The ZSJ Double-Rotor Sand Making Machine, also known as a hammer-type sand maker, produces sand through hammer impact and counter-impact with crushing plates. The finished sand meets particle size distribution and fineness requirements for commercial concrete mixing plants.
Applicable Materials: Limestone, bluestone, and other medium-to-low hardness materials
Machine Type: Double-rotor / hammer-type sand making machine
Capacity: 20–280 T/H
Max Feed Size: ≤ 150 mm
The ZSJ twin-rotor casing opens from the rotor side and uses hydraulic ejection for opening, making it more convenient and faster to replace rotors, grates, and other components. This significantly improves work efficiency and reduces the labor intensity for maintenance workers.
The ZSJ double-rotor sand making machine uses the principles of hammer impact and impact plate crushing to produce sand, and is therefore also known as a hammer-type sand making machine.
Conact Us
The ZSJ double rotor sand making machine is used for producing manufactured sand and aggregate, especially for commercial concrete mixing plants. It can meet strict requirements for particle gradation and fineness modulus.
It is suitable for limestone, bluestone, and other medium-to-low hardness materials, making it ideal for quarrying and construction aggregate applications.
The machine uses two counter-rotating rotors. Material is repeatedly impacted by hammers and crushing plates, then collides at high speed between the two rotors, achieving efficient “stone-on-stone” crushing before being discharged through the grate gaps.
The double rotor structure improves crushing efficiency, increases output, and reduces wear on hammers and internal parts. It also produces well-shaped particles with continuous gradation and adjustable fineness.
Yes. The machine features a hydraulic opening system, inspection doors, and adjustable grate gaps, allowing fast replacement of rotors and wear parts, reduced downtime, and easier maintenance.
