Feed mouth material back spray(Hammer Mill)

Pulverizer inlet material back spray, you can check from the following aspects:

01

Check the wind network system

(Hammer Mill)

The wind network system should be stopped after the pulverizer stops, for example, after the pulverizer stops, the dust collector is recommended to run for a period of time before stopping (it is recommended that the pulverizer stops at least 5 minutes before stopping the wind network system);

02

Check the guide plate and rotor direction(Hammer Mill)

Guide plate and the direction of rotation of the pulverizer motor (rotor direction) is not consistent, the production of each shift to adjust the steering, you need to ensure that the guide plate and the direction of rotation of the motor is consistent;

03

Inspection of dust collector(Hammer Mill)

Check whether the pulse bag paste and blowing whether the normal work, daily production needs to regularly clean the bag, blowing leakage attention to the replacement of the appropriate accessories;

04

Check the fan(Hammer Mill)

Check the fan damper opening, if the air volume is not enough, can be adjusted; normal fan running current is rated at about 90%, if it is not reached, to check the wind net;

05

Check the sieve (Hammer Mill)

The screen holes of the pulverizer are clogged, need to clean the screen or replace the screen.

WORK SUMMARY

2024 Taking New Steps Toward Effectiveness

Two Pulverizer vibration (Hammer Mill)

The pulverizer vibrates greatly when running, you can check from the following aspects:

01 Check the hammer blade and other accessories(Hammer Mill)

Hammer blade and pin wear is serious, need to replace a full set of new hammer blade and pin (hammer blade replacement need to pay attention to the counterweight);

02 check pulverizer bearings(Hammer Mill)

Crusher bearing damage, need to replace the new bearing, and do a good job of maintenance, bearing clearance adjustment is best 6-7 silk, every time you install the bearings need to check;

03 Check the pulverizer spindle(Hammer Mill)

Check the main shaft of the pulverizer, such as bending deformation, need to straighten or replace the new shaft;

04 Check the pulverizer coupling(Hammer Mill)

Pulverizer coupling is not centered, need to re-adjust;

05 Check the pulverizer rotor (Hammer Mill)

Pulverizer rotor imbalance, need to check the rotor dynamic balance, judgment: such as the removal of all the hammer blades, pulverizer operation or vibration, indicating that the dynamic balance of the rotor has a problem, need to re-do the dynamic balance.

06 Check the installation of the pulverizer(Hammer Mill)

Pulverizer installation location is not right (such as not installed in the main beam of the plant), long-time operation caused by the common vibration, while the installation of attention to the super level.
