Hammer crusher is mainly depending on the impact to break material, the material into the crushing subjected to high-speed rotary hammer impactcrushing machine.Broken material obtain kinetic energy to rush to the frame body baffle stripsat the same time the material impact each other by multiple broken less thanbetween the screen bars gap materials discharged from the gap from thehead office.

Performance characteristics of hammer crusher:Hammer crusher has the advantages of compact structure, high efficiency,high crushing ratio, convenient operation and maintenance, uniform product size, less crushing, widely used in building materials, coal, metallurgy, power generation and other industrial sectors.he main counter pressure is less than 120Mpa ore, coal, coke, gypsum and other hard and soft materials, fine.

Hammer crusher has the advantages of compact structure, reasonable layout, convenient installation, good maintainability, simple operation,especially the adaptability of cement production process excellent layout,saving the process layout space, has the special feature of the materialcrushing etc.

Breaking reason and the elimination method

1,the bearings overheatingReason: Grease deficiency; excess grease; lubricating grease contaminationdeterioration; bearing damage.Method: the filling amount of grease; bearing grease should be the space volume 50%; cleaning bearing; replace the grease; replacement of bearings.

2,powder through the largeReason: hammer wear large screen faults.Remedy: replace the hammer; replacement of screen.

3,reduceyieldReason: the sieve gap is blocked; feeding non-uniformity.Troubleshooting: parking, cleaning sieve plug gaps in adjusting the feeding mechanism.

4, elastic coupling produces percussion sound .Reason: pin loosening; elastic ring wear.Troubleshooting: parking and tighten the pin shaft nut; the replacement ofthe elastic ring.

5, inside the machine produces percussion sound.Reason: the non crushing matter into the inside of the machine; panelfasteners loose, hammer impact on the lining plate; fracture hammer or other parts.Troubleshooting: parking, clean the crushing chamber; the fastening andhammer inspection liner and the sieve gap between; replacement of brokenparts.

6, the machine vibrationReason: replacing hammer or the cone head wear the rotor static balanceundesirable; hammer broken, rotor unbalance; the pin shaft bending,breaking; triangular plate or disc crack; anchor bolts loosening.Method: remove the hammer, hammer according to the weight selection, so that each weight hammer shaft hammer and hammer hammer shaft is equal to the total weight, i.e. static balance to meet the requirements; replacinghammer pin shaft; replacement; welding repair or replacement; the fasteningbolt.
