A vertical shaft grinding sand making machine, commonly known as a VSI (vertical shaft impact) sand maker, is a fourth-generation high-performance machine that produces manufactured sand and shaped aggregates from rock. YDL supplies a complete range of vertical shaft impact sand making machines that use high-velocity centrifugal acceleration to grind and shape granite, basalt, limestone, quartz, river pebble and other materials into high-quality fine sand. The machine accelerates material through a deep high-speed rotor and impacts it against a crushing chamber, producing uniform, cubical and well-graded sand. With a maximum feed size of 35–50 mm and capacities from 60 t/h to 520 t/h, both center feeding and center-and-sides feeding options are available to match different output requirements. Backed by in-house cast wear parts, low energy consumption, CE certification and professional installation guidance, our vertical shaft sand maker delivers reliable and profitable sand production.

FAQ
Q: What is the maximum feed size for a vertical shaft sand making machine?
A: The maximum feed size is strictly limited to about 35–50 mm. Feeding oversized material can unbalance the high-speed rotor and cause mechanical failure, so proper pre-crushing is essential before the VSI stage.
Q: What is the capacity range and how do I choose a model?
A: Our models range from 60 t/h to 520 t/h. Models can be fed at the center or at both center and sides to adjust capacity. We recommend the right model based on your raw material, required sand fineness and hourly output.
Q: What materials can the machine process?
A: It processes medium-hard to hard materials including granite, basalt, limestone, quartz and river pebble, producing high-quality fine sand for concrete, mortar and aggregate applications.
Q: How long do the wear parts last and can I buy spares from you?
A: As a foundry, we cast the wear parts in-house and supply spares directly at a stable price. Wear life depends on feed material abrasiveness and operating hours; we can recommend the best material grade for your conditions.
