Introduction

Double Rotor Sand Maker

The Double Rotor Sand Maker is an advanced sand production machine that utilizes two synchronized high-speed rotors to achieve high crushing efficiency and excellent product quality. As materials enter the crushing chamber, they are subjected to repeated impact from both rotors, ensuring thorough crushing and improved particle shape. This dual-rotor system increases the material's contact frequency, reduces over-crushing, and significantly boosts output compared to single rotor models. With a compact structure, wear-resistant components, and easy maintenance, it is ideal for large-scale sand and aggregate production in industries such as construction, mining, road building, and cement manufacturing. Its ability to produce fine, consistent sand makes it a preferred choice for high-standard engineering applications.

Working Principle

Working Principle

The Double Rotor Sand Maker operates using two rotors rotating in opposite or same direction at high speed. When raw materials are fed into the crushing cavity, they are first struck by the upper rotor and then further impacted by the lower rotor. The dual-impact process creates intense crushing forces that break down the material into fine particles. This repeated collision, shearing, and grinding ensure high reduction ratios and excellent particle shape. The design minimizes unqualified material and increases crushing efficiency, making it especially suitable for producing fine sand from medium-hard rocks and construction waste.
