The VSI Vertical Shaft Impact Crusher is the culmination of diligence and ingenuity. Its all-in-one design stems from the designers’ field collection of feedback from clients and equipment operators, resulting in increased output, reduced wear costs, extended maintenance cycles, and reduced maintenance time. This has led to the development of a multi-purpose crusher with various feeding and crushing modes, making it the preferred equipment in fields such as stone shaping, manufactured sand production, refractory materials, ball mill feeding, and finished industrial mineral processing.

Application Fields:

Sand and aggregate yards, concrete sand production, dry-mixed mortar, manufactured sand, power plant desulfurization, quartz sand, etc.

Applicable Materials:

River pebbles, granite, basalt, iron ore, limestone, calcite, quartz, diabase, etc.

Working Principle:

The VSI Centrifugal Impact Crusher crushes material by utilizing the high-speed impact and friction between the material particles themselves. The centrifugal impact crusher can not only crush rock but also shape it. Depending on the material’s feeding method, the working form of the centrifugal impact crusher can be divided into full central feeding and central feeding with cascade material (waterfall feeding). Based on the material’s compressive strength and abrasiveness, the working form of the centrifugal impact crusher can be categorized into two crushing methods: “rock-on-rock” and “rock-on-iron”. Therefore, the crusher’s operation can be divided into four forms: central feeding with cascade material “rock-on-rock” and “rock-on-iron,” and full central feeding “rock-on-rock” and “rock-on-iron.”

Material enters the crusher through the feed hopper, falls onto the scatter cone, and is divided into two parts by the distributor plate. One part enters the high-speed rotating impeller through the center of the distributor plate, is rapidly accelerated within the impeller, and is then ejected at high speed from the impeller flow channels. It first impacts and crushes the other portion of the material falling around the periphery of the distributor plate. The two parts then impact the material liner in the crushing chamber together, are rebounded, and obliquely impact the top of the crushing chamber, changing direction to move downward. The material ejected from the impeller flow channels forms a continuous curtain of material. In this way, a single piece of material is crushed through multiple impacts, friction, and grinding actions within the crushing chamber. The crushed material then exits the crushing chamber under gravity and is discharged through the hopper in the lower machine casing.

Product Features:

1. Large Processing Capacity and High Output: With a capacity of $50 \text{ to } 500 \text{ t/h}$, the output is 30% higher and more stable compared to traditional equipment with the same power.
2. Low Wear Part Consumption: The optimal design of the crushing chamber’s material impact angle minimizes friction with wear parts, resulting in an operating cost 30% lower than traditional equipment, directly reducing the equipment’s cost of use.
3. Excellent Product Particle Shape: The product is cubical in shape, with good particle form, reasonable gradation, and adjustable fineness modulus. It is particularly suitable for manufactured sand production and stone shaping, with practical results showing a 30% improvement in sand making and shaping effect compared to other traditional equipment.
4. Hydraulic Device for Easy Maintenance: The hydraulic lid-opening device makes inspection, disassembly, and replacement of internal crushing chamber components convenient and fast, shortening downtime and saving time and effort.
5. Automatic Detection and Safety Reliability: Equipped with an over-vibration display and alarm device, which issues a warning and stops the equipment if abnormal operation occurs, thus protecting the machine.
6. Thin Oil Lubrication and Automatic Maintenance: The German original thin oil lubrication station features a dual oil pump complementary system to ensure oil supply, with automatic shutdown in case of no oil flow or oil pressure. The oil cooling and heating devices ensure that bearing lubrication is always in the optimal state, thoroughly solving issues like bearing overheating, maintaining a constant temperature for the main shaft bearing, and extending the maintenance cycle and service life.
7. Simple Installation and Easy Operation: The equipment is lightweight, offers diverse installation methods, and can be installed as a mobile unit. Installation, repair, and maintenance are simple, and operation is convenient. Once the specific application is determined, the VSI crusher only requires minor adjustments to maximize its excellent performance.
