensures stable operation and efficient load transfer. This design minimizes downtime and maintains consistent feed rates, which is critical for high-volume mining and aggregate operations.

In mining, metallurgy, and building materials, the CTK series addresses the challenge of handling large, abrasive materials while reducing crusher wear. The bar prescreens, including the CTK11-20-2V and CTK13-20-3V, pre-screen fine particles through bar gaps before material enters the crusher. This reduces the volume of material processed by the crusher, lowering energy consumption and increasing overall system throughput. For mobile installations on tracked or wheeled chassis, the compact design of models like the CTK10-15-2V allows easy integration with CVF series vibrating screens. The trough feeders, such as the CTK10-20, provide a reliable solution for sticky or wet materials, ensuring uninterrupted flow in challenging conditions.

Compared to other models in the series, the CTK12-32-2V stands out with a width of 1.2 meters and a length of 3.2 meters, offering a balance between capacity and footprint. It supports a maximum feed size of 350 mm and production of 500 tph, making it suitable for medium-scale operations. The CTK16-20-3V, with a 1.6-meter width, is ideal for high-capacity prescreening where feed size is limited to 250 mm. These variations allow operators to select the optimal model based on material characteristics and crusher requirements. All models feature strong compatibility with mainstream crushing equipment, including CJ jaw crushers, CNP impact crushers, and CGP/CHP cone crushers, ensuring seamless integration into existing circuits.
