VSI-700-CR Vertical Shaft Impact Crusher 60-100 T/H

The VSI-700-CR represents CONSTMACH's commitment to delivering high-performance crushing solutions for demanding aggregate production environments. This vertical shaft impact crusher, commonly referred to as a sand making machine, operates at the tertiary stage of crushing circuits where the primary goal is achieving superior particle shape and maximizing fine material output. With a production capacity ranging from 60 to 100 tons per hour, this stone crusher handles materials up to 35mm in size, making it particularly effective for processing hard stones like basalt and granite that have already passed through secondary crushing stages.

What sets this VSI crusher apart is its variable speed rotor system, which spins at 60-70 meters per second. This adjustable speed feature allows operators to fine-tune the crushing process based on material characteristics and desired product specifications. The rotor diameter of 700mm works in harmony with the 110kW motor to deliver consistent crushing force while maintaining energy efficiency. The heavy-duty roller bearings ensure smooth operation even under continuous high-load conditions, and the automatic greasing system reduces maintenance downtime significantly.

The machine's versatility comes from its four interchangeable crushing chambers. Operators can swap these chambers depending on feed size requirements and tonnage demands, which means the same stone crusher can adapt to different production scenarios without major modifications. This flexibility is crucial for operations that process varying material types or need to adjust their output specifications. The large symmetrical feed box ensures even material distribution across the rotor, which contributes to both product quality and machine longevity.

High reduction ratio stands as one of the most valuable characteristics of this sand making machine. Unlike conventional crushers that simply reduce size, this VSI crusher transforms angular, irregularly shaped particles into well-formed cubical aggregates. This cubical shape is essential for concrete production and asphalt applications where particle geometry directly affects final product strength and workability. The impact crushing mechanism achieves this by accelerating material through the rotor and directing it against either rock-lined chambers or anvils, depending on the selected crushing mode.

At 6,500 kilograms, the VSI-700-CR maintains a robust construction without becoming unwieldy for installation and relocation. The weight distribution supports stable operation during high-speed crushing while the compact footprint allows integration into existing crushing plants with minimal layout changes. Every component, from the rotor assembly to the feed system, is engineered to withstand abrasive materials and continuous operation cycles that characterize aggregate production.

CONSTMACH designed this vertical shaft impact crusher with practical operational considerations in mind. The automatic greasing system exemplifies this approach by eliminating manual lubrication tasks and ensuring bearing protection remains consistent throughout production shifts. Operators can focus on monitoring material flow and product quality rather than routine maintenance procedures. Combined with the variable speed control, this automation level helps operations achieve optimal performance while reducing labor requirements and operational complexity.
