Powder Mill common problems and solutions in the production process

Mill equipment in the production process will inevitably be this or that problem, fault. And how fast, accurate troubleshooting to improve production efficiency of Powder Mill is a critical role. The following micro-grinding Zhengzhou Tin Shui expert interpretation of some common faults and troubleshooting Powder Mill for us in detail. 1, the powder raymond mill hosts noisy and have greater vibration Cause: (1) a small amount of feed. Blade badly worn shovel afford material, anchor bolts loose. (2) expected large hard impact, or no material material layer (3) roller mill ring round loss seriously deformed. Solution: (1) adjusting the feeding amount, replacement blade. (2) replacement of feed size. (3) the replacement of mill roller, grinding ring. 2, fan vibration Cause: (1) on the blades or wear powder accumulated imbalances. (2) anchor bolts loose. Solution: (1) removal of leaves accumulated powder or replace the blade. (2) tighten the anchor bolts. 3, powder mill gearing and analyze heating oil tank Cause: (1) the oil viscosity giant thick, threaded pump oil hit up the upper bearing short of oil. Solution: (1) Check the oil grade and viscosity is consistent with the requirements. (2) checking of machine running direction 4, powder mill roller device into the powder bearing damage Cause: (1) off the oil, or seal damage. (2) Long-term lack of maintenance and cleaning. Solution: (1) the time required to timely refueling. (2) regular cleaning, replacement of seals. 5, no powder or a micro-grinding flour yield less Cause: (1) The lock powder device is not adjusted, Mifengbuyan, resulting powder suck. (2) blade wear and material shovel can not afford. (3) duct blockage (4) pipe leak sealed well. Solution: (1) examine and adjust lock seal powder was found to be leaking at the blade. (2) replacement of the blade. (3) After the duct material to clean up and re-cutting. (4) sealing the pipe. 6, finished powder too thick or too thin Cause: (1) analysis of blade wear serious, can not afford grading effect. (2) inadequate fan capacity. Solution: (1) Replace the blade length appropriate small wind turbine into the wind off too coarse to resolve. (2) too small and should be increased imports of wind mills. 7. Powder Mill hosts the current rise, machine temperature rise, fan current decline Cause: (1) feeding excess powder duct is clogged, poor exhaust pipes, circulating air heat so that the main current, machine temperature rise, the fan current decreases. Solution: (1) reducing the amount of feed, remove duct accumulated powder. (2) On Dayu duct valve, into the machine the material temperature at below 6 ℃
