1 grinder, grinder open grading system, check to check whether there are metal objects and debris crushed in the room;

2. Check whether there are metal objects and sundries in the feeding hopper and feeding quality screw of the superfine pulverizer;

3. Check whether the fastener is tightened by the superfine grater;

4. Whether the tension of the super fine grinder transmission belt is moderate, and whether the protective cover has been installed;

5. Check the collision of transmission parts, analyze the reason if there is any, and eliminate it in time;

When turning the transmission parts, if there is any abnormal phenomenon, then move the parts and check whether the operation direction is correct;

① The top view of the clockwise rotation direction of the grinding disc;

②The feeding spiral structure should be right-handed in the length direction;

③ The rotation direction of the grading wheel, when viewed from above, is changed from clockwise to counterclockwise according to customer demand. The jet mill uses high-speed airflow to ultrafinely pulverize the material. It can be divided into disc type jet mill and ellipse jet mill. The ultrafine pulverizer uses air separation, heavy pressure grinding, and shearing to achieve ultrafine pulverization of dry materials. It is composed of cylindrical crushing chamber, grinding wheel, grinding rail, fan, material collection system and so on.

7. Run the super fine grinder without load for 20-30 minutes, observe the working current, temperature and vibration analysis: the temperature rise of the spindle bearing should not exceed 35°C, and the maximum target temperature should not exceed 70°C (the temperature of different environments is generally not greater than 40°C) ; The amplitude of the vibration signal of the machinery and equipment must not be too large. The super fine grinder uses air separation, heavy pressure grinding, and shearing to achieve ultrafine grinding of dry materials. It is composed of cylindrical crushing chamber, grinding wheel, grinding rail, fan, material collection system and so on. Feed production can only be started after the dry run develops normally.

8. The super fine grinder should properly open the upper and lower air doors of the gravity dust collector chamber.
