Superfine grinder winter maintenance precautions!

August 14, 2020

In the winter, the maintenance of the superfine pulverizer will also change according to the season. The low temperature is the most prominent feature, and the operation characteristics of the ultrafine pulverizer under the low temperature environment are appropriately adjusted.

Superfine grinder winter maintenance and precautions:

1. In the production process, the ultra-fine pulverizer must check the temperature rise of the bearing frequently. When the temperature rise exceeds 50 °C, it should be stopped and checked to find out the cause and eliminate the fault.

2. When the new machine is running, the transmission belt is easy to stretch. Pay attention to adjust the proper tightness of the belt to ensure the working life of the belt.

3. The wearing parts of the ultra-fine pulverizer should be inspected frequently and replaced in time to ensure the production quality and production volume.

4, ultra-fine pulverizer blades, liners should always check the wear and tear, if worn, the productivity is reduced, the particle size becomes thicker and found to be replaced after wear.

5, superfine pulverizer main machine and graded flow bearings are greased, using No. 2 special grease, degree 265-295.

6. The grease replacement period of the superfine pulverizer bearing is 2000 hours. The filling amount of grease is 1/2 (upper measurement) or 3/4 (down measurement) in the bearing cavity. Do not fill the grease too much. Will cause the bearing temperature to be too high.

7. The superfine pulverizer screw feeder has a fat-changing period of 4000 hours, plus ordinary calcium-based grease.


1. Output shaft e, that is, pulley e, to avoid slamming with heavy hammer and damaging parts.

2. It is strictly forbidden to turn the handle of the handwheel during the stop.

3. The lubricating oil used in the superfine grinder speed governor adopts N32 alkaline high-zinc type anti-friction hydraulic oil. The reducer uses 401 universal lubricating oil. It can not be replaced by other machines.

4. After using the ultra-fine pulverizer for 3,000 hours, replace the oil with new oil, then change the oil for the second time after 500 hours of use, and then use it for 1000 hours later. The ultrafine pulverizer is sensitive to temperature compared to other types of pulverizers, so use it carefully in winter, but the reduction in ambient temperature will also play a good role in the operation of the ultrafine pulverizer. The machine itself and the temperature of the material will rise. Will be low, more conducive to crushing some heat sensitive materials!
