VSI Vertical-shaft Sand Making Machine is commonly known as the impact crusher or aggregate shaper. VSI Sand Making Machine is the fourth generation of high-performance sand-making machine developed by LIMING on the basis of introducing advanced German technologies about Sand Making Machines and analyzing domestic situations of mining industry. Taking VSI Sand Making Machine as the prototype, LIMING has pushed out upgraded VSI5X Sand Making Machine and VSI6X Sand Making Machine successively.

Granite, quartz, basalt, pebble, limestone, dolomite, etc. Mechanism sand, bituminous concrete, metal mine, aggregates shaping.

Big Capacity, Uniform Granularity
The biggest throughput capacity can reach 520 tons per hour. Compared with traditional equipment, under the same power, the yielding of VSI Sand Making Machine increases by 30%. Besides, the finished aggregates have excellent cubic shape, reasonable granularity and adjustable fineness modulus, exceptionally suitable for artificial sand production and aggregate shaping.

Easy Operation & Maintenance
The VSI Sand Making Machine is light and has several installation manners. Its operation is easy and simple. Once the specific using purpose is determined, users can take full advantages of the Sand Making Machine by making small adjustments. The crusher is equipped with a hydraulic opening device which facilitates checks and replacement of parts inside the crushing chamber, saving time and labor a lot.

Vulnerable Parts Have Low Consumption but Long Service Life
The optimized impact angle of crushing chamber reduces frictions between materials and wear-resistant parts, which further cuts using costs of the VSI Sand Making Machine. The standard dilute-oil lubrication station absolutely solves the heating phenomenon of bearings and keeps the bearing of axis at a constant temperature. So VSI Sand Making Machine’s maintenance period and service life are extended directly.

Advanced Technologies, Eco-friendly Production
Advanced technologies and high-quality makings used in core parts lower the failure rate of VSI Sand Making Machine. Unique damping design effectively lowers noises of the working VSI Sand Making Machine. The use of special air circulatory system greatly drops wind exhaust and dust emission volume, green and eco-friendly.

Digitalized Processing, Higher Precision
There are tens of lines of numerical controlling machine tools. Operations such as steel plates' cutting, bending, planing, milling and paint spraying are all controlled numerically. The machining precision is high, especially for the core parts.

Sufficient Supply of Spare Parts, Worry-free Operation
LIMING, whose businesses cover production and sales, takes responsibility for every machine produced by ourselves. We can offer customers technical services about products and original spare parts to ensure the worry-free operation.

1. Center Feeding: Raw material falls down into feed hopper, then enters impellor through central entrance hole. It is accelerated in high-speed impellor, then is thrown out at speed of 60-75m/s. When hitting impact plate, it is crushed. Final products come downwards through outlet.

2. Ring Feeding: Raw material falls down into feed hopper, then through ring, it is divided into two parts by material-dividing plate. One enters into impellor through the center of material-dividing plate. The other falls down from outside of material-dividing plate. Material, which is thrown out by impellor at speed of 60-75m/s, hits material coming down from outside of material-dividing plate. In this way, material is crushed.
