12 kinds of Raymond mill common problems and solutions!

Causes : 1) The powder of the mill is too thick or the wear is unbalanced; 2) The grounding bolt is loose.

Solution : 1) Clean up the powder on the fan blade or replace the blade of the blade; 2) Tighten the anchor bolt.

Causes : 1) the grinding roller does not rotate or the grinding ring is loose; 2) the inside of the machine enters the metal object; 3) the feeding is uneven or the feeding is small; 4) the two halves of the coupling are different axes; 5) the grinding roller wears, Deformation is out of round; 6) raw materials are too strong or too large; 7) the foundation is not strong.

Solution : 1) remove and repair the grinding roller device or tighten the grinding ring; 2) check whether there is metal object falling and clear inside; 3) adjust the feeding amount; 4) need to align the coaxiality of the shaft joint; 5) timely Check and replace the grinding roller; 6) replace the raw materials; 7) reinforce the foundation.

Causes : 1) The discharge valve (locker) is not closed semi-closed, the outside air and dust are sucked up; 2) the main air duct is blocked; 3) the blade is worn, causing too little scrap or failing to shovel; 4) There is a serious leak in the pipe and flange connections.

Solution : 1) repair or seal the discharge valve; 2) remove the blockage; 3) check the blade wear and replace the blade; 4) carefully check the leak to re-seal.

Causes : 1) The speed of the classifier does not match the graded particle size required for the material; 2) The air volume of the blower is not appropriate. 3) The grader blade is worn (too thick).

Solution : 1) adjust the speed of the classifier; 2) if the powder is too thick, when the speed of the classifier is not reached, the blower valve of the small blower can be properly closed; if the powder is too fine, the speed of the classifier can be reduced. Or remove the classifier to increase the blower speed. 3) Blade wear will result in coarse powder and new blades will need to be replaced.

Causes : 1) Feeding speed is too fast; 2) The air duct is blocked by powder and the duct is not exhausted.

Solution : 1) Reduce the amount of feed, 2) Remove the accumulated powder at the air passage or open the large air duct valve, and control the temperature of the feed port to below 6 degrees.

Causes : 1) The viscosity of the oil is too thick; 2) The direction of the analysis machine is not correct.

Solution : 1) Check if the viscosity of the oil meets the requirements; 2) Adjust the running direction of the analyzer.

Causes : 1) insufficient power distribution; 2) unstable voltage.

Solution : 1) Check whether the motor meets the power of the mill and replace it for the motor power; 2) Check the power line and set up the voltage regulator.

Causes : 1) Foreign matter such as iron blocks enters; 2) The material is fed too much or the feed is not uniform.

Solution : 1) Check if foreign matter enters and removes; 2) Uniform feeding, the material hardness is controlled within an appropriate range.

Cause : There is a gap between the main unit casing and the edge of the grinding disc.

Solution : Design the recycling device or the leakage device, or extend the distance between the outer edge of the bed and the outer edge of the plate, or increase the height of the baffle.

Causes : 1) The bearing is seriously worn; 2) The lubrication effect inside the bearing is poor, and the amount of internal dust is large, causing the lock.

Solution : 1) Replace the new bearing; 2) Clean the debris in the bearing, add new lubricant after cleaning, and strengthen the bearing seal protection measures.

Causes : 1) accumulated powder or wear imbalance on the blades; 2) loose anchor bolts.

Solution : 1) Remove the powder from the blade or replace the blade; 2) Tighten the anchor bolt.

Causes : 1) The valve status of the pipeline is abnormal; 2) The dust of the bag filter is excessive.

Solution : 1) Check all valve status of the conveying pipe and adjust to the correct position; 2) Clean the bag filter to keep the dust removal device unblocked.
