Hammer crusher, precise definition should be the hammer crusher hammer, hammer is one of the core parts of hammer crusher, hammer arranged on the rotor shaft crusher, hammer crusher when a direct hit at high speed material, eventually broken into suitable material size. Hammer crusher on the market according to the manufacturing process can be divided into two types: casting and forging, but they are not the same degree of abrasion resistance. Because of the broken material, the head of the need for good wear resistance and toughness shank also need enough, usually steel, high manganese, chromium cast iron heightening bimetallic composite materials such as forging or casting a molding method, coupled with appropriate heat treatment process is a little more economical, hammer crusher can be divided according to the material types: high manganese steel hammer, hammer bimetallic composite hammer, big gold teeth hammer, hammer of chromium alloy, carbide Hammerhead other major factor is the content of silica under modern industrial technology show that: in the hammer with carbide wear good performance. Hammer crusher invention dating back more than 100 years of history, through continuous improvement and innovation, has been widely used in cement, coal preparation, power generation, metallurgy (sintering and coking), refractory and other industrial sectors. Hammer crusher is broken by the shock effect to the material. When the material to the crusher hammer parts, immediately met with high-speed rotary hammer crusher crushing blow. In the original production of composite hammer hammer on, beyond the conventional adding a lot of precious and rare alloy produced can resist harsh abrasive wear hammer parts procurement, This is described in detail on the composition of its mold knowledge, I hope you like it. A casting injection systems: liquid metal flows into the cavity of the channel, which is generally by pouring cup, sprue, runner, runner components. 2, outlet eye: in composite hammer mold or mandrel with a needle out of the outlet channel to vent. 3, vent: in which the mold or core for casting formed of a gas is discharged provided grooves or channels. 4, the riser: for feeding casting mold cavity with hammer parts manufacturers, and some also from observing the riser, exhaust and set slag role. 5, the cavity: the cavity part by the hammer mold forming material surrounded by, the main space is formed casting. 6, the core: sand casting part obtained in the interior cavity. Overhanging portion of the core, said core head for positioning and supporting the core. Secondary sand core is placed head cavity, said core holder.
