The Crushing and Sand-Making Industry: A Comprehensive Overview

Industry Background
The global construction boom has driven unprecedented demand for high-quality aggregates, making the crushing and sand-making sector a cornerstone of modern infrastructure development. As urbanization accelerates worldwide, particularly in emerging economies like China, optimized crushing plants such as the Viterra China Y90L-4 series have become critical for producing precisely graded sand and stone materials.

Core Technology: Crushing & Sand-Making Equipment
At the heart of any aggregate production line lies the crushing system. The Y90L-4 motor-powered crushing units exemplify industry advancements with:

• High-Efficiency Design: 4-pole motors (like Y90L-4) balance power (typically 1.5kW) and speed (1500rpm), ensuring stable operation for secondary/tertiary crushing stages.
• Versatile Configuration: Jaw crushers for primary reduction, cone/impact crushers for intermediate stages, and VSI crushers for cubical sand production.
• Automation Integration: Modern plants incorporate IoT sensors for real-time monitoring of vibration, temperature, and throughput.



Market Dynamics & Applications
1. Construction Aggregates: Concrete (60% of demand), asphalt, and road base layers require 5–20mm crushed stone with <3% flakiness index.
2. Mechanism Sand: Strictly controlled 0–5mm particles replace natural sand in C30+ concrete mixes.
3. Specialty Applications: Railway ballast (31.5–63mm), architectural precast (3–10mm washed aggregates).

Engineering Case Study
A Guangdong-based producer achieved 250TPH output by configuring:

• Primary: JC546 jaw crusher
• Secondary: GP300S cone crusher (Y90L-4 motors driving auxiliary systems)
• Tertiary: CV218 VSI for sand shaping

This setup reduced needle-shaped particles from 15% to 8%, meeting GB/T14684-2022 standards.

FAQ Section
Q1: Why choose 4-pole motors like Y90L-4 for crushing plants?
A: Lower rotational speed reduces mechanical stress on bearings while maintaining adequate torque for medium-duty crushing.

Q2: How to mitigate dust in sand-making processes?
A: Wet suppression systems (+0.3% moisture content) or pulse-jet bag filters achieve <20mg/m³ emission standards.

Q3: What’s the typical lifespan of wear parts?
A: Mn18Cr2 jaw plates last ~120,000 tons in granite crushing; VSI rotors require refurbishment every 800–1,200 hours.

The industry continues evolving with hybrid power systems and AI-driven predictive maintenance reshaping traditional operational paradigms. Producers investing in technology-upgraded solutions like optimized motor-crusher pairings will lead in both efficiency and sustainability metrics.
