In order to ensure the material quality and yield of Raymond mill , not only to consider the key to the material grain size, hardness, moisture conditions, the amount of feed that can not be ignored, Zhengzhou Lei mechanical technicians now summarize for you according to which to adjust the volume of feed to achieve the best utilization rate.
According to the changes in the grinding sound adjustment
In order to judge the work of the mill , the operator should always listen to the grinding sound or grinding sound is detected, especially in the first positions of the grinding sound (the operator to listen to the grinding sound when standing on the landing of the grinding media side). Material nature and structure type grinding different grinding sound is also different. But for a Taiwan Raymond mill, the basic stability of the material nature, the grinding sound is there are certain rules to follow.
Normal operation of the mill, a warehouse sound is clear and loud, "Dada" sound of ball impact, but there are slight impact sound. Finely ground positions "imperfections," the grinding sound of the grinding media. The material came from a voice, weak voice of materials for a long time. When the first positions of the sound weaker nausea, feeding too much, or particle size is too large, failed to timely adjust the volume of feed may also be material moisture content is too large compartment board fence hole sticky material, which results due to human rights poor nesting. If the sound is too strong, indicating that the material too small mill, according to Raymond grinding sound changes appropriately increase or decrease the volume of feed, and gradually the normal grinding sound adjustment.
According to the mill product fineness adjusted for changes in the volume of feed
Open Raymond machine , change when the granularity of the material into the mill, water, grindability and so the end product thicken, indicating that feeding too much; product variant sewing, show that the feed is too small; for a closed-circuit system, the general control of the grinding fineness in 0.08mm square hole sieve more than 30% to 40% back to the material in above 65% and 70%, when a grinding fineness control indicators substandard product fineness requirements in a timely manner to adjust the selected objects across the machine wind board or blades.
The application of "electronic ear" monitoring grinding tone control feeding
Operators are generally not sensitive enough ears to judge grinding sound, and the impact of noise on the human body. "Electronic ear" can be used to monitor the grinding sound, well according to the milling equipment to grind the tone changes to adjust the volume of feed.
