2014-08-07

Hammer crusher is also called hammer breaker, it is widely used in mining industry, concrete crushing industry, building materials, coal, refractory materials, etc. Currently, hammer crusher plays more and more important role in our daily life, so we need to pay attention to hammer crusher. 

Hammer crusher has high productivity and could bring great benefits to user. In addition, it has high crushing ratio, low electric consumption and simple structure. In fact, it is a perfect combination of jaw crusher and cone crusher. However, its disadvantages are that its abrasion of hammer and grid section is high, metal consumption is large and maintenance time is long. 

As to the daily maintenance of hammer crusher, we should notice many things. In addition to operate it according to the introduction, we also should notice the following questions:
1.Hammer crushers crush the material with the help of high-speed rotation of the hammer. Therefore, the installation of the base and the rotation axis must be strictly stayed on one level. The error of the basic should not more than thousandths of 0.5 mm, the error of the vertical axis vertical should not more than thousandths of 0.1mm.

2. The space between the hammer head and the grid section can be adjusted according to the requirement of the broken size. The requirement of the space adjustment: when the material crushing particle size is 5 mm, the adjustable space is 15-25 mm: when the material crushing particle size is 10 mm, the adjustable space is 10-15 mm. The gap between the grate bars also can be adjusted by increasing or decreasing the gasket according to the requirement particle.

3. During the use of hammer crusher, we should regularly check the liner, hammer and grate bars. If necessary, it should be replaced. If the hammer head is worn, we can repair it with the alloy rod. But the surface of the head should keep balance; otherwise it will cause severe vibration because of the imbalance of the equipment.

4. The replacement of the hammer head must according to the relative position of the hammer head. Otherwise it will cause the imbalance rotation of the rotor.

5. The highest temperature of the rotor should not exceed 70 degrees Celsius. If over 70 degrees Celsius, we should immediately stop the machine and check it.

6. If the bearing seat is adopting thin oil to lubrication, we should add the lubricant to the bearing after it working each eight hours; the oil level should be maintained at the center position of the lowest of the ball, and every three months. The lubricating oil should be replaced every three month.
