Product catalog summary
Introduction
Metso's HRC™800 crusher is designed for flexibility and efficiency in construction applications, particularly for tertiary or quaternary crushing to produce products like grit, fine gravel, dust, and artificial sand. The crusher's patent-pending technology allows it to adjust crushing pressure based on feed material and processing type, suitable for both open and closed circuit operations.
Design and Technology
The HRC™800 maintains a consistent crushing pressure through hydraulic cylinders and accumulators, with a unique design featuring mutually pivoting housings. Unlike conventional roll crushers, it uses a free-floating gap that adjusts automatically to feed material characteristics, enhancing flexibility and efficiency.
Operational Benefits
  • Flexibility in feed and energy efficiency
  • Cubical product shape
  • Low dust emission and noise
Successful tests have shown its effectiveness in crushing various materials, including sandstone, basalt, limestone, and ores.
Main Components
The HRC™800 consists of components like coupling, accumulator, crusher base, hydraulic cylinder, electric motor, and roll, among others, each contributing to its efficient operation.
Energy Efficiency
High crushing pressure leads to optimal comminution, low circulating load, and limited liner wear, reducing operating costs. The self-adjusting gap maintains constant crushing force, ensuring consistent product size and extended machine service life.
Environmental Considerations
The machine's balanced rotating parts and low-speed operation minimize vibration and noise, reducing the need for special foundations and lowering dust emissions.
Product Shape and Torque Sharing
Adjustments in feed density and pressure allow for cubic product shapes. An optional VFD controls roll speed, ensuring even wear and reducing energy peaks.
Setup and Maintenance
Quick setup via a control panel allows for easy adjustments. The hydraulic system is user-friendly, with features to protect against uncrushables. Bearings are sealed for longevity, and lining replacement requires minimal disassembly.
Safety and Compliance
The HRC™800 meets all safety regulations, featuring protections on moving parts and hydraulic overload security.
Technical Data
Key specifications include a 110kW installed power, 1800rpm rotation, and a production volume of 70 to 120 tons per hour. The machine's dimensions and weight are also detailed.
Service and Support
Metso offers comprehensive services, including spare parts, wear parts, maintenance, repairs, training, and an Equipment Protection Plan. Their comminution consulting helps optimize processes and improve efficiency.

Experience the difference Energy efficiency Technical studies have proven that the use of high crushing pressure on material is the most ecient way to achieve optimum comminution, resulting in a high reduction ratio. The HRC™ 800 is built on this principle, and the results are a low circulating load and limited liner wear – both major contributors to a low operating cost. Self-adjusting gap The gap automatically adjusts to accommodate the type of feed while maintaining a constant crushing force. The result of this constant force is a consistent, desired product size. Additionally, the force contributes...
