In artificial sand manufacturing, granite stands as a premier raw material. Its high hardness, compressive strength, and low silica content make it ideal for producing high-quality, durable sand for concrete, asphalt, and premium construction projects. However, choosing the right machine to transform rugged granite rocks into perfectly shaped, fine aggregate is a critical decision that impacts productivity, product value, and operational cost. Vertical shaft sand making machine is the best choice for granite sand making.
- Unmatched Product Shape
This is the VSI’s most significant advantage. Unlike other crushers that use compression or sheer force, a VSI operates on the principle of high-speed impact and attrition. Instead of producing angular, flaky, or elongated particles with weak internal fracture points, the VSI generates highly cubical, well-rounded grains.
- Precise Gradation and Fines Control
A VSI crusher offers unparalleled control over the final product’s particle size distribution. By simply varying the speed of the rotor, the feed rate, and the configuration of the crushing chamber, operators can adjust the output to meet exact specifications.
- The “stone beat stone” Advantage for Abrasive Granite
Granite is highly abrasive. This is where the VSI’s stone beat stone crushing method becomes a major operational benefit. In a stone beat stone configuration, the majority of the crushing is done by granite particles impacting other granite particles. The wear is concentrated on the replaceable anvils and rotor tips, protecting the main machine body from excessive abrasion.
- High Capacity and Efficiency in a Single Stage
The VSI is designed as a tertiary crusher, meaning it takes already-crushed granite (typically 1-2 inches) and transforms it into sand in a single pass. This eliminates the need for multiple crushing stages with screening in between, simplifying the circuit layout, reducing overall plant footprint, and lowering labor costs. For large-scale sand production, this efficiency is a massive economic driver.
