VSI-800-CR Vertical Shaft Impact Crusher 150-200 T/H

The VSI-800-CR stands out as CONSTMACH's specialized solution for producing high-quality fine aggregates and achieving optimal particle shape in tertiary crushing applications. This vertical shaft impact crusher, commonly referred to as a sand making machine in the industry, processes materials up to 40 mm that have already passed through secondary crushing stages. Its primary role is transforming crushed stone into uniform, cubical products that meet stringent construction standards.

What makes this VSI crusher particularly effective is its ability to handle the toughest materials in aggregate production. Hard stones like basalt and granite, which challenge many crushing systems, are processed efficiently through its 800 mm diameter rotor. The machine operates at adjustable speeds between 45 and 60 meters per second, giving operators precise control over product characteristics. This variable speed capability means the same stone crusher can adapt to different material properties without compromising output quality or production rates.

The engineering behind the VSI-800-CR reflects decades of industry experience. Its rotor design incorporates heavy-duty roller bearings that withstand the extreme forces generated during high-speed impact crushing. An automatic greasing system maintains optimal lubrication without requiring constant manual intervention, reducing maintenance downtime and extending component life. These features combine to create a sand making machine that delivers consistent performance shift after shift.

Production capacity ranges from 150 to 200 tons per hour, making the unit suitable for medium to large-scale operations. The machine weighs 12,000 kilograms and requires dual 160 kW motors to power its crushing action. This substantial power input enables the high reduction ratios that VSI crushers are known for, transforming relatively coarse feed material into precisely graded products in a single pass.

Operational flexibility comes from four interchangeable crushing chambers. Each chamber configuration accommodates different feed sizes and tonnage requirements, allowing producers to optimize the stone crusher for specific applications. The large symmetrical feed box ensures even material distribution across the rotor face, which promotes uniform wear and consistent product gradation. This design consideration extends component life while maintaining output quality throughout the wear cycle.

The crushing principle employed by this vertical shaft impact crusher differs fundamentally from compression-based systems. Material accelerates through the rotor and impacts either against stationary anvils or against other particles in a rock-on-rock crushing arrangement. This high-energy impact creates the cubical particle shapes that modern concrete and asphalt production demands, while simultaneously generating the fine fractions necessary for workable mixes.

CONSTMACH designed the VSI-800-CR with practical operation in mind. The variable speed rotor adjusts to changes in feed characteristics without requiring machine shutdown, and the accessible chamber design simplifies wear part replacement. These seemingly small details accumulate into significant advantages over extended production runs, particularly in remote sites where minimizing downtime directly impacts profitability.

For aggregate producers seeking to improve product quality while maintaining throughput, this sand making machine represents a proven technological approach. Its combination of robust construction, operational flexibility, and consistent performance addresses the core challenges of tertiary crushing in demanding applications.
