1. Production Line Overview

Potassium-sodium feldspar, a critical raw material for the ceramic industry, requires processing that ensures high purity and uniform particle shape. This crushing line combines impact crushers and sand-making machines with a sunken-site design to achieve high efficiencyeco-friendliness, and low-cost mass production, providing reliable raw materials for high-quality ceramic manufacturing.

Applications: Ceramic raw material preparation, construction aggregate processing.
Feed Size: ≤700 mm
Output Products: 0–5 mm, 5–10 mm, and other specifications tailored to ceramic production needs.
Future Direction: Ongoing upgrades aim for lower energy consumption and higher automation, supporting the ceramic industry’s green transition.


2. Core Equipment Configuration

① Impact Crusher

  • Role: Medium/fine crushing core.
  • Principle: Uses impact force from high-speed rotating blow bars for multi-stage crushing and grinding.
  • Features:
    • Modular design enables quick wear-part replacement.
    • Hydraulic opening mechanism reduces maintenance time by 40%.
    • Capacity: 100–300 t/h.
    • Output: Cubical particles with <5% flakiness, ideal for ceramic raw materials.

② Sand-Making Machine (VSI Crusher)

  • Principle: Combines “rock-on-rock” and “rock-on-iron” modes for precision crushing.
  • Case Study: A 300 t/h line in Jiangxi, China, achieved:
    • Stable fineness modulus: 2.6–3.0.
    • Powder content: ≤3%, meeting premium ceramic body standards.
  • Automation: Real-time speed and feed adjustment ensures consistent particle size.

3. Sunken-Site Design Advantages

By installing equipment 3–5 m below ground level in a terraced layout, the design leverages gravity-fed material flow, reducing conveyor length by 30% versus flat layouts.

Key Benefits:

  • Dust Control: Enclosed tunnels limit dust to <8 mg/m³.
  • Noise Reduction: Boundary noise ≤65 dB.
  • Space Savings: 25% less land use, ideal for compact ceramic industrial parks.

4. Equipment Advantages

✔ High Efficiency & Low Energy Use:

  • 20% higher crushing efficiency vs. traditional setups.
  • Energy consumption: 8–10 kWh/t.

✔ Smart Control:

  • Automated systems adjust parameters in real time.
  • Remote monitoring and fault alerts.

✔ Eco-Compliance:

  • Sealed tunnels + pulse dust collectors (>99% efficiency).
  • Noise suppression meets regulations.

✔ Flexibility:

  • Modular wear parts for quick swaps.
  • Adjustable parameters for varied material needs.

Client Feedback

“The VSI crusher’s 0–5mm premium sand fully replaces natural quartz sand, with iron content <0.15%. Hydraulic maintenance cuts downtime to 2 hours/month, and 95% operational stability makes this a benchmark project for local ceramic supply.”
