1. For newly installed equipment, when the equipment is in place and the bin to be crushed is connected, it is inevitable that foreign objects such as iron pieces, welding rod heads, and welding slag will remain. When the fan and the main motor are not turned on, open the impurity removal baffle under the material inlet to let the impurities and washing materials be discharged from here. After the completion, open the observation door of the super fine grinder to check whether there is any impurity in the crushing disc, and whether there is any hidden danger of collision between the hammer knife and the ring gear.

2. After the preliminary inspection is normal, turn on the power to start the equipment and check the rotation direction of all motors.

3. Check and set the parameters of the two inverters of the feeding motor and the grading wheel motor of the super fine grinder, and check whether the adjustment of the corresponding circuit breaker, contactor, thermal relay, and overcurrent relay of the motor is appropriate? Re-tighten all the primary threads.

4. Check whether the injection of the electromagnetic valve is normal and strong, and adjust the pulse width of the electromagnetic valve of the dust collector and the interval of injection.

5. Check whether there is any air leakage from the air lock under the brake dragon. You can put your hands or fine powder on the interface to see if there is any feeling of inhalation. If so, it must be sealed. After the above inspections are all normal, prepare to produce with materials.
