VSI Sand Making Crusher

The VSI Sand Making Crusher is a high-efficiency device for producing high-quality artificial sand and shaping aggregates, utilizing "stone-on-stone" or "stone-on-iron" impact crushing with a high-speed rotor (2800–3500 rpm). It is widely used in construction and infrastructure projects, processing granite, limestone, etc., to produce sand with excellent grain shape (cubicity ≥90%, needle-like content ≤10%) and adjustable fineness modulus (2.6–3.0).​ Structurally, it includes a main body (upper cover, crushing chamber, lower frame), rotor assembly (rotor disk, throwing heads, main shaft), feeding system, drive system, and lubrication/cooling system. Key components like the 42CrMo rotor disk and Cr20–25 throwing heads undergo precision forging/casting, with heat treatment to ensure strength and wear resistance.​ Manufacturing involves forging (rotor disk, main shaft), casting (throwing heads), and CNC machining for tight tolerances. Quality control includes material testing, dimensional inspection (CMM), NDT (UT, MPT), and performance tests (dynamic balancing, load runs).​ Installation requires a stable foundation, precise alignment of components, and system commissioning. This crusher ensures efficient production of high-quality sand for modern construction needs.
