Symons Cone Crusher Feed

You may be facing this dilemma: The actual output of your equipment consistently falls short of its design capacity. Reducing the discharge opening size decreases output; increasing it results in substandard product particle size. You repeatedly weigh output and quality, unable to find a balance.

Solution: The core technology of the superior cone crusher is layered crushing—allowing materials to form a layer within the crushing chamber, achieving crushing through mutual compression between materials, rather than relying solely on the direct impact of the liner plates.

① Stroke extension of 18%~25% — By optimizing the eccentricity of the eccentric sleeve's inner hole and the fit dimensions of the main shaft's spherical bearing, the oscillation amplitude per revolution of the moving cone increases, processing more material per cycle.

② Meshing angle reduction of 2°~4° — Reducing the angle between the upper and lower walls of the crushing chamber reduces material slippage, enhances biting ability, and increases throughput.

③ Parallel zone extension of 15%~20% — The material has a longer "shaping" stroke near the discharge opening, enhancing fine crushing ability and improving the yield of qualified finished products.

Results: Taking the ZYS-5.5FT for processing medium-hard limestone as an example, the traditional design capacity is about 220~250 t/h, and the actual measured capacity after optimization is 280~310 t/h, an increase of about 25%.

1. Optimize the crushing chamber structure to improve the processing capacity per unit time and meet the needs of continuous high-yield operations in mines and quarries.

2. Superior finished particle shape: Employing the principle of layered crushing, it effectively increases the proportion of cubic particles and reduces the content of needle-like and flaky particles, better meeting the standards for highway, high-speed rail, and commercial concrete aggregates.

3. Extended service life of wearing parts: High-manganese steel or high-chromium wear-resistant materials combined with a dry sealing system effectively reduce dust entry into the bearing system, extending the service life of key components and reducing maintenance frequency.

4. Stable and reliable continuous operation: The main unit adopts a high-strength cast steel frame, suitable for continuous crushing of high-hardness materials with a compressive strength ≤350MPa, such as granite, basalt, and iron ore.

5. Shorter downtime: The hydraulic clearing system quickly removes material blockages, reducing manual disassembly time and increasing equipment uptime.

6. Lower energy consumption: Optimized eccentricity and crushing chamber structure reduce unit energy consumption while ensuring output, helping customers reduce long-term operating costs.
