Raymond mill is designed with circulating air, not direct the wind. Therefore, to analyze machine powder collector pipes, powder collector pipe connections to the fan flange must be sealed very strict, can not have a gas leak. Powder collector spout position under pressure valve counterweight must be reasonable and may even discharge. If you are manually controlled, the boot must press down for about 5 minutes, powder collector when there are material slowly lifted, dust bag Raymond work in education must have been eaten bulging bag must To maintain high pressure grinding breathable, if airtight extreme pressure mill, Raymond mill will send shock. If the production process, not a sudden Raymond mill feed, then they would be under pressure valve lift up the powder collector. Another damper Raymond mill is strictly checked.
