Materials fall into the gap between two rollers through the feeding inlet and are crushed by the extruding force of counter-rotating rollers. Finished products fall down naturally.
When encountering excessively hard or uncrushable materials, the rollers automatically retract under spring force to enlarge the gap. Hard materials fall off accordingly, protecting the machine from damage.
A negative pressure dust collection device can be installed at the discharge port to prevent dust when the machine is used alone.
Direct motor connection, strong transmission capacity, 5% higher efficiency than belt drive. No belts or belt covers required.
Low noise, simple structure and easy maintenance.
Adjustable discharge particle size, simple and clear gap adjustment. High practicability to meet diverse customer requirements.
All material contact surfaces are non-metallic, preventing metal contamination.
First application of silicon nitride ceramic rollers!
First adopted in granular silicon production!
Independently developed technology by Renovator Technology, serving new energy and electronic materials markets!
Built-in water cooling channels inside the roller. Cooling water flows to remove heat and prevent equipment overheating.
Suitable for temperature-sensitive materials such as lithium battery raw materials, avoiding performance degradation caused by high temperature.
Effectively controls roller temperature, reduces thermal stress and wear, and prolongs equipment service life.
Small footprint, compact structure and flexible layout, making full use of production space.
Easy for quick deployment and flexible configuration to meet requirements of different production lines.
Upper layer: mosaic roller or grooved roller; Lower layer: flat roller.
Power transmission via tooth meshing, avoiding slipping of traditional belt drive.
Optimized roller surface structure ensures full material crushing and higher output.
