Explore our core high-performance machinery, designed to maximize throughput and achieve premium final product shapes across global aggregate processing operations.
In the global aggregate processing and mineral beneficiation sectors, the comminution circuit represents both the highest consumer of energy and the primary driver of operational profitability. Among secondary and tertiary crushing technologies, the Symons Cone Crusher 3ft (historically categorized as the 3-foot or 900mm standard/shorthead cone crusher) stands as a foundational monument of mechanical reliability and high-efficiency size reduction.
Originally designed with the traditional spring safety system, the modern 3ft Symons cone crusher has evolved. Today's leading engineering companies, such as Henan Ascend Machinery & Equipment Co., Ltd., have synthesized classic rugged design principles with advanced material science. The result is a machine that offers unmatched performance in crushing hard, abrasive ores and minerals—such as granite, basalt, quartzite, iron ore, and gold-bearing quartz.
From an operator's perspective, the Symons 3ft cone crusher is highly valued because of its optimal combination of chamber design, eccentric speed, and throwing distance. While larger hydraulic cone crushers are often specified for high-capacity regional quarries, the 3-foot Symons crusher remains the primary choice for medium-scale mining enterprises, mobile tracking configurations, and remote processing plants. It balances capital expenditure (CAPEX) with low, predictable operational costs (OPEX) and ease of field maintenance.
The Symons 3ft cone crusher is manufactured in two primary formats: the Standard (Std) type and the Shorthead (SH) type. Understanding the kinematic and geometric differences between these two configurations is essential for mining operators trying to optimize their comminution circuits.
| Parameter / Model Spec | 3ft Standard (Coarse Chamber) | 3ft Shorthead (Fine Chamber) |
|---|---|---|
| Cone Diameter (in/mm) | 3 ft / 914 mm | 3 ft / 914 mm |
| Max Feed Size (mm) | Up to 145 mm | Up to 65 mm |
| Discharge Setting Range (CSS) | 9.5 mm – 50 mm | 3 mm – 16 mm |
| Processing Capacity (t/h) | 45 – 110 t/h | 27 – 72 t/h |
| Drive Motor Power (kW) | 55 - 75 kW | 55 - 75 kW |
| Total Operating Weight (t) | ~11.2 Metric Tons | ~11.5 Metric Tons |
Globally, the demand for Symons cone crushers continues to grow, particularly in developing regions. In Sub-Saharan Africa (Zambia, Tanzania, Sudan) and Southeast Asia, mining projects require machinery that can handle heavy work with minimal downtime. In these regions, access to specialized service technicians can be limited, making the simple mechanical design of the Symons 3ft cone crusher a key operational advantage.
