鉱山設備ガイド：What Equipment Should You Use for Manufactured Sand Production, Aggregate Shaping and Metal Ore Fine Crushing? A Complete Guide to VSI Series High-Efficiency Vertical Shaft Impact Crushers

The VSI series vertical shaft impact crusher is a vertical shaft impact crusher designed by introducing German technology and combining domestic material production and demand conditions. It can be used for the sand making and shaping of hard stones. It uses a high-speed closed impeller to accelerate materials and can be configured for stone-on-iron or stone-on-stone production modes according to user needs. This equipment applies advanced selective crushing and cleavage crushing principles, directly imparting sufficient kinetic energy to the material and converting this energy into the required crushing force through impact, causing the material to fracture along its natural grain or cleavage planes. Therefore, the products are cubic in shape, with good particle form, reasonable grading, and adjustable fineness modulus, making it especially suitable for artificial sand making and stone shaping. Why choose the VSI series vertical shaft impact crusher? First, it has strong production capacity, with processing amounts of up to 520 t/h, showing a certain increase in output compared with earlier equipment of the same power. Second, it delivers superior product quality, with cubic products, good particle shape, reasonable grading, and adjustable fineness modulus, which is particularly suitable for artificial sand making and stone shaping. Third, it features advanced technology, combining imported foreign technology with domestic needs, and high-quality core component materials ensure a low failure rate for the whole system. Fourth, it is easy to maintain, with a lightweight design and equipped with a hydraulic cover opening device, saving time and effort during part replacement. Fifth, it is versatile; by adjusting the feeding method and crushing chamber structure, it allows quick switching between stone-on-stone and stone-on-iron modes. The VSI series vertical shaft impact crusher is mainly used in manufactured sand production lines, providing high-quality sand and gravel aggregates for highways, high-speed railways, high-rise buildings, municipal projects, hydropower dams, and concrete mixing stations; shaping of aggregates in aggregate mines and manufactured sand production; fine crushing of metallic and non-metallic ores, such as iron and copper ores; as an auxiliary sand and stone production equipment for dry-mixed mortar and cement product factories; and for crushing and shaping various metallurgical slags. The VSI series is needed by sand and gravel pits and aggregate producers, concrete mixing station operators, dry-mixed mortar and cement product manufacturers, metallic and non-metallic mine operators, highway and railway construction units, hydropower dam and high-rise building construction companies, EPC contractors of crushing and sand production lines, equipment distributors and stockists, and overseas infrastructure and mining project buyers. Under what circumstances should you choose or replace a VSI series vertical shaft impact crusher? When high-quality manufactured sand needs to be produced, requiring a cubical, rounded final product with a reasonable gradation; when aggregates need shaping to reduce the content of needle-like or flaky particles; when dealing with metallic ores, non-metallic ores, metallurgical slag, and other materials; when the finished product from an old sand-making machine is poorly shaped, has unreasonable gradation, or wear parts have a short lifespan and need upgrading; when one machine needs multiple uses, freely switching between ‘stone-on-stone’ and ‘stone-on-iron’ modes; when constructing a new large-scale sand production line requiring high processing capacity and energy efficiency; and when export projects require vertical shaft impact crushers compatible with overseas voltage (380V/50Hz). How to choose a VSI series vertical shaft impact crusher? Step 1: Determine the material type and abrasiveness. ‘Stone-on-stone’ type is used for highly abrasive material processing and shaping stones, while ‘stone-on-iron’ type is used for less abrasive materials and sand making. Step 2: Determine the feeding method. Cascade and center feed have higher processing capacity, while full-center feed has lower capacity but better product quality. Step 3: Determine throughput requirements and choose the corresponding model within the 60-520 t/h range according to production line capacity requirements. Step 4: Determine motor power and select a dual-motor configuration from 55×2 kW to 200×2 kW according to throughput. Step 5: Determine the maximum feed size, with 35-50 mm for soft material and 30-45 mm for hard material. Step 6: Confirm voltage configuration, standard 380V/50Hz. Step 7: Confirm the lubrication system, with standard thin oil lubrication station, dual pumps for complementary oil supply, and safety protections such as automatic shutdown when oil flow stops. Step 8: Confirm environmental protection and automation configuration, with optional dust removal system and centralized control system.

Note: The VSI series vertical shaft impact crusher is suitable for materials such as granite, marble, basalt, limestone, quartz stone, river pebbles, and bluestone. The stone-on-stone type is used for processing highly abrasive materials and shaping stones, while the stone-on-iron type is used for processing less abrasive materials and making sand. The sand-making rate of the stone-on-iron type is 10-20% higher than that of the stone-on-stone type. Feeding methods are divided into cascade and center feeding and full center feeding, which can be chosen according to materials and product requirements. Explosion-proof motors need to be selected for explosive environments. For highly abrasive materials, it is recommended to use high-chromium cast iron or ceramic composite wear parts.

Selection considerations (compared with VSI6X and 5X series): The core differences between the VSI series vertical shaft impact crusher and the VSI6X and 5X series high-efficiency centrifuge impact crushers lie inresearch and development foundation, impeller structure, and wear part designThe VSI series is the foundation for the development of the VSI5X and VSI6X series. It introduces German technology and uses high-speed closed impellers to accelerate materials. It is equipped with a hydraulic cover opening device, making maintenance convenient. The VSI6X series features a brand-new four-port deep chamber impeller design, increasing crushing efficiency by about 20% and extending the life of key wear parts by 30%-200%. The 5X series uses a deep-chamber rotor, increasing material throughput by about 30%, and the surrounding wear plates can be turned up and down, extending their life by more than 48%. When selecting, projects with high requirements for basic sand-making shaping function and ease of maintenance are recommended to choose the VSI series; projects with high requirements for efficient crushing using a four-port impeller are recommended to choose the VSI6X series; projects with high requirements for material throughput and turning of the surrounding wear plates are recommended to choose the 5X series.
