Our VSI sand making machine is a high-performance vertical shaft impact crusher designed for fine crushing and particle shaping of hard rock, ore and mine tailings. Using a rock-on-rock crushing principle, it produces 0–5 mm manufactured sand with excellent cubical shape and lower wear-part consumption than horizontal impact crushers on hard materials such as granite, basalt and iron ore. Widely used in aggregate plants, sand production lines and mineral processing circuits for pre-grinding fine crushing.
CRUSHING & SCREENING EQUIPMENT
Sand Making Machine
(VSI Vertical Shaft Impact Crusher)
Product Overview
The VSI vertical shaft impact crusher, widely known as sand making machine, adopts mature rock-on-rock crushing principle. It is specially engineered for fine crushing and particle shaping of hard rock, various minerals and mine tailings. The high-speed rotating rotor accelerates raw materials, generating intense collision and self-grinding to produce well-graded, cubical-shaped fine aggregate and manufactured sand. It is widely deployed in aggregate batching plant, highway & railway construction, mineral processing projects and mine tailings recycling. This equipment can also serve as pre-grinding fine crusher ahead of ball mill circuits, effectively reducing ball mill feed particle size, cutting grinding energy consumption and improving overall plant throughput.
Core Advantages
- Rock-on-rock crushing mode, minimal metal wear when processing hard rock, low operating cost
- Produces excellent cubic particle shape, meets high-standard manufactured sand requirements
- Modular rotor design, easy access for maintenance and quick replacement of wear parts
- Flexible capacity range, available for small pilot mines and large-scale industrial projects
- Supports mine tailings reprocessing to produce high-value manufactured sand for extra revenue
- Dual crushing modes optional: rock-on-rock for abrasive hard ore, rock-on-iron for high crushing ratio
- Reliable heavy-duty bearing assembly, continuous long-hour operation under harsh mining site environment

FAQ
Q1: Can this VSI crusher produce qualified 0-5mm manufactured sand?
Yes. The sand making machine is specially designed for 0-5mm fine sand production and particle shaping, the cubical aggregate meets international construction sand standards.
Q2: Can it be used as pre-grinding crusher before ball mill?
Yes, it can reduce feed particle size significantly, help ball mill save energy and raise overall plant processing capacity.
Q3: What kind of raw material is not suitable for this machine?
Highly wet sticky clay material is not recommended, which will block the rotor and discharge port and reduce crushing efficiency.
Q4: Is custom design available for our mining project?
Yes, we support customized machine model, motor configuration, wear part material and whole production line layout according to your ore property and site condition.
Q5: What spare parts need regular replacement?
Rotor tip, impact block, lining plate, feed hopper liner. We can supply full set of wear parts together with machine for long-term operation.
Q6: What after-sales service do you provide?
We provide on-site installation guidance, operator training, remote technical support and lifetime spare parts supply service.
Q7: What is your delivery lead time?
