Product Description
Compact Laboratory Rock Crusher
High-efficiency laboratory crushing machine with adjustable settings for controlled particle size, suitable for crushing rocks and minerals.
Product Overview
The SZΦ250 Laboratory Double Roll Crusher is a precision-engineered laboratory crushing machine developed for mineral sample preparation. It features two precision-machined alloy steel rollers that rotate in opposite directions to crush materials into uniform particle sizes.
The machine adopts a compact structure with an enclosed crushing chamber to reduce dust generation during operation. Its adjustable discharge gap allows precise control of final particle size according to laboratory testing requirements.
With stable performance, easy maintenance, and low operating noise, this crusher is widely used before grinding, flotation testing, chemical analysis, XRF/XRD analysis, and mineral processing research.

Safety Operation Instructions
To ensure safe operation and extend the service life of the equipment, please follow these safety instructions:
  1. Qualified Operators: Only trained personnel should operate the machine. Operators must carefully read and understand the instruction manual before use.
  2. Never Service While Running: Do not adjust, clean, lubricate, or repair the machine while it is operating. Always switch off the power supply and wait until all moving parts have completely stopped before performing any maintenance.
  3. Proper Electrical Protection: The machine must be properly grounded. Electrical cables should be installed in insulated conduits. It is recommended to install a residual current device (RCD) or leakage protection device according to the operating environment.
  4. Overload Protection: To prevent motor overheating or equipment damage caused by overloading, an overcurrent protection device should be installed based on the operating frequency and the characteristics of the processed materials.
  5. Inspect Safety Devices: Before each operation, check that all electrical protection devices, safety guards, and protective covers are in good condition and functioning properly. Any potential hazards must be eliminated before starting the machine.
