Symons cone crusher Introduction

Symons cone crusher is an improved, optimized, and updated replacement product for the PY series spring cone crusher. Compared with the PY series spring cone crusher, it has the characteristics of reliable structure, high production efficiency, easy adjustment, and economical use. The spring safety system of this series of Symons cone crushers is an overload protection device, which can allow metal foreign objects to pass through the crushing chamber without harming the machine. It adopts a dry oil sealing form to isolate the stone powder from the lubricating oil, ensuring reliable operation. It can be widely used in industries such as metal and non-metal minerals, cement plants, construction, and sand and gravel metallurgy. Nonferrous metal ores, granite, limestone, quartzite, sandstone, pebbles, etc.

working principle

When the Symons cone is broken, the eccentric sleeve is driven to rotate by the electric motor through a V-belt, a large pulley, a transmission shaft, a small bevel gear, and a large bevel gear. The axis of the broken cone rotates and moves under the pressure of the eccentric sleeve, causing the surface of the broken wall to sometimes approach and sometimes leave the surface of the rolling bowl wall, thereby causing the material to be continuously compressed, impacted, and bent in the annular crushing chamber composed of moving cones, and broken. After multiple squeezing impacts and bending, the material is crushed to the required particle size and discharged through the lower part.

Performance Characteristics

1. By optimizing the cavity design and combining reasonable speed and stroke, this model can perform the most work under the same dynamic cone diameter. Therefore, compared with similar spring cone crushers, it has higher performance and production capacity.
2. Good particle size composition of the product: The Symons cone crusher adopts the principle of laminated crushing, which significantly increases the proportion of cubes in the product, reduces the number of needle shaped stones, and makes the particle size more uniform.
3. Good stability: When non broken objects such as iron blocks enter the machine, the iron protection device will automatically release them and then reset automatically. The iron protection has a fixed return point for the discharge port, and after the miscellaneous iron passes through the crushing chamber, it can quickly restore the original discharge port.
4. Easy cleaning: If the Symons cone crusher stops under load, the hydraulic cleaning system can quickly clean the crushing chamber, greatly reducing downtime.
5. High reliability: The automatic control system adopts a large diameter spindle, heavy-duty main frame, and independent thin oil lubrication system, ensuring the equipment is sturdy, durable, and reliable in operation.
6. Easy to maintain and operate: All components can be disassembled and assembled from the top or side, making it convenient to remove both the fixed cone and the moving cone assembly. Bronze sliding bearings can maintain excellent load-bearing performance in high impact vibration and crushing environments, and are more economical and easier to maintain than rolling bearings.
7. Low production cost: Due to its large production capacity, high reliability, and convenient maintenance, it greatly reduces production costs.
8. Widely applicable: The Symons cone crusher is characterized by maximizing its performance to be suitable for various crushing processes, from ultra coarse crushing to fine crushing, from fixed crushing to mobile crushing stations.
9. Split lubrication: An independent thin oil lubrication system with multi-point control ensures dual protection of bearing lubrication for this model, as well as automatic safety protection for the entire machine.
