The disc mill is also called a disc type steel mill. The following problems often occur during the milling process. 1, low production efficiency. The main reason is that the drive shaft speed is too low, power is not enough, the tape is too loose or a serious wear; the distance between the grinding plates is too small, affect the flow, should be adjusted to large spacing; grinding teeth become blunt, to deal with the position of static, dynamic grinding sheet, if Abrasive wear should be replaced with a serious one. The screening efficiency of the screening device should be low. The adjustment, cleaning and screening components should be checked. 2, high powder temperature, affect the quality of flour. The main reason is that the speed exceeds the rated index, resulting in large heat, so that the material temperature increases; too much feed and increase the load; the distance between the two grinding plates is too small and the power consumption increases, the material flow decreases, the material temperature increases; High water content, poor fluidity, and high power consumption. 3, silty rough, containing bran. The main reason is that the sieve is too thin or damaged, so that the bran is leaked into the powder; the gap between the discs is too small or the teeth are too sharp, so that the bran is ground into fine powder; the water content of the material is too low, and the drying is too dry. The skin is too fine and mixed in the powder; the material flow rate is too small and the grinded fineness is fine, but the bran eye may also be finely ground. 4, the bearing rotation is not flexible, the temperature increases. The main reason is that there are more dust in the bearing and affect the rotation; the transmission belt is too tight and causes bearing heating; the flow is too large, the disc clearance is too small, and the material moisture content is too high, causing excessive load of the machine, which leads to an increase in bearing temperature. And damage; bearing cover felt wear and failure, so that dust into the bearing, affecting the rotation and increase the temperature. 5, the machine vibrates seriously or has noise. The main reason is that the machine seat bolts and machine connection screws are loose; there are many impurities in the materials, such as iron blocks and sand grains, which cause abnormal noise in the work; the bearings are seriously worn and damaged, causing the spindle to jump and cause vibration of the entire machine and A murmur is emitted; the moving and static grinding discs cause noise.
