How to exclude the fault of hammer crusher in stone production line
Stone production line into stone production line, sand production line into two categories. Classification is different from the production line equipment configuration is different. Stone production line used to hammer crusher, then the stone production line in the hammer crusher failure how to exclude:
Hammer Crusher first understand the specific problems
Since the original hammer-axis to prevent the channeling of a fixed block design is unreasonable, leading to a fixed stop bolt easy to break and hammer shaft rotation, the hammer crusher hammer mill shaft-hole hammer on a plate large aperture of l00mm (the original Shaft hole 90), beating the hammer shaft is too large to result hammer shaft fracture, and easy to break the screen of the screen of the aircraft.
Hammer hammer drive shaft fixed at both ends of bolts to block M16, a smaller bolt, a great force, the bolt is easy to break, so hammer hammer shaft axis and the occurrence of breakage.
Approach to these problems
Hammer shaft hole for the hammer plate repair, there are two options. Option One, the hammer crusher hammer plate all remove the 8, the assembly re-produced in a 300x300 square shaft tooling on the bed with a hang hole wok to the original hammer shaft 15, making 64 sleeve (axis sets of diameter 90H11, OD 115), the sleeve onto the cold bore good shaft bore, and then eight hammer drive shaft assembly of the original parties. Option II, non-demolition hammer plate, the original 64 holes with a hammer shaft after welding steel block, re-pan 64 90H11 symmetry axis hole. Third-generation Sand prompt you to: plan a hammer plate assembly as a special way to our existing conditions can not remove hammer plate. Therefore, use of the program two pairs of shaft-hole hammer hammer disc repair. a, original hammer-axis against a fixed stop channeling structure is irrational, we block structure has been improved. b, the original fixed block bolts M16 to M20, and the use of high strength grade bolts. Increase the strength of the bolt block, so that the bolt is not easy to break. c, hammer, hammer drive shaft bolt hole and block after processing, the entire rotor dynamic balance and static balance check, and meet the requirements.
