Hammer crusher Common Faults and exclusion method (Figure) – Dragon Bridge machi
Hammer Crusher Hammer crusher Introduction and Purpose: Hammer crusher is suitable for crushing all kinds of medium hardness and brittle materials, materials to be broken as coal, cement, gypsum, alum, brick, tile and limestone, the material does not exceed 300 MPa compressive strength, moisture not more than 15%, at present, hammer crusher ideal for artificial sand products are widely used.
Hammer crusher working principle of: Hammer crusher with a hammer for the main components (also known as hammer) of the rotor. Rotor from the spindle, disk, composed of pin and hammer. Motor drives the rotor cavity in the broken high-speed rotation. Material from the upper inlet into the machine by high-speed movement of the hammer blow, impact, shear, abrasive and grinding. The lower part of the rotor, with sieve plate, crushing material in less than sieve size fractions discharged through the sieve, sieve size larger than the coarse-grained materials remain in the sieve on the resistance continues to be a hammer blow and cut, and finally through Sieve discharged outside the machine.
Hammer crusher failure and exclusion: 1, Bearing Overheat Reasons: lack of grease; grease too; grease filthy degenerate; bearing damage.
Exclusion method: add the word appropriate grease; bearing Yun-fat should be 50% of its space volume; cleaning bearings; replacement of grease; replacement.
2, the particle size is too large
Reasons: excessive wear hammer; screen faults.
Remedy: replace the hammer; replacement screen section.
3, reduced production Reasons: Screen section gap was blocked; feeding uneven.
Remedy: parking, clean-up slot in the plug section sieve material; adjust the feeding sector.
4, elastic coupling produces percussion Reasons: pin loosening; elastic ring wear;
Exclusion method: stop and tighten the pivot nut; replacement elastic ring.
5, the machine internally generated percussion
Reasons: non-breaking material into the inside of the machine; liner fasteners loose, hammer impact on the liner; hammer or other parts broken.
Remedy: parking, clean up the crushing chamber; check the lining of the tightening situation and hammer and the gap between the screen section; to replace broken parts.
6, the machine vibration Reasons: to replace hammer or cone when the wear to the rotor static balance sub-request; hammer broken rotor imbalance; pin bending and breaking; Triangle Park, disk drive or cracks; in foot Bolt Loose.
Remedy: Remove the hammer, by weight, select the hammer, so that each shaft hammer hammer hammer axis relative to its total weight of the total weight of the hammer, that meet the requirements of static equilibrium; replacement hammer; replacement sales axis; welding repair or replacement; fastening bolt.
