Abstract
Hammer crusher is widely used in cement, ceramic, mining and electricityother industries, hammer head is one of important parts in crusher, its abrasion performance directly affects the service life of hammer crusher and economic cost. According to bimetalcomposite hammer head is often appear “Hammer handle wear and tear”,“Composite difficult” and the set of casting alloy block hammer head set piece of “come off” phenomenon, which design a set piece type bimetal composite casting straight diagonal hammer, make full use of high chromium cast iron wear resistance and the toughness of low alloy steel. Design a protect block structure reasonably that solve the hammer when the actual production of composite interface is difficult to control and “the problem of hammer head wear” for use. Solve the problem of hammer head wear actively, achieve “energy saving, emission reduction and environmental protection”.
Highlights
Hammer crusher iswidely used to cement, metallurgy, mining, coal, building materials, transportation and other industries, mining of the ore is high speed rotating hammer broken into grinding material, the workload is very heavy.Hammer crusher is one of the shortest life and the biggest parts of consumption
High manganese steel was made earlier crusher hammers and common one kind of material, but some broken material impact is not strong,the work hardening of high manganese steel can't display,high manganese steel wear fast, short service life and so on problems, and Single material of hammer head can't meet the needs of high toughness and high wear resistance
2.1 Determine the structure This paper studies the with a piece of straight bevel type hammer handle, It contains the hammer side and with the hammer handle, hammer side is equipped with right angle trapezoid structure to protect the handle
Summary
Hammer crusher iswidely used to cement, metallurgy, mining, coal, building materials, transportation and other industries, mining of the ore is high speed rotating hammer broken into grinding material, the workload is very heavy.Hammer crusher is one of the shortest life and the biggest parts of consumption. High manganese steel was made earlier crusher hammers and common one kind of material, but some broken material impact is not strong,the work hardening of high manganese steel can't display,high manganese steel wear fast, short service life and so on problems, and Single material of hammer head can't meet the needs of high toughness and high wear resistance. Cast in alloy block hammer head often set piece of "come off", Bimetal composite hammer head is often appear "Hammer handle wear and tear" and "Composite difficult" phenomenon. According to the above problems, this paper designs a with a piece of straight bevel type hammer handle, with good abrasion resistance of high carbon high chromium steel manufacturing. Handle piece, hammer end work part adopts high wear resistance of high chromium cast iron, hammer handle part adopts good toughness of low alloy steel. Give full play to the material and cast-in superiority, solve the problem of hammer head production and application in [1]
