Hammer crusher wear-resistant high speed when a direct blow to the material, eventually breaking into the appropriate material particle size, the hammer is a hammer, one of the core components of alloy composite crusher hammer, arranged in a crusher rotor shaft hammer, hammer Head Crusher at high speed when a direct blow to the material, the degree of wear-resistant hammer is not the same, the head of the need for good wear resistance and toughness of the shank and need adequate, with carbide hammer on the wear performance Good. Due to the harsh, high chrome hammer operation preheating device process prone core positioning and workpiece size is not accurate composite hammer, an increase of product obsolescence rate, so you should pay special attention to the work environment at this stage. When the composite hammer problems, we should be checking, troubleshooting, provided that our products may have some problems for the dual composite hammer, which today is to tell you about the product FAQs and treatment methods, Please read it carefully. 1, bearing overheating reasons: lack of grease; too much grease; grease filthy degenerate; bearing damage. Remedy: Fill the right amount of grease; bearing greases should its space volume of 50%; cleaning bearings; replace the grease; replace bearings. 2, the expected size is too big reason: composite hammer FAQ excessive wear and treatment methods; screen bar break. Remedy: replace the hammer; replace screen bar. 3, elastic coupling to generate percussion reason: pin loosening; elastic ring wear. Remedy: Stop the pin and tighten the nut; replace the elastic ring. 4, reduced production reasons: sieve slits blocked; feeding uneven. Remedy: parking, cleaning sieve slits of obstruction; adjust the feed mechanism. 5. The amount of vibration suddenly reason: When replacing the composite hammer Frequently Asked Questions treatment or because of wear cone rotor static balance undesirable; hammer broken rotor imbalance; pin bending, breaking; triangular plate or disc cracks; bolt umbrella. Remedy: Remove the hammer, hammer weight selection, so each shaft hammer hammer hammer axis relative to its total weight of the total weight of the hammer equal, that meet the requirements of static equilibrium; replace the hammer; replace the pin; welding repair or replacement; fastening bolt.
