1.Conditions for immediate replacement of the hammer
Pay attention to the visible wear of impact crusher parts. When the edge of the hammer is worn more than 1.5cm (about 1 finger width) or weight loss of more than 1/5 (such as 10kg hammer is only 8kg or less), it means that the wear and tear has affected the performance; Secondly, pay attention to the machine abnormality: the decline in crushing efficiency, vibration intensification, or inexplicable increase of 20% of the electricity bill, often caused by the wear of the hammer 'strike warning'; Finally, be alert to the fatal damage - the alloy version of the hammer will last for 2 months. Lastly, be alert to fatal damage - surface cracks or edge defects (like a biscuit chewed off), the continued use of this situation may trigger fracture, breaking the internal parts of the machine.
2.Extend the life of the hammer
Do not want to frequently change the plate hammer such impact crusher parts, that must be every 1 week to change the upper and lower positions, so that wear and tear more evenly; control the feed size, do not let more than fist size stone into the machine, reduce the impact of the loss of the plate hammer; every day before the start to spend 5 minutes 'physical examination', check whether the screws are loose, whether the surface has new cracks, and whether there is no new cracks, and whether the machine has been used for a long time. Before switching on the machine every day, spend 5 minutes to check whether the screws are loose, whether there are new cracks on the surface, early detection of problems early treatment, to avoid small hairy disease into a big failure.
The life of the hammer is closely related to the material and working conditions, and it is necessary to replace the hammer in time when it is found to be seriously worn or abnormal. Usually more maintenance, reasonable use, so that the plate hammer 'work and rest', not only to reduce the loss of downtime, but also save considerable replacement of the cost of impact crusher parts.
