We talked about the crusher earlier, and today I will tell you about the maintenance of the shredder blade.
Maintenance reasons
Blunt blades will increase the burden on the motor, resulting in increased power consumption and intensified equipment vibration, which is easy to damage the bearing and spindle; Residual metal chips absorb moisture and rust, which will accelerate blade corrosion; The foreign matter stuck or the blade cracked may cause the whole machine failure, and the maintenance cost far exceeds the maintenance cost.
Maintenance methods
1. After stopping the machine every day, use a soft brush to clean the metal debris between the cutter teeth, and do not use alcohol or acetone;
2. When installing the blade, ensure that the flange is clean and the bolts are tightened to 120-140 Nm;
3. Add high-temperature resistant lithium grease every 200-500 hours to lubricate the bearing and connecting surface;
4. If the blade wears 0.2 mm, you should find a professional tool to repair it, instead of using a hand grinding wheel;
5. If the equipment is out of service for more than two days, it should be coated with antirust oil and covered with dust-proof cloth. It should be checked every three days in humid days in Zhengzhou.
Maintenance benefits
1. The service life of the blade is extended from 400 hours to 600-800 hours, saving half of the cost of tool replacement;
2. The downtime is reduced by 70%, the motor is more energy-saving, and the annual electricity bill is over 10%;
3. The discharging is more uniform, and the qualified rate is stable above 85%, without rework and crushing.
