Rotary crushers are essential tools in material processing when both precision and throughput matter. Built for coarse or fine reduction of soft to moderately hard materials, Sturtevant’s rotary crusher delivers high-capacity, uniform performance across demanding industrial applications. Whether you’re working with coal, gypsum, limestone, salt, or chemicals, this rugged machine is designed to reduce materials efficiently using shear forces, not impact or compression. It is ideal for operations that require minimal fines and consistent granulation.
With a legacy of engineering excellence, Sturtevant’s rotary crusher is trusted by manufacturers looking for reliability, adjustability, and durability in their size reduction process.
How Rotary Crushers Work
Sturtevant’s rotary crusher operates through a shear-based size reduction process that ensures consistent particle size without generating excessive fines. As material enters the crusher chamber, it is subjected to grinding forces between rotating grinding nuts and a stationary liner wall. This shearing action breaks down the material in a controlled manner rather than pulverizing it through impact.
Rotary crushers offer a more refined approach to material reduction. They produce a uniform granular product that is well suited for downstream applications. Operators can also adjust product fineness during operation, allowing real-time control without interrupting production.
Key Features of the Sturtevant Rotary Crusher
Engineered for performance and built to last, the Sturtevant Rotary Crusher combines heavy-duty construction with operator-friendly features to deliver reliable, high-capacity crushing for a wide range of materials.
Shear-Based Reduction
Material is reduced by shear forces generated between the rotating grinding nuts and the fixed case wall liner, ensuring consistent granulation without over-grinding.
Adjustable Product Fineness
Operators can modify product size during operation, allowing greater control over output without requiring shutdowns.
Heavy-Duty Cast Iron Construction
The robust cast iron build withstands harsh operating conditions while maintaining long-term structural integrity.
High Throughput Capacity
Capable of processing large volumes efficiently, the rotary crusher is designed for industrial-scale operations.
Easy Access for Maintenance
Wear areas are accessible without special tools, simplifying inspection and maintenance and helping reduce downtime.
Ni-Hard Grinding Elements
For abrasive materials, optional Ni-Hard components extend the life of wear parts and ensure dependable long-term performance.
Applications
Sturtevant Rotary Crushers are a versatile solution for industries requiring consistent and controlled particle size reduction. Their ability to handle soft to moderately hard materials with minimal fines makes them ideal for material preparation and downstream processing.
Typical applications include:
- Coal – Reduces friable coal to uniform size for combustion or processing
- Gypsum – Delivers consistent granules for wallboard, cement, or soil conditioning
- Limestone – Produces material suited for construction, agriculture, or industrial use
- Salt – Ensures even sizing for food-grade, chemical, or de-icing purposes
- Coke – Handles petroleum coke and similar materials with steady throughput
- Industrial Chemicals – Ideal for dry chemicals where uniformity is essential
