Usual breakdowns of and solutions to Raymond mill...

Raymond mill common fault 1: the temperatures of the transmission device and analytical engine and the fuel tank are rising.

Reason: (1) Engine oil has high viscosity and the oil layer is thick, the screw pump oil can not be added on the upper bearings so the bearings are lack of oils.

Processing method: (1) Checking the oil grades and viscosity to see whether the oil meet the requirements. (2) Checking the running direction of analysis machine.

Raymond mill common fault 2: the powder comes into the grinding rod, the bearings are broken.

Reason: (1) The oil is not enough, or the seal ring is broken. (2) Long-term lack of maintenance and cleaning

Processing method: (1)According to the stipulated time, the oil should be added timely. (2)Regular cleaning, replace the oil seal.

Raymond mill common fault 3: main engine will produce large noise and there is large vibration.

Reason: (1)The feeding material is less, shovel knife is seriously worn, anchor bolt is looseness. Vibration feeder. (2) the materials are hard and have large impact, or there is the materials layer without materials. (3) Grinding roll and grinding ring are not rounded are serious deformation. mobile crusher.

processing method: (1) Adjusting the amount of feeding materials in raymond mill and replace new shovel knife. (2) Replacing the feeding grain size. (3) Replacing the grinding rod and grinding ring.

Raymond mill common fault 4: the electric current in raymond mill main engine is rising, machine temperature is rising by the heated circulating air, machine temperature is rising,

fan current is declining, jaw crusher.

Reason: (1) The feeding material is excessive, air channel is blocked by powder, pipe exhaust not free, cycle airstream fever that Lord of the current, high temperature of the machine, fan current decline jaw grinder.

processing method: (1) Reducing charging rate, clearing accumulated powder in air channel (2) Opening valves of the air hoses, the fed materials temperature should be controlled to under 6℃.

Raymond mill common fault 5: draught fan vibrating.

Reason: (1) there is accumulated powder on the fan blades or the blades are seriously worn.(2) anchor bolt is looseness.

Processing method: (1)Clearing accumulated powder on the fan blades, or replacing the fan blades. (2)Tightening the anchor bolts.

Raymond mill fault treatment and solution 6: the raymond mill does not make powder out, or the powder amount is less, or low yield

Reason: (1)The powder lock is not adjusted into a good condition and the seal imprecision, causing powder pour absorpt into cement plant equipment; (2) Shovel knife is seriously worn and the materials can be fully ground.

processing method: (1) checking and adjusting the powder lock, the air leakage place should be sealed up. (2) Replacing new shovel knife.

Raymond mill fault 7: Finished product powder is too thick or too thin

Reason: (1) The blades of raymond mill are seriously worn and cannot afford grading role. (2) Fan delivery is not suitable.

Processing method: (1) changing the blades, turning down the draught fan.(2)If the powder is too fine, improve the fan delivery.
