Description
Technical field
This utility model relates to mining machinery field, particularly a kind of mine disintegrating machine.
Background technology
In the recovery process in mine, need to carry out Ore to crush, refine, the operation such as screening, and wherein broken undoubtedly
Being the first step of whole operation, Ore only has the most just can carry out follow-up Refinement operation, and therefore shattering process seems outstanding
For important；Just because of this, disintegrating machine is widely used in mining.At present, disintegrating machine has a variety of, but due to Ore
Hardness so that the parts wear of disintegrating machine is serious, it is often necessary to change accessory, reduce its life-span and have a strong impact on
Production efficiency.
Bar be disintegrating machine for crushing the vitals of bar, bar abrasion is the main failure forms of disintegrating machine, one
As service life of bar short, consumption is big. needing to lay in substantial amounts of spare part and could maintain normal production, production cost is high, makes
The reason becoming bar service life short typically has two: one, and to be that bar material selects improper.Bar material should use resistance to break-in
Gold copper-base alloy, but existing bar the most all uses potassium steel to make, and potassium steel hammer head of hammer crusher has good toughness, technique
Property good, price is low, and it is mainly characterized by under the effect of bigger impact or contact stress, and it is hard that surface layer will produce rapidly processing
Changing, its work hardening index is higher than other material 57 times, and wearability is greatly improved, but potassium steel tup is to broken
Broken machine overall performance requires higher, if physical impact power is inadequate or contact stress is little in real work, then can not make surface
Produce rapidly processing hardening, thus can not play its due wearability；The most again it has been proposed that high-chromium alloy plate hammer for crusher,
High-chromium wear-resistant bar feature is good toughness, intensity height, good manufacturability, has certain hardness, and high thermal hammer head, in bigger impact
Or contact stress effect undersurface layer will produce rapidly violent processing hardening. it is greatly improved case hardness and anti-wear performance, but
High-chromium alloy toughness is poor, is susceptible to fracture in the case of not having hammer carrier to support.Still can not overcome lacking of homogenous material
Point.
High vanadium wear resistant alloy material has developed 10 years the most has a surplus, and it has excellent wearability, good matrix group
Knitting, excellent mechanical performance, therefore as a new generation's high-abrasive material, high vanadium antifriction alloy the most all receives much concern, in state
In, high vanadium wear resistant alloy material is in development, exploitation and the starting stage of production application, has been used for roll, ball mill
In the multiple wearing piece such as liner plate and rotor block, but applying on bar the most very little, in order to improve the wearability of bar, bar becomes
Divide and gradually develop to high-carbon height vanadium direction, and nowadays, V-Ti is described as third generation vanadium alloy, the most preferably applies vanadium
Titanium alloy is also the direction that scientific research personnel studies always.
