VERTICAL SHAFT IMPACT CRUSHERS
Vertical shaft impact crushers, used at the tertiary stage, handle abrasive materials to produce cubical products with a high percentage of fines. Three chamber types are available depending on the application: closed rotor with a stone box for very abrasive materials, closed rotor with anvil for medium abrasivity, and open rotor with anvil for softer materials.
Each configuration is optimized for maximum efficiency, addressing specific requirements while balancing performance, uniform crushing, and reduced maintenance costs.
HAMMER CRUSHERS
Hammer crushers are primarily used for secondary and tertiary crushing of soft materials like limestone. They are particularly suited for small feed sizes and allow precise control over the output size through a lower grate system, offering flexibility to achieve the desired material dimensions.
Material classification can be adjusted by modifying the peripheral speed and the gap between the motor and the body. These features make hammer crushers ideal for processing limestone and similar materials, ensuring the production of fine materials with a high powder ratio.
ROLLER CRUSHERS
Roller crushers operate by crushing materials between two rollers rotating in opposite directions. Made from wear-resistant cast manganese steel, the rollers can feature flat or threaded surfaces depending on the desired product size. The gap between the rollers, adjustable via a hydropneumatic system, controls material size and increases capacity as needed.
Suitable for materials of varying hardness and moisture levels, roller crushers offer efficient crushing with minimal dust and a high proportion of fine materials. Their robust transmission system and protected bearings ensure reliable and continuous performance.
