Floor shot blasting machine is a mechanical device used to clean, roughen, strengthen, or prepare floor surfaces. It works by accelerating steel shots through a high-speed blasting wheel, hitting the floor surface, and then automatically recovering the shots, dust, and debris.
Floor Shot Blasting Machine Daily Maintenance Methods
For ensuring stable performance and long service life of the floor shot blasting machine, daily maintenance work is very important. In actual site operation, many failures are caused by lack of simple daily checking.
1. Check Wear Parts Condition Daily
The blasting machine has high-speed rotating components and continuous abrasive impact. Therefore, wear parts should be checked every day.
- Check blast wheel blades, control cage, and impeller for abnormal wear.
- Observe if there is vibration, noise, or uneven blasting result, which usually means wear is already heavy.
- If wear reaches limit, replace immediately to avoid secondary damage.
2. Inspect the Shot Abrasive Flow
The quantity and quality of steel shots directly affect cleaning result.
- Make sure abrasive valve is opening smoothly.
- Check if abrasive inside the hopper is enough; if level is too low, add immediately.
- Remove foreign objects mixed into abrasive to prevent jamming of blast wheel.
3. Clean Dust Collector and Filter Elements
The dust collector is key for environmental protection and machine stability.
- Clean the filter cartridge or filter bag every day.
- Check the pulse cleaning system to make sure it is working normally.
- Confirm dust bin is not overfilled; clean it once per shift if needed.
4. Check Sealing System of the Machine
Good sealing ensures abrasive is not leaking outside.
- Inspect rubber seals, side seals, front and rear seals for cracks or abrasion.
- If sealing strip is damaged, replace in time.
- Look for abrasive leakage on both sides of blasting head.
5. Lubrication Work Must Be in Place
Daily lubrication can significantly reduce mechanical wear.
- Add proper grease to bearings, drive motor, and blast wheel assembly according to lubrication chart.
- Make sure oil level of gearbox is within standard range.
- If temperature of bearings is too high, stop the machine and check immediately.
6. Inspect Electrical System and Safety Devices
Electrical control is the heart of stable operation.
- Check if control panel, cables, sensors, and start/stop buttons are normal.
- Ensure all safety protection devices are functioning, including emergency stop.
- For abnormal smell, spark, or heating, stop the machine and find the cause.
7. Clean Machine Surface and Working Area
Cleanliness is also part of maintenance.
- Remove accumulated dust, shot abrasive, and debris on the machine surface.
- Ensure the recovery system and magnetic separator area are free of obstruction.
- Keep ground around machine clean to avoid workers slipping.
8. Record Daily Inspection Data
Good maintenance needs good record.
- Record machine running hours, wear part replacement time, and failure history.
- Help engineer judge wear cycle and plan preventive maintenance.
Conclusion
Daily maintenance of the floor shot blasting machine is simple but very critical. If operators strictly follow the above methods, the machine can keep high efficiency, stable blasting effect, and much longer service life. For foundry, steel structure, and floor construction industries, a good maintenance system can directly reduce downtime and improve project quality.
