What Are Some Common Shredder Machine Installation Issues That Need Attention?

I. Site Foundation Issues

1. The ground was not hardened or reinforced; installation directly on ordinary soil or thin cement surfaces will cause severe vibrations during operation, potentially leading to equipment displacement and bearing damage.

2. Excessive site flatness errors; failure to use a level to calibrate the machine's levelness will result in cutter shaft misalignment and uneven blade wear over time.

3. Insufficient space for maintenance and material storage will lead to insufficient operating space for blade replacement and material clearing, sometimes requiring wall demolition for maintenance.

II. Component Installation Issues

1. Failure to clean the cutter shaft and cutter box contact surfaces before installation will leave residual debris and oil, causing dynamic imbalance and severe vibrations during operation.

2. Blades were not weight-matched; excessive weight differences between individual blade groups will cause strong vibrations during operation and shorten bearing life.

3. Bolts were not tightened diagonally with a torque wrench; individual bolts may be overtightened or loosened, increasing the risk of bolt breakage and blade detachment during operation.

4. Improper adjustment of the transmission chain and belt tension, causing the driving and driven pulleys to be misaligned, resulting in slippage and deviation during operation.

III. Electrical and Debugging Issues

1. Insufficient power supply line diameter, not configured with a margin of 1.5 times the equipment's rated power, leading to unstable voltage during operation and potential motor burnout.

2. Incorrect motor wiring phase sequence, causing the cutter shaft to reverse, not only preventing normal feeding but also directly damaging the blades.

3. Feeding material without conducting a no-load test run, failing to address potential issues such as equipment jamming and abnormal noises beforehand, directly causing material blockage and component damage after startup.

4. No-load test run duration less than 30 minutes, failing to confirm that bearing temperature rise and vibration values ​​are within normal ranges before directly entering full-load production.

IV. Safety and Environmental Issues

1. Lack of protective covers on transmission parts, leading to accidental contact with rotating components and potential safety accidents.

2. Lack of dust removal and noise reduction facilities, resulting in excessive dust and noise levels during operation, failing to meet local environmental protection requirements.

3. The grounding resistance is not up to standard and no leakage current protection device is installed, posing safety hazards such as leakage current and lightning strikes.
