What is a Rock Sand Making Machine?

A rock sand making machine, also known as a vertical shaft impact (VSI) crusher, is specialized equipment designed to crush hard rocks (e.g., granite, basalt) into artificially manufactured sand with precise particle sizes. It is widely used in construction, highways, and concrete production to replace natural sand.

Models of Rock Sand Making Machines

Common models include:

  1. Rotor-Centric VSI Crushers: High-speed rotor design for fine crushing (e.g., 200-500 t/h capacity).

  2. Centrifugal Crushers: Utilize centrifugal force to shape sand particles (e.g., 100-300 t/h capacity).

  3. Mobile Sand Making Plants: Portable units for on-site processing (e.g., 50-200 t/h capacity).

Key Features

  • High Efficiency: Optimized crushing cavity design ensures 30-50% higher output than conventional crushers.

  • Adjustable Particle Size: Output sand fineness modulus (2.6-3.0) can be customized via rotor speed adjustments.

  • Low Wear: Tungsten carbide or ceramic wear-resistant parts extend service life by 40%.

  • Energy Saving: Hydraulic or electric drive systems reduce power consumption by 15-20%.

Suitable Raw Materials

It processes hard rocks (granite, basalt, river pebbles), limestone, iron ore, and construction waste (concrete chunks, bricks). Moisture content should be <5% to prevent clogging.

Working Principle

Rocks enter the high-speed rotating rotor through the feed hopper and are accelerated to 60-80 m/s. They collide with the surrounding anvil ring or rock-lined chamber, achieving “rock-on-rock” or “rock-on-iron” crushing. Shaped sand particles are screened via a vibrating screen to meet size standards.

Usage Precautions

  • Pre-Operation Inspection: Check wear parts (rotor, anvil) and lubrication system every 8 hours.

  • Feed Control: Avoid over-size rocks (>5cm) or metal impurities to prevent rotor imbalance.

  • Dust Management: Use water spray or dust covers in dry environments to maintain air quality.

  • Maintenance: Replace wear parts in batches every 500-800 hours of operation.
