Working Principle
VSI Series vertical shaft impact crusher operates on "stone-on-stone" and "stone-on-iron" crushing principles:
Material Feeding: Raw materials enter through the feed hopper and fall into the high-speed rotating impeller
Acceleration: Materials are accelerated to 60-75 m/s by the impeller and ejected through flow channels
Impact Crushing: High-speed materials impact against the lining plate (stone-on-iron) or material curtain (stone-on-stone)
Classification: Crushed materials are discharged through the bottom outlet, with fine particles carried by upward airflow for collection
The "stone-on-stone" mode reduces wear parts consumption and improves particle shape. The "stone-on-iron" mode increases sand production ratio and handles higher feed sizes.
Assembly Verification: Dynamic balancing of rotors, precision alignment of bearings
Factory Acceptance Testing (FAT): 4-hour continuous run test at 110% rated capacity with actual material
Pre-Shipment Inspection: Dimensional verification, hydraulic system testing, documentation audit

Frequently Asked Questions (FAQ)
Q1: What materials can VSI crusher process?
VSI Series handles medium-hard to ultra-hard materials including river pebble, granite, basalt, limestone, quartz sand, and construction waste. Maximum feed size 35-60mm depending on model. For larger materials, pre-crushing with jaw crusher or cone crusher is required.
Q2: What is the difference between stone-on-stone and stone-on-iron crushing modes?
Stone-on-stone: Materials impact against material curtain, low wear parts consumption, excellent particle shape, suitable for shaping. Stone-on-iron: Materials impact against metal lining, high sand production ratio, suitable for sand making. VSI Series allows switching between modes by changing lining plates.
Q3: How to control finished product gradation?
Gradation is controlled by: ① Spindle speed adjustment (higher speed = finer product); ② Feed mode selection (cascade feed increases fines); ③ Screen mesh configuration. Typical manufactured sand fineness modulus 2.2-3.0 adjustable.
Q4: Is VSI crusher suitable for mobile crushing stations?
Yes. VSI-8522 and VSI-9526 are specifically designed for mobile operations with compact structure and quick installation. Widely used in construction waste recycling and temporary mining projects.

Key Factors Affecting Manufactured Sand Quality in Screening
Screening has significant impact on manufactured sand quality. Three critical factors:
Screen Aperture Shape: Manufactured sand production contains high stone powder content with strict grade requirements. Square apertures are generally used, not rectangular or circular holes.
Screen Surface Inclination: For good screening effect and processing capacity, screen surface inclination is generally controlled around 20 degrees.
Screen Aperture Size: Determines finished product particle size distribution. Common configurations: 3.5mm, 2.5mm, 1.25mm, 0.63mm for multi-stage classification.
Recommended Screening Equipment: LF Series Thin Oil Lubrication Horizontal Vibrating Screen for large-capacity stable operation; TS Series Dewatering Screen for wet process moisture control.
