The JXS-5 Coking coal Vibrating Screen is primarily used in metallurgical coking to determine the size distribution of coke (25–40 mm, 40–60 mm, 60–80 mm, >80 mm) and measure the coke fines content.

During operation, the material is poured into the screen’s feed hopper. Under vibration, the material passes through the first sieve plate, with oversized particles discharged via the outlet chute, while undersized particles fall onto the second sieve plate for further classification. This process continues through four sieve plates, achieving five-level classification.

This mechanical screen replaces manual sieving, reducing labor intensity, improving the accuracy of coke fines measurement, and eliminating human error. Its optimized design ensures a compact structure, easy operation, and reliable performance, meeting all technical requirements of GB/T 2005.

Structure & Working Principle

The machine consists of:

• Frame (welded from various steel profiles, supporting all components)
• Power unit
• Speed reduction unit
• Vibration damping unit
• Screening unit

When powered, the motor drives a flywheel with an eccentric mechanism via a V-belt, generating controlled vibration. The screen operates at a designed amplitude and excitation force, enabling efficient material classification. The machine can operate continuously as needed.

To enhance stability, increase excitation force, reduce mechanical stress, and minimize noise, the machine is equipped with a vibration damping mechanism.
