Maintenance of the feed hammer mill

2023-12-23

The Hammer Mill is a processing machine widely used in agricultural production. However, some people do not strictly follow the procedures during use and neglect maintenance, which not only induces mechanical failure, but also greatly reduces the efficiency of the crushing process. Therefore, when using the crusher, maintenance and maintenance must not be ignored.

1. Check and clean in time. After every day's work, the machine should be cleaned in time to check whether the screws in various parts are loose and whether the wearing parts such as claws and screens are worn.

2. Add grease. The most commonly used is to install a cap-type oil cup on the bearing. Under normal circumstances, you only need to rotate the oil cup cover 1/4 turn every 2 hours to press the grease in the cup into the bearing. For closed bearings, grease can be added every 300 hours. After long-term use, if the grease deteriorates, the bearing should be cleaned and replaced with new grease. When the machine is working, the bearing temperature must not exceed 40°C. If the bearing temperature continues to increase under normal working conditions, the cause should be found and the fault should be eliminated.

3. Carefully clean the raw materials to be crushed. It is strictly forbidden to mix copper, iron, lead and other metal parts as well as larger stones and other debris into the crushing chamber.
4. Do not increase the speed of the grinder at will. Generally, the allowable difference from the rated speed is 8%-10%. When the pulverizer is working with a larger power machine, attention should be paid to controlling the flow and making the flow uniform, and not fast and slow.
5. After the machine is started, it is not allowed to dismantle or inspect any part inside the machine. Various tools must not be placed randomly on the machine. When you hear abnormal sounds, you should stop the machine immediately and wait for the machine to stop before maintenance.
