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 Maker 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 Maker 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 maker 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 Maker. 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 Maker’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 Maker. Unique damping design effectively lowers noises of the working VSI Sand Maker. 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

SBM, 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.

Working Principle

VSI Vertical-shaft Impact Crusher (also known as “Sand Maker”) has two feed modes – “feed at center” and “feed at center & sides”. As for the former mode “feed at center”, materials at the feed hopper firstly pass through the central hole into the high-speed spinning rotor. In the rotor, materials are fully accelerated and thrown outwards from the launching port to collide with a part of materials that freely fall after rebound. Next, materials hit the surrounding vortex material liner (or the impact block) inside the vortex chamber together. In the chamber, materials are bounced to the top of crushing chamber firstly and then change their direction by moving downwards to form a material curtain with materials emitted from the runner of impeller. Finally, finished products are discharged from the bottom discharge opening. As for the latter mode “feed at center & sides”, firstly, materials at the feed hopper pass through the circular hole. Then, materials are divided into two parts by the distributing tray. One part of materials enter the high-speed rotating impeller while the other part of materials fall from all sides of the tray. Materials in the impeller would be accelerated rapidly and thrown outwards at a high speed to collide with materials falling from all sides of the tray. Next, all materials hit the surrounding vortex material liner (or the impact block) inside the vortex chamber together. In the chamber, materials are bounced to the top of crushing chamber firstly and then change their direction by moving downwards to form a material curtain with materials emitted from the runner of impeller. Finally, finished products are discharged from the bottom discharge opening.
