What are the common faults of vortex milling machine
Date: 2025-09-02Read: 4
The common faults, causes, and solutions that may occur during the use of the vortex mill are as follows: -
Product granularity is too large
-
reasonLoosening of the V-belt leads to a decrease in transmission efficiency.
-
solutionTighten the V-belt and adjust the relevant components to the appropriate position.
-
Abnormal body vibration
-
reasonLoose components, loose bottom corner screw caps, or bent and deformed spindle.
-
solutionCheck and tighten all components, replace the deformed spindle, and readjust the balance.
-
Bearing cylinder locked
-
reasonExcessive heating of bearings, lack of oil or entry of dust, or damage to the bearings themselves.
-
solutionSuspend equipment rest, clean bearings and add oil, and replace damaged bearings in a timely manner.
-
excessive current
-
reasonThe suspended shaft sliding bearing is locked, causing oil sludge to accumulate in the cavity, or the gap between the air outlet is too large, resulting in dust entering.
-
solutionClean the oil sludge in the suspension shaft chamber, adjust the gap between the air outlet to prevent dust from entering.
-
Abnormal sound in the grinding chamber
-
reasonPoor lubrication of roller bearings can cause the rollers or grinding rings to break.
-
solutionStrengthen bearing lubrication and replace damaged rollers or grinding rings.
-
Abnormal wear of rollers and grinding rings
-
reasonThe connecting air duct of the suspended shaft oil chamber is worn through, and the powder erosion causes component wear.
-
solutionRepair or replace worn out air ducts to enhance equipment wear resistance.
-
No powder production or low powder production, low output
-
reasonPoor sealing of powder lock, wear of scraper blade, blockage of air duct or leakage of pipeline.
-
solutionAdjust the powder lock seal, replace the scraper, clean the air duct and seal the pipeline.
-
The finished powder is too coarse or too fine
-
reasonAnalyze blade wear or improper adjustment of fan airflow.
-
solutionReplace the blades of the analyzer and adjust the air intake of the fan to a suitable range.
-
The host current rises and the machine temperature is too high
-
reasonExcessive feeding can cause blockage of the air duct, or poor exhaust of the pipeline can lead to heating of the circulating airflow.
-
solutionReduce the feeding amount, clean up the powder accumulation in the air duct, and open the air duct valve to lower the machine temperature.
-
Fan vibration
-
reasonPowder accumulation or uneven wear of the fan blades, or loose anchor bolts.
-
solutionClean or replace the fan blades, tighten the foundation bolts to stabilize the equipment.
-
Grinding roller device powder feeding causes bearing damage
-
reasonCut off oil, damaged sealing ring, or long-term lack of maintenance and cleaning.
-
solutionTimely refueling and maintenance, regular cleaning of equipment and replacement of sealing rings.
-
Transmission device and analysis machine oil tank heating
-
reasonExcessive viscosity of the engine oil or malfunction of the threaded pump oil can cause a lack of oil in the upper bearing.
-
solutionCheck the engine oil grade and viscosity, and confirm whether the analysis machine is running in the correct direction.
-
The bearing of the grinding roller assembly is damaged
-
reasonOil seal damage, loose screws, or fatigue damage to bearings.
-
solutionRegularly check the oil seal, tighten screws, and replace fatigue bearings.
-
Grinding machine "full grinding"
-
reasonExcessive feeding amount, excessive moisture content in materials, or improper grading of steel balls.
-
solutionAdjust the feeding amount, control the moisture content of the material, optimize the grading of steel balls to improve the efficiency of the mill.
-
Machine abnormal noise
-
reasonLoose parts or foreign objects entering the interior of the equipment.
-
solutionTighten loose parts and stop the machine to clean internal foreign objects to ensure safe operation of the equipment.
