Application

Sand and gravel quarry, mining, concrete mixing station and other industries.

Applicable Materials

Limestone, bluestone, coal gangue, shale, gravel, etc.

Working Principle

The double rotor sand making machine is mainly composed of a main body, a crushing plate, an upper rotor, a lower rotor, a pendulum, and a rotary drive device.

Driven by dual motors, two sets of rotors connected in series rotate at high speed at the same time. After the materials are crushed by the superior rotor in the inner chamber of the machine, then which will be immediately finely crushed by the hammer head of the rapidly rotating lower rotor. The materials in the inner chamber collide rapidly with each other, crushing each other, achieving the effect of powders. Through repeated cycles, the finished materials with qualified particle size are discharged through the grate controlled discharge port.

Features of Double Rotor Sand Making Machine

1.The double-rotor structure has more kinetic energy with larger capacity.

2. The double rotor sand making machine is equipped with observation doors, which is convenient to observe the internal working condition. The full hydraulic opening, quick and convenient replacement and maintenance of internal parts.

3. The rotor is equipped with a high manganese and high chromium protective cover, which increases the lifespan by 30%;

4. The hammer shaft hole is equipped with a tungsten alloy steel sleeve, which is wear-resistant and impact-resistant.

5.The grate bar can be customized according to the users’ needs. The gap between the grate bar and the hammer head can be adjusted flexibly, which fully ensures the crushing efficiency of the hammer head.

6.The finished sand shape is cubic, and the fineness modulus is adjustable.
