Product Overview
The CRUSTION CTK series feeders and pre-screeners are stationary feeding equipment specially designed for crushing systems, comprising three main types: bar feeders, bar pre-screeners, and trough feeders. This series is widely used in the primary crushing feeding stage across industries such as mining, metallurgy, and building materials, undertaking the critical task of providing continuous, uniform, and metered feed to crushers. The CRUSTION CTK series feeders and preliminary impurity-removal screens are matched with CRUSTION CVF series feeders to achieve a compact structure for preliminary screening. Most of these feeders are employed in mobile units (crawler or wheeled), and they are also very convenient for installation in stationary setups. By utilizing different types of bars, the CRUSTION CTK series feeders deliver outstanding efficiency in impurity removal and screening (vibrating bars, zigzag plates, anti-blocking plates).

Working principle
The CRUSTION feeder generates vibratory force through a vibrator. The vibrator typically consists of an electric motor and eccentric blocks: the motor drives the eccentric blocks to rotate, producing a periodic eccentric force. This vibratory force is transmitted to the connected feeding trough, causing it to vibrate periodically and driving the material to slide or roll along the trough. By controlling the operating state of the vibrator, the feed rate can be precisely adjusted to meet the requirements of different processes or equipment.

Product Advantages
1. Robust construction with strong impact resistance
The CTK series feeders feature a heavy-duty design capable of withstanding direct impacts from large material loads delivered by loaders or dump trucks. The machine frame is welded from high-strength steel, and replaceable wear-resistant liners are installed in critical wear areas to ensure long-term reliable operation under harsh conditions.
2. Flexible excitation method and stable operation
This series uses an unbalanced motor as the primary excitation source, and some models can be optionally equipped with a hydraulically driven exciter. This design ensures smooth and reliable operation with high availability, while efficiently transmitting dynamic loads to the supporting structure to maintain continuous and uniform feeding.
3. Rod-type structure, also providing pre-screening functionality
While feeding material, the bar feeder and pre-screen can separate fines and oversize particles through the gaps between the bars, sending only large pieces to the crusher. This design effectively reduces the crusher’s load and enhances the throughput and efficiency of the entire crushing system.
4. Highly compatible and adaptable to mainstream crushing equipment.
The CTK series feeder has excellent compatibility with CRUSTION and mainstream crushing equipment.
The bar feeder is compatible with CJ-series jaw crushers, CNP-series impact crushers, and CGP/CHP-series cone crushers.
Bar screens and trough feeders can be seamlessly integrated with CVF series vibrating screens and other downstream equipment.
