Particle size of the abrasive particles is, the size of a particle numerals.
GB provides two kinds of abrasive powder particle size and number.
Generally speaking, use coarse abrasive coarse (size number smaller), double disc grinding to a smaller (larger particle number); powder used formachine grinding and other precision machining and ultra-precision machining.
Powder Machine Grinding is often able to use a processing plant ore milling machine, it has a compact model, simple structure, yield superior, easy maintenance, energy-saving environmental protection and many other advantages. Because of its modern control system so that the whole process becomes more convenient powder. However, the new grinding machine during use may be due to improper operation or maintenance technician is not timely prone to mechanical failure of this or that, following a brief on some common faults powder grinding machine to do the next simple analysis. 1 motor failure The main powder grinding machine main motor power sources commonly used for large-scale production of energy-saving motors work, but the work environment is more severe because the equipment, and some users need to work 24 hours on the machine, which will undoubtedly bring great loss to the motor. Usually we recommend mechanical equipment work more than ten hours later to stop once, in addition to the equipment necessary to cool the dust outside, but also on other parts thorough overhaul and take preventive measures. (2) blocking powder Blocking powder grinding machine is also more common, the main reason is the user processing the material is too wet. Powder is too moist, adhesion increases, easily absorbed in the row of pink near the mouth caused finished film does not go out, cause equipment blockage, severely affecting the yield, so if the material moisture content is too high, then the best materials using first water discharge drying equipment, etc. grinding standards achieved during further processing. 3 high bearing temperature Grinding machine which has many important bearing mouth, but because of equipment, poor working environment, so the bearing seal is not good, then it is easy to get into the dust, which is likely to cause a short mill bearing temperature, and is likely to cause damage to components . Therefore, using the process in addition to bearing lubrication to ensure the normal outside work should pay great attention to sealing dust, high temperature should be timely if it is found to make a deal. Here is a brief analysis of the points of common technical failure grinding machine, grinding machine if you are using the phenomenon appeared above points, you should immediately make timely treatment, to bring you to avoid unnecessary damage to property.
