Analysis of abnormal causes of Raymond mill powder output!

Raymond mill features three-dimensional structure, small footprint, complete set of strong, from block material to finished flour independent independent production system. The fineness and fineness of finished flour are difficult to meet with other milling equipment. The mechanical transmission device adopts a closed gear box and belt pulley, which has stable transmission and reliable operation. The important parts of Raymond mill are made of high quality steel and wear resistant parts with high performance wear resistant materials. The machine has high wear resistance and reliable operation. The centralized control is adopted in the electric system, and the mill can basically realize unmanned operation and maintenance.

 

The working principle Raymond mill breaks the bulk raw material into the required feed grain size, the material is transported to the storage bin by the bucket elevator, then the electromagnetic vibrating feeder is evenly sent to the grinding chamber of the main engine, and the material into the grinding cavity is grinded between the grinding roller and the grinding ring, and the powder after the powder mill is carried to the analysis by the airflow of the fan.

 

Common fault one: fan vibration. It is caused by unbalance of powder or wear on the wind blade. The anchor bolts are loose. Removal of the blade to clean up the powder or change the blade. Tighten the anchor bolts.

 

Common failure two: grinding roller device into powder bearing cup. Long term lack of maintenance and cleaning. The method of removal will be refueling in time according to the prescribed time. Regular cleaning and replacement of oil seal.

 

Common faults three: Raymond mill does not produce powder or powder, and the output is low. The reason is that the powder lock is not adjusted well, and the seal is not strict. The scraper is worn out and the material can not be shoveled. The method of checking and adjusting the sealing of the powder lock is checked and adjusted. Replace the new shovel.

 

Raymond mill common fault four: finished flour is too thick or too thin. Cause analysis of mill blade wear is serious, can not play a role in grading. The wind rate of the fan is not appropriate. The method of elimination is to replace the blade, and the air intake volume of the small fan is too thick. The imported air volume should be improved.

 

Raymond mill common fault five: the main engine noise is large and has a larger vibration. The reason is that the feed quantity is small. Five ensure that the Raymond mill feed is uniform and continuous, and the abrasion of the blade is serious. The impact of the material is hard or the grind ring of the material layer is seriously deformed. The adjustment method is to adjust the feed amount of Raymond mill and replace the new blade to replace the feed size. Replace the roller mill ring.
