Annual overhaul and maintenance of rock wool equipment

2026,09,08

Annual major maintenance and upkeep

1. Overhaul of refractory lining and replacement of water cooling components in the melting furnace.

2. Maintenance and replacement of centrifuge spindle, bearing seat, and spinning wheel assembly.

3. Overhaul of curing furnace body, maintenance of hot air system and dehumidification system; Replace the entire mesh belt.

4. Overhaul the cotton collecting machine and pendulum cotton laying mechanism, replace worn chains, bearings, and belts.

5. Replace the lubricating oil of the entire reducer uniformly; All bearings will be evaluated and replaced.

6. Overhaul of dust removal system, fan maintenance, and replacement of filter material.

7. Dust removal of electrical control cabinet and aging inspection of cables; Verify and calibrate all sensors.

8. Complete machine no-load and linkage testing, calibration of parameters for each section.

Key maintenance points for various key equipment

1. Centrifuge (with the highest failure rate)

-Core: Cooling water, vibration, spinning wheel wear, bearing lubrication.

-Strictly prohibit water shortage operation; Regularly measure vibration; If the erosion of the spinning wheel exceeds the standard, it should be replaced in a timely manner. Do not force production with defects to prevent major accidents such as wheel breakage.

2. Adhesive spraying system

-Resin adhesives are prone to curing, and cleaning pumps, pipelines, and nozzles is the most critical means to reduce pump and nozzle blockages when shutting down.

3. Curing oven

-High temperature+resin volatiles coking, regularly clean the rollers and mesh belts inside the furnace; The dehumidification duct is prone to adhesive buildup and blockage, resulting in uneven furnace temperature and substandard products.

4. Various types of mesh belts (cotton collection, curing oven)

-Key points: prevent deviation and clean surface resin clumps; The joint is a weak point, regular inspection is necessary to prevent belt breakage and shutdown.

5. Dust removal system

-Rock wool fibers are fine and easily clog air ducts. Reserved cleaning doors are provided for air ducts, and dust is cleaned regularly; The ash hopper is strictly prohibited from accumulating too much material.

General precautions

1. The environment is dusty, and motors, sensors, and control cabinets should be regularly dusted to avoid overheating and signal drift.

2. High temperature equipment must not be disassembled under pressure or temperature.

3. Establish a vulnerable parts ledger: spinning wheels, mesh belts, belts, saw blades, nozzles, bearings, seals, and reserve spare parts according to operating hours.

4. Keep good maintenance records, make preventive replacements according to operating hours, do not wait until it breaks before repairing, and reduce unplanned downtime.
