Symons Spring Cone Crusher

Product Introduction

The Spring Cone Crusher (Symons Type) is a classic, high-performance crushing machine that remains one of the most widely used and reliable crushers in the world. It is perfectly suited for secondary and tertiary (medium and fine) crushing of various materials, including hard rock, ores, and construction aggregate.

Its design is the industry standard for simplicity, reliability, and low operating cost. This crusher is renowned for its strong crushing force, high efficiency, long service life, and easy adjustment.

Overview of Advantages

1. Spring Overload Protection:
   The robust spring system provides reliable overload protection, allowing uncrushable materials (like tramp iron) to pass through the crushing chamber without damaging the machine, reducing costly downtime.
2. Reliable Oil/Grease Sealing:
   The machine adopts a reliable oil or grease seal (depending on the model) to isolate dust from the lubricating oil. This ensures the protection of the internal drive components and guarantees reliable operation.
3. Multiple Cavity Types:
   A wide range of crushing chambers are available (Standard, Medium, and Short Head) to meet diverse customer needs, from coarse crushing to fine crushing.
4. Low Operating & Maintenance Cost:
   The structure is simple, reliable, and easy to adjust. Due to the reasonable selection of parts and structural design, the service life is long, and wear parts consumption is low.
5. High Efficiency & Capacity:
   This crusher provides strong crushing force and high efficiency, resulting in a large processing capacity and reduced downtime.

Cavity Type Selection

This series offers three distinct cavity types to match your application:

• Standard (XLB): Features a larger feed opening. Ideal for secondary (medium/coarse) crushing.
• Medium (XLZ): A versatile choice suitable for medium to fine crushing.
• Short Head (XLD): Features a parallel crushing zone. Ideal for tertiary (fine) crushing to produce the smallest product sizes.

Working Principle

The motor drives the eccentric shaft, causing the movable cone to swing inside the fixed cone (concave). This motion continuously squeezes and crushes the material fed from the top.

This crusher utilizes lamination crushing, where material is also crushed against itself, resulting in a superior, cubical product shape. The robust spring system acts as a reliable overload protection, allowing uncrushable objects (like tramp iron) to pass through safely and preventing damage to the machine.
