Fine rock infinitely variable speed grinding machine

M-280型Fine rock infinitely variable speed grinding machine

The M-280 automatic grinding machine is the main equipment used by research institutions such as petroleum, geology, metallurgy, and chemical engineering to produce rock and mineral flakes. The grinding process of this machine is manually operated, and the thickness of the rock pieces can be freely controlled manually. During fine grinding, the rock pieces can be finely processed to between 0.15 and 0.08mm, and then manually processed to produce standard pieces with a thickness of 0.03mm. The machine features: small size, strong mechanical rigidity, beautiful appearance, low noise, adjustable speed, and smooth operation. Appropriately increase the speed, use diamond sand instead, and it can also be used as a medium grinding machine. 2、 Main technical parameters: 1. Power supply: 50Hz 380V ± 5%; 2. Power consumption: 1.2Kw DC motor; 3. Grinding disc speed: stepless speed regulation within the range of 0-800 revolutions per minute; 4. Use diamond sand: medium grinding 320 #, fine grinding 800 # or 7 #; 5. Production specifications: 25 × 25, 25 × 32; 6. Grinding thickness: 0.20-0.10mm for medium grinding and 0.15-0.08mm for fine grinding; 7. Environmental temperature: 0 ℃ -40 ℃ (subject to adhesive); 8. Chassis: length x width x height 800 x 460 x 680; 9. Weight: 90kg. 3、 The working principle and block diagram of the machine consist of three parts: transmission system, frame, and electronic control circuit. The transmission adopts an A-type V-belt, which is variable speed through a speed controller, and is positioned by a positioning shaft, a pin, and four rigid balls. Grinding disc pressure manual control. The speed change is controlled by a frequency converter and can be continuously adjusted without changing the motor torque (see DC speed regulation manual for details). Box diagram: 4. Instructions for use: 1. The user must be familiar with the instructions and precautions in this manual before using the machine. 2. Turn on the power switch and the indicator light will turn on. Preheat for 5-10 minutes (during preheating, the motor will start rotating. You can press the "stop" button once to stop the rotation of the motor). 3. Free control of thickness
