1. The Calcium Carbonate Grinding Machine does not produce powder or has low output.
First of all, the lack of powder and low output means that the machine is normal before, and suddenly there is no powder. Under normal circumstances, such reasons include: pipeline leakage or blockage; lock valve failure; excessive feed; pipe system installation is too long and too high, elbow too much angle at the bend is too small; grinding roller device card Dead does not turn; the blade wears more or is too wet.
Treatment plan: Check if the powder valve and the air locker are stuck or open, and block the air leakage of the pipe and the valve of the air check door. Check if the roller unit is stuck and the blade is worn. Change the height of the pipe and increase the angle at the elbow. At the same time, the feed amount should be controlled below 6%.
2. The finished powder of the Calcium Carbonate Grinding Machine is too thick or too fine.
The reasons for the analysis include: analysis of the mill blade wear is serious, can not afford the classification; the fan air volume is not properly controlled.
Treatment method: replace the blade to properly close the small fan inlet air volume to solve the rough phenomenon; adjust the inlet air volume.
3, Calcium Carbonate Grinding Machine host shutdown frequently, and the machine temperature is too high
The reasons for this situation include: too much material in the machine, too little powder, the temperature of the mill rises, the current of the blower is lowered, the valve of the residual air duct is closed, and the hot air cannot be discharged.
Solution: Remove the accumulated powder in the return air box and the pipe, and evenly feed. Also check that the adjustment of the relay is lower than the rated current of the click.
4, the Calcium Carbonate Grinding Machine host noise is large with a large vibration
Cause: Normally, the deviation between the main reducer and the coupling is large, the anchor screw is loose, and the one-way thrust bearing on the main unit is disengaged up and down during assembly. When there is no gap in the middle of the coupling, the thrust bearing will be topped. From the material; the material is too hard, the powder is like powder or the feed is too little; or the foundation is not strong.
Treatment method: Find the center, and the difference between the two couplings is guaranteed to be 0.30mm or less. Adjust the coupling clearance to about 5mm. If the abrasive is powdered, reduce the main engine speed to 110 - 120r/min; tighten the anchor screws and all fasteners.
5, Calcium Carbonate Grinding Machine blower vibration
The reasons for the analysis include: accumulation of powder or wear on the blades; loose anchor bolts.
The solution is to remove the blade from the powder or replace the blade industry; tighten the anchor bolts.
6, reducer and analysis machine fever
The reasons for the analysis include: no gap due to the assembly of the upper and lower bearings; the viscosity of the oil is large, the upper bearing is short of oil; the oil is added too much, it is not easy to dissipate heat; the air filter is installed and leaked, and the pipe joint is blocked. Protection, so that dust enters the oil pool from under the turntable.
The solution is to adjust the bearing clearance in the range of 0.15 - 0.20mm. Check the viscosity of the oil to keep the oil viscosity moderate.
7, the grinding roller device into the powder bearing damage cup
Reasons for the analysis: The main consideration is that the upper and lower bearing gaps are large, and the grinding roller shaft is easy to shake during operation, causing the seal ring to wear and the powder to enter the bearing, which accelerates the wear of the bearing, makes the gap larger, and presents a vicious circle. During operation, the two nuts on the upper part of the grinding roller are loose, causing the gap between the upper and lower bearings to increase, causing powder and oil to break, and accelerating the wear of the bearing.
The solution is to refuel in time according to the specified time; clean regularly and replace the oil sealer.
